Answer:
44.7 N
Explanation:
The gravitational force between the objects is given by:
where
G is the gravitational constant
m and M are the masses of the two objects
r is the distance between the centres of the two objects
In this problem, we have:
is the mass of the sphere
is the Earth's mass
is the Earth's radius, while h=310 km is the altitude of the sphere, so the distance of the sphere from Earth's centre is
Substituting into the equation, we find
We have that heat flow out of the copper sample is mathematically given as
Q=8.86809J
<h3> Heat flow</h3>Question Parameters
- A temperature of a 0.349 kg sample of copper
- decreases from 87.0 °C to 21.0 °C.
Endothermic Reaction
It is common knowledge that an endothermic reaction is one where the system absorbs heat energy from the <em>environs</em>.
Exothermic Reaction
An exothermic reaction is one where the system releases heat energy to the <em>environs</em>.
Generally the equation for Heat is mathematically given as
Q=8.86809J
