which list is in order from smallest to biggest

Answer:

The correct option is (C).

Explanation:

Electric current can be direct or alternating.

The direct current flows only in one direction. It is unidirectional.

The alternating current or an C current reverse its direction periodically.

So, the correct statement regarding the alternating current is (c) i.e. Electrons reverse direction periodically.

The region of a longitudinal wave that is represented by an arrow is known as rarefaction. Thus, the correct option for this question is A.

A longitudinal wave may be defined as a type of wave where the displacement of the medium is in the same direction as the direction of the traveling wave. The distance between the centers of two consecutive regions of compression or the rarefaction is defined by wavelength, λ.

Longitudinal waves express areas of compression and rarefaction: compressions are regions of high pressure due to particles being close together. Rarefactions are regions of low pressure due to particles being spread further apart.

Therefore, the region of a longitudinal wave that is represented by an arrow is known as rarefaction. Thus, the correct option for this question is A.

Answer:

OPTION D (The waves will sometimes get very high and very low) is the answer.

Explanation:

Wavelength = velocity ÷ frequency

As the frequency which measures the number of waves per unit of time is inversely proportional to the wavelength, point X which lies between two sources, and one source is shorter than another, the wave heights at point x will vary as the distances from point X vary too. This means that waves at point X depending on the wave type and source will get very high at times and very low.

Answer:

2081.65 m

Explanation:

We'll begin by calculating the time taken for the load to get to the target. This can be obtained as follow:

Height (h) = 3000 m

Acceleration due to gravity (g) = 10 m/s²

Time (t) =?

h = ½gt²

3000 = ½ × 10 × t²

3000 = 5 × t²

Divide both side by 5

t² = 3000 / 5

t² = 600

Take the square root of both side

t = √600

t = 24.49 s

Finally, we shall determine the distance from the target at which the load should be released. This can be obtained as follow:

Horizontal velocity (u) = 85 m/s

Time (t) = 24.49 s

Horizontal distance (s) =?

s = ut

s = 85 × 24.49

s = 2081.65 m

Thus, the load should be released from 2081.65 m.

Answer:

Distance = 150 meters

Explanation:

Given the following data;

Work done = 6,000 Joules

Force = 40 Newton

To find the total distance covered by the wheelbarrow;

Workdone = force * distance

Substituting into the formula, we have;

6000 = 40 * distance

Distance = 6000/40

Distance = 150 meters

Therefore, the total distance the wheelbarrow was pushed is 150 meters.

Answer:

They rearrange themselves and join together differently to make new substances called products. The number of atoms of each type is the same before and after a reaction. This means that the total mass of the products is the same as the total mass of the starting substances. In other words, mass is conserved.

Answer:

Ben os ok. the moment of the bus and the worm are conserved

Explanation:

System formed by the bus and the worm, therefore the forces during the collision are internal and therefore the moment is conserved

initial instant. Airs of shock

        p₀ = My v₀

final instant. After the shock

        p_f = (M + m) v

the moment is preserved

        p₀ = p_f

        M v₀o = (M + m) v

       v = [tex]\frac{ M}{ M+m}[/tex]  v₀

       v = [tex]\frac{1}{1 +\frac{m}{M} }[/tex]  v₀

Let's analyze these equations the moment of the bus and the worm are conserved, therefore Ben is the one who is right. Let us propose the solution of the problem.

The person that I agree with based on their stance about the physics of the situation is; Ben Travlun

I will agree with Ben Travlun. The reason is that;

From the question, we see that the bug and the bus experience the same force, the same impulse, and the same momentum change.

Now, the concept of sameness above is not portrayed by Miles' statement because miles claims that the momentum change of the bug is much greater than the bus.

Now, though the bug has less mass and therefore more acceleration, the occupants of the very big bus will not feel the unusually small acceleration.

Finally, the bug is composed of a less strong material and as a result it will be scattered all over the windshield. However, this high level of the bug being scattered and the greater acceleration it possesses does not translate to greater force, impulse, or momentum change.

