Answer:
A wave in which the medium vibrates at right angles to the direction of the propagation is called transverse wave.
Answer:
the two factors are the mass of the objects and the coefficient of friction between them

Explanation:
The two postulates of special theory of relativity
Postulate 1: The law of physics are invariant under any of inertial frame of reference.
Postulate 2: The velocity of light is remains same in each ans every frame of reference and independent of relativity.
They are differ from classical mechanics that in classical mechanics there is no change in mass and length in relative velocity but in relativistic mechanics it changes.
These two postulates implements in phenomenon like time dilation , length contraction etc.

Answer:
Explanation:
The answer is C. Both options are correct
Answer:
615 J
Explanation:
internal energy (U) = 504 J
heat lost (q) = 111 J = - 111 J (negative sign is because heat is lost)
work done = 222 J
what is the final energy in the system
total energy = final energy - initial energy
final energy = total energy + initial energy
where
initial energy = 504 J
total energy = 222 - 111 = 111 J
final energy = 504 + 111 = 615 J
