In a laboratory experiment, an ultrasound detector located at D is used to measure the distances of two moving objects, P and Q. At a certain moment, P and Q are located as shown in the diagram. What is distance PQ?. a) 6.82. b)5.66. c)4.74. d)4.24. e)3.89. .

Answers

Triangle PDQ has: 

     Side "p" is opposite Angle P 

     Side "d" is opposite Angle D = 45º + 23º = 68º 

     Side "q" is opposite Angle Q 


Use the Law of Cosines: 

         d²  =  p²  +  q²   −   2 • p • q • cos(D) 

         d²  =  (4.24)²  +  (4.24)²   −   2 • (4.24) • (4.24) • cos(68º) 

         d²  =  2(4.24)²   −   2(4.24)² • cos(68º) 

         d²  =  2(4.24)² • [ 1 – cos(68º) ] 

         d  =  4.74 ft

The distance PQ is 4.74 feet.

Calculations and Parameters:

Triangle PDQ has:

  •     Side "p" is opposite Angle P
  •     Side "d" is opposite Angle D = 45º + 23º = 68º
  •     Side "q" is opposite Angle Q

If we use the Law of Cosines:

d²  =  p²  +  q²   −   2 • p • q • cos(D)

d²  =  2(4.24)² • [ 1 – cos(68º) ]

d  =  4.74 ft

If you wanted to increase the voltage, which would you use?a. generator
b. step-up transformer
c. step-down transformer
d. motor
e. detector

Answers

The correct answer of the question is :  B) Step-up transformer.

EXPLANATION :

Before coming into any conclusion, first we have to understand the step-up and step-down transformer.

The step-up transformer is the transformer whose transformer ratio is greater than one. It means it will increase the voltage of the source or decrease its current.

On the other hand, the transformer ratio of step-down transformer is less than one. Hence, it will decrease the higher voltage to lower voltage or increase the lower current into higher current of the given source.

As per the question, we want to increase the voltage of the source.

Hence, we have to use step-up transformer.
b) step-up transformer
