Tech A says that a battery stores electrical energy in chemical form. Tech B says that a battery creates direct current. Who is correct?

Answers

Answer 1

Answer:

Answer:

Battery stores the electrical energy in the chemical form. When we connect it's positive and negative terminals and provide the path for the flow of electrons then it converts that chemical energy into the electrical energy and hence the direct current is created. So both of the technicians are right.

If a transformer has a primary with 100 V and fifty coils, and a secondary that yields 20 V, how many coils are on the secondary? a.) 200 b.) 20 c.) 50 d.) 10 e.) 100

Answers

Ideally, if all the magnetic of one winding cuts the other winding, and there isn't any loss in the transformer core or the resistance of the wire, then the voltage across each winding is proportional to the number of turns in its coil.

If you apply 100 V to a winding of 50 turns, then a winding that yields 20 volts
must be wound with

(20/100) of 50 turns = 10 turns

Which model of the atom has electrons traveling in specific paths around the nucleus? Bohr's model Rutherford's model Thomson's model Dalton's model

Answers

The model of the atom that has electrons traveling in specific paths around the nucleus is Rutherford's model.

Therefore, the correct answer is option B

J. J Thomson proposed that the atom is a sphere of positively charged matter in which negatively charged electron are embedded.

In Rutherford's model of atomic structure, the electrons moves in orbits by electrostatic attraction to the positively charged nucleus.

According to Dalton's atomic theory, atom were indestructible and indivisible solid particle.

Bohr's model made assumption that electron can only exist in circular orbits of definite quantum energy.

According to the question, the model of the atom that has electrons traveling in specific paths around the nucleus is Rutherford's model.

Therefore, the correct answer is option B

The Lamborghini Diablo sports car can accelerate from 0.0 km/hr to 99.2 km/hr in 4.0 seconds. What is the acceleration of this car? Give your answer in units of kilometers per hour/sec.

Answers

The Lamborghini Diablo sports car can accelerate from 0.0 km/hr to 99.2 km/hr in 4.0 seconds. What is the acceleration of this car? Give your answer in units of kilometers per hour/sec. To find the acceleration of the car we have to
1. First determine the suitable formula for this word problem. Which is a. A=vf-vi/t

Given are: Vf=99.2 km/h Vi= 0.0 km/h T= 4.0sec

Solution:
A= 99.2 km/h – 0.0km/h / 4.0 sec
A = 99.2 km/h / 4 sec
A = 2.8 km/h/sec

Answer:

24.8 km per second

Explanation:

a train travels 150 km in the same time that a plane travels 400 km. if the rate of the plane is 20 km per hour less than three times the rate of the train, find both rates

Answers

Answer:

Speed of train = 60 km/hr

Speed of plane = 160 km/hr

Explanation:

We can construct the following equations from the given information:

Speed of train * time = 150 -Equation 1

Speed of plane * time = 400 -Equation 2

Speed of plane = (3 * Speed of train) - 20 -Equation 3

We can solve these three simultaneous equations for the three variables (speed of train , speed of plane, time).

Substituting within Eq. 1 and Eq. 2 we get:

Speed of plane * 150 = 400 * Speed of train -Equation 4

Finally, solving Eq. 4 and Eq. 3 simultaneously we get:

Speed of train = 60 km/hr

Speed of plane = 160 km/hr
