Answer:
The answer is A. C and O..
Answer:
0.306mm
Explanation:
The radius of the conductor is 3mm, or 0.003m
The area of the conductor is:
A = π*r^2 = π*(.003)^2 = 2.8*10^-5 m^2
The current density is:
J = 130/2.8*10^-5 = 4.64*10^6 A/m
According to the listed reference:
Vd = J/(n*e) = 4.64*10^6 / ( 8.46*10^28 * 1.6*10^-19 ) = 0.34*10^-6 m/s = 0.34mm/s
The distance traveled is:
x = v*t = 0.34 * .90 = 0.306 mm
I don’t understand the question
That depends on WHERE the rig is, because
weight = (mass) x (acceleration of gravity where the object is) .
-- If the truck is on Mars, then
Weight = (36,000 kg) x (3.71² m/s²) = 133,560N.
-- If the truck is on the moon, then
Weight = (36,000 kg) x (1.62 m/s²) = 58,320N.
-- If the truck is on Earth, then
Weight = (36,000 kg) x (9.81 m/s²) = 353,160N.
It all depends.
