Incomplete question
This is the completed question
If the resistor in the circuit had a larger resistance then the current would be then have to be proportionally smaller. Because the batteries each give off 1.5 volts then the current would have to be the variable that would change. What affect would using a 12V car battery have on the operation of your circuit? (Do not try this.) What would happen to the current? What would happen to the resistor?
Explanation:
Using ohms law as our basis
Ohms law state that, the voltage in an ohmic conductor is directly proportional to the current
V∝I
Resistance is the constant of proportionality
Then
V=iR
Since we want a relationship between current and resistance.
then, I=V/R
So, current is inversely proportional to Resistance
as the current increase the resistance reduce and as the current reduces the resistance increases.
a. So, increasing the voltage from 1.5V to 12V increases the current In the circuit because voltage Is directly proportional to I.
From ohms law
V=iR
When v =1.5V
I=1.5/R
When V increase to 12V
I=12/R
I.e, it increases by a factor of 8. Eight times it's initial value
b. Now, the resistance in the circuit is the constant of proportionality and it doesn't change in a given circuit expect when using a variable resistoa r like rheostat.

Answer:
Current = 15 A
Resistance = 7.33 ohm
Magnetic field = 1.62 x 10^-4 Tesla
Explanation:
V = 110 V, P = 1650 W, r = 1.85 cm,
(a) Let i be the current
P = V x i
i = 1650 / 110 = 15 A
(b) Let R be the resistance
V = i R
R = 110 / 15 = 7.33 Ohm
(c) Let B be the magnetic field
B = μ0 / 4π x 2i / r
B = 10^-7 x 2 x 15 / 0.0185 = 1.62 x 10^-4 Tesla
Answer:
v₁ = 9 m/s
Explanation:
Here, we can use the continuity equation, as follows:
where,
A₁ = Cross-sectional area of the wider section = 48 cm²
A₂ = Cross-sectional area of the constriction = 12 cm²
v₁ = speed of flow in wider section = ?
v₂ = speed flow in constriction = 36 m/s
Therefore,
<u>v₁ = 9 m/s</u>
Answer:
The position of my house is a little uphill as compared to the position of my school. The distance I have to travel from my house to school is nearly 2 kilometers. The displacement is in the 2000 m towards the left from my house. The speed of the bus which I usually take is 40 km/ hour.
