What is the equivalent resistance for a series circuit with three resistors 19.2 ohms 24.6ohms, and 31.2 ohms?

Liula [17]

The equivalent resistance of two or more resistors in series is
the sum of their individual resistances.

If these three are all in series, then they act like a single resistor
whose resistance is

(19.2 + 24.6 + 31.2) = 75 ohms.

s344n2d4d5 [400]

Answer:

20 m/s

Explanation:

v = u + at

v: final velocity

u: initial velocity

a: acceleration

t: time

v = 10 + 2(5)

v = 10 + 10

v = 20 m/s

How is velocity ratio of wheel and axle calculated

Rudiy27

Answer:

VR = $\frac{Radius of the wheel}{Radius of the axle}$

Explanation:

Velocity ratio (VR) of a machine is a term that compares the distance moved by effort put into the machine to the distance moved by the load.

A wheel and axle is a device for lifting of a load through a height. It is made up of two circular parts called wheel and axle. Its velocity ratio (VR) can be determined by:

VR = $\frac{Radius of the wheel}{Radius of the axle}$

For a practical wheel and axle, the diameter of the wheel is greater than the diameter of the axle.
