Answer:
See explanation.
Explanation:
The energy density of an electric field is given by
The electric field at a distance due to the electron is
therefore,
putting in values for and we get:
(a).
For
(b)
For
(c).

Answer: a= 37m
Explanation: V= 15 m/s (Velocity) t= 0.41s (time) formula: a= v/t
15 m/s / 0.41 (15 divided by 0.41) = 36.583m
There are 2 significant digits, 36, you look at the third digit, either round up or down in this case up to 36. a= 37m
Answer:
3100.05 N
Explanation:
= Force on piston = 45 N
= Radius of piston
= Radius of plunger
From Pascal's law we have
The force is 3100.05 N
