Answer : The amount of heat needed is, 1188 J
Explanation :
Formula used :
where,
q = heat needed = ?
m = mass of copper = 55 g
c = specific heat capacity of copper = 
= initial temperature = 
= final temperature = 
Now put all the given values in the above formula, we get:
Thus, the amount of heat needed is, 1188 J
To determine the velocity of an object, you need to know the displacement and the change in time.
v = displacement / change in time
No because the light can only produce the color the manufacturer gave it and it is thin air unless the laser beam was able to make things on fire then the substance would be called a gas
