If the light has all visible colors in it, and the object
reflects them all, then the object appears white.
Answer:
Explanation:
Since the surface is frictionless therefore there will be no friction force on block but there will be weight of block which we can divide in to two components i.e. mgcosθ &mgsinθ which is perpendicular and parallel to the surface respectively.
In response to mgcosθ ramp will apply a normal force to the block which will be of equal magnitude to that of mgcosθ.
Therefore Ramp will apply a Force of mgcosθ on block where m is the mass of block.
Answer:
58230.08849 Pa
Explanation:
F = W = Weight of the person = 658 N
A = Area to which the force is applied =
When the force is divided by the area to which the force is applied we obtain the pressure
Hence, pressure the foot exerts on the floor is 58230.08849 Pa
