Answer:
4
Explanation:
G = Gravitational constant = 6.67 × 10⁻¹¹ m³/kgs²
= Mass of Earth
= Mass of Moon
r = Distance between Earth and Moon
Old gravitational force
New gravitational force
Dividing the equations
The ratio is
The new force would be 4 times the old force
Both forming images when placed in their respective places best describes Becquerel’s experiments.
<h3>What is Becquerel’s experiment?</h3>
This was conducted by Henri Becquerel in which he sought to know how uranium salts are affected by light.
He discovered that the salts emits a penetrating radiation and formed an image in the presence of light but didn't form any in darkness.

Answer:
An example would be
Explanation:
You have a ball with a mass of 10 kg swinging from a rope arond in a cirlce if we were to change the mass of the ball to 20 kg the kinetic energy would increase because we know the ball has more mass and more mass means ner force increases which is connected to kinetic energy. hope this answer helps!
Heat is most closely related to THERMAL energy.
Hi!
The linear velocity is given by:
v = ωR
And ω is given by: ω = 2π/T (where T is the time for 1 revolution)
Now, put these equations together:
v = 2πR/T
If it takes 5 seconds for 10 revolutions, then it takes 5/10 = 0.5 seconds for each revolution.
V = (2π * 2)/0.5
V = 4π/0.5
V = 8π rad/s
Then, we goes to the centripetal acceleration:
a = V²/R
a = 64π²/2
a = 32π² rad/s²
