Answer:
(A) The period of its rotation is 0.5 s (2) The frequency of its rotation is 2 Hz.
Explanation:
Given that,
a ball is spun around in circular motion such that it completes 50 rotations in 25 s.
(1). Let T be the period of its rotation. It can be calculated as follows :

(2). Let f be the frequency of its rotation. It can be defined as the number of rotations per unit time. So,

Hence, this is the required solution.
Yes, It has a stored energy in that stone.
Answer:
Separation of the Earth into layers (crust, mantle, inner core, and outer core) was largely caused by gravitational differentiation (separating different constituents at temperature where materials are liquid or plastic, owing to differences in density) early in Earth's history.

Answer:
<em>The answer to your question is </em><em>more force</em>
Explanation:
<em>A consequence of more mass having more inertia is that more force is required to bring the helicopter to the same speed as the bullet </em>

The temperature of the oxygen gas is 243.75 K.
Using ideal gas law to explain the answer, the absolute temperature of the gas will decrease if the number of moles of the gas increases and it will increase if the volume and/or pressure of the gas increases.
The reaction of the given elements;

volume of the collected oxygen gas, V = 10 L
pressure of the gas, P = 1 atm
number of moles of the gas, n = 0.5
Using ideal law the temperature of the oxygen gas is calculated as follows;

Thus, the temperature of the gas is 243.75 K.
Using ideal gas law to explain the answer. The absolute temperature of the oxygen gas is directly proportional to the product of its pressure and volume and inversely proportional to its number of moles. That is the absolute temperature of the gas will decrease if the number of moles of the gas increases and it will increase if the volume and/or pressure increases.
