Answer:
increase
Explanation:
According to Einstein's photoelectric equation; the energy of a photon striking a metal surface is related to the kinetic energy of the ejected photoelectron by the formula;
KE= hf - hfo
Where h is the planks constant, f and fo refer to the frequency of incident photon and the threshold frequency respectively.
Hence, we can clearly see from the foregoing that the kinetic energy of the ejected photoelectron is proportional to the frequency of the incident photon.
Hence, if the frequency of the incident photon is increased, the kinetic energy of the ejected photoelectron increases also.
Answer:
r = 0.63 AU
Explanation:
In this question, we are interested in calculating the distance from the sun that the satellite should orbit.
From the question;
given time period of satellite is T = 0.5 year
Mathematically;
T is directy proportional to r^3/2
Hence;
T = constant * r^3/2
0.5/1 = r^1.5 / 1^1.5
( 1 is the the distance of the earth’s orbit to the sun in AU)
r = 0.63 AU
The answer is temperature, salinity, and density.
Oh jk haha LOL bye hahaha
