Wavelength = speed / frequency 
 = 7 km/s / 12 /s
 = 0.58 Km

In short, Your Answer would be 0.58 Km or 580 m

Hope this helps!

A patient comes to an outpatient laboratory for a physician-ordered fasting test. The patient indicates that he forgot that the
Fynjy0 [20]

The patient eating a candy bar instead of fasting for the test should be told

that the test results will be wrong and he may receive a wrong diagnosis.

The medical practitioners told him to fast when coming for a reason and he

forgetting and eating something means the objective for the test may have

been defeated.

This is why it's best to explain to him about the consequences of his actions

which is likely getting a wrong result and diagnosis.

What is the difference between an induced and a permanent magnet?
MissTica
INDUCTION MOTOR:-

Speed:-Less speed range than PMAC motors • Speed range is a function of the drive being used — to 1,000:1 with an encoder, 120:1 under field-oriented control


Reliability:-Waste heat is capable of degrading insulation essential to motor operation • Years of service common with proper operation

Power density:-Induction produced by squirrel cage rotor inherently limits power density

Accuracy:-Flux vector and field-oriented control allows for some of accuracy of servos

Cost:-Relatively modest initial cost; higher operating costs

PERMANENT MAGNET MORTOR:-

speed:-VFD-driven PMAC motors can be used in nearly all induction-motor and some servo applications • Typical servomotor application speed — to 10,000 rpm — is out of PMAC motor range

Reliability:-Lower operating temperatures reduces wear and tear, maintenance • Extends bearing and insulation life • Robust construction for years of trouble-free operation in harsh environments.

power density:-Rare-earth permanent magnets produce more flux (and resultant torque) for their physical size than induction types.

Accuracy:-Without feedback, can be difficult to locate and position to the pinpoint accuracy of servomotors

<span>Cost:-Exhibit higher efficiency, so their energy use is smaller and full return on their initial purchase cost is realized more quickly</span>

alekssr [168]

Complete Question

A step-up transformer is connected to a generator that is delivering 197 v and 113 A. The ratio of the turns on the secondary to the turns on the primary is 600 to 5. What is the voltage across the secondary

Answer:

The voltage is V_s  =  23640  \  V

Explanation:

From the question we are told that

   The  voltage is  V_p  = 197  \ V

    The current is  I  =  113  \  A

   The  number of turn on the secondary is  N_s =  600 \ turns

    The  number of turn on the primary is  N_p =  5 \  turns

Generally from the Transformer Turns ratio equation

    \frac{N_s}{N_p} = \frac{V_s}{V_p}

=>  \frac{ 600}{ 5} = \frac{V_s}{197 }

=>  V_s  =  23640  \  V
