<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

Answer:
Hey
The thickness of a planet's atmosphere determines the tempature. the reason why is because gas traps or reflects light. Gass molecules generally reflect light which means that photons bounce of gass molecules. But the space between these molecules allows most of the light to travel through and hit the planet.

Answer:
From the graph, at t = 5 seconds, the velocity = 50 m/s as shown also in the above table
Please find attached the graph
Explanation:
The initial velocity of the body = m/s
The acceleration of the body = 8 m/s²
The velocity after 5 seconds can be determined graphically and by calculation as follows;
Graphically, we have the data points which can be found by the straight line relation v = u + a×t,
Where ,
a = The slope = 8 m/s²
u = 10 m/s = The y-intercept
Which gives;
v = 10 + 8 × t
The following data can be calculated for various time t;
Time, t Velocity
, v
0, 10
1, 18
2, 26
3, 34
4, 42
5, 50
6, 58
From the graph, at t = 5 seconds, the velocity = 50 m/s as shown also in the above table
Please find attached the graph
By calculation, we have;
v = u + a×t
Where;
v = The final velocity
u = The initial velocity = 10 m/s
a = The acceleration = 8 m/s²
t = The time = 5 seconds
v = 10 + 5× 8 = 50 m/s.
