Answer:

The first law of thermodynamics

Explanation:

states that energy is always conserved, it cannot be created or destroyed. In essence, energy can be converted from one form into another.

A mass m is attached to an ideal massless spring with spring constant k. In experiment 1 the mass oscillates with amplitude a, a
Trava [24]

Time period remains the same in both the experiment as change in amplitude does not affect time period.

What are the factors on which time period depends in SHM?

Time period is given by:

T=2\pi \sqrt{\frac{m}{k} }

where,

T = time period

m = mass

k = spring constant

In a straightforward harmonic motion, we see from the preceding formula that the time period depends only on the object's mass and spring constant (SHM). The time period will adjust to any variations in the object's mass or the spring constant.

What is Spring Constant?

A spring's "spring constant" is a property that quantifies the relationship between the force acting on the spring and the displacement it produces. In other words, it characterises a spring's stiffness and the extent of its range of motion.

A solid metal ball and a hollow plastic ball of the same external radius are released from rest in a large vacuum chamber. When
S_A_V [24]

Answer:

time of fall and the final velocity

Explanation:

the mass of solid ball is more than the mass of hollow ball.

According to the third equation of motion

v² = u² + 2gh

As the final velocity v does not depend on the mass of the object, so the final velocity of both the ball is same.

According to the first equation of motion

v = u + gt

As v is same for both the balls, the time is also same for both the balls.

So, they both have same time of fall and final velocity.

A measure of the disorder of a system is called:<br> enthalpy<br> energy<br> entropy<br> synergy
Gre4nikov [31]

The answer is Entropy or part C.


Entropy is basically a thermodynamic quantity that tells the randomness of a system or as said in the question tells us a measure of the disorder of the system.


The second law of thermodynamics states that a closed system has entropy which may remain constant or otherwise might increase.


It is basically the measure of the change of a system or universe when it goes from order to disorder.
