Kepler found that the orbits of the planets flowed three laws (rayed disk),(black dot) and maybe (symbols) hopes this helps out for you
We can solve the problem by using Netwon's third law:
where:
T is the orbital period of the planet
R is the average radius of the orbit (so, the average distance of the planet from the star)
M is the mass of the star.
First, we need to convert the period and the radius into SI units:
And then, re-arranging the formula and substituting the numbers we find
Answer: 218,240,000 fathom.
Explanation:
Given : A fathom is a unit of length, usually reserved for measuring the depth of water.
A fathom is approximately 6 ft in length.
The distance from Earth to the Moon to be 248,000 miles.
Since, 1 mile =5280 feet
Then, the distance from Earth to the Moon =
The distance from Earth to the Moon in fathoms :
Hence, the the distance in fathoms 218,240,000 fathom.
Answer:
Explanation:
Time can be found by dividing the distance by the speed.
The distance is 45 meters and the speed is 12.5 meters per second.
Divide. Note that the meters, or "m" will cancel each other out.
It will take the dolphin 3.6 seconds to swim a distance of 45 meters are 12.5 meters per second.
Answer:
a)
b)
c) Therefore it is a nonconservative force
Explanation:
Distance traveled in one complete circular trip against friction
The force of friction is
The work of friction is the force of friction in the distance so
a).
b).
c).
Since the circle returns to its initial position in both cases and the work done by the friction force different in both cases, so the friction force does depend on the path;
