Planet Y has rotated by 135.5° through during this time.
To find the answer, we need to know about the relation between angle and radius of orbit.
<h3>What's the expression of angle in terms of radius?</h3>
- Angle= arc/radius
- As arc = orbital velocity × time,
angle= (orbital velocity × time)/radius
- Orbital velocity= √(GM/radius), G= gravitational constant and M = mass of sun
- So, angle = (√(GM)× time)/radius^3/2
<h3>What's is the angle rotated by planet Y after 5 years, if ratio of the radius of orbit of planet X and Y is 4:3 and planet X is rotated by 88°?</h3>
- Let Ф₁= angle rotated by planet Y, Ф₂= angle rotated by planet X
- As time = 5 years ( a constant)
- Ф₁/Ф₂= (radius of planet X / radius of planet Y)^(3/2)
- Ф₁= (radius of planet X / radius of planet Y)^(3/2) × Ф₂
= (4/3)^(3/2) × 88°
= 135.5°
Thus, we can conclude that Planet Y has rotated by 135.5° through during this time.

Answer:
liquid.
Explanation:
That is almost the definition of a liquid. So the answer is a liquid.
Answer:
786 J
Explanation:
Let g = 9.81 m/s2. The vertical distance that the canon ball must have traveled within 1.65 s is (ignoring air resistance):
So the work done by gravity would be the product of gravity force and the distance it traveled
[tex]E_p = Ph = mgh = 6*9.81*13.35 = 786 J
Harper used the the frequency principle (F) by planning to work out 4-5 days a week. Frequency is how often you exercise, usually on a weekly basis.
She used the intensity principle (I) by deciding to exercise on a moderate level, rather than, for example, an intense workout. Intensity is basically how hard you exercise and push yourself.
She then used the time (T) principle by choosing to workout for 60 mins per day. Time meaning how much time you spend working out each day.
And lastly, she used the type (T) principle by devising a specific type and/or set of exercise(s) to do, which in her case, is drills, jogging, and weight lifting.
So all in all, Harpers frequency is 4-5 days per week, her intensity is moderate, her time is 60 mins/day, and type is basketball drills, jogging and weight lifting.
Hope I helped! :)

A vacuum doesn't contain a medium.
Light, which is an electromagnetic
wave and doesn't require a medium,
will travel there. Sound, which is a
mechanical wave and requires a
medium, will not travel there.</span>
(You can see the light of the sun and other stars, which travels to us through
space. Astronauts can't hear the sound of each others' voices when they're
standing together on the moon because there's no medium between them,
so they have to use radio even to go only a few feet.)
