Answer:
i think its B sorry if its wrong
In order to answer this, you can use this formula :
F = m.a
which means
a = F/m
a = 18N / 2kg
a = 9 N/kg or 9m/s2
hope this helps
Answer: The rate of energy transfer by a 5 ohms resistor when there is a current of 0.2 A in it.= 1.25 watt.
Explanation:
- The rate of energy transfer from one point to another is known as power.
- Its SI. unit is <em>Watt.</em>
Formula to compute power:
Power = , I = cureent, R = resistance.
Given R = 5 ohm , Current = 0.5 A.
Then, power =
Hence, the rate of energy transfer by a 5 ohms resistor when there is a current of 0.2 A in it.= 1.25 watt.

Atomic number of phosphorus is 15
15 electrons.
Explanation:
An atom is made up of subatomic particles. These particles are:
- Protons which are positively charged.
- Electrons are negatively charged
- Neutrons carry no charges.
Atomic number is the number of protons in an atom.
For atoms that has no charge, the number of protons and electrons are the same.
On the periodic table, atoms are arranged based on their atomic number. If phosphorus is the fourth element to the right of sodium, then the atomic number of Phosphorus will be (11+4) = 15.
The atom has no charge and so the number of electrons will be 15 same as the atomic number.
