Answer:
Correct answer: p₂ : p₁ = 1 : 3
Explanation:
A process that occurs at a constant temperature is called an isothermal process and the formula that applies to this process is:
p · V = const where p is pressure and V is volume
Given : V₂ = 3 V₁
p₁ V₁ = p₂ V₂ ⇒ p₂ / p₁ = V₁ / V₂ ⇒ p₂ / p₁ = V₁ / 3 V₁ ⇒ p₂ / p₁ = 1 / 3
p₂ : p₁ = 1 : 3
which means that when the volume is increased three times the pressure is reduced three times

Answer:
Work done = 13605.44
Explanation:
Data provided in the question:
For elongation of 2.1 cm (0.021 m) work done by the spring is 3.0 J
The relation between Energy (U) and the elongation (s) is given as:
U =
................(1)
where,
k is the spring constant
on substituting the valeus in the above equation, we get
3.0 = 
or
k = 13605.44 N/m
now
for the elongation x = 2.1 + 4.1 = 6.2 cm = 0.062 m
using the equation 1, we have
U = 
or
U = 26.149 J
Also,
Work done = change in energy
or
W = 26.149 - 3.0 = 23.149 J
Explanation:
Fgravity = G*(mass1*mass2)/D².
G is the gravitational constant, which has the same value throughout our universe.
D is the distance between the objects.
so, if you triple one of the masses, what does that do to our equation ?
Fgravitynew = G*(3*mass1*mass2)/D²
due to the commutative property of multiplication
Fgravitynew = 3* G*(mass1*mass2)/D² = 3* Fgravity
so, the right answer is 3×12 = 36 units.
