Answer:
Acceleration of the car will be 
Explanation:
We have given mass of the ball m = 1600 kg
Force in north direction F= 7560 N
Resistance force which opposes the movement of car 
So net force on the car 
According to second law of motion we know that F=ma
So 

The force exerted on the tires of a car that directly accelerate it along a road is exerted by the road friction.
<h3>What is force?</h3>
Force is defined as the product of mass and acceleration of an object.
Friction is defined as the force that resists the movement of an object over another.
Therefore, the force exerted on the tires of a car that directly accelerate it along a road is exerted by the road friction.

Answer:
wavelength is 666.6933 ×
m
Explanation:
given data
Two slits separated d = 0.425 mm
screen away D = 3.13 m
tenth bright line (y) = 49.1 mm
to find out
The wavelength of the light
solution
let angle θ at which bright fringed occurs
so that
tanθ = y / D
here D id slits to screen distance and tanθ = θ
and
construction interference equation
sinθ = m β / d
and here sinθ = θ and β is wavelength
θ = m β / d
and
θ = m β / d
y / D = m β / d
β = y d / Dm
wavelength = 49.1
× 0.425
/ 3.13 (10)
wavelength = 49.1
× 0.425
/ 3.13 (10)
wavelength is 666.6933 ×
m
