The amount of heat required is B) 150 J
Explanation:
The amount of heat energy required to increase the temperature of a substance is given by the equation:

where:
m is the mass of the substance
C is the specific heat capacity of the substance
 is the change in temperature of the substance
 is the change in temperature of the substance
For the sample of copper in this problem, we have:
m = 25 g (mass)
C = 0.39 J/gºC (specific heat capacity of copper)
 (change in temperature)
 (change in temperature)
Substituting, we find:

So, the closest answer is B) 150 J.

To solve this problem we will apply the concepts related to the conservation of momentum. By definition we know that the initial moment must be equivalent to the final moment of the two objects therefore


Here,
 Mass of each object
 Mass of each object
 Initial velocity of each object
 Initial velocity of each object 
 = Final velocity of each object
= Final velocity of each object 
Since the initial velocity relative to the metal tank is at rest, that velocity will be zero. And considering that in the end, the speed of the two bodies is the same, the equation would become

Rearranging to find the velocity,

Replacing we have that,


Therefore the velocity of the shark immediately after it swallows the tank is
