Answer:
efferent pathway
Explanation:
efferent pathway - it is the pathway used by signal to get away from the nervous system. After getting signal from the brain, efferent signal direct body to do according to the received signals.
while on the other side, afferent signals related to the signal that sends by the body to the brain. which is opposite to the efferent signals
Impulse = Force * times and also Impulse = change in momentum.
Given that the mass does not change, change if momentum = mass * (final velocity - initial velocity)
Given that you know mass and initial velocity (which is the velicity before the cart hits the wall) you need the final velocity (which is the velocity after the cart hits the wall).
Answer: the velocity of the cart after it hits the wall.
The frequency of any wave is (speed) / (wavelength).
Frequency = (330 m/s) / (2m) = 165 per second = <em>165 Hz</em>.
Period = 1 / frequency = 1 / (165 per second) = <em>0.0061 second </em>
Answer:
you need to know the wave length and frequency
Explanation:
it is because of the formula of the wave speed
I think its between b or c
