Emissivityis a measure of how much thermal radiation a body emits to its environment. On the other hand we have that reflectivity is a measure of how much is reflected, and transmissivity is a measure of how much passes through the object. If a body is required to be ideally reflective to its maximum efficiency, the body should NOT have the property of transmissivity or emissivity. Therefore it should be 0 its emittivity.
Correct answer would be A : ZERO.
There would be martial law (just elaborate on the definition) and the population would go awry(elaborate on subject)
Answer:
Explanation:
Often times, the property of air masses is a function of where they originate from especially with respect to latitude.
An air mass is certain amount of air with some unique set of temperature and vapor component.
- Air masses differs from places to places based on where they originate.
- Continental air masses are usually dry and cold because there is little to no water on a land mass.
- Air masses that originates from the surface of the ocean are predominantly moist.
- In polar regions, the air mass is cold.
- Around the tropics, they are usually warm due to insolation here.
Answer:
Part a)
Part b)
Explanation:
Part a)
Electric field due to large sheet is given as
now the electric field is given as
Now acceleration of an electron due to this electric field is given as
Now work done on the electron due to this electric field
So work done is given as
Part b)
Now we know that work done by all forces = change in kinetic energy of the electron
so we will have
