Answer:
The current in the second wire is 4.4 A.
Explanation:
Given that,
Distance =7.0 cm
Current in first wire = 2.0 A
The magnetic field strength is zero at distance of 2.2 cm from the first wire.
We need to calculate the current in the second wire
Using formula of magnetic field
Here, 
Put the value into the formula
Hence, The current in the second wire is 4.4 A.
The test tube that first stops in bubbling or the production of a gas is the tube that contains the catalyst since the reaction ended faster than the others. A catalyst is known to speed up a reaction so it must the situation aforementioned is the answer.
Answer:
Using two to three sentences, summarize what you investigated and observed in this lab. I investigated that Most of my planets and moons had the element carbon in them. I observed that Different elements absorb different wavelengths of light.
Astronomers use a wide variety of technology to explore space and the electromagnetic spectrum; why do you believe it is essential to use many types of equipment when studying space?
It is essential to use a number of telescopes sensitive to different parts of the electromagnetic spectrum to study objects in space. Even though all light is fundamentally the same thing, the way that astronomers observe light depends on the portion of the spectrum they wish to study. Tools are useful, such as detectors that help see the different wavelengths of light. Not all light can get through the Earth's atmosphere, so for some wavelengths we have to use telescopes aboard satellites.
If carbon was the most common element found in the moons and planets, what element is missing that would make them similar to Earth? Explain why. (Hint: Think about the carbon cycle.)
The missing element that would make moons and other planets similar to earth is oxygen. The two make carbon dioxide.
We know that the electromagnetic spectrum uses wavelengths and frequencies to determine a lot about outer space. How does it help us find out the make-up of stars?
electromagnetic radiation Explanation, astronomers observe the wavelengths by putting telescopes on mountain tops and take results of what they are seeing
Why might it be useful to determine the elements that a planet or moon is made up of?
It might be useful so we can make new discoveries of life or even plants on other planets and moons. And discover maybe even more moons one other planets.
Hope this helps!!!!
Explanation:
Answer:
Keep alpha in hand, keep beta in pocket, dispose of gamma radioactive sample
Explanation:
<u>Alpha particles:
</u>
Alpha particles are the particles which cannot penetrate most of the matter. The outer layer of the skin or a piece of paper may be sufficient to stop the alpha particles.
The Radioactive material that emits the alpha particles can be harmful when they are swallowed, inhaled, or absorbed into blood stream through wounds.
<u>Thus, α radioactive sample can be kept in hand.</u>
<u>Beta particles:
</u>
Beta particles are the particles which can be stopped by a few mm of a substance like aluminum layer or by clothing.
Beta particles can penetrate the skin and can cause radiation damage, such as skin burns.
<u>Thus, β radioactive sample can be kept in pocket.</u>
<u>Gamma rays:
</u>
Gamma rays are the rays which are penetrating. Many feet of concreted layers or some inches of metal lead are needed to stop them.
Gamma rays are the radiation hazard for the entire human body.
They attack the DNA and can cause lethal defects.
<u>Thus, γ radioactive sample is to be disposed off.</u>
Answer:
The effect of gravity on object makes objects stable and not floating in the air . It also makes any object thrown up to return back
