Torch body if I’m wrong I’m really sorry that’s what I got
Answer:
# Initialize a dictionary with the keys
contestants = {"Darci Lynne":0, "Angelica Hale":0, "Angelina Green":0};
# Repeatedly prompt the user for a contestant name to vote for
while True:
# Prompting user for contestant name
cName = input("Enter contestant name to vote: ");
# Checking for Done
if cName.lower() == "done":
break;
# Checking in dictionary
if cName in contestants.keys():
# Updating vote value
contestants[cName] += 1
# New entry
else:
contestants[cName] = 1
# Printing header
print("\n%-20s %-15s\n" %("Contestant Name", "Votes Casted"))
# Printing results
for contestant in contestants:
print("%-23s %-15d" %(contestant, contestants[contestant]))
Answer:
V₂ = 20 V
Vt = 20 V
V₁ = 20 V
V₃ = 20 V
I₁ = 10 mA
I₃ = 3.33 mA
It = 18.33 mA
Rt = 1090.91 Ω
Pt = 0.367 W
P₁ = 0.2 W
P₂ = 0.1 W
P₃ = 0.067 W
Explanation:
Part of the picture is cut off. I assume there is a voltage source Vt there?
First, use Ohm's law to find V₂.
V = IR
V₂ = (0.005 A) (4000 Ω)
V₂ = 20 V
R₁ and R₃ are in parallel with R₂ and the voltage source Vt. That means V₁ = V₂ = V₃ = Vt.
V₁ = 20 V
V₃ = 20 V
Vt = 20 V
Now we can use Ohm's law again to find I₁ and I₃.
V = IR
I = V/R
I₁ = (20 V) / (2000 Ω)
I₁ = 0.01 A = 10 mA
I₃ = (20 V) / (6000 Ω)
I₃ = 0.00333 A = 3.33 mA
The current It passing through Vt is the sum of the currents in each branch.
It = I₁ + I₂ + I₃
It = 10 mA + 5 mA + 3.33 mA
It = 18.33 mA
The total resistance is the resistance of the parallel resistors:
1/Rt = 1/R₁ + 1/R₂ + 1/R₃
1/Rt = 1/2000 + 1/4000 + 1/6000
Rt = 1090.91 Ω
Finally, the power is simply each voltage times the corresponding current.
P = IV
Pt = (0.01833 A) (20 V)
Pt = 0.367 W
P₁ = (0.010 A) (20 V)
P₁ = 0.2 W
P₂ = (0.005 A) (20 V)
P₂ = 0.1 W
P₃ = (0.00333 A) (20 V)
P₃ = 0.067 W
The freaking answer iis the secシ❥❥☀︎︎
Answer:
Explanation:
The functions of the following are as follows:
1). Oil Rings:
- Regulates oil within cylinder walls.
- Helps to keep cylinder walls lubricated
- Prevent Heat transfer
- Reduce friction between piston and cylinder
2). Fly Wheel:
- It is used to store rotational energy
- It resist any change in rotational speed due to its moment of inertia
- It helps to control the orientation of the mechanical system
3). Timing gears:
- It provides synchronization in the rotation of crankshaft and the camshaft so as to provide proper valve opening and closing time during each cylinder's stroke(intake and exhaust).
