Answer:
F = 313.6 N
Explanation:
weight is the force acting on an object due to gravity.
so,
- f = ma (m = mass, a = acceleration)
- f = 32 × 9.8
- f = 313.6 Newton
( note : i have taken acceleration due to gravity as 9.8, it can be taken as an approx of 10, so if you have to take 10, the weight of girl will be 320 Newton )

The amount of heat needed to increase the temperature of a substance by

is given by

where
m is the mass of the substance

is its specific heat capacity

is the increase of temperature
The sample of silver of our problem has a mass of

. Its specific heat capacity is

and the increase in temperature is

Therefore, the amount of heat needed is
