How do you determine the atomic mass of an element?

1 answer:

5 0

Answer:

For any given isotope, the sum of the numbers of protons and neutrons in the nucleus is called the mass number. This is because each proton and each neutron weigh one atomic mass unit. By adding together the number of protons and neutrons and multiplying by 1 amu, you can calculate the mass of the atom.

If the input force applied to one end of a first-class lever is 8 N, and the fulcrum is located 6 m away from the input force bu

MatroZZZ [7]

Answer:

16 N

Explanation:

The ratio of output force to the input force is called mechanical advantage of the lever. Also, the ratio of input arm distance to the output arm distance is called mechanical advantage of the lever.

We have,

Input force = 8 N

Input arm distance = 6 m

Output arm distance = 3 m

We need to find the resulting output force. So,

$\dfrac{F_o}{8}=\dfrac{6}{3}\\\\F_o=16\ N$

So, the resulting output force is 16 N.
