To answer this question, you need to understand the naming of meter unit system. The unit pm stands for pico meter which was 1/1000 of nanometer. Then, the calculation would be:
Number of atom= container length / atom diameter
Number of atom = 25 nm x (1000pm/nm) / 144pm= 173.6 atom
There is no delay because the effects of gravity are constantly acting on bodies of water. Hence, option D is correct.
<h3>What is the gravitational effect?</h3>
Gravitation or just gravity is the force of attraction between any two bodies.
The Moon exerts over twice the gravitational pull of the Sun on Earth's tides because of its proximity to Earth. -The lunar tidal bulges are about twice the size of the solar tidal bulges. -The Sun's contribution to the tides is less than that of the Moon.
When the sun and moon are perfectly unaligned (they form a 90-degree angle relative to the earth), there are still tides because the moon's gravitational gradient is stronger than the sun's. The sun's gravitational gradient never completely cancels out the moon's.
Hence, option D is correct.

Answer:
Silicon dust has little adverse affect on lungs and does not appear to produce significant organic disease or toxic effects when exposures are kept beneath exposure limits. Silicon may cause chronic respiratory effects. Crystalline silica (silicon dioxide) is a potent respiratory hazard.
Answer:
H2O2
Explanation:
it is made up of Oxygen and Hydrogen. Unlike water which is H2O Hydrogen peroxide is made up of 2 oxygen atoms
