Answer:
From -15⁰ to 0⁰
H=mc¶ 
where H= heat absorbed or evolved
m=mass involved
c=specific heat capacity
¶=change in temperature

Answer:
7 m/s^2
Explanation:
Given that the jet is traveling 37.6 m/s when the pilot receives the message. 
And it takes the pilot 5.37 s to bring the plane to a halt.
Acceleration of the plane can be calculated by using first equation of motion 
V = U - at
Since the plane is going to stop, the final velocity V = zero. 
And the acceleration will be negative 
Substitute all the parameters into the formula 
0 = 37.6 - 5.37a
5.37a = 37.6
Make a the subject of formula 
a = 37.6 / 5.37
a = 7.0 m/s^2
Therefore, the acceleration of the plane to bring the plane to a halt is 7 m/s^2
 
        
             
        
        
        
Answer:

Explanation:
At thermal equilibrium we have heat given by aluminium must be equal to the heat absorbed by the water
so we will have


so we will have

so we have

so we have
