What does a star color tell you about the amount of energy it emits?

Acar of mass m goes around a banked curve of radius r with speed v. if the road is frictionless due to ice, the car can still negotiate the curve if the horizontal component of the normal force on the car from the road is equal in magnitude to 101) a) mv2/r b) mg/2. d) mg e) tan[v2/(eg)]

In order for the bug to fly through the air a force has to push the bug forward. identify this force. how does the bug produce
