Answer:
-2.66 kJ
Explanation:
At constant pressure, work done is:
W = -P ΔV
W = -(95.000 Pa) (43 m² − 15 m²)
W = -2660 J
W = -2.66 kJ
A few of the positive particles aimed at a gold foil seemed to bounce back off of the thin metallic foil. so, the correct answer is option A.
<h3>What is the Rutherford experiment?</h3>
Rutherford performed an experiment in which alpha particles are bombarded on the gold foil.
Some of the particles bounced back which indicates that there are heavy particles present in the center of an atom.
Most alpha particles pass through the atom which indicates that there is a lot of empty space in an atom.
A few of the positive particles aimed at a gold foil seemed to bounce back off of the thin metallic foil. so, the correct answer is option A.

Between both solid and gases, should be liquid.
The answer is C, an educated guess
Answer:
r = 2.55 m
Explanation:
Given that,
First charge, q₁ = 32.2 μC
Second charge, q₂ = + 12.3 μC
The force between charges, F = 0.544 N
We need to find the distance between charges. The force between two charges is given by the formula as follows :
So, the charges are 2.55 m apart.
