Entropy is the measure of the amount of disordered in a system.

<u>Explanation:</u>

In 1850, Entropy introduction by the German physicist Rudolf Clausius refers a measurement of the system's thermal energy in unit temperature. It is not for useful work because the work originates from ordered molecular motions. And, this also measures the molecular disturbance or randomness of the system.

The concept behind this provides deep view into spontaneous changes in many everyday phenomena’s. The idea of entropy is a mathematical way of coding an intuitive idea whose processes are impossible, and not violate the basic principle of energy conservation.

Answer:

The gravitational force between these two objects is around $F_{g}=6.674*10^{-11} N$

Explanation:

The gravitational force can be written as:

$F_{g}=G\frac{m_{1}m_{2}}{r^{2}}$

Here:

G is the gravitational constant $G = 6.674*10^{-11} m^{3}kg^{-1}s^{-2}$
m(1) is the first mass
m(2) is the second mass
r is the distance between two bodies.

If we see, the gravitational constant is a very small number, therefore the gravitational force is representative just when we have to massive bodies. Let's suppose that the mass of the pencil is 0.1 kg and the eraser is 0.1 kg too, the distance between them would be around 10 cm or 0.1 m, for instance.

Now let's calculate the gravitational force of these two bodies.

$F_{g}=G\frac{0.01*0.01}{0.1^{2}}$

$F_{g}=6.674*10^{-11} N$

As we see it is very small force, so it is negligible relation to the earth gravitational force. That is why these two objects do not move towards each other.

I hope it helps you!

Different forces were applied to five balls, and each force was applied for the same amount of time. The data is in the table. A

Annette [7]

The magnitude of impulse on Ball A will become twice (doubles). Hence, option (c) is correct.

Impulse:

The effect of applied force acting for a very small interval of time is known as Impulse.

Given data:

The initial magnitude of the force on Ball A is, F = 50 N.

The time interval for the applied force on Ball A is, t = 1.25 s.

And the impulse at initial on ball A is, I = 62.5 N-s.

Now, if force on ball A doubles, which means new magnitude of force is,

F' = 2F

F' = 2 × 50

F' = 100 N

For same time interval, the new impulse on Ball A is given as,

I' = F' × t

Solving as,

I' = 100 × 1.25

I' = 125 N-s

Taking the ratio of both the impulses as,

I' / I = 125/62.5

I' = 2 I

Thus, we can conclude that the magnitude of impulse on Ball A will become twice (doubles). Hence, option (c) is correct.

Car A has twice the mass of Car B; both travel at the same speed. Compared to Car B. Car A has:

krek1111 [17]

Answer:

Car A has twice the energy of car B.

Explanation:

The kinetic energy of an object is given by :

$K=\dfrac{1}{2}mv^2$

Where

m is the mass

v is the speed of the object

Car A has twice the mass of Car B. Both travel at the same speed i.e.

$m_A=2m_B$

So,

$\dfrac{K_A}{K_B}=\dfrac{(1/2)m_Av^2}{(1/2)m_Bv^2}\\\\=\dfrac{2m_B}{m_B}\\\\\dfrac{K_A}{K_B}=2\\\\K_A=2\times K_B$

So, the kinetic energy of car A is twice of the kinetic energy of car B.
