The proton number?
number of protons
Answer:
its the teal/second from the left one
Explanation:
A vibrating stretched string has nodes or fixed points at each end. The string will vibrate in its fundamental frequency with just one anti node in the middle - this gives half a wave.
Rearranging for the wavelength
Therefore the longest wavelength standing wave that it can support is 14m
Answer:
Explanation:
From Kinetic energy K.E = m*/2
Where mass of the car, m = 850 kg
velocity of the car, v = 18 m/s
Hence K.E =
Also, we can evaluate the given time
time = K.E / Power
=
= 2.87 secs
