Given that:
time (t) = 20 s ,
S = ?
We know that S = ut + 1/2 at² meters
since free fall, a = g = 9.81 m/s² ; u =0 ;
S = 0 + 1/2 × 9.81 × 20²
<em> S= 1962 m</em>
(a) The equivalent resistance of three parallel resistors is (R₁R₂R₃)/(R₁R₂ + R₁R₃ + R₂R₃).
(b) The total circuit current is 12/R.eq.
(c) The voltage drop across and current in each resistor is IR₁, IR₂ and IR₃.
<h3>
Equivalent resistance of three parallel resistors</h3>
The equivalent resistance of three parallel resistors is calculated as follows;
- Let the first resistor = R₁
- Let the second resistor = R₂
- Let the third resistor = R₃

<h3>Total Circuit Current </h3>
The total circuit current is calculated as follows;
V = IR

<h3>Voltage drop in each resistor</h3>
Voltage drop in resistor 1 = IR₁
Voltage drop in resistor 2 = IR₂
Voltage drop in resistor 3 = IR₃

Yes, it is <span>accurate to describe the physical universe as composed of only matter and energy. Some people might argue about the dark matter, but it is not yet defined properly. Different universes can be made up of different compositions but it is a fact that our universe is made of matter and energy. </span>
