Answer:

KE = [tex]\frac{1}{2}[/tex] m[tex]v^{2}[/tex]

Explanation:

In the generation of energy from hydroelectric power station, the motion of water, and the turbines are paramount. The falling flowing water turns the blades of the turbine, which in-turn causes the movement of a coil within a strong magnetic field.

The motion of the coil which cuts the strong magnetic field induces current. Thus, the system generates electrical energy.

The equation that links kinetic energy (KE), mass (m) and speed (v) can be expressed as:

KE = [tex]\frac{1}{2}[/tex] m[tex]v^{2}[/tex]

A man is using a fishing rod to catch fish in figure 1.

Figure 2 is a simplified diagram of figure 1 with the forces and distances.

Calculate the force F, in figure 2.

Answers

Answer:

Explanation:

Remark

In general, these 3rd class levers are very inefficient. Because the force distance is smaller than the load distance, you need to pull upward with more force that the weight of the load. So whatever the load is, the force is going to be much greater.

The distances are always measured to the pivot unless you are asked something specific otherwise.

Givens

F = ?

weight = 6N

Force Distance = F*d = 0.5 m

Weight Distance =W*d1 = 2 m

Formula

F*Fd = W*Wd

Solution

F*0.5 = 6 * 2            Divide by 0.5

F = 12/0.5

F = 24 N upwards

A car moving with an initial velocity of 36 m/s slows down at a constant rate of -2.8 m/s^2 . What distance does the car travel after 3 seconds of deceleration? Remember to include units in your answer! *

Answers

Answer:

the distance covered by the car is 95.4 m.

Explanation:

Given;

initial velocity of the car, u = 36 m/s

acceleration of the car, a = -2.8 m/s²

time of motion of the car, t = 3 s

The distance covered by the car is calculated as;

s = ut + ¹/₂at²

s = 36(3) + ¹/₂ x (-2.8)(3)²

s = 108 - 12.6

s = 95.4 m

Therefore, the distance covered by the car is 95.4 m.

A 4.50 kilogram block of wood at 20.0°C is uniformly heated using 90,000. joules of heat. What will be the resulting
temperature of the block? (Cp for wood = 1,800. J/kg-°C)

Answers

Answer:

Final temperature, T2 = 31.11°C

Explanation:

Given the following data;

Mass = 4.5kg

Initial temperature = 20°C

Quantity of heat = 90000J

Specific heat capacity = 1,800. J/kg-°C

To find the final temperature;

Heat capacity is given by the formula;

[tex] Q = mcdt[/tex]

Where;

Q represents the heat capacity or quantity of heat.

m represents the mass of an object.

c represents the specific heat capacity of water.

dt represents the change in temperature.

Making dt the subject of formula, we have;

[tex] dt = \frac {Q}{mc} [/tex]

Substituting into the equation, we have;

[tex] dt = \frac {90000}{4.5*1800} [/tex]

[tex] dt = \frac {90000}{8100} [/tex]

dt = 11.11°C

Now, to find the final temperature T2;

But, dt = T2 - T1

Substituting into the equation, we have;

T2 = 11.11 + 20

Final temperature, T2 = 31.11°C

A 2.0 kg cart has a momentum of 10.0 kg m/s. What is its velocity?


A.)22 m/s

B.) 2.0 m/s

C.) 5.0 m/s

D.) 20. m/s

Answers

Answer:

[tex]\boxed {\boxed {\sf C. \ 5.0 \ m/s}}[/tex]

Explanation:

Momentum is the product of mass and velocity. The formula is:

[tex]p=mv[/tex]

The mass of the cart is 2.0 kilograms. The momentum is 10.0 kg m/s. The velocity is unknown.

[tex]m= 2.0 \ kg \\p= 10.0 \ kg \ m/s[/tex]

Substitute the values into the formula.

[tex]10.0 \ kg \ m/s= (2.0 \ kg ) v[/tex]

We want to solve for the velocity (v). Therefore we must isolate the variable. It is being multiplied and the inverse of multiplication is division. Divide both sides of the equation by 2.0 kg.

[tex]\frac { 10.0 \ kg \ m/s}{2.0 \ kg}=\frac{(2.0 \ kg )v}{2.0 \ kg}[/tex]

The kilograms will cancel each other out.

[tex]\frac { 10.0 \ m/s}{2.0}=v[/tex]

[tex]5.0 \ m/s=v[/tex]

The velocity is 5 meters per second.

