Answer:

the final angular speed of the wheel at the bottom is 25.5 rad/s

Explanation:

The computation of the final angular speed of the wheel at the bottom is as follows:

As we know that

[tex]W_f = W_{in} + \alpha t\\\\= 2.5 + (2 \times 11.5)\\\\= 2.5 + 23\\\\= 25.5 rad/s[/tex]

Hence, the final angular speed of the wheel at the bottom is 25.5 rad/s

We simply applied the above formula so that the final angular speed could come

Answer:

the correct answer is A,   North

Explanation:

The forces are vectors so they must be added vectorially.

The magnitude of the forces is the same, but not their direction, which is why they are different.

Analyze the situation presented

We have a force towards the North and another towards the South with the same magnitude, therefore these cancel each other out

We have a force towards the Northeast and another towards the Northwest, these can be decomposed into parts, one towards the North and another on the East-West axis, this last component is canceled, but the component towards the North is added.

In summary we see that the body accelerates towards the North

Answer:

a) 378Ns

b) 477.27N

Explanation:

Impulse is the defined as the product of the applied force and time taken. This is expressed according to the formula

I = Ft = m(v-u)

m is the mass = 70kg

v is the final velocity = 5.4m/s

u is the initial velocity = 0m/s

Get the impulse

I = m(v-u)

I = 70(5.4-0)

I = 70(5.4)

I = 378Ns

b) Average total force is expressed as

F = ma (Newton's second law)

F = m(v-u)/t

F = 378/0.792

F = 477.27N

Hence the average total force experienced by a 70.0-kg passenger in the car during the time the car accelerates is 477.27N

Answer:

both magnitude and direction

Explanation:

When an object moves in a circular path, its motion is called uniform circular motion. In this motion, the force acting on it is centripetal force and it is moving under centripetal acceleration. This type of force acts towards the centre of the circle.

In this type of motion, the speed remains constant while the velocity keeps on changing. The object's centripetal  acceleration remains constant in magnitude as well as direction.

Hence, the correct option is (3).

If an object is moving with constant speed in the circular path the object's centripetal  acceleration remains constant in both magnitude and direction

The formula for calculating the centripetal acceleration of an object is expressed as:

[tex]a =\frac{v^2}{r}[/tex]

Hence if an object is moving with constant speed in the circular path the object's centripetal  acceleration remains constant in both magnitude and direction

Answer:

The difference is in who or what is observing the speed.

Explanation:

Giving that speed is relative between the objects and the reference point from which it is being observed.

It is concluded that speed alone has no direct effect on a moving object, hence it is just a determining unit for the difference in distance between two objects.

Therefore, in this case, the difference is in who or what is observing the speed.

Answer:

0.36 kg-m/s

Explanation:

Given that,

Mass of a ball, m = 0.06 kg

Initial velocity of the ball, u = 20 m/s

Final velocity of the ball, v = 26 m/s

We need to find the change in momentum of the tennis ball. It is equal to the final momentum minus initial momentum

[tex]\Delta p=m(v-u)\\\\=0.06\times (26-20)\\\\=0.36\ kg-m/s[/tex]

So, the change in momentum of the ball is 0.36 kg-m/s.

Answer: Things continue doing what they are doing unless a force is applied to it. Objects have a natural tendency to resist change. This is INERTIA. Heavier objects (objects with more mass) are more difficult to move and stop. Heavier objects (greater mass) resist change more than lighter objects, so true

Explanation:

Pushing a bicycle or a Cadillac, or stopping them once moving. The more massive the object (more inertia) the harder it is to start or stop. The Cadillac has more of a tendency to stay stationary (or continue moving), and resist a change in motion than a bicycle.

Answer:

L  = 6 * ( π + 1 )

Explanation:

The side of the equilateral triangle is  4, and each one of the circles is of radius 1. Then

Triangle vertex   A  B  and C

Trajectory of the belt, beginning in vertex A

1.-First circle  A  one turn

L₁  = 2*π*1   = 2*π

2.-Length between the circle A and B

L₂  = 2

3.- To wrap this circle we need to wrap the circle and to run the belt through the radius twice. The firs over the side AB and the second over the side BC, therefore

L₃ = 2*π*1 + 2*(1)

L₃ = 2*π + 2

4.-Length between two nearest points of circles B and C is 2 and length of the circle in C is 2*π*1. Then

L₄  = 2 + 2*π

Total length of the belt  is:

L  =  L₁ + L₂ + L₃ + L₄

L = 2*π + 2 + (2*π + 2 ) + ( 2 + 2*π )

L  = 6*π + 6

L  = 6 * ( π + 1 )

Answer:

The correct output will be "46.76 h.p.".

Explanation:

The given values are:

Gasoline's energy content,

= 46000 J/g

= 4.6 x10⁷ J/kg

Fuel usage,

= 13 kg/h

= [tex]\frac{13}{3600} \ kg/s[/tex]

Fuel efficiency,

= 21%

= 0.21

Now,

The average output will be:

= [tex](Energy \ content \ of \ gasoline)\times (fuel \ usage)\times (fuel \ efficiency)[/tex]

On substituting the values, we get

= [tex]4.6\times 10^7\times (\frac{13}{3600} )\times 0.21\times (\frac{1}{746}) h.p.[/tex]

= [tex]46.76 \ h.p.[/tex]

Answer:

the  average horsepower output of the engine is 46.76 hp

Explanation:

The computation of the  average horsepower output of the engine is shown below

The output of the engine is

= (Energy content of gasoline) × (usage of the fuel ) ×  (Fuel efficiency)

As we know that

1 hp = 746 W

where,

Energy content of gasoline = 46000 J / g = 4.6  × 107 J/kg

Usage of the fuel = 13 kg / h = 13 ÷ 3600 kg/s

Fuel efficiency = 21% = 0.21

Therefore, the output of the engine is

= 4.6 ×  107 × (13 ÷ 3600) × 0.21 × (1 ÷ 746) h.p.

= 46.76 h.p.

hence, the  average horsepower output of the engine is 46.76 hp

Answer:

The value is  [tex]L = 9.164 *10^{-5} \ H[/tex]

Explanation:

From the question we are told that

    The length of the solenoid is [tex]l = 30 \ cm = 0.3 \ m[/tex]

     The number of turns is  [tex]N = 250 \ turns[/tex]

    The cross-sectional  area is  [tex]A = 3.5 \ cm^2 = 3.5 *10^{-4} \ m^2[/tex]

Generally the self  inductance of the solenoid is  

       [tex]L = \frac{\mu_o * N^2 * A }{ l }[/tex]

Here  [tex]\mu_o[/tex] is the permeability of free space with value  [tex]\mu_o = 4\pi *10^{-7} \ T \cdot m/A[/tex]

So

       [tex]L = \frac{ 4 \pi*0^{-7} * 250^2 * 3.5 *10^{-4} }{ 0.3 }[/tex]

=>     [tex]L = 9.164 *10^{-5} \ H[/tex]

Answer:

PE = Fd

Explanation:

Potential energy is the energy possessed by a body by virtue of its position. It is expressed mathematically as:

PE = mgd

m is the mass

g is the acceleration due to gravity

d is the distance

Since Force F is expressed as the product of mass and acceleration due to gravity then, F = mg

Substitute into the formula above:

Recall that: PE = mgd

Since F = mg

PE = Fd

Hence the required expression is PE = Fd
