The ocean tides on earth are caused by both the moon's gravity and the sun's gravity. ... Even though the sun is much more massive and therefore has stronger overall gravity than the moon, the moon is closer to the earth so that its gravitational gradient is stronger than that of the sun.
The formula for solving voltage is V=IR where V represents the voltage, where "I" represent the current and R represents the resistance. Then, the given values are enumerated below and these will help us in solving for the unknown.
V=10 volts
I=?
R=2 ohms
V=IR
I=V/R
I=10/2
I=5 amperes
Therefore, the current is 5 amperes.
Answer:
(a). The value of angular speed of the merry-go-round 
= - 5.82 × 
(b). The linear speed of the girl after the rock is thrown V = -1.89 × 
Explanation:
Given data
Mass of the girl 
= 50.6 kg
Mass of merry-go-round 
= 827 kg
Radius r = 3.72 m
The speed of the rock relative to the ground 
= 7.82
(a). The angular speed of the merry-go-round is given by
![\omega = - [\frac{m_{r}v_{r} }{r} ] \frac{2}{m_{m} + 2m_{g} }](https://tex.z-dn.net/?f=%5Comega%20%3D%20-%20%5B%5Cfrac%7Bm_%7Br%7Dv_%7Br%7D%20%20%7D%7Br%7D%20%5D%20%5Cfrac%7B2%7D%7Bm_%7Bm%7D%20%2B%202m_%7Bg%7D%20%7D)
Put all the values in above formula
= - 5.82 ×
This is the value of angular speed of the merry-go-round.
(b). The liner speed of the girl is given by
⇒ V = r ×
⇒ V = - 3.72 × 5.82 ×
⇒ V = -1.89 ×
This is the linear speed of the girl after the rock is thrown.
<u>Answer:</u>
1. A graph is defined as <em>" A Diagram represents a system of connections or interrelations among two or more things by a number of different dots, lines etc".</em>
2. In simple words <em>"Graph is a representation of any object or a physical structure by dots, lines, etc.</em>
