Solve the all parts of given question:
Question: A sports car of mass 1400kg (including the driver) crosses the rounded top of a hill (radius = 95m) at 27m/s.
Part I: Determine the normal force exerted by the road on the car.
(N)
Part II: Determine the normal force exerted by the car on the 79-kg driver.
Part III: Determine the car speed at which the normal force on the driver equals zero.
(m/s)
Please show all work to find the normal force exerted by the road on the car.
To listen to a radio station, a certain home receiver must pick up a signal of at least 1.0X10^-10 W.If the radio waves have a frequency of 93MHz, how many photons must the receiver absorb per second to get the station?
What is the magnitude of the electric force between a proton and an electron when they are at a distance of 1.91 angstrom from each other
One tire is inflated to a pressure of 40 and goes a distance of 18.0 ; the other is at 105 and goes a distance of 93.4. Assume that the net horizontal force is due to rolling friction only and take the free-fall acceleration to be = 9.80.