The force of the pulley is 652 newtons. It accelerates at 53 m/s. How much does the object weigh. a 1230 grams b 1.230 gram c 123.0 grams d 12.30 Grams

Answers

Answer:

d. 12.30 grams

Explanation:

Given the following data;

Force = 652 N

Acceleration = 53 m/s²

To find how much the object weigh, we would need to determine its mass;

Force = mass * acceleration

652 = mass * 53

Mass = 652/53

Mass = 12.30 grams.

Therefore, the object weighs 12.30 grams.

Explanation:

An Electromagnet is called as a temporary magnet, because electromagnet is made up of insulated copper wire wrapped around soft iron, which allows current to flow in it and at that moment iron gains it magnetic properties and when the current is switched off, then there will be no flow of current and hence iron loses its magnetic properties.  

Hence it works temporarily as long as electric current flows in a conductor and hence known as temporary magnet. .

A man who weights 900 N stands on a platform scale in a elevator the elevator has made 4000 kg the reading on the scale is 700 N

Answers

Answer:

a = -2.17 m / s²

Explanation:

In this problem you must ask for the acceleration of the elevator.

Let's use Newton's second law

           F-W = ma

           a =[tex]\frac{F}{m} - g[/tex] F / m-g

the weight of the body is 900 N and the force is the reading of the scale, let's find the mass

         w = mg

         m = w / g

         m = 900 / 9.8

         m = 91.84 kg

let's calculate

         a = 700 / 91.84 - 9.8

         a = -2.17 m / s²

The negative sign indicates that the elevator is going down

2. A football kicked 11.5 meters in the air gains
63.25J of GPE. What is the mass of the football?
3. Explain, using calculations, why a pole vaulter
who competes on another planet wouldn't have
the same GPE as on Earth.

Answers

Answer:

1. m  = 40 kg

2. m = 0.55 kg

3. Because of the different values of acceleration due to gravity, g, on the planet and the earth.

Explanation:

1. GPE = 12000 J

h = 30 meters

g = 10 m/[tex]s^{2}[/tex]

But,

GPE = mgh

where: m is the mass, g is the acceleration due to gravity, and h is the height.

12000 = m x 10 x 30

12000  = 300 m

m = [tex]\frac{12000}{300}[/tex]

   = 40 kg

The mass of the diver is 40 kg.

2. GPE = 63.25 J

h = 11.5 meters

g = 10 m/[tex]s^{2}[/tex]

GPE = mgh

63.25 = m x 10 x 11.5

63.25 = 115 m

m = [tex]\frac{63.25}{115}[/tex]

   = 0.55 kg

The mass of the ball is 0.55 kg.

3. The pole vaulter's GPE on the earth would not be the same as that on another planet due to the variation in the value of the acceleration due to gravity on the two planets, even if he cover the same height.

Given that: m = 60 kg, h = 25 m, determine the GPE on the earth that has g = 10 m/[tex]s^{2}[/tex], and another planet with g = 6.5 m/

Thus, on the earth;

GPE = mgh

       = 60 x 10 x 25

       = 15000

GPE = 15000 J

On the planet;

GPE = mgh

       = 60 x 6.5 x 25

       = 9750

GPE = 9750 J

A cannonball is fired perfectly horizontally from the top of a 210 m tall cliff. It is fired with an initial velocity of 50 m/s. What is the horizontal distance covered by the cannonball before it hits the ground?

Answers

Answer:

the horizontal distance covered by the cannonball before it hits the ground is 327.5 m

Explanation:

Given;

height of the cliff, h = 210 m

initial horizontal velocity of the cannonball, Ux = 50 m/s

initial vertical velocity of the cannonball, Uy = 0

The time for the cannonball to reach the ground is calculated as;

[tex]h = u_yt - \frac{1}{2} gt^2\\\\h = 0 - \frac{1}{2} gt^2\\\\t = \sqrt{\frac{2h}{g} } \\\\t = \sqrt{\frac{2\times 210}{9.8} }\\\\t = 6.55 \ s[/tex]

The horizontal distance covered by the cannonball before it hits the ground is calculated as;

[tex]X = U_x \times \ t\\\\X = 50 \times \ 6.55\\\\X = 327.5 \ m[/tex]

Therefore, the horizontal distance covered by the cannonball before it hits the ground is 327.5 m

A. TRUE
