Answer:
C. There is a net horizontal force on the skier in the direction the boat’s velocity.
Explanation:
This is because, according to Newton's First law of motion, when an object which in this case is the skier tends to be in equilibrium because it travels at a constant velocity, there is no net acceleration of the skier, and this causes the net force on the skier to be equal to zero.
Therefore in this question, option C which states that "There is a net horizontal force on the skier in the direction the boat’s velocity" is a false statement.
My guesses would be g. or F
Answer:
The diameter is 0.000056 m
Explanation:
Lets explain the relation between the meter and the micrometer
1 Meter is equal to 1000000 (one million) micrometers
1 micrometer = 
The symbol of the meter is m
The symbol of micrometer is μm
A human hair is approximately 56 µm in diameter
We need to express this diameter in meter
To do that we divide this number by 1,000,000 or multiply it by 
→ 
56 µm = 0.000056 m
→ OR
→ 
→ 56 µm = 0.000056 m
<em>The diameter is 0.000056 m</em>
Answer:
(C) The frequency decrease and intensity decrease
Explanation:
The Doppler effect describes the change in frequency or wavelength of a wave in relation to an observer who is moving relative to the wave source, or the wave source is moving relative to the observer, or both.
if the observer and the source move away from each other as is the case for this problem, the wavelength heard by the observer is bigger.
The frequency is the inverse from the wavelength, so the frequency heard will increase.
The sound intensity depends inversely on the area in which the sound propagates. When the buzzer is close, the area is from a small sphere, but as the buzzer moves further away, the wave area will be from a larger sphere and therefore the intensity will decrease.
Answer:
Other movements are involuntary meaning they are not under conscious control such as the contraction of your pupil in bright light muscle tissue is classified into three types according to structure and function skeletal cardiac and smooth
