More quiclky
Explanation:
In Earth, there is a gravitional force. So that forces pushed you down faster.
Hey all you can do is type the question on the internet and click on the one that has the same title as yours and the answers will be there im taking physics and i do that all the answers will be there
true ........i really dont kno but ok hope this helps
Answer:
Explanation:
For a drop in equilibrium, the weight is equal to the electric force (in magnitude):
where here we have
is the weight of the drop
is the magnitude of the electric force, which can be rewritten as
where
q is the charge of the oil drop
is the magnitude of the electric field
Substituting into the equation and solving for q, we find the charge of the oil drop:
Answer: 5.41 V
Explanation:in order to explain this result we have to use the Ohm law given by:
ΔV=R*I where R is the resistance which is equal R= ρ*L/A . ρ is the resistivity, L the length of the wire and A is the cross section. I is the current.
Then we have
ΔV=ρ*L*I/A= 1.68 * 10^-8 Ωm*93.4 m*72.5A/2.1* 10^-5 m^2=5.41 V
