80 m/s this should be right
Answer:
Explanation:
charge of the electron = e
mass of the electron = m
Force due to electric field = F
initial velocity = 0
time taken = T
Electric field is the region around a particle which is charge where in a force is exerted on another particle which is charged.
Force on electron due to presence of uniform electric field (E):
F = e E
⇒
17 , d . because a force is being applied but it is not moving .
19 . is c .
20 .b .
21 . d .
31 . d .
Answer:
d=1.49×1011m
Explanation:
Velocity is defined as the rate of travel, and can be found using the distance formula.
velocity=distancetime
Rearranging this formula we can solve for distance given velocity and time of travel.
d=vt
We are given velocity and time, and so can solve for distance, but if we plug in the values given;
d=(3.00×108m/s)(8.3minutes)
We can see that the units do not match up. Since seconds are the SI unit for time, we will need to convert 8.3 minutes to seconds.
t=(8.3minutes)(60seconds/minute)=(498s)
Now our units work out and we can solve for distance.
= 15.85
Its A according to Ed Genuity
