The car's kinetic energy is
KE = (1/2) (mass) (speed)² .
We notice that the speed is squared in the formula for KE,
so the KE varies as the square of the speed.
If the speed changes from 20mph to 60mph, it has tripled.
So the KE increases by a factor of (3²) = 9 times the original KE.
Answer:
Fluorine and sodium
Explanation:
Fluorine has 2,7 remaining one valance electron to be balance and sodium has 2,9 in which it will lose one too for both of them to be balanced so fluorine atom will receive 1 valence electron from sodium atom so they can both be balanced
The cause of the beats is that t<span>he two waves produced have different frequencies. The frequencies will result to the different energy to be emitted causing it to have beats or sound. The higher the frequency, the higher the pitch and vice versa.</span>
