According to Edge, the answers is
<h3>3100 V</h3>
and
<h3>200v</h3>
Answer:
4.36 seconds
Explanation:
According to the question;
- Force is 550 N
- Mass of the car is 1200 kg
- Velocity of the car is 2.0 m/s
We are needed to find the time the car must the tow track pull the car.
- From Newton's second law of motion;
- Impulsive force, F = Mv÷t , where m is the mass, v is the velocity and t is the time.
Rearranging the formula;
t = mv ÷ F
Thus;
Time = (1200 kg × 2.0 m/s²) ÷ 550 N
= 4.36 seconds
Thus, the time needed to pull the car is 4.36 seconds
Answer:
Approximately 
.
Explanation:
Assuming that there is no other force on this vehicle, the 
force from the road would be the only force on this vehicle. The net force would then be equal to this 
force. The size of the net force would be 
.
Let 
denote the mass of this vehicle and let 
denote the net force on this vehicle.
By Newton's Second Law of motion, the acceleration of this vehicle would be proportional to the net force on this vehicle. In other words, the acceleration of this vehicle, 
, would be:
.
For this vehicle, 
whereas 
. The acceleration of this vehicle would be:
.
<span>Voltage overcomes the resistance of the electromagnet winding to force a current through that resistance. The field strength is proportional to the coil current. More voltage pushes more current. More voltage builds up the current faster, as well as forcing it to a higher final value. </span>
Do u know Chinese ?if yes I can explain to u easily
