The frequency of an x-ray wave is 3 Hz and its wave speed is 90 m/s. What is the x-rays wavelength?

Answers

The frequency is
=
2⋅10^18 Hz
Solution:
Frequency (f) = 3Hx
Wave speed ( v) = 90m/s
Wavelength. = ?
We know ,
v = frequency . Wavelength
or, 90 = 3 multiply wavelength
or, 90 = 3 wavelength
or, 90/3 = wavelength
or, 30 = wavelength
Wavelength = 30 m

Please help me with this question: What do space probes do in space? Please explain your answer with 5 sentences or more.

Answers

Answer:

Explanation:A space probe is an unpiloted, unmanned device sent to explore space and gather scientific information. A space probe is launched from Earth with a set of scientific instruments and tools used to study the atmosphere and composition of space and other planets, moons, or celestial bodies.

A space probe is a device sent from earth to take in information about the atmosphere and the makeup of space. Not only does it study our atmosphere, but it also studies moons, and/or other celestial bodies. A space probe works by powering on as soon as contact is reached with a component surface. This provides the probe with accurate data. Space probes are able to move in space using either “thrusters” and/or “rotation wheels”.

How does the sun create heat?


When will the sun start losing energy?


How did the sun get created?


EXPLAIN PLEASE !! ILL GIVE BRIANLOUS!!

Answers

Explanation:

sun was created through the hypothesis

Answer;

Answer of Question:1

The core of the sun is so hot and there is so much pressure, nuclear fusion takes place: hydrogen is changed to helium. Nuclear fusion creates heat and photons (light). The sun's surface is about 6,000 Kelvin, which is 10,340 degrees Fahrenheit (5,726 degrees Celsius).

Answer of Question:2

in about 5 billion years, the sun will run out of hydrogen. Our star is currently in the most stable phase of its life cycle and has been since the birth of our solar system, about 4.5 billion years ago. Once all the hydrogen gets used up, the sun will grow out of this stable phase.

Answer of Question:3

Formation. The Sun and the rest of the solar system formed from a giant, rotating cloud of gas and dust called a solar nebula about 4.5 billion years ago. As the nebula collapsed because of its overwhelming gravity, it spun faster and flattened into a disk. ... Like all stars, the Sun will someday run out of energy.
