Answer: Its The Force Of Gravity
I hope this helps :)
The astrometric technique of planet detection works best for massive planets around nearby stars.
Hey there,
Your correct answer would be 30kg.
450 = m × 15 or also 450/15=m.
Hope this helps.

Answer:
The minimum speed required is 2.62m/s
Explanation:
The value of gravitational acceleration = g = 9.81 m/s^2
Radius of the vertical circle = R = 0.7 m
Given the mass of the pail of water = m
The speed at the highest point of the circle = V
The centripetal force will be needed must be more than the weight of the pail of water in order to not spill water.
Below is the calculation:




power out / power in so 230/420 = 0.547619048 using sigfiges its about .55 or 55%
