One way to increase or decrease the strength of the magnetic field is to change the number of loops in the coil. The more loops you add, the stronger the field will become. The more loops you remove, the weaker the field will become.
Answer:
1176 N
Explanation:
We are given that
Mass of car=1280 kg
Mass of trailer==350 kg
Car exerts a horizontal force against the ground =N
Coefficient of friction=
We have to find the force exerted by car on the trailer.
Substitute the values then we get
Force exert on the trailer
Hence, the car exerts force on the trailer=1176 N
