It would be a plane mirror, since the average household mirror is flat.
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:1.5
Explanation:
Given
mass of first cart 
initial Velocity 
mass of second cart 
In the absence of External Force we can conserve momentum
Final kinetic Energy of two masses
Initial Kinetic Energy
This is false. An unbalanced charge, whether negative or positive, is called a
<em>static charge</em>. This explains why a balloon 'sticks' to your wool sweater. This is because of the static charge, which is caused by the imbalance of charges due to the electrons losing and gaining energy which is achieved by the mere action of rubbing.
Answer:
The pushing force and the skier's mass
(A) is correct option.
Explanation:
Given that,
Mass = 64 kg
Weight = 608 N
Velocity = 21 m/s
Forward force = 45 N
We need to calculate the reaction force of the snow pushing on the skier
Using given data,
The reaction force of the snow pushing on the skier is equal to the pushing force and the skier's mass.
Hence, The pushing force and the skier's mass
(A) is correct option.
