Answer:
Explanation:
The speed increased from 2.0 * 10^7 m/s to 4.0 * 10^7 m/s over a 1.2 cm distance.
Let us find the acceleration:
Electric force is given as the product of charge and electric field strength:
F = qE
where q = electric charge
E = Electric field strength
Force is generally given as:
F = ma
where m = mass
a = acceleration
Equating both:
ma = qE
E = ma / q
For an electron:
m = 9.11 × 10^{-31} kg
q = 1.602 × 10^{-19} C
Therefore, the electric field strength of the electron is:
I think that would be c) mirror because mirrors reflects light and can't create it.

Answer:
Callisto. As Io is geologically active body.
Explanation:
Io and Callisto are 2 of the Galilean moons of Jupiter. Io is most geologically active body in the solar system which means that a lot of volcanic activity takes place over there whereas Callisto is not geologically active.
This is the reason that probability of finding an impact crater will be more on Callisto than Io. As the craters might get filled with volcanic eruptions.
