Answer:
As an object falls from rest, its gravitational potential energy is converted to kinetic energy.
Explanation:
It converts to kinetic energy because it is moving
Answer:
a hydrometer is the tool used to measure
Answer:
I think 5 km/h but I am not sure
It's an electric motor that converts electric energy into Mechanical energy
An excited atom can return to its ground state by absorbing electromagnetic radiation is false about the electromagnetic radiation.
Option B
<u>Explanation</u>:
In the scope of modern quantum theory, the term Electromagnetic radiation is identified as the movement of photons through space. Almost all the sources of energy that we utilize today such as coal, oil, etc are a product of electromagnetic radiation which was absorbed from the sun millions of years ago.
Various properties of electromagnetic radiations are a directly proportional relationship between the energy and the frequency, Inverse proportionality between frequency and the wavelength, etc. Hence, we can conclude that an "excited atom" can never return to its ground state by assimilating electromagnetic radiation and the 2nd statement is false.
