An adult should have no more than 2568 mg of sodium per day. what is this limit in kilograms (kg)?

2.568 × 10⁻³ kg

Explanation:

The amount of sodium to be taken by an adult is measured in terms of a limit, as given here.

That limit has been set as 2568 mg , when measured in milligrams.

The basic conversion from milligrams to g is done by dividing with 1000. Then 2568 milligrams will be 2.568 grams.

Now 100 grams are present in 1 kilogram.

So 2.568 grams are divided with 1000 to get the specified mass in kg.

The gives it as 2.568 × 10⁻³.

at positions a, g kinetic energy is maximum.

at position d, potential energy is maximum.

the body's situation won't change the forces are equal opposit and on the same body
