no additional force is needed to bring the car to equilibrium.
the car is going forward on a level road at constant velocity. that means the velocity of the car remain same all the time.
we know that acceleration is the time rate of change of velocity. since the velocity of car does not change , the acceleration of the car must be zero.
according to newton's second law , net force is given as
F = ma
where F = net force , m = mass , a = acceleration
since a = 0 ,
F = m (0)
F = 0 N
since the net force is zero on the car , the car is already in equilibrium and hence no additional force is needed to bring equilibrium
The friction force has a 2 N force.
The static friction coefficient that exists between the project and the surface should be multiplied to provide the friction force. When the surface is thought of as horizontal, the normal force should be equal to the weight of the block and should also be directed in the opposite direction.
the friction force is therefore
= 0.5*N = 0.5* (10)
= 5
The friction force is greater than the force acting on the block, which is why there is no movement of the object even though it should be the reverse. Furthermore, the actual force needs to be equal.
The friction force here should therefore be 2N.

A 2.0-N force acts horizontally on a 10-N block that is initially at rest on a horizontal surface. The coefficient of static friction between the block and the surface is 0.50. What is the magnitude of the frictional force that acts on the block?
Answer:
0.25 m
Explanation:
Electromagnetic waves consist of oscillations of the electric and the magnetic field, oscillating in a plane perpendicular to the direction of motion the wave.
All electromagnetic waves travel in a vacuum always at the same speed, the speed of light, whose value is:
Microwave is an example of electromagnetic waves.
The relationship between wavelength and frequency for an electromagnetic wave is:
where
is the wavelength
is the speed of light
f is the frequency
For the microwave in this problem,
So its wavelength is
Answer:
When plane waves cross a boundary at a non-zero angle to the boundary, each wavefront experiences a change in <u>direction</u> and <u>wavelength</u>
Explanation:
Waves that cross the boundary from one medium to another, that have different densities at an angle to the boundary between the two medium is refracted (bent) in the second medium and experiences a change in direction and speed due to a change in the wavelength of the wave
It would fall at about/ around 96 mph
