Waves have the
characteristic that they can of transmit energy. This characteristic depend
only on the medium and its properties. Electro-mechanical waves do not need
medium to transfer its energy, is capable of transmitting it through empty
space (vacuum).
<span>Mechanical
waves require a medium in order to transport their energy. Sound waves are an
example of mechanical way. They can not
travel through vacuum. </span>
Explanation:
M₂ = Fr²/GM₁
M₂ = [(132N)(.243m)²]/[(6.67*10^-11N*m²/kg)(1.175*10^4kg)]
M₂ = (7.79N*m²)/(7.84*10^-7N*m²)
M₂ = 9.94*10^6 kg
Answer: 8.3 hours
Explanation:
time= distance divided by speed so:
150 divided by 18= 8.3 hours
Answer:
Theory
Explanation:
Conservation of energy is explained as a scientific law and not a theory because it does not explain why energy is conserved.
A law is a the statement of a scientific fact. It is a product of repeated experiment and observation through time. Most laws do not explain the reason for the logic behind their premise.
A theory on the other hand provides an explanation for an observed phenomenon. Most theories are no immutable. They are often changed when new finds are reported or made.
Laws are immutable and they stand still.
