The other scale will either have a higher or lower number because 400 could be the bigger number or the smaller number but we don't know that so you cant exactly answer it.<span />
This question involves the concepts of the law of conservation of momentum and speed.
She moves with a speed of "0.41 m/s".
Applying the law of conservation of momentum to this situation, we get:
where,
m₁ = mass of shirley = 65 kg
m₂ = mass of tank = 12 kg
u₁ = initial speed of shirley = 0 m/s
u₂ = initial speed of tank = 0 m/s
v₁ = final speed of shirley = ?
v₂ = final speed of tank = 2.2 m/s
Therefore,
negative sign shows the opposite direction.

Answer:
sorry i cant understand ur questions okk g
C) gain one electron.
Explanation:
A chloride ion forms when a chlorine atom gains an electron. An atom is made up of three fundamental particles which are:
- Protons which are the positively charged particles in an atom.
- Electrons which are the negatively charged particles in an atom.
- Neutrons do not carry any charges.
In a neutral atom, the number of protons and electrons are the same.
For an atom to become charged, it must gain or lose electrons.
- When an atom gains electrons, the number of protons is less than the number of electrons and it is negatively charged. Such an atom is called an anion.
- When an atom loses electrons, the number of protons is more and it becomes positively charged. Such an atom is called a cation.
A chlorine atom that has gained an electron is an anion. It is negatively charged.

The microwaves have higher wavelength than visible light, but lower frequency than visible light and it also has lower energy than the visible light and that is the answer so I hope this will help you for whatever it is.
