Answer:
Magnetic energy and electromagnetic energy form of potential energy followed by a form of kinetic energy.
(B) is correct option.
Explanation:
Given that,
Lists a form of potential energy followed by a form of kinetic energy
We know that,
Sound energy :
The movement of energy through object it is called sound energy. When a object produced vibration by force then it moves in wave.
Sound wave is example of kinetic energy.
Nuclear energy :
The store energy in the nucleus of the atom it is called nuclear energy. This energy released when occurs fusion and fission.
Nuclear energy is the example of potential energy
Magnetic energy :
Magnetic energy is a type of potential energy which is depend on distance and position in the magnetic field.
Electromagnetic energy :
Electromagnetic energy is light energy. it is type of kinetic energy.
Gravitational energy :
Gravitational energy is a type of potential energy. It is an energy related with gravity or gravitational force.
Elastic energy :
The store energy in elastic object it is called elastic energy. This energy is a type of potential energy.
Electrical energy :
The movement of electrons is called electrical energy. When electrons move through a wire then it is are called electricity. Electrical energy is type of kinetic energy.
Hence, Magnetic energy and electromagnetic energy form of potential energy followed by a form of kinetic energy.
(B) is correct option.
Answer:
962.5 Hz
Explanation:
given,
frequency = 8.94 GHz
speed of the trap = 32.3 m/s
frequency shift = ?
frequency of shift is calculated using formula
c is the speed of light
f_o is the frequency of the radar gun
the frequency of shift is equal to 962.5 Hz
The heat transfer in this event is through physical contact, there are other ways to transfer heat (radiation, convection etc.)but in this case. The channel or mode of heat transfer is through surface contact. Thus when the surface of the metal ball comes in contact with the ice block. Only portion is actually in contact.
the answer i think is asphalt and plastic
Answer: 2.67 m/s
Explanation:
Given
Mass of block A is
mass of block B is
The initial velocity of block A
the initial velocity of block B is
After collision velocity of block A is
Conserving momentum
The momentum of block A after the collision is
Therefore, there is no change in sign.