Answer:

2.6m

Explanation:

The formula for calculating the wavelength is expressed as;

λ = v/f

v is the velocity

f is the frequency of vibration

Given

f = 7.80Hz

We need to get the velocity

For string;

f = V/2L

7.80 = V/2(1.3)

7.80 = V/2.6

V = 2.6 * 7.8

V = 20.28m/s

Get the required wavelength

λ = v/f

λ = 20.28/7.80

λ = 2.6m

Hence  the wavelength of the first harmonic is 2.6m

Answer:

(B) 15 N.m

Explanation:

The deceleration of the wheel is first found by using the following formula:

[tex]\alpha = \frac{\omega_f - \omega_i}{t}[/tex]

where,

α = angular acceleration = ?

ωf = final angular speed = 0 rad/s

ωi = initial angular speed = 12 rad/s

t = time = 0.4 s

Therefore,

[tex]\alpha = \frac{0\ rad/s - 12\ rad/s}{0.4\ s}\\\\\alpha = -30\ rad/s^2[/tex]

here, the negative sign shows deceleration.

Now, we find the torque responsible for this deceleration:

[tex]\tau = I\alpha[/tex]

where,

τ = torque = ?

I = rotational inertia = 0.5 kg.m²

Therefore,

[tex]\tau = (0.5\ kg.m^2)(30\ rad/s^2)\\[/tex]

τ = 15 N.m

Therefore, the correct answer is:

(B) 15 N.m

a)      w = - [tex]\frac{m r }{I} v[/tex]  ,  b)   W = - ½ m_woman R² (1 + m_woman R / I²) v²

Explanation:

a) To solve this exercise, let's use the conservation of angular momentum.

We define a system formed by the table and the woman, therefore the torques are internal and the moment is conserved

initial instant. Before starting to move the woman

         L₀ = 0

final instant. After starting to move

         L_f = I w + m v r

the moment is preserved

        L₀ = L_f

         0 = Iw + m v r

         w = - [tex]\frac{m r }{I} v[/tex]                    (1)

the direction of the angular velocity is opposite to the direction of the linear velocity, that is, counterclockwise

b) for this part we use the relationship between work and kinetic energy

        W = ΔK

in this case the initial speed is zero and the final speed of the table, using the relationship between linear and angular variables

         v = w r

we substitute

          W = 0 - ½ I_total w²

          I_total = I + m_{woman} R²

          W = - ½ (I + m_woman R²)  ( [tex]\frac{m_{woman} R}{I} \ v[/tex]) ²

          W = - ½ (m_woman² R² + m_woman³ R³ / I²) v²

          W = - ½ m_woman R² (1 + m_woman R / I²) v²

Hope this helps you! Have a good day!

Answer:

Newton's second law states that the acceleration of an object is directly related to the net force and inversely related to its mass. ... So, the force/mass ratio (from the equation acceleration = force/mass) is the same for each. Therefore, the acceleration is the same and they reach the ground at the same time.

Example:Newton's Second Law of Motion says that acceleration (gaining speed) happens when a force acts on a mass (object). Riding your bicycle is a good example of this law of motion at work. Your bicycle is the mass. Your leg muscles pushing pushing on the pedals of your bicycle is the force.

Answer:

A) The time taken by the coin to reach the ground will be 0.4 seconds

B) Range of the motion of the coin will be 2m

Explanation:

This is a case of horizontal projectile motion as there's no initial vertical velocity given to the coin and has only horizontal velocity initially.

According to the equations of Horizontal projectile

Given :

Vertical distance to be traveled  ([tex]Sy[/tex])= 0.8m

Initial horizontal velocity ([tex]Vx[/tex])= 5m/s

For calculations, we will take acceleration due to gravity ([tex]g[/tex]) to be [tex]10 m/s^2[/tex]

A) Putting values in equation [tex]Sy=\frac{1}{2} *g*t^2[/tex]

   ⇒ [tex]0.8=\frac{1}{2} *10*t^2[/tex]

   ⇒[tex]\frac{1.6}{10} =t^2[/tex]

   ⇒ [tex]\sqrt{0.16} =t[/tex]

    ⇒  [tex]0.4=t[/tex]

Therefore, time taken by the coin to reach the ground is 0.4 seconds

B) Now using t= 0.4s putting values in equation [tex]Sx= Vx*t[/tex]

⇒[tex]Sx=5*0.4[/tex]

⇒[tex]Sx=2[/tex]

Hence , Range of the coin is 2m
