For the sun, which is the final step in core fusion?

1 answer:

3 0

The answer would be stage of<span> conversion of Hydrogen to Helium.
At the end of this phase, the helium content of the suns will have the popping effect where more and more helium is now on the core resulting to higher temp and density as helium converted from hydrogen is much heavier.</span>

Chemical weathering may occur because the mineral or rock is exposed to the air. this reaction occurs naturally with some chemic

aliya0001 [1]

Answer: a. oxidation

Explanation:

The weathering is a process through which the large rocks are broken into small rocks or pieces. The weathering can be caused by the physical and chemical agents.

The chemical weathering is a process in which the rock is disintegrated or broken into sub-components by the action of the chemical agents present in the surrounding of rock for example, air, water, acid, and alkali.

The air will cause the oxidation of the rocks. This will cause weathering of rocks as the oxygen will react with the minerals present in rocks making their bonds weak and causes disintegration of rocks.

7. A neutral aluminum rod is at rest on a foam insulating base. A negatively charged balloon is brought near one end of the rod

WITCHER [35]

Answer:

If a negatively charged balloon is brought near one end of the rod but not in direct contact, then <u>the negative charges on the balloon repel the same amount of negative charges on the end of the rod that is close to the balloon</u>, and the positive charges stay at the balloon-side of the rod. The total charge of the rod is still zero, but the distribution of the charges are now non-uniform.

Two forces P and Q act on an object of mass 15.0 kg with Q being the larger of the two forces. When both forces are directed to

Rom4ik [11]

Answer:

P=6.25N and Q=16.25N

Explanation:

In order to solve this problem we must first draw a free body diagram for both situation, (see attached picture).

Now, we need to analyze the two free body diagrams. So let's analyze the first diagram. Since the body is accelerated, then the sum of forces is equal to mass times acceleration, so we get:

$\Sigma F=ma$

We can assume there will be only the two mentioned forces P and Q, so

the sum of forces will be:

P+Q=ma

$P+Q=(15kg)(1.50m/s^{2})$

P+Q=22.5N

We can do the same analysis for the second free body diagram:

$\Sigma F=ma$

$Q-P=(15kg)(0.7m/s^{2})$

Q-P=10.5N

so now we have a system of equations we can solve by elimination:

Q+P=22.5N

Q-P=10.5N

Now, we can add the two equations together so the P force is eliminated, so we get:

2Q=32.5N

now we can solve for Q:

$Q=\frac{32.5N}{2}$

Q=16.25N

Now we can use any of the equations to find P.

Q+P=22.5N

P=22.5N-Q

when substituting for Q we get:

P=22.5N-16.25N

P=6.25N
