Travka [436]

Answer:

<h3>The answer is 900 J</h3>

Explanation:

The potential energy of a body can be found by using the formula

PE = mgh

where

m is the mass

h is the height

g is the acceleration due to gravity which is 10 m/s²

From the question we have

PE = 45 × 10 × 2

We have the final answer as

<h3>900 J</h3>

Hope this helps you

The mass of each WtWt isotope is measured relative to C−12C−12 and tabulated below. Use the mass of C−12C−12 to convert each of
Nadya [2.5K]

The question is incomplete , the complete question is;

The mass of each Wt isotope is measured relative to C-12 and tabulated below. Use the mass of C-12 to convert each of the masses to amu and calculate the atomic mass of Wt.

Wt-296  =  24.6622

Answer:

The atomic mass of Wt-296 is 195.9464 amu.

Explanation:

1 amu is defined as 1 by twelfth of the carbon-12 mass.

Mass of an isotope Wt-296 = 24.6622

Mass of an isotope Wt-296 in amu = M

M\times \frac{1}{12 amu}=24.6622

M=24.6622\times 12 amu=295.9464 amu

The atomic mass of Wt-296 is 195.9464 amu.
