Gamma rays have the shortest wavelength.
First we'll calculate the energy it posesses
G.P.E = mgh = 0.2 * 10 * 100 = 200 J
Now we'll calculate the temperature rise
Q = m * c * (t2 - t1)
Q/(m * c) = t2-t1
t2 = Q/(m * c) + t1 = 200/(0.2 * 400) + 0 = <span>2.5 C</span>
Answer:
iron
Explanation:
Increasing the number of coils of wire wrapped around the nail increases the strength of the electromagnet, as measured by the number of paper clips the magnet can pick up
Answer:
11.106 Mev.
Explanation:
Sr⁸⁸ → Sr ⁸⁷ + ₀n¹
87.905612 86.908877 1.008664 ( atomic masses in amu )
mass defect = ( 86.908877 + 1.008664) - 87.905612 = .011929 amu.
Equivalent energy in MeV = .011929 x 931 = 11.106 MeV
