Answer:
The strength of the gravitational force between two objects depends on two factors, mass and distance. the force of gravity the masses exert on each other. If one of the masses is doubled, the force of gravity between the objects is doubled. increases, the force of gravity decreases.
A periodic wave has a fixed pattern that is repeated. One completion of the wave pattern is called as cycle of the wave.
<u>Explanation:
</u>
Periodic waves are those which repeat the same kind of behaviour or pattern after a particular interval of time. So, completion of behaviour or pattern for a given time interval is termed as the cycle of wave.
Generally, one complete wave pattern makes a time interval of 2π. So each cycle will take nearly 2π time to form. The repetition of cycle in a time interval will help us to derive the frequency of the system.
With Uranus at an average distance of 2.88 billion kilometres from the Sun and Neptune at an average distance of 4.5 billion kilometres it would be very easy to point out which of the gas giants is the coldest, but if you were you were to say that Neptune was the coldest, you’d be wrong.<span>Given that we expect planets further from the Sun to be colder than those closer, this does make Neptune and Uranus quite a mysterious pair. Uranus and Neptune are brimming with volatiles such as water, methane and ammonia and due to their composition in comparison to Jupiter and Saturn, which are comprised mainly of hydrogen and helium, are labelled the ice giants. Scientists have measured how hot Uranus and Neptune should be and have found that Uranus is very cold and very dim</span>
Answer:
2v
Explanation:
The function of the velocity is:
v = v0 + a.t, where v is the top speed, v0 is the initial speed, a is the acceleration and t the time.
Both the tortoise and the hare start at rest, so v0 = 0. For the tortoise:
v = a.t
For the hare:
v' = a't', but a' = a and t' = 2t
v' = a*2t
v' = 2*at
v' = 2v
Answer:
2.0
Explanation:
i think 2.0 because u are trying find the magnitude of it
