In the heat equation, what does c represent
2 answers:
Answer : 'c' represent the 'Specific heat of substance'.
Explanation :
Specific heat : It is defined as the amount of heat required to raise the temperature of 1 kilogram of substance by one degree Celsius. The S.I unit of specific heat is, Joule per kelvin (J/K).
Formula for specific heat,
where,
c = specific heat capacity of substance
Q = heat required
m = mass of substance
= change in temperature
Hence, 'c' represent the 'Specific heat of substance'.

An object moving with constant speed can be accelerated if direction of motion changes. For example, an object moving with a constant speed in a circular path has an acceleration because its direction of motion changes continuously.

Solution :
Given :
Mass attached to the spring = 4 kg
Mass dropped = 6 kg
Force constant = 100 N/m
Initial amplitude = 2 m
Therefore,
a).
= 10 m/s
Final velocity, v at equilibrium position, v = 5 m/s
Now,
A' = amplitude = 1.4142 m
b).
m' = 2m
Hence,
c).
Therefore, factor
Thus, the energy will change half times as the result of the collision.
