Use the equation Vf=Vi+(A)(t)
since you're trying to find the initial velocity, rearrange the equation to say Vi=Vf-(A)(t)
so, Vi=230-(42)x(2.5)
final answer: Vi=125m/s
Answer:
The direction of the induced current in the coil is clockwise
Explanation:
This is based on Lenz's law that states that the direction of the induced current opposes the magnetic field that produces it. As the magnetic field becomes stronger, the induced current in the coil moves in a clockwise direction in order to oppose the magnetic field.
Answer:
0.00789pa
Explanation:
since pressure=force/area
=400/0.5
=800N/m2
1.013*10^5N/m2=1pascal
800N/m2=xpascal
therefore it becomes,800/1.013*10^5
=0.00789pascal
Given that,
Horizontal force, F = 600 N
A mover pushes a dresser 9 meters across a bedroom.
To find,
The work done by the mover.
Solution,
The work done by an object is given by :
W = Fd
Where d is distance
W = 600 N × 9 m
= 5400 J
So, the work done by the mover is 5400 J.
