Answer:
M = I A definition of magnetic moment - current * area
A = π R^2 = π * (6.4E6)^2 = 1.3E14 m^2
I = 8E22 A-m^2 / 1.3E14 m^2 = 6.2E8 amperes
I = 620,000,000 amps
<u>Answer:</u>
The gauge pressure is 6670.8 Pascal
<u>Explanation:</u>
Given the height is 0.68 m
The Gauge pressure is determine by the formula,
Gauge pressure , P = hdg
Where h = 0.68 m
d = 1000
g = 9.81
Substituting the values in the formula of Gauge pressure, we get
Gauge Pressure = hdg =
Gauge Pressure = 6670.8
Therefore, the gauge pressure is 6670.8 Pascal
Answer:
A wheel and axle, force multipliers and a lever.
Explanation:
If Adam is pulling with a pulling force of 120N, and the nets pulling force is 200N, and they are both going north, then that means that Krystal would have a a pulling force of 80N north, as 200N- 120N is 80N. She would be pulling north because she is on the same side as Adam, helping to pull the sled upwards.

Answer:
The work done on the canister is 15.34 J.
Explanation:
Given;
mass of canister, m = 1.9 kg
magnitude of force acting on x-y plane, F = 3.9 N
initial velocity of canister in positive x direction, = 3.9 m/s
final velocity of the canister in positive y direction,
The change in the kinetic energy of the canister is equal to net work done on the canister by 3.9 N.
ΔK.E =
ΔK.E
The initial kinetic energy of the canister;
The final kinetic energy of the canister;
ΔK.E = 29.79 J - 14.45 J
ΔK.E = = 15.34 J
Therefore, the work done on the canister is 15.34 J.
