It is called a warm front when a warm air mass moves into an area where a cold air mass is located based on the blanked sentence above. A warm front is a condition where a warm air mass is replacing a cold air in a place. The character of a warm front condition is an increasing in temperature of a place which is caused by the moving warm air mass<span>.</span>
Answer:
![\Delta p=4000.4199\ Pa](https://tex.z-dn.net/?f=%5CDelta%20p%3D4000.4199%5C%20Pa)
Explanation:
Given:
- difference in the column of mercury of u-tube manometer,
![\Delta h=3\ cm=0.03\ m](https://tex.z-dn.net/?f=%5CDelta%20h%3D3%5C%20cm%3D0.03%5C%20m)
<u>We know that the pressure due to height if a liquid column is given as:</u>
![p=\rho.g.h](https://tex.z-dn.net/?f=p%3D%5Crho.g.h)
where:
p = pressure
h = height of the liquid
density of the liquid
- We have the density of mercury as,
![\rho=13593\ kg.m^{-3}](https://tex.z-dn.net/?f=%5Crho%3D13593%5C%20kg.m%5E%7B-3%7D)
<u>Now the difference of pressure in the two tubes of the manometer:</u>
![\Delta p=\rho.g.\Delta h](https://tex.z-dn.net/?f=%5CDelta%20p%3D%5Crho.g.%5CDelta%20h)
![\Delta p=13593\times9.81\times0.03](https://tex.z-dn.net/?f=%5CDelta%20p%3D13593%5Ctimes9.81%5Ctimes0.03)
![\Delta p=4000.4199\ Pa](https://tex.z-dn.net/?f=%5CDelta%20p%3D4000.4199%5C%20Pa)
Answer:
The answer is "Choice E".
Explanation:
In this situation the option e is right because its resistance decreases through time, however, the time is the same for the same reason, whereas the sphere deteriorates, somehow it travels shorter distances however if the air resistance becomes are using the amplitude of movement declines, that's why other choices were wrong.
Answer:
A) Change in momentum remains unchanged
B) Impulse remains unchanged
C) Average force decreases 10 times
Explanation:
A) The presence of snow does not change the momentum because the initial momentum is the same as final momentum.
B) impulse is equal to change in momentum. Since the presence of snow doesn't affect the change in momentum, it doesn't also affect the impulse.
C) The presence of snow would cause a decrease in average force stopping the paratrooper because since impulse is unchanged and Δt increased 10 times, then the
force must decrease 10times.
