In summary, the conversation discusses the magnitude of various forces and physical properties such as electric force, gravitational force, velocity of light, permitivity of vacuum, and density of a proton and the sun. The answers to the questions are all expressed in scientific notation and are of the same order, which may suggest a connection to Planck units. However, the question itself is questionable as it is based on arbitrary choices of objects and does not have a solid scientific basis.

I'm thinking Planck units here. But since your selection of proton and sun is purely arbitrary and the two aren't fundamentally related in any way, I could pick the density of any two objects and come up with the same ratio if I wanted to and ask the same question you're asking so I think your question is faulty

Q11. The number of fingers on my hands
(10)
Q12. The number of even primes (1)
(1)
Q13. Divide the 39th power of the eleventh answer by the 39th power of the twelfth answer.
(1039)
Q14. Why is the answer to Q13 the same order as the answers to Q7, Q8 & Q9?
A14. Because I ignored units in the ratio as did the OP in the answer to Q8.
 

FAQ: Answer this if you know your physics?

What is the difference between velocity and speed?

Velocity is a vector quantity that describes both the speed and direction of an object's motion. Speed, on the other hand, is a scalar quantity that only describes the magnitude of an object's motion.

How is acceleration calculated?

Acceleration is calculated by dividing the change in an object's velocity by the time it takes for that change to occur. Mathematically, it can be represented as a = (vf - vi) / t, where a is acceleration, vf is final velocity, vi is initial velocity, and t is time.

What is Newton's first law of motion?

Newton's first law of motion, also known as the law of inertia, states that an object at rest will remain at rest and an object in motion will continue to move in a straight line at a constant speed unless acted upon by an external force.

How does gravity affect objects?

Gravity is a force that attracts objects with mass towards each other. It affects objects by accelerating them towards the center of the Earth, causing them to fall towards the ground.

What is the difference between potential and kinetic energy?

Potential energy is the energy an object has due to its position or state. Kinetic energy is the energy an object has due to its motion. They are related in that potential energy can be converted into kinetic energy and vice versa.
