Answer:
What is a Pure Substance?
Explanation:
It is something which cannot be divided into parts by physical means, as it's all made up of the same thing. Pure substances are either elements or compounds. Elements can NOT be separated into other types of matter (physically or chemically).
D) sepals
other options are ridiculous
Answer:
3.63 s
Explanation:
We can solve the problem by using the equivalent SUVAT equations for the angular motion.
To find the angular acceleration, we can use the following equation:
where
is the final angular speed
is the initial angular speed
is the angular distance covered
is the angular acceleration
Re-arranging the formula, we can find :
Now we want to know the time the bit takes starting from rest to reach a speed of . So, we can use the following equation:
where:
is the angular acceleration
is the final speed
is the initial speed
t is the time
Re-arranging the equation, we can find the time:
The correct answer is
- +6q is the charge induced on the interior surface
- -6q is the charge induced on the exterior surface
A uniformly distributed negatively charged -q will be induced on the cavity's inner surface and a positively charged +q on its outer surface. Due to inner charges +q and -q, point P will not have a field or potential. Only the outer +q charge will be responsible for P's potential.
An atom is said to be electrically neutral when its total charge is zero. Protons, which are positively charged, electrons, which are negatively charged, and neutrons, which are not positively or negatively charged, make up an atom. An atom will be electrically neutral if it has an equal amount of protons and electrons since the charge from each particle is of equal intensity. Electrical neutrality is the absence of any net electrical charge. An atom will be electrically neutral if it has an equal amount of protons and electrons since the charge from each particle is of equal intensity.

Complete question:
Suppose a charge -6q is suspended inside a cavity in an electrically neutral cylindrical conductor. What is the charge induced on the exterior surface?
Is earth’s freshwater
Only about 3 percent of Earth’s water is fresh water.
