How does the mass of an object affect its acceleration during free fall

2 answers:

The mass of an object has no effect whatsoever on the object's
acceleration during free-fall. If there is no air resistance to interfere
with the natural effects of gravity, then a feather and a battleship ...
dropped at the same time ... fall together, and hit the ground at the
same time.

It doesn't. If you took a watermelon and an orange and dropped them at the same time, they would fall the same speed snd land (or squash) at the same time. Try it. It doesn' have to be those two fruits.

Which is considered a high-priority health issue in the United State?

Mamont248 [21]

Hello!

I believe C) immunizations are a high-priority health in the United States. First let's talk about what immunizations are. Immunizations are a liquid that is injected into your body by needle. This liquid then enters your blood stream and it gets pumped into all of your body because of your circulatory system. So it spreads all around your body and when you get sick, that vaccine helps to get rid of the disease way quicker or even not at all. The U.S government are in high demand to prevent serious disease by giving people the vaccines because many people are getting sick from, for instance, cancer. Although the actually vaccine cannot cure cancer it can prevent it from happening.

I hope it helps!

The mass of a glass beaker is known to be 24.2 g. Approximately 5 mL of water are added, and the mass of the beaker and water is

Kamila [148]

Answer: 2 significant figures in 6.4

Explanation:

Significant figures : The figures in a number which express the value -the magnitude of a quantity to a specific degree of accuracy is known as significant digits.

Rules for significant figures:

Digits from 1 to 9 are always significant and have infinite number of significant figures.

All non-zero numbers are always significant. For example: 654, 6.54 and 65.4 all have three significant figures.

All zero’s between integers are always significant. For example: 5005, 5.005 and 50.05 all have four significant figures.

All zero’s preceding the first integers are never significant. For example: 0.0078 has two significant figures.

All zero’s after the decimal point are always significant. For example: 4.500, 45.00 and 450.0 all have four significant figures.

Mass of beaker = 24.2 g

Mass of beaker + mass of water = 30.625 g

Mass of water = 30.625 - Mass of beaker = 30.625 - 24.2 = 6.4g

The rule apply for the addition and subtraction is :

The answer would contain same number of decimal places as there are in the least precise number present.

Thus there are 2 significant figures in mass of water which is 6.4 grams.

For a point charge, how does the potential vary with distance from the point charge, r?

mr_godi [17]

For a point charge, how does the potential vary with distance from the point charge, r?

a constant

b. r.

c. 1/r.

d. $1/r^2$ .

e. $r^2$ .

Answer:

The correct option is C

Explanation:

Generally for a point charge the electric potential is mathematically represented as

$V = \frac{k Q }{r }$

Here we can deduce that the electric potential varies inversely with the distance i.e

$V \ \alpha \ \frac{1}{r}$
