Volume = 30*30*30 = 27000 cm^3
density = 2.8 g/cm^3
mass = 27000*2.8 = 75600g = 75.6 kg
Answer:
(a) Region of higher potential
(b) ΔV=1.911V
Explanation:
For Part (a)
Proton moves into a region of higher potential because it must goes in opposite direction of force to get rest
For Part (b)
Potential difference we can calculate bu definition of kinetic energy
ΔK=mv²/2= -qΔV
express in ΔV
ΔV= -mv²/2q
Substitute the given values
So
ΔV= -mv²/2q
ΔV=1.911V
mass times specific heat times tem change.

Electromagnetic wave bc I studied that early in the year
Answer:
D) Grounding
Explanation:
The potential difference between cloud and ground leads to ionization of the atmosphere and resulting conduction through the air often to ground (although it can be between clouds at different potentials. I would say grounding, like the spark when you touch a hot battery terminal to ground on a car.
