The correct statements from the following list about how Uranus is different from Jupiter, and how its rings and moons formed and evolved includes the following:
- Uranus is much smaller and less massive than Jupiter.
- Uranus's appearance is nearly featureless; very bland.
- Uranus has some large moons and rings.
- Uranus rotates on its side, giving it extreme seasons. This may have been caused by an impact.
Describe Uranus?
Uranus is described as the seventh planet from the Sun. The name Uranus is a reference to the Greek god of the sky, Uranus, who, according to Greek mythology, was the great-grandfather of Ares, grandfather of Zeus and father of Cronus.
Some known facts about Uranus includes the following:
- Uranus is the coldest planet in the Solar System
- Uranus orbits the Sun on its side
- A Season on Uranus lasts one long day which is equal to 42 years
- Uranus is the second-least dense planet.

Archimedes found a piece of gold and a piece of silver with exactly the same mass. He dropped the gold into a bowl filled to the brim with water and measured the volume of water that spilled out. Then he did the same thing with the piece of solver. Although both metals had the same mass, the silver gad a larger volume; therefore, it displaced more water than the gold did. That's because the silver was less dense than gold. Afterwards he applied the same method to the crown for the king he served who had got a new crown from a jeweler who gave it to him. Archimedes found a piece of pure gold that had the same mass as the crown. He placed the pure gold chuck and the crown in water, one at a time. The crown displaced more water the piece of gold. Therefore, its density was less than pure gold.

Centripetal force is modeled by the equation:
F = MV^2/R
where
F = force
M = Mass
V = Velocity
R = Radius
I will assume the shark is swimming in a circle with a radius of 14 m / 2 = 7 m. The actual radius will be smaller, but I'll assume that the question is simply poorly worded. So we need to calculate the velocity of the shark. The circumference of the circle is pi*14m = 43.98229715 m. And since velocity is defined as distance over time, we have a velocity of 43.98229715 m / 80 s = 0.549778714 m/s.
Now substitute the known values into the equation for centripetal force.
F = MV^2/R
F = 681 kg * ( 0.549778714 m/s)^2 / 7m
F = 681 kg * 0.302256635 m^2/s^2 / 7m
F = 205.8367683 kg*m^2/s^2 / 7m
F = 29.40525261 kg*m/s^2
F = 29.40525261 N
Rounding to 2 significant figures gives a force of 29 Newtons.</span>
Answer:speed of slower cyclist is 5 mph
Explanation:
Given
Distance between two cyclist is 50 miles
One cycle is 4 times fast as other
Speed of slower cyclist is r miles per hour
speed of faster cyclist is 4 r
they meet after t=2 hr
Distance traveled by fast cyclist is 
Distance traveled by slower cyclist is 
speed of slower cyclist is 5 miles per hour
