Newtons Law works with friction, gravity, and falls.
Also, the formula would be: F = ma
Force = acceleration * mass
Example: The force on a bike is 30 Newtons. The mass of the bike is 6 kg. What is the acceleration of the bike?
The force of a test charge would be doubled if the electric field is doubled.
Answer: Option A
<u>Explanation:</u>
Electric field is the region or range up to which a charge particle will have its influence of electric energy on another charged particles. So the experienced force by the test charge up to a certain range is defined as the electric field of that charged particle.
This means that the electric field strength is inversely proportionate to the test charge and directly proportionate to the force acting on the test charge. As
,

So, force will be product of electric field strength with test charge. Thus,

So, if there is increase in the electric field, then there will be increase in the force of the test charge. Thus, if the electric field is doubled thereby the force of a test charge will also be doubled.
Answer:
Explanation:
Set the equations for work and kinetic energy equal to each other. Work equals force times distance and kinetic energy equals one-half the mass of the object times its velocity squared, so F_d = (m_ ÷ _2)_v2. Substitute the measurements for force, distance and mass into the equation.
The wavelength of a wave varies inversely as its frequency, i.e.
W ∝ 1/F
A wave decreases its frequency from 600kHz to 300kHz, so let's calculate the scaling factor of W due to the change in F.
k = 1/(300/600) = 2
To find the new wavelength, multiply the original wavelength by k:
W = 2×129m
W = 258m
The magnitude of static friction force is f_s = 842.8 N
Explanation:
Write down the values given in the question
The wheel of a car has radius r = 0.350 m
The car applies the torque is τ = 295 N m
It is said that the wheels does not slip against the road surface,
Here we apply a force of static friction,
It can be calculated as
Frictional force f_s = τ / r
= 295 Nm / 0.350 m
f_s = 842.8 N
