Answer:
5.63 gram
Explanation:
As per the equation
Q = Lm
where Q is the amount of heat needed to convert water in to vapour
and L is the latent heat f vaporization.
m is the mass converted, hence putting all the values.
m =Q/L
= 12725400/ 2260000
= 5.63 gram
Answer:
The frictional force acted on mass, m = 7.5 kg
Explanation:
Given data,
The acceleration of the box, a = 2 m/s²
The force acting on the box, F = 15 N
The mass of the box, m = ?
The force is defined as the product of mass and acceleration.
F = m x a newton
Therefore,
m = F / a
= 15 / 2
= 7.5 kg
Hence, the frictional force acted on mass, m = 7.5 kg
