If we want to see our full image then the minimum size of the plane mirror:
(a) should be twice of our height.
(b) should be of our height
(c) should be half of our height
(d) depends upon our distance from mirror

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)]

Blank liquids and gases exert a buoyant force on objects placed in them

A2000 kg car is rounding a curve of radius 200 m on a level road. the maximum frictional force the road can exert on the tires of the car is 4000 n. what is the highest speed at which the car can round the curve?
