The correct answer is B. a fossilized fish

That is because the scientist can use carbon dating to find the age of the fish, and that will tell the scientest the date of the layer of rock. :)

1. A solution has a volume of 2500 mL. How<br>many liters is this?<br>​
pentagon [3]

The volume of the given solution is 2.5 L.

<u>Explanation:</u>

Volume of the solution = 2500 mL

We have to convert it into litres as,

1000 mL = 1 litre

To convert ml into litres we have to divide the millilitres by 1000, so that it can be converted into L.

Here given volume is 2500 mL.

Volume in L = $\frac{2500}{1000}  

                   = 2.5 L

So the volume of the solution is 2.5 L.

Which has the most gravitational potential energy- a 10 kg ball that is 2 meters high or a 10 kg ball that is 4 meters high?
Alenkasestr [34]

Answer:

The 10 kg ball that is 4 meters high is greater than a 10 kg ball that is 2 meters high

Explanation:

From the question,

Gravitational Potential Energy of the first ball

P.E1 = mgh.................... Equation 1

Where P.E1 = Gravitational Potential Energy of the first ball, m = mass of the first ball, h = height of the first ball, g = acceleration due to gravity.

Given: m = 10 kg, h = 2 m

Constant: g = 9.8 m/s²

Substitute these values into equation 1

P.E1 = 10×2×9.8

P.E1 = 196 J.

Similarly,

Gravitational potential energy of the second ball is

P.E2 = m'gh'................... Equation 2

Where P.E2 = Gravitational potential Energy of the second ball, m' = mass of the second ball, h' = height of the second ball.

Given; m' = 10 kg, h' = 4 m

Substitute these values into equation 2

P.E2 = 10×4×9.8

P.E2 = 392 J

From the above calculation,

P.E2 is greater than P.E1.

Hence, the 10 kg ball that is 4 meters high is greater than a 10 kg ball that is 2 meters high

What property of a solution causes an acid–base indicator to change to different colors?
Sati [7]
The most common method to get an idea about the pH of solution is to use an acid base indicator. An indicator is a large organic molecule that works somewhat like a " color dye". Whereas most dyes do not change color with the amount of acid or base present, there are many molecules, known as acid - base indicators<span> , which do respond to a change in the hydrogen ion concentration. Most of the indicators are themselves weak acids.</span>
