Answer:
magnetic resonance imaging
Answer:
r1 = 5*10^10 m , r2 = 6*10^12 m
v1 = 9*10^4 m/s
From conservation of energy
K1 +U1 = K2 +U2
0.5mv1^2 - GMm/r1 = 0.5mv2^2 - GMm/r2
0.5v1^2 - GM/r1 = 0.5v2^2 - GM/r2
M is mass of sun = 1.98*10^30 kg
G = 6.67*10^-11 N.m^2/kg^2
0.5*(9*10^4)^2 - (6.67*10^-11*1.98*10^30/(5*10^10)) = 0.5v2^2 - (6.67*10^-11*1.98*10^30/(6*10^12))
v2 = 5.35*10^4 m/s
Answer:
The value of the fund today is $13831.72
Explanation:
Let us calculate the value at the end of each year, step by step. An annual decrease of 3% corresponds to a multiplier 1.0-0.03 = 0.97. An increase of 7% corresponds to 1.07.
Value at the end of
year 1: 12000 * 0.97
year 2: 12000 * 0.97 * 0.97
year 3: 12000 * 0.97 * 0.97 * 1.07
year 4: 12000 * 0.97 * 0.97 * 1.07 * 1.07
year 5: 12000 * 0.97 * 0.97 * 1.07 * 1.07 * 1.07 = 13831.72
The value of the fund today (end of year 5) is $13831.72
Answer:
Option b. Dark spot
Explanation:
Michelson interferometer gives the path difference of the light as path difference, d as twice the distance moved or covered by the mirror 
, x and is given as:
d= 2x
Since, its an even multiple, we obtain a bright fringe
now, when the move half the distance, i.e., 
Therefore, the path difference for half the distance is:
d = x
As it is clear that its an odd multiple which correspond to dark spot as the final image
