Answer:
Explanation:
First, we are going to calculate the electrical potential in the point middle between the two charges
Remember that the electrical potential can be calculated as:
Where
and it is satisfy the superposition principle, thus
The electrical potential at 10 cm from charge 1 is:
Since the work - energy theorem, we have:
where q is the electron's charge and m is the electron's mass
Therefore:
We have that heat flow out of the copper sample is mathematically given as
Q=8.86809J
<h3> Heat flow</h3>Question Parameters
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

Answer:
Explanation:
Assuming the crate does not lift above the ground and remains along the floor, then its acceleration will be in the horizontal direction. Therefore, we can use Newton's second law to find its acceleration:
where
is the net force on the crate along the x-direction
m is the mass of the crate
is the acceleration
Here we have:
m = 50.0 kg
is the component of the pulling force along the horizontal direction
Solving for the acceleration,
