Given that an electron revolves in a circle and the essential centripetal force is given as
now we need to find its speed
so we know that this force is given as
#8
Here the force due to earth on satellite is the centripetal force to revolve around earth
so we can say that force due to earth is given as
we know that
now from above equation we have
Answer:Let’s assume that, after the soccer ball is kicked and moves through its trajectory, it first makes contact with level ground a horizontal distance of 35 meters from where it was kicked. Let’s also assume that we can neglect air resistance. The time, t, that the soccer ball is in the air until it first contacts the ground can be found from the equation h = (1/2)gt^2 which can be rewritten as t = sqrt(2h/g) where h is the vertical distance the ball falls which is the height of the hill since the ball was kicked horizontally, and g is the acceleration of gravity which is 9.8 m/s^2. So t = sqrt(2(22)/9.8) = 2.12 seconds. In that time, the ball travelled 35 meters so its horizontal velocity was 35 meters/2.12 seconds = 16.5 meters/second.

Answer:
F=523712 N
Explanation:
density=mass/volume
and shape is cubic so
volume=(4)^3
volume=64 m^3
mass=835*64
mass=53440 Kg
Hydrostatic force=53440*9.8=523712 N
Answer:
Cycles of matter are called biogeochemical cycles because they include both biotic and abiotic components and processes. Components that hold matter for short periods of time are called exchange pools, and components that hold matter for long periods of time are called reservoirs
