Answer:
b) weaker
Explanation:
Hot rolled steel is generally weaker than the cold drawn steel. The yielding stress of cold rolled steel is higher than than hot rolled steel. At the same time the crystal structure remain the same in cold rolled steel. Giving it a better surface finish and closer tolerances. The strength and hardness of a cold roll steel is higher than the hot rolled steel

Explanation:
The distance covered by the car is given by
where v is the velocity of the car and t is the time interval.
The car is traveling with a constant velocity of v=8 m/s, and the time interval is t=10 s, therefore if we substitute these numbers into the equation, we find:
By the laws of reflection, we know,
Angle of reflection = Angle of incidence
angle of reflection = 30%
In short, Your Answer would be 30
Hope this helps!
