<h3><u>Given </u><u>:</u><u>-</u><u> </u></h3>
- A certain circuit is composed of two series resistors
- The total resistance is 10 ohms
- One of the resistor is 4 ohms
<h3>
<u>To </u><u>Find </u><u>:</u><u>-</u></h3>
- We have to find the value of other resistor?
<h3><u>Let's </u><u>Begin </u><u>:</u><u>-</u></h3>
We know that,
In series combination,
- When a number of resistances are connected in series, the equivalent I.e resultant resistance is equal to the sum of the individual resistances and is greater than any individual resistance
<u>That </u><u>is</u><u>, </u>
Rn in series = R1 + R2 + R3.....So on
<u>Therefore</u><u>, </u>
<u>According </u><u>to </u><u>the </u><u>question</u><u>, </u>
We have,
R1 + R2 = 10 Ω
4 + R2 = 10Ω
R2 = 10 - 4
R2 = 6Ω
Hence, The value of R2 resistor in series is 6Ω
The charge on the droplet must be
Explanation:
In order for the oil droplet to be in equilibrium, the force of gravity acting on it (the weight, acting downward) must be equal to the electrical force acting upward.
The gravitational force is:
which is equivalent to the weight of the droplet.
The electric force is given by:
where
q is the charge on the oil droplet
is the magnitude of the electric field
Since the two forces must be equal,
And solving for q,

Answer:
s = 147.54 m
Explanation:
given,
initial velocity,u = 45 mi/h
1 mph = 0.44704 m/s
45 mph = 45 x 0.44704 = 20.12 m/s
final velocity, v = 65 mi/h
v = 65 x 0.44704 = 29.06 m/s
time, t = 6 s
acceleration,
a = 1.49 m/s²
distance travel by the car
using equation of motion
v² = u² + 2 a s
29.06² = 20.12² + 2 x 1.49 x s
2.98 s = 439.6692
s = 147.54 m
distance traveled by the car is equal to 147.54 m
I do not understand what your saying could u plz be more specific?
