Answers

Answer 1

Answer:

A

 [tex]k = 0.11 \ m [/tex]  beyond the goal  post

B

Given that the goal  was score against the Bruins it then means that the Flyer won the game with 2 points

Explanation:

From the question we are told that

  The amount of time left in the game is  [tex]t =  20 \ s[/tex]

   The  amount of time the goal was defended  is  [tex]t_1  =  9 \  s[/tex]

   The  time remaining when the shot was made is  [tex]t_2 =  1.25 \  s[/tex]

     The  distance of the pluck from the goal is  [tex]d =  37 \  m[/tex]

     The  initial  velocity of the pluck is [tex]u =  30 \  m/s[/tex]

    The acceleration of the pluck is  [tex]a =  -0.50 \  m/s^2[/tex]

Generally the distance travel at the remaining time is mathematically represented as

      [tex]D =  u *  t _2  +  \frac{1}{2}* a*  t_2[/tex]

      [tex]D =  30 * 1.25  - \frac{1}{2}* 0.50* 1.25^2[/tex]

       [tex]D =  37.11 \ m [/tex]

So the position of the pluck when the game clock reaches zero is

        [tex]k = D - d[/tex]

=>    [tex]k = 37.11 - 37[/tex]

=>        [tex]k = 0.11 \ m [/tex]  beyond the goal  post

Given that the goal  was score against the Bruins it then means that the Flyer won the game with 2 points

Answers

Answer:

The values are [tex]I_L  =  500.37 \ mL / minutes [/tex]

and [tex]I_r  = 299.63 \ mL / minutes [/tex]  

Explanation:

From the question we are told that  

   The pressure at the bifurcation of the femoral artery is  [tex]P = 100\ mm\ Hg[/tex]

   The pressure at the left or right femoral artery is  [tex]P_r = P_l  =  10 \  mm \  Hg[/tex]

   The resistance in the  left femoral artery is  [tex]R_L[/tex]

   The resistance in the  right  femoral artery is  [tex]R_r =  1.67 R_L[/tex]

   The total  flow rate is  [tex]I = 800 mL/minute[/tex]

The diagram illustrating this question is shown on the first uploaded image

Generally this flow of blood through the artery can be compared to the a circuit as shown on the first uploaded image

Generally the rate at which blood flows through the  left femoral artery is mathematically represented as

      [tex]I_L  =  I * \frac{R_r }{R_L + R_r}[/tex]

=>      [tex]I_L  =  800 * \frac{1.67 R_L }{R_L + 1.67 R_L}[/tex]

=>    [tex]I_L  =  800 * \frac{1.67 R_L }{2.67 R_L}[/tex]

=>    [tex]I_L  =  500.37 \ mL / minutes [/tex]

Generally the rate at which blood flows through the  right  femoral artery is mathematically represented as

      [tex]I_r  =  I * \frac{R_L }{R_L + R_r}[/tex]

=>      [tex]I_r  =  800 * \frac{R_L }{R_L + 1.67 R_L}[/tex]

=>    [tex]I_r  =  800 * \frac{ R_L }{2.67 R_L}[/tex]

You observe two cars traveling in the same direction on a long, straight section of Highway 5. The red car is moving at a constant vR equal to 34 m/s and the blue car is moving at constant vB equal to 28 m/s. At the moment you fist see them, the blue car is 29.0 m ahead of the red car.

Required:
a. How long after you first see the cars does the red car catch up to the blue car?
b. How far did the red car travel between when you fist saw it and when it caught up to the blue car?
c. Suppose the red car started to accelerate at a rate of a equal to 5/3 m/s^2 just at the moment you saw the cars.
d. How long after that would the red car catch up to the blue car?

Answers

Answer:

a) 3.66 s

b) 124.4 m

c) 3.12s

Explanation:

Given that

Speed of the Red Car, v₁ = 34 m/s

Speed of the Blue Car, v₂ = 28 m/s

Distance between the two cars, d = 22 m

The difference between the speed of the cars is: 34 - 28 = 6 m/s

From this, we can deduce that the red car will be catching up to the blue car at a speed of 6 m/s.

1)

If we divide the distance by the difference in speed. This becomes

d/v = 22/6 = 3.66 s. Which means, It takes 3.66 seconds for the red car to meet up with the blue car.

2

From the previous part, we were able to confirm that it took 3.66 seconds for the red car to meet up the blue car. Also, the speed with which it were traveling was travelling at, was constant, so we only need to multiply it by the time from (1) to get the distance.

v = d * t = 34 * 3.66 = 124.4

Therefore the red car travels at 124.4 m before catching up to the blue car.

3

If the red car starts to accelerate the moment we see it, the time it will take, to get to the blue car will be less than what we had gotten. We can find this using one of the equations of motion.

