Answer: It's the third one.
Explanation:
Answer:

Explanation:
Newton's law of cooling
Rate of cooling

Where To is the surrounding temperature
T is object temperature at any time t
now by removing proportionality sign

Now by separating variables


So

Where C is constant

C' is also a constant and it can be find by using boundary conditions.

<span>1 w = 1N/s the change in total energy =mgh = 600*4 = 2400N. 2400N/200N/s = 12seconds
</span>
Answer:
A
Explanation:
Initial gravitational energy = final kinetic energy + heat
mgh = KE + Q
(50 kg) (9.81 m/s²) h = 78400 J + 884000 J
h = 1960 meters
