Answer:
The electric field strength at the midpoint of the line joining the charges is zero (0)
Explanation:
Given that the two charges are both positive (same charge) and are equal in magnitude that is 6uC. The electric field strength at the midpoint of the line joining the two charges will be equal and opposite in magnitude, therefore they will cancel each other out and the electric field strength at this point will be equal to zero.
It is false it has straight sirface
Answer:
9.38J
Explanation:
mass = 0.425kg
height (h) = 2.25m
g = 9.81m/s^2
Gravitational potential energy (PE) = mgh
Plug in all info you got:
(0.425kg)(9.81m/s^2)(2.25m) = 9.38J
20m/s, honestly I have know idea what the asnwer is but if i had to guess, this would be my answer.
Distance = speed/time
width/distance given is 2.9*10^3 miles
1 mile=1.6*10^6mm
total distance now is 2.9*1.6*10^9
speed is 25 mm/yr
plug the values,
therefore the rift takes approximately 185600000 years for a width <span>of 2.9 x 10^3 mi.</span>
