The period is simply the inverse of the frequency, therefore:
T = 1 / f
T = 1 / 775 Hz
T = 0.001290 s → possible answer
T = 1.29 × 10⁻³ s → possible answer
T = 1.29 ms → possible answer
Answer:
Isotopes can both be the same element but have a different number of electrons
Explanation: not sure if more was supposed to be there, but i tried
Answer:
further tightening is required.
Explanation:
The beat created / sec = difference of frequencies
Initial beat heard = 2
so difference of frequencies = 2
after tightening beat heard = 1
difference of frequencies decreases because frequency of tuning fork was higher than piano sound.
on further tightening difference decreases because tightening increases the frequency of piano hence further tightening is required for resonance.
The final answer is B hope its helps
