It could be warmer solid, or liquid, or gas, depending on the pressure and the amount of heat added.
Specific heat
Let me know if you need further explanation!
Answer:
Explanation:
a. WEIGHT: As we have seen, weight is the gravitational force exerted on an object by the Earth (or any other celestial body). If an object is near the Earth's surface and has mass, then the object has a weight. The magnitude of its weight is w = mg and its direction is toward the center of the Earth.
Explanation:
It is given that,
Angular frequency, 
Maximum displacement, A = 0.5 m at t = 0 s
We need to find the time at which it reaches its maximum speed. Firstly, we will find the maximum velocity of the object that is exhibiting SHM.


............(1)
Acceleration of the object, 

...............(2)
Using first equation of motion we can calculate the time taken to reach maximum speed.



t = 0.25 s
So, the object will take 0.25 seconds to reach its maximum speed. Hence, this is the required solution.
