The net force of the car <u>is 6000 N.</u>
Why?
To calculate the net force of the car during the given time, we first need to calculate its acceleration, and then, use Newton's Second Law equation to calculate the net force.
We can calculate the acceleration of the car during the given tieme using the following equation:

Substituting the given information, we have:

Now that we have calculated the acceleration, we can calculate the net force:

Hence, we have that the net force is equal to 6000N.
Have a nice day!
Answer:

Explanation:
B at point 7.0 cm radially outward is to find out?
Now for field strength in case of parallel plates in given as



For the second part as Capacitor is fully charged no more flow of current could take place hence
I= Current =o
so B = 0
Answer:
The thrust of the jet engine is 4188.81 N.
Explanation:
Given that,
Speed = 260 m/s
Rate in air= 53.3 kg/s
Rate of fuel = 3.63 kg/s
Relative speed = 317 m/s
We need to calculate the rate of mass change in the rocket
Using formula of rate of mass

Put the value into the formula


We need to calculate the thrust of the jet engine
Using formula of thrust

Put the value into the formula


Hence, The thrust of the jet engine is 4188.81 N.
