What would happen if you put bubble wrap around an experiment of heat energy​

Physics
1 answer:
Makovka662 [10]3 years ago
3 0

Answer: The air pressure would build up resulting in a high air density.

Explanation: Heat energy builds up air pressure. And if you surround it with bubble wrap, that air pressure will have nowhere to release to. And so because of that, high air density occurs.

The fine structure for hydrogen atom is
pochemuha

Answer:

When the familiar red spectral line of the hydrogen spectrum is examined at very high resolution, it is found to be a closely-spaced doublet. This splitting is called fine structure and was one of the first experimental evidences for electron spin.

Two resistors ( 3 ohms & 6 ohms) in a series circuit with a power supply = 12 volts. The current through resistor 6 ohms is
Scorpion4ik [409]

In a series circuit . . .

-- The total resistance is the sum of the individual resistors.

-- The current is the same at every point in the circuit.

The total resistance in this circuit is (3Ω + 6Ω )  =  9Ω

The current at every point is (V/R) = (12v / 9Ω ) = <em>1.33 A</em> .

Pick choice<em> (a)</em>.

The fastest helicopter, the Westland Lynx, can travel 3.33 km in the forward direction in just 30.0 s. What is the average veloc
QveST [7]

Answer:

The value in m/s v_{a} =  111 \  m/s

The value in km/h v_{a} = 400\  km/h

Explanation:

Generally the average velocity of the helicopter is mathematically represented as

v_{a} =  \frac{\Delta D}{ t}

substituting 3.33 km = 33.3*10^3\ for\  \Delta D and  30.0 s for  t

We have

         v_{a} =  \frac{33.3 *10^{3}}{ 30}

=>     v_{a} =  111 \  m/s

Now converting to km/h

      v_{a} =  111  *  \frac{3600  *\frac{s}{h} }{1*10^{-3} *\frac{km}{m}}

=>  v_{a} = 400\  km/h
