The work done is equal to the change in potential energy which is:
P.E = mgh
P.E = 500 x 9.81 x 15
P.E = 73,575 J
Power = work / time
Power = 73,575 / 20
Power = 3,700 Watts
Answer:
83816746.4254 m/s
Explanation:
m = Mass of electron = 
q = Charge of electron = 
V = Voltage = 
The kinetic energy of the electron is

Energy is given by

Balancing the energy

The velocity of the electrons is 83816746.4254 m/s
The related concepts to solve this problem is the Glide Ratio. This can be defined as the product between the height of fall and the lift-to-drag ratio. Mathematically, this expression can be written as,

Replacing,


Converting this units to miles.


Therefore the glide in terms of distance measured along the ground is 7.2916miles
Answer:
angle = 18.40 degree
Explanation:
given data
force = 95 N
distance = 0.50 m
torque = 15 N · m
to find out
angle between the wrench handle and the direction of the applied force
solution
we will apply here torque equation that is express as
torque = distance × force × sin(θ) ...................1
put here value we will get angle that is
15 = 0.50 × 95 × sin(θ)
sin(θ) = 0.315789
θ = 18.40 degree
