Hello, Kaypau3969

A gamma ray is a strong energy ray that has nothing no charge neither mass.

Answer:

Hello, how's your day going?

if humanity came together and made a base on the moon, it would be revolutionary. The point of a base on the moon would have multiple purposes. for example, some think that the moon contains valuable metals such as iron and titanium. a base would serve as a place for workers harvesting metals to rest. Obviously or not most of the iron harvesting would be done automatically by robots and such.

If such a base were constructed on the moon, it would be the begining of people living on other worlds and would be a great start for a base on Mars.

Hope it helped

Certain x-rays have a frequency of 1.0×1019hz. calculate their wavelength in air.
Murljashka [212]
For any electromagnetic wave, the relationship between frequency and wavelength is given by
\lambda =  \frac{c}{f}
where
\lambda is the wavelength
c is the speed of light (the speed of the electromagnetic wave)
f is the frequency

For the X-rays in our problem, the frequency is f=1.0 \cdot 10^{19}Hz, while the speed of light is c=3.0 \cdot 10^8 m/s, so the wavelength of this radiation is
\lambda= \frac{3 \cdot 10^8 m/s}{1.0 \cdot 10^{19} Hz} =3 \cdot 10^{-11} m

The potential (relative to infinity) at the midpoint of a square is 3.0 V when a point charge of +Q is located at one of the cor
WINSTONCH [101]

Answer:

option d) 12.0 V

Explanation:

Data provided in the question:

Potential difference due to a single charge (+Q), E = 3.0 V

Now,

The Electric potential for the system of charges is given as:

E=\frac{1}{4\pi \epsilon_o}[\Sigma\frac{Q}{r}]

given for single charge, E = 3.0 V =  \frac{1}{4\pi \epsilon_o}[\frac{Q}{r}]               .......(1)

so thus, for 4 charges, we have

E=\frac{1}{4\pi \epsilon_o}[4\frac{Q}{r}]      ...............(2)

from 1 and 2 we have

E = 4 × 3.0 V = 12 V

Hence, option d) 12 V is the correct answer.

How can motion be described and measured
PolarNik [594]

Answer:

Motion can be described  "...in terms of displacement, distance, velocity, acceleration, speed, and time," according to Wikipedia. The main feature that measures motion is momentum or speed.

Hope this helped! Let me know if you have any other questions. :)

Suppose that volumes of four stars in the Milky Way are 2.7 x 1018 km3, 6.9 x 1012 km3, 2.2 x 1012 km3, and 4.9 x 1021 km3. What
Irina18 [472]

Answer:

The order is Star 3 < Star 2 < Star 1 < Star 4

Explanation:

Lets name the stars with their written order.

Star 1: 2.7 x 10^18 km3

Star 2: 6.9 x 10^12 km3

Star 3: 2.2 x 10^12 km3

Star 4: 4.9 x 10^21 km3

Star with lowest power of 10 has the least volume. Therefore, star 2 and star 3 would be the stars with least volume. Star 2's coefficient is better than Star 3. Thus, the order will be Star 3 < Star 2 < Star 1 < Star 4.
