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
is equal to its final horizontal velocity
bez both upward and downward motions are identical in presence of single force called gravitational force which acts in y axis direction and horizontal velocity is in x axis so net force on horizontal velocity is zero
Answer:
moving at a constant rate. (could be zero m/s)
Answer:
A. 70 m OS the correct one
First we have to establish that the number of protons is equivalent to the atomic number of element. Here I am assuming that you are referring to Potassium (K) - 40. Potassium, stable or unstable has 19 protons.
