The frequency of a sound is whatever frequency leaves the source. It doesn't change.
Voiced of swimmers at the pool don't change frequency in or out of the water. Only their speed and wavelength change.
Answer:
The identity of an element depends on the number of protons, neutrons, and electrons.
Explanation:
The activity occurring at an axon terminal involves the following labelled 1 - 6:
- synaptic vesicles
- synapse
- motor end plates (neurotransmitter receptor)
- calcium channel
- neurotransmitters
- axon
The transmission of nerve impulses between neurons, muscles cells or glands is known as nervous transmissions.
Axons are long slender projections of neurons which are responsible for nervous transmission.
Neurons use both electrochemical signals and chemicals known as neurotransmitters to transmit impulses from one neuron to the next.
The junction between two neurons or an effector cell is known as a synapse.
Neurotransmitters are packaged into synaptic vesicles at the axon end. When electrical signal reaches the end of the axon, influx of calcium ions through the calcium channel cause the the synaptic vessels to fuse with the presynaptic membrane and then release their contents into the synaptic cleft or space.
The neurotransmitters released then bind to the motor end plate resulting in another impulse transmission along the second neuron or an action by effector cells.

Answer: The drag force goes up by a factor of 4
Explanation:
The <u>Drag Force</u> equation is:
(1)
Where:
is the Drag Force
is the Drag coefficient, which depends on the material
is the density of the fluid where the bicycle is moving (<u>air in this case)
</u>
is the transversal area of the body or object
the bicycle's velocity
Now, if we assume , and do not change, we can rewrite (1) as:
(2)
Where groups all these coefficients.
So, if we have a new velocity , which is the double of the former velocity:
(3)
Equation (2) is written as:
(4)
Comparing (2) and (4) we can conclude<u> the Drag force is four times greater when the speed is doubled.</u>
You expend 1000 w of power moving a piano 10 meters in 5 seconds. how much force do you exert a. 50 n b. 50000 n c.250 n d. 500 n apex please
<em>P = W/t = (Fxd)/t and rearranging and solving for F, F = (Pxt) / d = (1000x5)/10 = 500 N, choice C.</em>
