Radioactive elements are elements that involved in radioactivity and this comprises of atoms or particles in their nuclei whose atomic nuclei are not stable and they emit radiations to maintain stability.

Therefore, The kind of radioactive element is useful for dating an object is one with a half-life close to the age of the object.

You put scruffy can run up to 2 meters/sec on his fastest days scruffy has a mass of 8 KG what is his maximum kinetic energy on

ale4655 [162]

Answer:

E = 16 J

Explanation:

We have,

You put scruffy can run up to 2 m/s on his fastest days scruffy has a mass of 8 kg

It is required to find the maximum kinetic energy on his fastest days. If v is the velocity, then kinetic energy is given by :

$E=\dfrac{1}{2}mv^2$

Plugging all the values,

$E=\dfrac{1}{2}\times 8\times 2^2 \\\\E=16\ J$

So, the maximum kinetic energy on his fastest day is 16 J.

Calculate the molarity of a solution containing 9.25 mol H2SO4 in 2.75 L of solution.

Akimi4 [234]

Answer:

THE MOLARITY OF THE SOLUTION IS 3.36 MOLE/L

Explanation:

First we must understand what molarity is.

Molarity is the number of mole per unit volume of solution. In this question, 9.25 mole of H2SO4 was given in 2.75 L of solution.

Molarity is written in mole per dm3 or L.

So we can calculate the molarity:

9.25 ole of H2SO4 = 2.75 L of solution

The number of mole in 1 L of solution will be:

= 9.25 mole / 2.75 L

= 3.3636 mole/ L

In conclusion, the molarity of the solution is approximately 3.36 mole/L
