Answer:

if any resistance in series the formula is R1+R2 =R

Explanation:

here R1 and R2 are resistance so let we assume we have two resistance of 8OHM and 15 OHM so,resultant resistance =8ohm+15ohm=23ohm the resultant resistance =23ohm.

ANSWER:

NEGATIVE ACCELERATION

Answer:

No magnetic field, with the possible exception of an electromagnetic PULSE from a nuclear blast, would disable a car.

Neither trains nor train tracks emit a significant magnetic field.

A magnetic field drops off extremely RAPIDLY, based on the square of the DISTANCE from the source.

So, given the fact that a train does not emit a significant magnetic field and that a magnetic field drops off rapidly from its source, we can assume the magnetic FORCES from the train do not exert influence on their environment. Further, we know the car is designed to be impervious to any typically occurring magnetic fields. Therefore, we can safely conclude that this THEORY was cooked up by somebody with an ignorance of both magnetism and automobiles and should lend it no credence to it whatsoever.

ANSWER:

EXPLANATION:SEE IMAGE

Answer:

Displacement (symbolized d or s ), also calledlength or distance, is a one-dimensional quantity representing the separation between two defined points. The STANDARD UNIT ofdisplacement in the INTERNATIONAL System of UNITS ( SI ) is the meter (m). Displacement is usually measured or defined along a straight line.

Answer:

16 ohm and 3 ohm

Explanation:

According to the GIVEN question,

R1 = 4 ohm and R2 = 12 ohm

And we are ASKED to find possible equivalent RESISTANCE.

We know, there are only TWO combination of resistors, i.e, series and parallel combination.

For series combination,

• R = R1+R2

Where R is equivalent resistance of series combination of R1 and R2.

Putting the values we get,

• R = 4+12 = 16 ohm

Again, for parallel combination

• 1/R' = 1/R1 + 1/R2

Where R' is equivalent resistance of parallel combination of R1 and R2.

Putting the values we get,

• 1/R' = 1/4 + 1/12

• R' = 4×12/16

• R' = 12/4

• R' = 3 ohm

Thus the two possible equivalent resistance are 3 ohm and 16 ohm.

_____________

Variable Frequency Control is a method which is used to control the speed of an induction motor. The synchronous speed and therefore, the speed of the motor can be controlled by varying the supply frequency.The synchronous speed of an induction motor is given by the RELATION shown below.

The EMF induced in the stator of the induction motor is given by the equation shown below.

equation 3

Therefore, if the supply frequency is changed induced EMF will also change to maintain the same air GAP flux. The terminal voltage V1 is equal to the induced EMF E1 if the stator voltage drop is neglected.

In order to MINIMISE the losses and to avoid the saturation, the motor is operated at rated air gap flux. This condition is obtained by varying the terminal voltage with frequency so as to maintain (V/f) ratio constant at the rate value. This type of control is known as Constant Volts Per Hertz.

Thus, the speed control of an induction motor using variable frequency supply REQUIRES a variable voltage power source. The variable frequency supply is obtained by the following converters.

Voltage source inverter

Current source inverter

Cyclo converter

An inverter converts a fixed voltage DC to a fixed or variable voltage AC with variable frequency. Cyclo converter converts a fixed voltage and fixed frequency AC to a variable voltage and variable AC frequency.

The variable frequency control allows good running and transient performance to be obtained from a cage induction motor. Cyclo converter controlled induction motor drive is SUITABLE only for large power drives and to get lower speeds

Answer:

Explanation:

Vibration is the back and forth or repetitive motion of an object from its POINT of rest.

When a force is applied to the mass, it stretches the spring and moves the weight to

the lower limit. When the force is removed, the stored energy in the spring causes the

weight to move upward through the position of rest to its upper limit. Here, the mass

stops and reverses direction traveling back through the position of rest to the lower

limit. In a friction-free system the mass would continue this motion indefinitely. All

real systems are damped, that is they will gradually come to their rest position after

several cycles of motion, unless acted upon by an external force. The characteristics

of this vibratory motion are period, frequency, displacement, velocity, acceleration,

amplitude and phase. Continued vibration of this spring mass system would only

repeat the characteristics shown in this single cycle.

All rotating machines produce vibrations that are a function of the machine dynamics,

such as the alignment and balance of the rotating parts. MEASURING the amplitude of

vibration at certain frequencies can provide valuable INFORMATION about the accuracy

of shaft alignment and balance, the condition of bearings or gears, and the effect on

the machine due to resonance from the housings, piping and other structures.

Vibration measurement is an effective, non-intrusive method to monitor machine

condition during start-ups, shutdowns and normal operation. Vibration analysis is

used primarily on rotating equipment such as steam and gas turbines, pumps, motors,

compressors, paper machines, rolling mills, machine tools and gearboxes. Vibration

analysis is used to determine the operating and mechanical condition of equipment. A

major advantage is that vibration analysis can identify developing problems before

they become too serious and cause unscheduled downtime. This can be achieved by

conducting regular monitoring of machine vibrations either on continuous basis or at

scheduled intervals. Regular vibration monitoring can detect deteriorating or defective

bearings, mechanical looseness and worn or broken gears. Vibration analysis can also

detect misalignment and unbalance before these CONDITIONS result in bearing or shaft

deterioration. Trending vibration levels can identify poor maintenance practices, such  

as improper bearing installation and replacement, INACCURATE shaft alignment or

imprecise rotor balancing.

ANSWER:

because of optical is RARER than water

Explanation:

since air is optically rarer than water the ray of LIGHT blend away from the normal at point INCIDENCE when moving towards the normal moving air to water

ANSWER:

The energy stored on a CAPACITOR can be EXPRESSED in terms of the work done by the battery. Voltage represents energy per unit charge, so the work to move a charge element dq from the negative plate to the POSITIVE plate is equal to V dq, where V is the voltage on the capacitor.

ANSWER:

Explanation:the RAY of LIGHT would GET refracted

ANSWER:

The answer is VELOCITY.

Answer:

No

Explanation:

Here, according to the DEFINITION distance is the total distance travelled by a body and DISPLACEMENT is the shortest distance travelled by a body or the distance travelled by a body from initial point to final point. Then, if displacement is ZERO then that means that the body has not travelled a shortest distance or else it has returned to its initial point again, but at least as it has travelled some PATH, then the distance I

here is a VALUE and not zero.
