A ray passing through optical centre don't deviate ? why​

Physics
1 answer:
artcher [175]3 years ago
4 0

Answer:The middle part of the lens will just act as a rectangular glass slab. ... In thin lenses the perpendicular distance between extended incident ray and extended emergent ray is negligible. So this is why we can say that light ray passes through optical centre without deviation. I hope this helps you :)

Which of the following statements is true? Sound waves create areas of high and low pressure. Areas of high pressure are called
blsea [12.9K]

Answer:

All of the above

Explanation:

Sound waves are mechanical waves consisting of the oscillations of the particles in a medium. They are longitudinal waves, which means that the vibrations of the particles occur in a direction parallel to the direction of propagation of the wave.

This type of wave consists of alternating regions where:

- the density of the particles is higher: these regions are called compressions, and they correspond to high pressure regions

- the density of the particles is lower: these regions are called rarefactions, and they correspond to low pressure regions

A man tries to push a 200 kg Car that moves at a acceleration 0.50 m/s2. The man is able to displace the car 10 m. How much work
yawa3891 [41]

The work done by the man pushing the car over the given distance is 1000J.

Given the data in the question;

  • Mass of car; m = 200kg
  • Acceleration of the car; a = 0.5m/s^2
  • Distance covered by the car; d = 10m

Work done; W = \ ?

<h3>Work done</h3>

Work done is simply defined as the energy transfer that takes place when an object is either pushed or pulled over a certain distance by an external force. It is expressed as;

Work\ done = f * d

Where f is force applied and d is distance travelled.

To determine the work done by the man, we first solve for the force applied F.

From Newton's Second Law; Force \ F = m * a

We substitute our given values into the expression

F = m * a \\\\F = 200kg * 0.5m/s^2\\\\F = 100kg.m/s^2

Next we substitute our values into the expression of work done above.

Work \ done = f * d\\\\Work \ done = 100kg.m/s^2 * 10m\\\\Work \ done = 1000kgm^2/s^2\\\\Work \ done = 1000J

Therefore, the work done by the man pushing the car over the given distance is 1000J.
