Light's speed only depends on the substance (medium) it's moving through.
It travels at a constant speed as long as it stays in the same medium.
Light has the fastest speed when it's in vacuum, and nothing moves faster than that speed.
Streamlining helps to cut through and reduces the force acting on any object. It helps the object to move swiftly.
Answer:
2 and 0.6 ohms = 1.8A
4ohms = 1.08A
6 ohms = 0.72 ohms
Explanation:
With the help of the given diagram calculate the current through each resistor.
According to ohms law
E = IRt
E is the electromotive force = 9V
I is the total current in the circuit
Rt is the total equivalent resistance
Get Rt
1/R = (1/4+1/6) (parallel resistors)
1/R = 3+2/12
1/R = 5/12
R = 12/5
R = 2.4 ohms
Rt = 2 + 0.6 + 2.4
Rt = 5 ohms
Get the total current
I = E/Rt
I = 9/5
I = 1.8A
Since same current flows in a series connected resistors
Current in the 2 and 0.6 ohms resistors will be 1.8A
For the 4 and 6 ohms resistor:
Voltage across them is expressed as:
V = IR
V = 1.8(2.4)
V = 4.32Volts
The current in 4 ohms resistor
I = 4.32/4
I = 1.08A
The current in 6 ohms resistor
I = 4.32/6
I = 0.72A
Answer:
1.24 m/s
Explanation:
Metric unit conversion:
9.25 mm = 0.00925 m
5 mm = 0.005 m
The volume rate that flow through the single pipe is
This volume rate should be constant and divided into the 4 narrower pipes, each of them would have a volume rate of
So the flow speed of each of the narrower pipe is:
