There is a large box and a small box on a table. The same force is applied to both boxes. The large box moves two feet and the s

mall box moves one foot. Which movement shows the most work done?
The movement of the large box shows more work because the box moved a longer distance.

The work done is equal because the same force was applied to both boxes.

The movement of the small box shows more work because the box moved a shorter distance.

The work done was equal because both boxes moved in the same direction as the force.

Explanation :

We know that the work done by an object depends directly on the applied force, displacement caused due to that force and on the angle between the force and the displacement.

Mathematically, it is written as :

W=Fdcos\theta

Where,

F is the applied force

d is the displacement or distance.

So, the work done is directly proportional to distance.

In this case, she same force is applied to both boxes. The large box moves two feet and the small box moves one foot.

So, the movement of the large box shows more work because the box moved a longer distance.

Hence, the correct option is (a).

A van moves with a constant speed of 100km/h. How far can it travel in 3 hours?
Molodets [167]

For this problem the formula you need is below.

Rate Time = Distance

What you're asking is what the rate of the car was, so to do that, we must plug! (Rate will be represented by “x”)

First, we need to find out how many hours is 2 hours and 24 minutes. If there are 60 minutes in an hour, then we can just say 24 minutes is 24/60 or 2/5 hours. So 2 hours and 24 minutes equals 2.4 hours. Now we plug:

2.4x = 200

Then we divide both sides by 2.4:

2.4x/2.4 = 200/2.4

x = 83.33 kilometers per hour. is the answer


Hope this helps!

Differentiate between Amplitude, wavelength and frequency in a Transverse wave.
s2008m [1.1K]
Two physical characteristics of a wave are amplitude and wavelength. The amplitude of a wave is the height of a wave as measured from the highest point on the wave (peak or crest) to the lowest point on the wave (trough). Wavelength refers to the length of a wave from one peak to the next.

A 75-kilogram hockey player is skating across the ice at a speed of 6.0 meters per second. What is the magnitude of the average
saveliy_v [14]

Answer:

(3) 690 N

Explanation:

Force: This is the product of mass and acceleration of a body. The S.I unit of force is Newton(N).

The formula for force is given as,

F = ma..................... Equation 1

Where F = force, m = mass, a = acceleration.

Also,

a = (v-u)/t................... Equation 2

Where v = Final velocity, u = initial velocity, t = time.

Given: u = 6.0 m/s, v = 0 m/s (bring to stop), t = 0.65 s.

Substitute into equation 2

a = (0-6)/0.65

a = -6/0.65

a = -9.23 m/s²

Also given: m = 75 kg

Substitute again into equation 1

F = 75(-9.23)

F = -692.25 N

The negative sign tells that the force oppose the motion of the player

F ≈ 690 N

Hence the right option is (3) 690 N

On the graph of voltage versus current, which line represents a 2.0 Ω resistor?​
Vikki [24]

Answer:

<h2>line B</h2>

Explanation:

According to ohm's law V = IR where;

V i sthe supply voltage (in volts)

I = supply current (in amperes)

R = resistance (in ohms)

In order to calculate the line that is equal to 2ohms, we need to calculate the slope of each line using the formula.

For line B, R = ΔV/ΔI

R = V₂-V₁/I₂-I₁

R = 14.0-4.0/7.0-2.0

R = 10.0/5.0

R = 2.0ohms

Since the slope of line B is equal to 2 ohms, this shows that the line B is the one that represents the 2ohms resistor.
