To solve this problem we will apply the concepts related to the thermal efficiency given in an engine of the Carnot cycle. Here we know that efficiency is given under the equation
Where,
Temperature of Cold Body
Temperature of Hot Body
= Efficiency
According to the statement our values are:
Replacing we have that
Therefore the temperature of the heat source is 300K
The force of gravity between two objects is given by:
where
G is the gravitational constant
m1 and m2 are the masses of the two objects
r is their separation
In this problem, the mass of the object is
, while the Earth's mass is
. Their separation is
, therefore the gravitational force exerted on the object is

Answer:
250 cm³
Explanation:
given,
Length of the Box, L = 5 cm
Width of Box, W = 5 cm
height of the box, H = 10 cm
Volume of the Box = L W H
V = 5 x 5 x 10
V = 250 cm³
Volume of the box is equal to 250 cm³