S = ut + ½gt², where

S = 22

u = 6

t = ?

g = 2/3

22 = 6t + 1/3t²

By using the quadratic formula, we find out the two answers listed below

t1 = 3.12 s

t2 = - 21.12 s

We all know that negative time is not possible, so the answer is t1. At 3.12 seconds

Analysis of an accident scene indicates a car was traveling at a velocity of 70.0 mph (31.3 m/s) along the positive x-axis at the instant the brakes were applied and then traveled a distance of 115 m before hitting an obstacle at a velocity of 4.65 m/s. Determine the car's acceleration a (assumed constant) and the time t between applying the brakes and hitting the obstacle. (Assume the car is moving in the positive direction. Indicate the direction with the sign of your answer.)

Answers

Answer:

The acceleration of the car is -4.166 m/s²

The time between applying the brakes and hitting the obstacle is 6.4 s

Explanation:

Given;

initial velocity of the car when the brake was applied, u = 31.3 m/s

final velocity of the car after hitting an obstacle, v = 4.65 m/s

distance traveled before stopping, s = 115 m

The acceleration of the car is given by;

v² = u² + 2as

2as = v² - u²

a = (v² - u²) / 2s

a = (4.65² - 31.3²) / (2 x 115)

a = -4.166 m/s²

The time between applying the brakes and hitting the obstacle;

v = u + at

at = v - u

t = (v - u) / a

t = (4.65 - 31.3) / -4.166

t = 6.4 s

Tension is actually a force that tends to

Answers

Answer:

Pull towards itself.

Explanation:

That's what I know.

Tension is a force that tends to pull or stretch an object. A flexible material, like a rope, cable, or string, is used to transmit the force.

A force known as tension has a tendency to pull or stretch an object. When a flexible medium, like a rope, cable, or string, is under strain and supporting an imposed load or weight, it transmits force via the flexible medium.

A rope or cable that is under tension receives equal and opposing forces pulling it in different directions at either end. For instance, the tension in a rope will be the same along its whole length if both ends are pulled with equal effort.

When you use a pulley system to hoist a weight, suspend an object from a rope, or support the weight of traffic on a bridge, tension can be present.

Therefore, Tension is a force that tends to pull or stretch an object.

Answers

Answer:

a) F= 0,19  [N]   according to problem statement

b) F = 0,19*10⁹ [N]  using the right value of K

Explanation:

The force between two electric charges is according to Coulomb´s law is:

F = K * q₁*q₂ / d²    where  q₁  and q₂ are the charges on body one and body 2 respectively, d is the distance between the two bodies and K is a constant  K = 8,988100*10⁹ N.m²/C². The problem establishes to use        K = 8,988100 N.m²/C².

NOTE: To value of is :  K = 8,988100*10⁹ N.m²/C². I am going to solve the problem using K = 8,988100 N.m²/C² if that information was an error, all we need to get the right answer is multiply the result by 10⁹

Then:

F = 8,988100 * 1,2* 0,36 / (4,5)²     [ N*m²/C² ] * [ C*C*/m²]

F = 3,882859/ 20,25  [N]

F= 0,19  [N]

The force is of repulsion since the two charges are positive and in the direction of the straight line which passes through the centers of the bodies

b. 40.0 cm along the axis of the 10 cm ring.

Answers

Answer:

a)     Eₓ = 0  ,   b)    c)    Ex_total = 3.96 10⁻⁶ N

Explanation:

For this problem we will look for the expression for the electric field of a ring of charge, at a point on its central axis.

From the symmetry of the ring, the resulting field is in the direction of the axis, we suppose that it corresponds to the x and y axis and the perpendicular direction but since the two sides of the annulus are offset.

       dE = k dq / r²

The component of this field in the direction to x is

       d Eₓ = dE cos θ

the distance of ring to the point

        r² = x² + a²

where a is the radius of each ring

the cosine is the adjacent leg between the hypotenuse

       Cos θ = x /r

we substitute

   d Ex = k / (x² + a²)  dq      x /√ (x² + a²)

we integrate

      Ex = ∫  k / (x² + a²)^{3/2}  x dq

      Ex = k x/ (x² + a²)^{1.5}   Q

the total field is the sum of the fields created by each ring, since they are on the same line (x-axis), you can perform an algebraic sum

     Eₓ_total = Eₓ₁ + Eₓ₂

a) at the origin x = 0

           in field is zero, since the numerator e makes zero

              Eₓ = 0

b) for point x = 40.0cm = 0.400 m

we substitute the values ​​in our equation

       Ex_total = k x [Q (x² + 0.1²)^{1.5} + 2Q / (x² + 0.2²2) ^3/2]

        Ex_total = k Q x [1 / (x² + 0.01)^1.5 + 2 / (x² + 0.04)^1.52]

         

let's calculate

       Ex_total = 9 10⁹ 30 10⁻⁹ 0.40 [1 / (0.4 2 + 0.01) 3/2 + 2 / (0.4 2 + 0.04) 3/2] 10⁻⁹

       Ex_total = 108 [14.2668 + 22.36] 10⁻⁹

       Ex_total = 3.96 10⁻⁶ N

Answers

Answer:

A.) 22.12 m/s

B.) 3.27 m

C.) 0.57

Explanation:

Given that a mass of 0.4 kg is dropped from rest in a medium offering a resistance of 0.2|v|, where is measured in meters per second. Acceleration due to gravity is 9.8 m/s^2.

a. If the mass is dropped from a height of 25 m, its initial velocity U will be equal to zero. when it hits the ground, the final velocity V will be:

V^2 = U^2 + 2gH

Substitute g and the height into the formula

V^2 = 2 × 9.8 × 25

V^2 = 490

V = 22.12 m/s

b. If the mass is to attain a velocity of no more than 8 m/s, the maximum height from which it can be dropped will be calculated by using the same formula.

