Answer:
the average kinetic energy of water particles - C.
Venus has the slowest rotation rate.
It takes Venus 243.7 Earth days to rotate once.
Planet Period
Venus 243.7 (Earth) days
Mercury 58.8 days
Pluto 6.4 days
Mars 24.6 hours
Earth 23.9 hours
Uranus 17.2 hours
Neptune 16.1 hours
Saturn 10.7 hours
Jupiter 9.9 hours
Interesting . . . the largest planet rotates the fastest.
I wonder why that is.
Hi,
My best answer would be Gravity. Is it a multiple choice question? Or is it an essay question.
Energy at top = U = mgh = 40 * 9.8 * 12 = 4704 J
Energy at bottom = 1/2 mv² = 1/2 * 40 * 10² = 4000 / 2 = 2000 J
Energy Lost = Final - Initial = 4704 - 2000 = 2704 J
In short, Your Answer would be Option D
Hope this helps!
Answer:
A)
B)
Explanation:
= diameter of the spherical chamber = 5.50 m
Volume of the spherical chamber is given as
= density of the seawater = 1025 kg m⁻³
Part A)
Force of buoyancy by seawater on the chamber is given as
Part B)
= tension force in the cable in upward direction
= mass of the chamber = 87600 kg
Weight of the chamber is given as
Using equilibrium of force in the vertical direction, we have
