Answer:
0.0360531138247 V/m
Explanation:
= Resistivity of gold =
(General value)
I = Current = 940 mA
d = Diameter = 0.9 mm
A = Area = 
E = Electric field
Resistivity is given by

The electric field in the wire is 0.0360531138247 V/m
Answer:
Kepler's First Law: each planet's orbit about the Sun is an ellipse. The Sun's center is always located at one focus of the orbital ellipse. The Sun is at one focus. The planet follows the ellipse in its orbit, meaning that the planet to Sun distance is constantly changing as the planet goes around its orbit.
Answer:
1500 divided by 150(15m x 10m/s^2) = 10
Answer:
Part a)

Part b)

Part c)

Explanation:
Part a)
Net pulling force on the chain is due to weight of the part of the chain which is over hanging
So we know that mass of overhanging part of chain is given as

now net pulling force on the chain is given as

now acceleration is given as



Part b)
Tension force in the part of the chain is given as





Part c)
velocity of the last link of the chain is given as


now integrate both sides
