Answer;
=0.43 m/s²
Solution;
There will be the tension in the cable, T, upwards and the weight of the elevator, mg, downwards.
By Newton's second law, the sum of the forces will be equal to mass×acceleration.
Resultant force = m × a
Then T - mg = ma so the tension in the cable is
T = m(g+a)
The cable will break when T = 21,800 N
Solving for a, that happens when
a = 21800/2130 - g
= 10.23 - g (in m/s^2)
If you're using g = 9.8 m/s^2
Then the maximum acceleration allowed is 10.23-9.8 = 0.43 m/s^2
Answer:False
Explanation:
Turn the key to lock is not advisable as it lock the steering wheel and may create a dangerous situation.
Following steps can be taken in this situation
- Try to press the brake to stop the vehicle
- Shift gear to neutral in order to cease the acceleration of car.
- Try to lift the gas pedal in order to decrease the velocity of car.
I’d say it’s 8 or 80
Hopefully this helps sorry
Answer:
Explanation:
Electric forces exist among stationary electric charges; both electric and magnetic forces exist among moving electric charges. ... The magnetic force between two moving charges may be described as the effect exerted upon either charge by a magnetic field created by the other.
