Many gases are shipped in high-pressure containers. Consider a steel tank whose volume is 55.0 gallons and which contains O2 gas

at a pressure of 16,500 kPa at 23 degrees C.. . What is the mass of O2 in the tank in g?. . What volume would the gas occupy at STP in liters?. . At what temperature would the pressure in tank equal 1.55 atm?. . What would be the pressure of the gas, in kPA, if it were transferred to a container at 24 degrees C, whose volume is 55.0 L ?

We are given with conditions on temperature, pressure and volume of gas. In this problem, we apply ideal gas law PV = nRT to solve what are asked.

1. PV = nRT ; n = m/MM
    16.5 x10^6 Pa * 0.003785 m3= n * 8.314 Pa m^3/ mol K * (23+273) K 
    n = 25.38 mol; mass = 812.08 grams. 
2. V at STP is 22.4 L/mol
3. PV = nRT = 1.5 atm *  0.003785 *1000 L = <span>25.38 mol * 0.0821 L atm/mol K * T ; T = 2.72 K
4. P * 55 m3/1000 = 25.38 mol * </span><span>8.314 Pa m^3/ mol K</span><span> * (24+273) K
  P = 1139. 45 kPa</span>

Two parallel wires are separated by 6.10 cm, each carrying 2.85 A of current in the same direction. (a) What is the magnitude of
Westkost [7]

Answer:

The force per unit length is 2.66 \times 10^{-5} \ N/m

Explanation:

The current carrying by each wires = 2.85 A

The current in both wires flows in same direction.

The gap between the wires = 6.10 cm

Now we will use the below expression for the force per unit length. Moreover, before using the below formula we have to change the unit centimetre into meter. So, we just divide the centimetre with 100.

F/l = \frac{\mu _0i_1 i_2}{2\pi d} \\i_1 = 2.85 \\i_ 2 = 2.85  \\\mu _0 = 4\pi \times 10^{-7} \\d = 0.061 \\F/l = \frac{4\pi \times 10^{-7} \times 2.85 \times 2.85}{2 \pi \times 0.061} \\= 2.66 \times 10^{-5} \ N/m

there are two types of waves: electromagnetic and mechanical. can either type travel regardless of the presence of a medium?
Dmitry_Shevchenko [17]

Yes, electromagnetic can travel without medium.

Mechanical waves and electromagnetic waves are two important ways that energy is transported in the world around us.

Waves in water and sound waves in air are two examples of mechanical waves.

Mechanical waves are caused by a disturbance or vibration in matter, whether solid, gas, liquid, or plasma.

Matter that waves are traveling through is called a medium.

These mechanical waves travel through a medium by causing the molecules to bump into each other, like falling dominoes transferring energy from one to the next.

Sound waves cannot travel in the vacuum of space because there is no medium to transmit these mechanical waves.

On the other hand electromagnetic waves don't require medium for its propagation.

An easy example would be light which is an EM wave reaches earth even though space has no medium.

A student is wearing a pair of sunglasses designed to reduce the glare from reflected surfaces. When the student tilts her head
agasfer [191]
The answer is polarization. It is just like when you are on a boat and use polarized glasses so the water wont reflect into your eyes it also intensifies the color of the water so you can see better into the water.
example: you cant see any fish because glare from the sun, put on polarized glasses and now you can see fish up to 30 feet deep.
