Describe how wet and dry barometers work

Physics
1 answer:
siniylev [52]3 years ago
7 0

Answer: Wet barometer - The tool works by measuring atmospheric pressure to predict incoming weather. Since the glass is only filled halfway with water, the other half is exposed to the atmosphere. When the outdoor atmospheric pressure rises, the pressure in the glass decreases, and causes the water to move down the spout.

Dry barometer - A Torricellian barometer (sometimes called a mercury barometer) is an inverted (upside-down) glass tube standing in a bath of mercury. Air pressure pushes down on the surface of the mercury, making some rise up the tube. The greater the air pressure, the higher the mercury rises.

I hope this helps!

jeka94
We are given the following:
thickness, T = 0.155 mm
charge-carrier density, n = 1.05 x 10^25 / m3
current, I = 2.67 A
voltage, V = 4.89 mV

We are asked to get the magnetic strength, B

To solve this, we use the Hall Effect formula:
V = - IB / neT
where e is the charge of an electron which is e = 1.60 x 10^-19 and B is the magnetic field
Rearranging the formula
B = -V n e T / I
Substituting the given values
B = - (4.89 x 10^-3 V) (1.05 x 10^25 / m3) (0.155 x 10^-3 m) / 2.67 A
B = -2.98 x 10^18 Teslas

Alexxx [7]

Answer:

165.529454

Explanation:

According to the Pythagorean Theorem for calculating the lengths of a right angle triangle's sides, a^2 + b+2 = c^2, where c is the longest side (and the side opposing the right angle). So in your case it would be 150*150 + 70*70 = 27400. And √ 27400 is your answer.

At 96° F the saturation density of air is 0.04 kg/m3. If the weather report says the relative humidity is 90 % when the tempera
nalin [4]

Answer:

The value is  H  =  0.036 \ kg/m^3

Explanation:

From the question we are told that

   The saturation density of air is \rho =  0.04 \ kg/m^3

   The temperature for this saturation density to occur  T_s  =  96^o F

    The relative humidity at this temperature is  R_h  =  90\%  =  0.90

Generally the relative humidity is mathematically represented as

      R_H  = \frac{H}{\rho}

Here H represents humidity

=> 0.90 =  \frac{H}{0.04}

=>  H  =  0.90 * 0.04

=>  H  =  0.036 \ kg/m^3
