Answer:
The time-interval of the collision is
Explanation:
As given the force is equal to the rate of change of momentum. Mathemticaly this is:
We can rearrange this equation to solve for which gives
which is our answer.
In words this means the time interval is equal to the momentum change in that interval divided by the force applied that caused this momentum change.
For a simple pendulum, the mathematical equation that describes the period (T) is T=√(l/g) where l is the length of the string and g is the acceleration due to gravity (9.81 metres per second). Therefore it can be seen that both gravity and the length of the string within a pendulum effects its period.
I did not see the post. But if she actually needs help She can dm me. keep y'all's head up❤
Answer:
Explanation:
Torque due to applied force along its surface is given as
here we know that
r = radius of earth =
Now we have
now we know that
initial angular speed of Earth is
final angular speed will be
so now we have
here we have moment of inertia of Earth is given as
now we have

Answer:</h2>
<h2>_____________________________________</h2><h3>ENDOTHERMIC REACTIONS:</h3>
Endothermic Reaction are those reactions in which the reactants absorb the energy from their surrounding and forms the product.
<h2>_____________________________________</h2><h3>How to know endothermic reaction?</h3>
Those changes in which a substance goes from More-ordered state to less-oredered state are endothermic. Where they change from less ordered to more ordered is exothermic.
More ordered means that the movement of vibration of the particles of the substance is less and the are more close to each other. More to less ordered state is given as,
Solid>Liquid>Gas.
<h2>_____________________________________</h2><h2>Question:</h2>
In the question it asks about the melting of the ice cube. Ice cube is a solid, and when it will melt, it will change into the liquid water. As we know that, Solid is more ordered and Liquid is less ordered, and The change from more-ordered to less-ordered is endothermic thus the answer is ENDOTHERMIC.
