Differences:
An electrical motor converts electrical energy into mechanical energy,where as a generator converts mechanical energy into electrical energy.
The principle of a electric motor if there is a change of the magnetic field across a conductor electrons are forced to move in a direction perpendicular to the direction of the magnetic field,where as in a generator if a charge is moving in a magnetic field, a force acts on the charge in a direction perpendicular to both the velocity of the charge and the magnetic field.
similarities:
Both electric motor and generator work on the magnetic effects of electric current.
Both have the armatures to rotate the loop.
Answer:
20 mph
Explanation:
Granny stopped from 50mph,
Her deceleration per unit time is
a = 50 - 0 = 50m/hr^2
This is also the amount of deceleration you experience per unit time (because both cars are identical), therefore your final speed with which you collide with the truck will be,
50 = 70 - v
V = 70 - 50 = 20mph
Answer:
D
Explanation:
The direction that positive charge would move
The correct answer is <span>Montana.
In fact, we see from the table that Montana is the state with the largest amount of coal mined in 2005: 120 billion tons, while all the other states have a smaller amount of coal mined (37, 68 and 78, for West Virginia, Wyoming and Illinois, respectively).</span>
Answer:
Anaerobic
Explanation:
aerobic: <em>relating to, involving, or requiring free oxygen.</em>
anaerobic: <em>relating to, involving, or requiring an absence of free oxygen.</em>
