Answer:
33705 N
Explanation:
We are given that
Mass of cabin=550 kg
Maximum load=2600 kg
Total mass,m=550+2600=3150 kg
Initial velocity=u=0
Final velocity=v=2.7 m/s
Time=3 s
We have to fine the tension of the elevator rope to withstand.
Acceleration=
Net force=
Where
Using the formula
Answer:
Force, F = 500 N
Explanation:
Given that,
Power expanded, P = 1000 W
Distance moved by piano, d = 10 m
Time taken, t = 5 s
To find,
The force exerted by the person
Solution,
The rate at which the work is being done is called power delivered. Its formula is given by:
W is the work done, W = F × d
On rearranging the above formula to find F as :
F = 500 N
Therefore, the force exerted on the person is 500 N. Hence, this is the required solution.
A current carrying wire is placed vertically. The magnetic field around the wire is rotating clockwise around the wire. The current is moving from top to bottom
Holding a current carrying wire in your right hand with the thumb pointing in the direction of current flow, the fingers wrapping the wire will portray the magnetic lines of force direction, following the right-hand thumb rule.
As a result, a current carrying conductor is vertically held. If you follow the rule, the current should be passed through it to generate a clockwise magnetic field around the conductor from top to bottom.
