Answer:
No, because pressure is determined by force and the area over which that force acts.
Explanation:
Answer:
Explanation:
By Einstein's Equation of photoelectric effect we know that
here we know that
= energy of the photons incident on the metal
= minimum energy required to remove photons from metal
= kinetic energy of the electrons ejected out of the plate
now we know that it requires 351 nm wavelength of photons to just eject out the electrons
so we can say
here we know that
now we have
now by energy equation above when photon of 303 nm incident on the surface
Answer:
E.) Circuit Breaker is the correct answer.
Explanation:
Circuit Breaker is an automated electrical device that is designed to control and stop the excessive current flowing if the crosses a particular level and it protects the electrical circuit from the damage that can be caused due to overload of current that is the reason Circuit Breaker is called protective device.
There are different types of circuit breakers such as oil circuit breaker, vacuum circuit breaker, outdoor circuit breaker, Spring operated circuit breaker, Hydraulic circuit breaker and Medium-voltage circuit breaker, etc.
Everything but wormholes can be derived from the theory of relativity
