Answer:
C 0.85 j/g*k
Explanation:
The specific heat capacity of a material is given by:

where
Q is the amount of heat supplied to the object
m is the mass of the object
is the increase in temperature of the object
For the object in this problem, we have
m = 117 g is the mass
Q = 1200 J is the heat supplied
is the increase in temperature
Substituting into the formula, we find the specific heat:

Answer:
The value is 
Explanation:
From the question we are told that
The height is 
The time taken is
From the equation of motion we have that

Here u = 0 because the rocket started at rest

=> 
=> 
Also from the kinematic equation we have that

=> 
=>
