the third answer is right.
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:
<em>The change of momentum of the dart is 0.84 Nw.s</em>
Explanation:
<u>Impulse and change of momentum</u>
The change in momentum of an object is its mass times the change in its velocity:
The change in the momentum can also be found by considering the force acting on it. If a force F acts for a time Δt, the change of momentum is given by:
The dart hits a dashboard with a net force of 14 N during the collision and stops in 0.06 seconds. The change of momentum is:
The change of momentum of the dart is 0.84 Nw.s
Answer: Can I get a picture???
here since string is attached with a mass of 2 kg
so here tension force in the rope is given as
here we will have
now we will have speed of wave given as
here we will have
now we know that frequency is given as
F = 100 Hz
now wavelength is given as
so wavelength will be 0.16 m
