Why can't you hear a sound in space ?

The electric current amount will vary according to the resistance value when connected to a voltage of a power supply. If resistance is reduced, current will increase. So, if the resistance is infinite (open circuit), the current could be considered zero, or infinitesimal small, if the resistance is zero (of infinitesimal small), the current will tend to be the maximum the power supply can provide. Here is the case of the power supply capability, input resistance, capacity to hold and regulate the output voltage to a certain maximum current, etc. Normally when you short circuit (zero ohms resi

Answer:

x = 5

y = 3

Explanation:

x + y = 8 and 3x + 2y = 21

Here We use Substitution Method

x + y = 8 ...(1)

3x + 2y = 21 ...(2)

From equation (1) we get

x + y = 8

x = 8 - y

Now the value of x = 8 - y in equation (2)

3(8 - y) + 2y = 21

24 - 3y + 2y = 21

- y = 21 - 24

y = 3

Then Put the value of y in equation (1)

x + (3) = 8

x + 3 = 8

x = 8 - 3

x = 5

Thus The value of x is 5 and y is 3

x + y = 8

5 + 3 = 8

8 = 8

3x + 2y = 21

3(5) + 2(3) = 21

15 + 6 = 21

21 = 21

Answer:

You will hear the note E₆

Explanation:

We know that:

Your speed = 88m/s

Original frequency = 1,046 Hz

Sound speed = 340 m/s

The Doppler effect says that:

[tex]f' = \frac{v \pm v0 }{v \mp vs}*f[/tex]

Where:

f = original frequency

f' = new frequency

v = velocity of the sound wave

v0 = your velocity

vs = velocity of the source, in this case, the source is the diva, we assume that she does not move, so vs = 0.

Replacing the values that we know in the equation we have:

[tex]f' = \frac{340 m/s + 88m/s}{340 m/s} *1,046 Hz = 1,316.73 Hz[/tex]

This frequency is close to the note E₆ (1,318.5 Hz)

A) Armstrong is not a unit of pressure. In fact, I don't think it's even a unit at all, an "Amstrong" is a unit of length, if that's what you meant.

Answer: Thunderstorm.

Explanation: When a cold, dry air mass collides with a warm, humid air mass over the land, that's a tornado, but on top of that the air rises and it cools and condenses that's a thunderstorm

When a cold, dry air mass collides with a warm, humid air mass over the land, that's a tornado, but on top of that the air rises and it cools and condenses that's a thunderstorm.

A thunderstorm, sometimes referred to as an electrical storm or a lightning storm, is a type of storm that is distinguished by the presence of lightning and the thunder that results from the lightning's acoustic effect on the Earth's atmosphere.  

Thundershowers are the name for relatively weak thunderstorms. A cumulonimbus is a form of cloud where thunderstorms develop.  They frequently produce heavy rain.  and occasionally snow, sleet, or hail and they are typically accompanied by strong wind.

However, some thunderstorms result in little or no precipitation. A squall line, often known as a succession of thunderstorms, can form or become a rainband.

Therefore, When a cold, dry air mass collides with a warm, humid air mass over the land, that's a tornado, but on top of that the air rises and it cools and condenses that's a thunderstorm.

Answer:

the point the mass of an object will increase when traveling at relativistic speeds

Explanation:

m = m0/((1 - v2/c2))1/2

m0 = the mass measured at rest relative

m = the mass measured by the observers on the other reference frame.

v = the speed of the object

c = the speed of light in a vacuum

Explanation:

Given that,

The pilot directs the aircraft to fly due north at 600km/h.

A side-wind blows at  100km/h towards the east.

We need to find the aircraft's resultant velocity. et it be v. It can be calculated as follows :

[tex]v=\sqrt{600^2+100^2} \\\\v=608.27\ m/s[/tex]

For direction,

[tex]\tan\theta=\dfrac{600}{100}\\\\\tan\theta=6\\\\\theta=\tan^{-1}(6)\\\\\theta=80.53^{\circ}[/tex]

So, the aircraft's resultant velocity is 608.27 km/h and it is at and angle of 80.53°.
