Answer:

B. Increasing temperature.

Explanation:

Atmospheric pressure increases with increasing temperature because warm air causes the atmospheric pressure to rise.

Basically, when the molecules contained in air experience a collision, they usually exert forces on one other, and when these molecules become heated, they experience a quick and rapid motion leading to an increased rate of collision. Therefore, as more force is being exerted on the air molecules, the atmospheric pressure tends to rise or increase.

Definition of continental polar

kipiarov [429]

Answer:

Continental polar (cP) or continental arctic (cA) air masses are cold, dry, and stable. These air masses originate over northern Canada and Alaska as a result of radiational cooling. Maritime polar (mP) air masses are cool, moist, and unstable.

Please help !!! A 12 V battery is set up in an unknown configuration. The internal resistance of the battery is 4 Ohms. If this

Delvig [45]

Answer:

Explanation:

Given that,

Battery capacity

E=12V

Internal resistance of battery r=4ohms

We are told that the circuit must have at least 2 resistor

If the terminal voltage is Vt= 11.478V

Let all the resistor we want to connect the battery have a equivalent resistance Req

Req = R1 +R2 + R3+...+ Rn

Series connection

Using KVL in the circuit,

E = I(R+r)

12 = I ( Req + 4) equation 1

When the terminal voltage is 11.478V, I.e voltage across the external resistance, in this case the equivalent resistance Req

Using ohms law

Vt=I•Req

Then,

11.478 = I•Req equation 2

Make I subject of formulae

Then, I = 11.478/Req. Equation 3

Substitute equation 3 into 1

12 = I ( Req + 4)

12 = 11.478/Req ( Rea + 4)

12 = 11.478 + 45.912/Req

12 - 11.478 = 45.912/Req

0.522 = 45.912/Req

Cross mutilply

0.522 Req = 45.912

Then, Req = 45.912/0.522

Req = 87.95 ohms

Req ≈ 88 ohms

The resistor must have a resistance of 88 ohms and they have a series configuration

kozerog [31]

Answer:

False

Explanation:

Though fiber active cable is based on the concept of internal reflection but it is achieved by refractive index which transmit data through fast traveling pulses of light. It has a layer of glass and insulating casing called “cladding,”and this is is wrapped around the central fiber thereby causing light to continuously bounce back from the walls of the Cable.
