Answer:
Force, F = 2356.19 N
Explanation:
Given that,
Diameter of the circular tip, d = 1 mm = 0.001 m
Its radius, r = 0.0005 m
Pressure created, 
To find,
Force exerted on the nail.
Solution,
The pressure exerted by an object is equal to the force acting per unit area. Its formula is given by :
F = 2356.19 N
Therefore, the force exerted on the nail is 2356.19 N.
Answer:
Explanation:
Given
Weight of car 
mass of car 
velocity of car 
radius 
(a)Centripetal acceleration is given by
(b)Force that provide centripetal acceleration
(c)Friction force between car and tires is given by
where 
=coefficient of static friction
N=normal reaction
Centripetal force will balance the friction force
You force air from your lungs up through your larynx which is commonly called the voicebox
The formulas you will need are:
Kinetic energy = (1/2) (mass) (speed)² .
and
Potential energy = (mass) (gravity) (height) .
And of course,
Total energy = constant .
