Answer:
1. Current in the circuit; 1.2 Amps
See attached image for the circuit.
2. Equivalent resistor = 3 Ω
I = 0.3 amps
Potential difference across the battery terminals is: 0.9 V
Explanation:
Part 1.
The internal resistance of 2 ohms is simply added to the circuit in series as shown in the attached image.
Since now we have two resistances in series (2 ohms and 3 ohms) the total of this series combination is 5 ohms. Using Ohm's law, we can derive the current running through the circuit:
Part 2.
Now we have a 1.5 V battery with a 2 ohm internal resistance, connected to two identical 6 ohm resistors.
a. The equivalent resistance presented by the two resistors in parallel:
b. Now the circuit can be represented by a 2 ohm resistor (internal battery resistance) plus a 3 ohm parallel equivalent resistor in series. That is a 5 ohm total resistance. Then Ohm's law becomes:
c. The potential difference across the battery terminals must be the battery's EMF minus the potential drop in its internal resistance:
Answer:
T=1.384×10⁶seconds
Explanation:
Given data
p (Intensity)=1.30 kw/m²
E (Energy)=1.8×10⁹ J
A (Area)=1.00 m²
T (Time required)=?
Solution
E=PT ................eq(i)
where E is energy
P is radiation power
T is time
Radiating Power is given as
P=pA
Where p is intensity
A is Area
Put P=pA in eq(i) we get
E=pAT
T=E/pA
Answer: 7.723s
Explanation:
given data:
initial velocity = 7.56 m/s.
friction = 0.0695.
change in velocity = 2.32 m/s
<u><em>Solution:</em></u>
Answer:
To find the mass using density and volume we just multiply them against each other which causes ml to cancel and just leaves us with grams which represents how much the item weights.
Therefore, our final answer is that our pencil weight 3.5 grams
