Needs work. 100kmph is not a velocity. Deceleration is not sudden. There is no such thing as the "speed" of deceleration. 10 kmph is not a deceleration. And if it were, we would need to know HOW LONG it decelerated. Otherwise an engaging and intriguing question.

KonstantinChe [14]

Answer:

2.145×10^-10 V or 0.2145nV

Explanation:

From hf=eV

h= Plank's constant = 6.6×10^-34JS

f= frequency of the electromagnetic wave = 5.2×10^4 Hz

e= electronic charge= 1.6×10^-19 C

V= voltage

V= hf/e

V= 6.6×10^-34JS × 5.2×10^4 Hz/ 1.6×10^-19 C

V= 2.145×10^-10 V or 0.2145nV

Therefore the voltage created is 2.145×10^-10 V or 0.2145nV

A neutral atom of sodium has 12 neutrons and 11 protons. How many electrons does this sodium have? a.1 b.11 c.12 d.23
Alex Ar [27]

Answer:

We know that the atomic number of sodium is 11. This tells us that sodium has 11 protons and because it is neutral it has 11 electrons. The mass number of an element tells us the number of protons AND neutrons in an atom (the two particles that have a measurable mass)
