A Ferris wheel has diameter of 10 m and makes one revolution in 8.0 seconds. A person weighing 670 N is sitting on one of the benches attached at the rim of the wheel. What is the apparent weight (that is, the normal force exerted on her by the bench) of the person as she passes through the highest point of her motion?

1082.8N

Explanation:

at the highest point,

Ft= Fc+Fw

Ft:total force or apparent weight

Fc: centripetal force

Fw: weight of person

Ft= mv²/r + Fw

v=ωr

v= 2πfr

v= 2π(1/8)10

v= 7.85m/s

Ft= mv²/r + Fw               m=Fw/g=670/10=67kg

Ft= (67)(7.85)²/10+670

Ft= 1082.8N

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.
