Answer:
Explanation:
The energy stored is E = 1/2 kx^2.
E1 = E2
1/2 k(1.3)^2 = 1/2 (2k)x^2
x^2 = 1/2 (1.3)^2
x = 1.3/sqrt(2) cm
x =0.919 cm
rate me thanks
Your answer is false because they are waves and have no mass.
Answer:
7ev
Explanation:
The Energy of an incident light is given as E = hf;
Where h is Planks constant
f is frequency
Also.
E = Eo + K.E
Where Eo is work function and K.E is kinetic energy.
Hence substituting the given values,
E = 3ev + 2ev = 5ev
The frequency of the incident wave if it's doubled the Energy would be doubled since E is proportional to f with other elements been constant.
Hence :E = 10ev
But K.E = E -Eo
= 10ev - 3ev = 7ev
Maximum Kinetic Energy is 7ev.
B. Location#2 with an altitude of 200 feet
Maybe because it is sort of shaped like part of a bell
