An automobile engine exerts aforce of 595 N to propel the car at 90.0 km/h on a level road.  What is the power output of the engine at
that time?

Answers

Answer 1
Answer: It's exactly enough to replace the energy lost to friction and air resistance. We have no information with which to evaluate those. Without friction and other losses, it takes no force and no power to keep a car moving at any speed in a straight line.
Answer 2
Answer: the power would be 595*90=53550w

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

Answers

Light ... and all other forms of electromagnetic radiation ... behaves
as if it were a stream of 'packets' that we call 'photons', each one
carrying a specific amount of energy.

Light  ... and all other forms of electromagnetic radiation ... is
characterized by its wavelength.  That is, once you state its wavelength,
you've stated everything there is to know about the light, including its
frequency, and the energy carried by each photon. 

Simon draws a diagram to illustrate the law of reflection.Which best explains how Simon can correct the error in his diagram?

Draw the incident ray so it is longer than the reflected ray.
Make the angle of reflection and the angle of incidence equal.
Switch the labels for incident ray and reflected ray.
Make the angle of incidence larger than the angle of reflection.

Answers

Answer:

Make the angle of reflection and the angle of incidence equal.

Explanation:

The law of reflection states that at the point of incidence on a smooth surface, the angle of incidence is equal to the angle  of reflection, The incident ray, the normal and the reflected ray lie on the same plane.

Answer:

B.  Make the angle of reflection and the angle of incidence equal

I hope my answer has come to your help. God bless and have a nice day ahead!

Answer:

Universe contains galaxies, stars and planets.

Explanation:

The Universe is the assumed to be made of three different kind of matters which is

1- Dark matter ( 25 %)

2-Normal matter (5%)

3- Dark energy (70%)

The Universe has billions of galaxies in it, each one of galaxy has planets and  millions of stars. It is the collection of everything that exist in the space including clouds of gas and vast empty spaces between planets and stars.