V^2 = U^2 + 2gH

Where V = 8 m/s and U = 0

8^2 = 0 + 2 × 9.8 × H

64 = 19.6H

H = 64/19.6

H = 3.27 m

c. Suppose that the resistive force is k|v|, where v is measured in m/s, and k is constant. If the mass is dropped from a height of 25 m and must hit the ground with a velocity of no more than 8 m/s, determine the coefficient of resistance that is required.

The energy at 25m heigh will be:

E = mgh

E = 0.4 × 9.8 × 25

E = 98 J

1/2mv^2 = 98

1/2 × 0.4 × ( 8 - v )^2 = 98

0.2( 8 - v )^2 = 98

( 8-v)^2 = 98/0.2

( 8 - v )^2 = 490

8 - v = 22.12

v = 22.14 - 8

v = 14.14

Coefficient of resistance required will be 8/ 14.14 = 0.57

As it rises, it starts to lose kinetic energy as it transforms into gravitational potential energy as the ball is fighting against the force of gravity as it moves further away from the Earth's surface. This means it begins to slow down until its speed is 0, its highest point, before falling and gaining kinetic energy again. Because of this, we can eliminate options 1, 2 and 5 as we know the ball's velocity decreases as it rises.

As the ball rises it's velocity decreases at a constant rate, as the amount of kinetic energy it has is proportional to its height. Therefore, the best option is option 3, as it states it is decreasing and gives a constant deceleration rate.

Which would be harder to move: a kilogram of feathers or a kilogram of bricks? Explain your answer.

Answers

Answer:

The kilogram (kg) is the SI unit for mass. Not weight.

So when you say « heavier » and mention kg, I would assume you’re talking about mass.

The mass of 1 kg of feathers and 1 kg ok bricks are identical.

And if you want an answer to your question comparing the weight on Earth of those 2 items, in vacuum of one kilogram of feathers would have exactly the same weight as one kilogram of bricks.

The lower the angle of the slope, ________ the acceleration along the ramp, therefore, the speed at the bottom of a slope will be_______, and, consequently, the control will be better.
The acceleration along the ramp, therefore, the speed at the bottom of a slope will be:__________
a. lower
b. gcostheta
c. higher
d. gsintheta

Answers

Answer:

Lower

Lower

gsintheta (gsinθ)

Explanation:

The sum of forces resolved parallel to the inclined plane is given by;

F - mgsinθ = 0

ma - mgsinθ = 0

ma = mgsinθ

a = gsinθ

Acceleration is proportional to angle of inclination, thus the lower the angle of the slope, lower the acceleration along the ramp.

therefore, the speed at the bottom of a slope will be lower, (velocity is directly proportional to acceleration) and, consequently, the control will be better.

The acceleration along the ramp, is gsintheta (gsinθ)

Which describes how the spring constant affects the potential energy of an object for a given displacement from an equilibrium position?
A the higher the spring constant, the greater the gravitational potential energy.
B The lower the spring constant, the greater the gravitational potential energy.
C The higher the spring constant, the greater the elastic potential energy.
D The lower the spring constant, the greater the elastic potential energy

Answers

Answer:

Based on the answer choices provided, the correct answer is:

C, The higher the spring constant, the greater the elastic potential energy.

Explanation:

The spring constant is best defined as the measure of a spring's resistance to force (in regards to factors such as stretching and compression).

Thus, the higher the spring constant, the stiffer the string - this equates to greater elastic potential energy (think of stretching a rubber band or using it as a slingshot).

Hope this helps!

Answer:

C.) The higher the spring constant, the greater the elastic potential energy.

Explain why the driver's reaction time affects the thinking distance.

Answers

Answer:

The thinking distance depends on the reaction time of the driver which could can affected by alcohol, distractions and tiredness. A faster speed increases both thinking  distance, increasing the total stopping distance.

I hope this is helpful. Would appreciate if you add me as brainliest.

A faster pace extends both the thinking distance and the total stopping distance.

Given that,
To justify, the driver's reaction time affects the thinking distance.

What is reaction time?

The reaction time of an organism is a measure of how quickly it responds to a signal. The time interval between the presentation of the stimulus and the appearance of the appropriate voluntary response in the subject is defined as the RT.

The thinking distance is determined by the driver's reaction time, which can be influenced by drinking, distractions, and fatigue. A higher speed increases both thinking distance and total stopping distance.

Thus, A faster pace extends both the thinking distance and the total stopping distance.
