The diameter of an automobile tire is closest to

slamgirl [31]

Answer:

(1) 10^−2 m

Explanation:

The diameter of the tire of an automobile is generally expressed in centimetres; we can say that the diameter of a tire is generally about

d = 20 cm (20 centimetres)

Now we have to verify which option is closest to this value. To do that, we have to keep in mind the equivalence between metres and centimetres; in fact, we have:

$1 cm = 10^{-2} m$

This means that we can rewrite the diameter of the tire of a car as

$d=20 cm = 20\cdot 10^{-2} m$

By comparing it with the given options, we see that the closest option is

(1) 10^−2 m

which is therefore the correct answer.

If a person (weighs 70kg) jumped of a moving car (at 100km/h) and fell on asphalt what is the amount of force applyied to his bo

jok3333 [9.3K]

Answer:

The amount of force applied to his body is 1944.44 N

The chances of the person dying is very high owing to the high impact force with which the person would experience when he or she lands on the asphalt road due to the jump out of the moving car.

Explanation:

We all know that,

F = Ma where,

F = Force

M = weight of the person

a = acceleration or velocity of the moving car

Therefore;

F = { 70 x (100 x 1000) } / [3600]

= [7 000 000] / 3600

= 1944.44 N
