Answer:
76 V/m
Explanation:
= Electric potential at initial location = 119 V
= Electric potential at final location = 43 V
= distance between initial and final location = 1 m
= magnitude of electric field
Magnitude of electric field is given as
= 76 V/m
Answer: 6,000 pounds ( lbs)
1 ton equals 2,000 pounds 3 X 2,000lbs = 6,000lbs
Answer:
Explanation:
If one assume that each turn is like a strand of electromagnet, which can then be added up. Therefore, increase in the number of turns will yield to increase in the magnetic strength. Also if the current increases, then there will be increase in the magnetic field strength.
From Ohm's law
V = IR
I = V/R
That is a direct increase in voltage will lead to increase in current.
Increase the voltage of the battery and increases the number of turns of the coil. Will suit the situation
To solve this problem we will apply the principles of conservation of energy, for which we have to preserve the initial kinetic energy as elastic potential energy at the end of the movement. If said equality is maintained then we can affirm that,
Here,
m = mass
k = Spring constant
x = Displacement
v = Velocity
Rearranging to find the velocity,
Our values are,
Replacing our values we have,
Therefore the velocity is
