Part 1
If water does not spill at the top point of the circular motion then for the minimum speed condition we can say normal force will be zero at the top position



given that
R = 1 m
g = 9.8 m/s^2
now from above equation we have

Part b)
for minimum value of angular speed we will have



Kinetic energy because the horse is in motion
Answer:
D) Grounding
Explanation:
The potential difference between cloud and ground leads to ionization of the atmosphere and resulting conduction through the air often to ground (although it can be between clouds at different potentials. I would say grounding, like the spark when you touch a hot battery terminal to ground on a car.
Answer:
2 Newtons
Explanation:

Therefore, your mass would be 1kg and your acceleration would be 2m/s/s
Plug the numbers into the equation:

which will equal
