Answer:
Part a)
Part b)
So this speed is independent of the mass of the rider
Explanation:
Part a)
By force equation on the rider at the position of the hump we can say
now we will have
now we have
Part b)
At the top of the loop if the minimum speed is required so that it remains in contact so we will have
at minimum speed
So this speed is independent of the mass of the rider
Answer:
girl what- I can't answer this but I need points so I'ma just put this random lol sorry tho . ask the tutor
Answer:
Infinite distance; all objects in the universe.
Explanation:
In physics, there are four fundamental interactions, and the fundamental interactions include strong force, electromagnetic force, weak force and gravitational force. These forces governs how objects or particles interact and how certain particles decay.
With respect to their relative strengths, the strong force is regarded as the most powerful, followed by the electromagnetic force, the weak force, and the gravitational force.
Gravitational force and electromagnetic force operates at infinite distance. Gravitational force acts between all objects of the universe, no matter the distance/how far the body are apart.
Answer:
B cus is in the south but that pfp tho
A) It is very dry at the equator because it is so hot.
False. It depends on what else is around.
The Sahara Desert is near the Equator.
But so is the Amazon rain forest.
B) Higher places are usually warmer because they are closer to the Sun.
False. Higher places are usually colder, because the air is thinner.
C) Land masses change the direction of currents.
True
D)The sun provides energy needed for the evaporation process. Gravity allows water droplets to fall as precipitation.
True
