It would be six because in every one molecule, there are three atoms of hydrogen, so just double that and you have six.
Answer:
Explanation:
Work is the product of force and distance.
We know the force to lift the rock was 50 Newtons. The work was 150 Joules.
- 1 Joule is equal to 1 Newton meters.
- We can convert the units to make the problem simpler later. The work is also 150 Newton meters.
Substitute the values into the formula.
We want to solve for distance, so we must isolate the variable. Divide both sides of the equation by 50 Newtons.
The Newtons will cancel out.
The rock was lifted <u>3 meters.</u>
Answer:
We can remove ions and water molecules
Explanation:
We can remove ions and water molecules because both of them have an electric field . So this will help in repelling or attractive the above mentioned particles. Water is polar so it has an electric field due to net dipole moment.
They are called magnets poles.
Answer: The pressure in a liquid is different at different depths. Pressure increases as the depth increases. The pressure in a liquid is due to the weight of the column of water above. The greater pressure at the bottom would give a greater 'force per unit area' on the wall.
