The amount of heat will be equal to Lm.
Where L is the latent heat of fusion and m is mass of the ice.
Latent heat of ice = 80cal/g.
So the amount of heat required here will be 35× 80cal
= 2,800 cal.
you can find it using the equation: potential energy=mass*gravitational acceleration*height.
energy=50kg*9.8N/kg*40m=19600Nm=19600J or 19.6kJ
Sometimes they use 10 instead of 9.8 for the g constant.

Answer:
18.4 s
Explanation:
The time constant of an RC circuit is given by
where
R is the resistance
C is the capacitance
For the first circuit we have
So we can find the capacitance
Now in the second circuit, the new resistance is
So the new time constant will be
The answer to your question is the Origin
