Answer:

Barometer is used to measure air pressure.

Explanation:

Barometer :

Barometer used to measure the air pressure.

It is the scientific device which is used to measure the atmospheric pressure.

Atmospheric pressure change with the distance above and below the sea level.

When the air pressure is greater, then the mercury rises the higher.

Air pressure :

The weight of the air molecules pressing down on the earth it is called air pressure.

The density of air molecules is higher at sea level where the air pressure will be higher.

ear the end of a marathon race, the first two runners are separated by a distance of 45.0 m. The front runner has a velocity of
sesenic [268]

Answer:

a) V_{2/1}=0.8m/s

b) The second runner will win

c) d = 10.54m

Explanation:

For part (a):

V_{2/1} = V_{2} - V_{1} = 0.8m/s

For part (b) we will calculate the amount of time that takes both runners to cross the finish line:

t_{1} = \frac{X_{1}}{V_{1}}=\frac{250}{3.45}=72.46s

t_{2} = \frac{X_{2}}{V_{2}}=\frac{250+45}{4.25}=69.41s

Since it takes less time to the second runner to cross the finish line, we can say the she won the race.

For part (c), we know how much time it takes the second runner to win, so we just need the position of the first runner in that moment:

X1 = V1*t2 = 239.46m  Since the finish line was 250m away:

d = 250m - 239.46m = 10.54m
