Einstein's theory determined that the laws of physics are the same for all non-accelerating observers, and he showed that the speed of light within a vacuum is the same no matter the speed at which an observer travels.

The speed of sound is measured to be 340 m/s on a certain day.
ziro4ka [17]
Answer: 1,224 km/h

Explanation:

To do this, we pick the first unit and convert
Picking m first and converting to km:
Since we're converting from a non-prefix to a prefix, we divide the value by the prefix were taking it to. In this case, kilo = 10³ which means we're going to divide our value by 1000 to convert it from m to km
340 m/s ÷ 1000 = 0.34 km/s
Now, let's convert our seconds to hour:
We'll need to calculate how many hours is equivalent to one second first;
1 hr = 60×60 seconds
X hr = 1 second
*Cross multiply*
1 × 1 = X × 60 × 60
1 = 3,600 X
X = 1 / 3,600
X = 2.778×10⁻⁴ hour
So, in the place of "1 Second", we're going to be inserting 2.778×10⁻⁴ hour instead
0.34 km / s = 0.34 km / 2.778×10⁻⁴ hour
(0.34 / 2.778×10⁻⁴) km/hour
1,224 km/h.
340 m/s = 1,224 km/h

A milliammeter has an internal resistance of 5ohms and
Vikentia [17]

Answer:

Rs = 0.02008 Ω = 20.08 mΩ

Explanation:

The range of an ammeter can be increased by connecting a small shunt resistance to it in a series combination. This shunt resistance can be calculated by the following formula:

Rs = \frac{I_gR_g}{I - I_g}

where,

R_s = value of shunt resistance = ?

I_g = current range of ammeter = 20 mA = 0.02 A

I = Required range of ammeter = 5 A

R_g = Resistance of ammeter = 5 ohms

Therefore,

R_s = \frac{(0.02\ A)(5\ ohms)}{5\ A-0.02\ A}

<u>Rs = 0.02008 Ω = 20.08 mΩ</u>

Some scientists speculate that our universe is not the only universe that exists, but the only one we can gather evidence about.
o-na [289]

This idea is called the multiverse theory

<h3>What is the Multiverse theory?</h3>

According to multiverse hypothesis, our universe, which spans tens of billions of light-years and contains hundreds of billions of galaxies and almost innumerable stars, may not be the only one. Instead, there may be a whole distinct world, far away from ours, and then another, and another. In fact, there may be an infinite number of universes, each with its own set of physical laws, stars and galaxies (if they can exist in those worlds), and perhaps even sentient civilizations.

The idea of the multiverse appears in a few branches of physics (and philosophy), but inflation theory provides the best-known example. According to inflation theory, a hypothetical occurrence took place when our universe was really young—less than a second old. According to NASA, the cosmos had a brief period of fast expansion before "inflating" to become several orders of magnitude larger than it had been.

According to Heling Deng, a cosmologist at Arizona State University and an authority on the multiverse hypothesis, the expansion of our universe is assumed to have stopped some 14 billion years ago. However, Deng noted in an email to Live Science, "inflation does not disappear everywhere at the same time." It's possible that if inflation slows down in one area, it picks up in another.
