Explanation:
Q7Answer=If light meets a rough surface, each ray obeys the law of reflection. However, the different parts of the rough surface point in different directions, so the light is not all reflected in one direction. Instead, the light is reflected in all directions. This is called diffuse scattering .

d = distance to which the grocery cart is pushed = 18 m
f = frictional force = 37.5 N
θ = angle of force below the horizontal = 27.5 deg
W = gravitational force in downward direction
Θ = angle between gravitational force in down direction and displacement in horizontal direction = 90
U = work done on the cart by gravitational force
work done on the cart by gravitational force is given as
U = W d CosΘ
inserting the values
U = W (18) Cos90
U = 0 J
The answer is b. Velocity
Answer:
340cm = 3.4m
Explanation:
When converting units: cm to m, then you need to divide the cm by 100 to get its unit in m.
