(a) Intensity obeys inverse square law from basis of light passing through a given surface.

(b) Gravitation obeys inverse square law from the basis of force between two masses.

(c) The maximum magnitude of the acceleration of the block is 126.75 m/s².

<h3>What is intensity?</h3>

Intensity is the ratio is ratio of power to area of a given surface.

I = P/A (W/m²)

where;

  • P is power
  • A is area
<h3>Universal gravitation law</h3>

F = \frac{Gm_1m_2}{r^2}

Intensity and gravitation do not obey inverse square law for same reason;

  • Intensity obeys inverse square law from basis of light passing through a given surface.
  • Gravitation obeys inverse square law from the basis of force between two masses.
<h3>Acceleration of the block</h3>

a = v²/A

a = (3.9²)/0.12

a = 126.75 m/s²

If at 10m above the ground an object has 50J of Kinetic Energy, with 50J of Potential Energy. How high can the object travel?
steposvetlana [31]

Hi there!

\large\boxed{\text{B) 20 meters}}

We know that:

E_T = U + K

U = Potential Energy (J)

K = Kinetic Energy (J)

E = Total Energy (J)

At 10m, the total amount of energy is equivalent to:

U + K = 50 + 50 = 100 J

To find the highest point the object can travel, K = 0 J and U is at a maximum of 100 J, so:

100J = mgh

We know at 10m U = 50J, so we can solve for mass. Let g = 10 m/s².

50J = 10(10)m

m = 1/2 kg

Now, solve for height given that E = 100 J:

100J = 1/2(10)h

100J = 5h

<u>h = 20 meters</u>

In a lab experiment, two identical gliders on an air track are held together by a piece of string, compressing a spring between
ddd [48]

Answer:

Part a)

v_2 = -0.300

Part b)

Here final kinetic energy is more than the initial kinetic energy

This increase in kinetic energy is due to spring connected between them as the spring energy is converted into kinetic energy of two blocks

Explanation:

Part a)

As we know that there is no external force on the system of two gliders

So here we can use momentum conservation for two gliders

So we will have

m_1 v_1 + m_2 v_2 = (m_1 + m_2)v_i

m_1 = m_2

1.300 + v_2 = 2(0.500)

v_2 = -0.300

Part b)

now we will have

initial kinetic energy of both gliders is given as

K_i = \frac{1}{2}(m + m)(0.500)^2

K_i = 0.25m

Final kinetic energy of two gliders

K_f = \frac{1}{2}m(0.300)^2 + \frac{1}{2}m(1.300)^2

K_f = 0.89 m

so here final kinetic energy is more than the initial kinetic energy

This increase in kinetic energy is due to spring connected between them as the spring energy is converted into kinetic energy of two blocks
