The pressure exerted on the table due to the book is 200 N/m².
The given parameters;
- <em>mass of the book, m = 400 g = 0.4 kg</em>
- <em>dimension of the table, = 0.10m x 0.20 m.</em>
- <em>gravitational field strength g = 10 N/kg.</em>
The area of the table is calculated as follows;
A = 0.1 x 0.2 = 0.02 m²
The pressure exerted on the table due to the book is calculated as follows;
where;
- <em>F is the force of the book due to its weight</em>
<em />
Thus, the pressure exerted on the table due to the book is 200 N/m².

Answer:
q' = 0.5q
Hence, the charge stored is also halved
Explanation:
The capacitance of a capacitor is given by the following formula:
------- eqn(1)
where,
C = Capacitance of the capacitor
q = charge stored in the capacitor
V = potential across the capacitor
Now, if we make potential half of its initial value:
<u></u>
<u>q' = 0.5q </u>
<u>Hence, the charge stored is also halved </u>
Answer:
They are good terms to use for the inside and outside system because input refers to the inside parts and output refers to the outside parts .
Explanation:
Weak nuclear force:
The interaction between the subatomic particles is called weak nuclear force.
The weak nuclear force is one of the four fundamental forces.
The weak nuclear force is effective at very short distance.
The range and relative strength of weak nuclear force is 10⁻¹⁸ m and 10²⁵ with respect to gravitational force respectively
Deuterium is formed due to the fusion of protons and neutrons under the action the weak force.
Example : Beta decay
Electromagnetic force:
The interaction between the charged particles is called electromagnetic force.
The electromagnetic force is one of the four fundamental forces.
The electromagnetic force is effective at long range distance.
The range and relative strength of electromagnetic force is infinity and 10³⁶ with respect to gravitational force respectively
Example : light
