Of the gravitational pull and other things like mass. Planet earth it,s self as you said sir.
The linear speed of the ladybug is 4.1 m/s
Explanation:
First of all, we need to find the angular speed of the lady bug. This is given by:
![\omega=\frac{2\pi}{T}](https://tex.z-dn.net/?f=%5Comega%3D%5Cfrac%7B2%5Cpi%7D%7BT%7D)
where
T is the period of revolution
The period of revolution is the time taken by the ladybug to complete one revolution: in this case, since it does 1 revolution every second, the period is 1 second:
T = 1 s
Therefore, the angular speed is
![\omega=\frac{2\pi}{1 s}=6.28 rad/s](https://tex.z-dn.net/?f=%5Comega%3D%5Cfrac%7B2%5Cpi%7D%7B1%20s%7D%3D6.28%20rad%2Fs)
Now we can find the linear speed of the ladybug, which is given by
![v=\omega r](https://tex.z-dn.net/?f=v%3D%5Comega%20r)
where:
is the angular speed
r = 65.0 cm = 0.65 m is the distance of the ladybug from the axis of rotation
Substituting, we find
![v=(6.28)(0.65)=4.1 m/s](https://tex.z-dn.net/?f=v%3D%286.28%29%280.65%29%3D4.1%20m%2Fs)

Answer:
165.529454
Explanation:
According to the Pythagorean Theorem for calculating the lengths of a right angle triangle's sides, a^2 + b+2 = c^2, where c is the longest side (and the side opposing the right angle). So in your case it would be 150*150 + 70*70 = 27400. And √ 27400 is your answer.
C. Forces have mass and take up space
