A transport truck pulls on a trailer with a force of 600N [E]. The trailer pulls on the transport truck with a force equal to 600 N no matter what the acceleration of the truck. Option c is correct.
According to Newton's third law of motion, every action has an equal and opposite reaction. As well as the action and reaction are always acted in pairs.
Based on the law of action-reaction,
A transport truck pulls on a trailer with a force of 600N [E]. The trailer pulls on the transport truck with a force greater than 600 N if the truck is accelerating.
If the truck is moving at constant velocity the acceleration is zero resulting in no force exerted by the truck on the trailer
The force by which the transport truck pulls on a trailer is equal to the force by which the trailer pulls the truck.
F₁ is the force by which the transport truck pulls on a trailer
F₂ is the force by which the trailer pulls the truck
F₁=F₂
A 600N [E] pulling force is applied by a transport vehicle to a trailer. Regardless of the transport truck's acceleration, the trailer pulls on it with a force of 600 N.

Answer:
a) 240 m
b) 122 m/s
c) 28 m/s²
Explanation:
Given:
Equation for motion
x = 38t + 14t²
a) average velocity during first 3 seconds
average velocity =
now,
distance, at t = 0 s
x = 38 × 0 + 14 × 0² = 0 m
distance, at t = 3 s
x = 38 × 3 + 14 × 3² = 240 m
therefore,
average velocity = = 80 m/s
b) instantaneous velocity of the proton at t = 3.0 s
Instantaneous velocity, v =
or
Instantaneous velocity, v =
= 122 m/s
c) instantaneous acceleration of the proton at t = 3.0 s
Now,
Acceleration = = 0 + 28 = 28 m/s²
An antenna’s receiving circuit select electromagnetic radio waves of a certain frequency and reject all others. This is because an antenna IS an electromagnetic radiator that creates an electromagnetic field that scatters from the transmitting antenna to the receiver’s antenna.
