A weight lifter raises a 1600 N barbell to a height of 2.0 meters. How much work was done? W = Fd
2 answers:
Answer : Work done, W = 3200 Joules.
Explanation :
The force acting on the berbell,
The height attained by it,
We know that the relation between the work done, force acting and the displacement is given by :
The work done will be 3200 Joules.
So, the correct option is (D).
Hence, this is the required solution.

The actual weight of the gas = apparent weight + weight.
The actual weight = + W
Given that a plastic bag is massed. It is then filled with a gas which is insoluble in water and massed again.
If the apparent weight of the gas is the difference between these two masses, then let the apparent weight =
The gas is squeezed out of the bag to determine its volume by the displacement of water. Since
density = mass / volume
The density of water is 1000 kg/
we can get the mass of the gas by making m the subject of the formula.
W = mg
The actual weight of the gas = apparent weight + weight
That is,
The actual weight = + W

Answer:
The Arsenic has three electron-containing orbitals. The orbitals s, p and d.
Explanation:
Arsenic is an element with an atomic number equal of 33, it means that it has 33 electrons in its orbitals in the following way:
Therefore, the Arsenic has three electron-containing orbitals (s, p d).
