A mass m = 14 kg is pulled along a horizontal floor, with a coefficient of kinetic friction μk = 0.08, for a distance d = 7.8 m.

then the mass is continued to be pulled up a frictionless incline that makes an angle θ = 30° with the horizontal. the entire time the massless rope used to pull the block is pulled parallel to the incline at an angle of θ = 30° (thus on the incline it is parallel to the surface) and has a tension t = 32 n. 1) what is the work done by tension before the block gets to the incline? j 2) what is the work done by friction as the block slides on the flat horizontal surface? j 3) what is the speed of the block right before it begins to travel up the incline? m/s 4) how far up the incline does the block travel before coming to rest? m 5) what is the work done by gravity as it comes to rest? j 6) during the entire process, the net work done on the block is: positive negative zero

Two positive charges of 6 µC are separated by a distance of 50 cm in air. What is the electric field strength at the midpoint of
attashe74 [19]

Answer:

The electric field strength at the midpoint of the line joining the charges is zero (0)

Explanation:

Given that the two charges are both positive (same charge) and are equal in magnitude that is 6uC. The electric field strength at the midpoint of the line joining the two charges will be equal and opposite in magnitude, therefore they will cancel each other out and the electric field strength at this point will be equal to zero.

A motor transfers 12 kJ of energy in 30 s. Calculate its power.
Diano4ka-milaya [45]

Answer:

power=400Watt

Explanation:

work done =12kJ=12×10³=12000j

time taken=30s

power=?

as we know that

power=work done/time taken

power=12000J/30s

power=400Watt

i hope this will help you :)
