<u>Question:</u>

Which of the following is not true of the wind?

A) It is initiated by the pressure gradient force.

B) It blows from regions of high pressure to regions of low pressure.

C) The direction of flow can be affected by the rotation of the Earth.

D) Air blows from regions of hotter air to regions of colder air.

E) Winds are named based on the direction from which they blow.

<u>Answer:</u>

The given statement "Air blows from regions of hotter air to regions of colder air" is not true of the wind.

Answer: Option D

<u>Explanation:</u>

The wind is the form of energy transfer in a wave when there is a change in the pressure gradient force. So, the air molecules in the atmosphere will be exhibiting a different gradient force leading to their movement as the wind. As the air molecules present in higher density at high pressure will tend to release its energy by spreading themselves leading to low pressure.

And thus, the wind will be blowing from regions of high pressure to regions of low pressure. Mostly the winds are named based on the direction of their flow or blow and their direction gets affected by the rotation of the earth. So the only option that is air blows from regions of hotter air to regions of colder air is not true for wind.

Hicham El Guerrouj of Morocco holds the world record in the 1500 m running race. He ran the final 400 m in a time of 51.9 s.
konstantin123 [22]

Answer: His average speed in mph over the last 400 m is 7.7 m/s.

Explanation:

Given: Hicham El Guerrouj of Morocco holds the world record in the 1500 m running race. He ran the final 400 m in a time of 51.9 s.

We know that , speed = \dfrac{distance}{time}

Here , distance = 400m and time = 51.9 s

Then, speed =  \dfrac{400}{51.9}\approx7.7\ m/s

Hence, his average speed in mph over the last 400 m is 7.7 m/s.

A thin stream of water flows smoothly from a faucet and falls straight down. at one point the water is flowing at a speed of v1
kati45 [8]
<span>The formulas are, v1d1² = v2d2² ........ (1) h = (v2²-v1²)/2g ...... (2) Given that, v1 = 1.71 m/s we assume that the stream has decreased by a factor d2 =0.805d1 then, v1d1² = v2 (0.805d1)² cancelled both side d1² then we get, v1 = v2 (0.805)² v1 = v2 (0.648025) Sub v1 = 1.71, 1.71 = v2 (0.648025) v2 = 1.71/0.648025 v2 = 2.638787083831642 v2 = 2.64 m/s The vertical distance formula, h = (v2²-v1²)/2g We know that value of gravity constant is 9.8 m/s² h = {(2.64)² - (1.71)²)/2(9.8) h = {(6.9696) - (2.9241)}/19.6 h = (4.0455)/19.6 h = 0.2064030612244898 h = 0.21 cm Therefore, the vertical distance h = 0.21 cm.</span>

If the envelope and gondola have a total mass of 4300 kg, what is the maximum cargo load when the blimp flies at a sea-level loc
geniusboy [140]

Complete question:

The classic Goodyear blimp is essentially a helium balloon— a big one, containing 5700 m³ of helium. If the envelope and gondola have a total mass of 4300 kg, what is the maximum cargo load when the blimp flies at a sea-level location? Assume an air temperature of 20°C.

Answer:

52.4 kN

Explanation:

The helium at 20°C has a density of 0.183 kg/m³, and the cargo load is the weight of the system, which consists of the envelope, the gondola, and the helium.

The helium mass is the volume multiplied by the density, thus:

mHe = 5700 * 0.183 = 1043.1 kg

The total mass is then 5343.1 kg. The weight is the mass multiplied by the gravity acceleration (9.8 m/s²), so:

W = 5343.1*9.8

W = 53362.38 N

W = 52.4 kN
