The apple is lifted by 1.1 m
<u>Explanation</u>:
- Given that, mgh = 2 J and mass of apple = 180g
- Step 1: convert grams to kg as work is given in SI units.
180 g = 0.18 kg
- Step 2: substitute in the formula for work done.
0.18 * 10 * h = 2
- Step 3: calculate the value of h from this formula.
h = 2/1.8
h = 1.11 m
Answer:it is due to present of water amount in our body. Our body consists 70%of water and 1/3of oxygen and 2/3 of hydrogen.
Explanation: human body consist of 1/3 of oxygen and 2/3 of hydrogen because oxygen contain 16 times more mass than hydrogen atom, hydrogen has only 1 proton so its atomic no. is 1 whereas oxygen has 8 proton and 8 neutrons so its atomic no.is 8 and mass is 16 so overall it takes 16 hydrogen atoms to equal to the mass of 1 oxygen atom.
