Explanation:
It is given that,
Speed of the sports car, v = 85 mph = 37.99 m/s
The radius of curvature, r = 525 m
Let
is the normal weight and
is the apparent weight of the person. Its apparent weight is given by :

So, 



or

Hence, this is the required solution.
Answer:
One when it enters the glass slab from air and second time when it enters the air through glass slab. When light rays travelling through air enters glass slab, they get refracted and bend towards the normal. Now the direction of refracted ray changes again when it comes out of the glass slab into air.
A decrease in mass will decrease an objects weight because
weight = mass x gravitational constant
Answer:
accuracy refers to the deviation of a measurement from a standard or true value of the quantity being measured
It would be f=ma so
a.
f=m <span>× a</span>
