What is the area of a wing (sq. ft) that has an aspect ration of 7:1 and a wing span of 40 feet?

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)]

If vx = 7.00 units and vy = -7.60 units, determine the magnitude of v⃗ . determine the direction of v⃗ .

Acoil suspended freely, points in some direction when no current is passed through it . can you tell what will happen when a current is passed though it?
