Answer:
And the force of ( Attraction or repulsion) between the poles A and D ( maximum or minimum)
Answer:
Assuming that you meant the final velocity of 50 m/s was reached in 10 s, the answer would be 5 m/s^2.
Explanation:

So we update that with the values that we have.

then simplify that using algebra to solve for a and we get 5 m/s^2
Answer:
A. A person would have the same mass, but weigh less.
Explanation:
Remember, even if you weigh less because of a change in gravity's force on your body, your body's mass is still the same.
Oil spill on land and in the oceans and kills wildlife like the great barear reef
Answer:
Weight required = 194.51 N
Explanation:
The elongation is given by

Length , L= 1.6 m
Diameter, d = 1.1 mm
Area

Change in length, ΔL = 2.8 mm = 0.0028 m
Young's modulus of copper, E = 117 GPa = 117 x 10⁹ Pa
Substituting,

Weight required = 194.51 N
