Answer:
0.044 seconds
Explanation:
Parameters given:
Length of nerve cell = 1.2m
Nerve impulse speed = 27m/s
Speed is given as:
Speed = distance/time
Therefore, we can make time the subject of the formula. We have:
Time = distance/speed
Hence, time taken for the nerve cell to travel this distance is:
Time = 1.2 / 27
Time = 0.044 seconds
It takes 0.044 seconds for the nerve signal to travel the distance of the nerve connecting the spinal cord to the feet.
b. solar flares
c. coronas
d. supernovae
Answer: Solar Flares
Explanation:
The first thing we must do for this case is to define a frame of reference.
We know that, the frame of reference for this case is Alana.
Therefore, the tennis ball has a speed relative to Alana.
The speed relative to Alana, is the same speed with which Alana throws the tennis ball.
Therefore, the speed of the tennis ball is:
v = 11 Km/h
Answer:
The speed of the tennis ball is:
v = 11 Km/h
a.0.890hertz
b.100hertz
c.230hertz
d.733
1. The wavelength is the ratio of the wave's speed to its frequency in hertz or 1/s. This is shown below,
λ = s / f = (320 m/s) / (300 1/s) = 1.07 m
The wavelength is approximately 1.07 m.
2. The frequency is the ratio between speed and the wavelength,
f = (330 m/s) / 0.45 m = 733.33 hertz
