Easy Quiz on on Physics For UPSC or SSC

Physics deals with a wide variety of systems, some of its theories were experimentally tested numerous times and found correct as an approximation of nature (within a certain domain of validity). Physics also makes significant contributions through advances in new technologies that arise from theoretical breakthroughs. Some of the day to day useful things of modern-day society, such as television, computers, domestic appliances, and nuclear weapons; advances in thermodynamics are due  to the development in the field of  physics

Here is third set of  10 questions on Physics

  1. It’s purely antecdotal but it feels like the amount of science literacy has gotten worse in recent years. What can we do to reverse that trend? Should we throw money at it? Give incentives to schools that do well in science? Make the standardized tests harder? More scholarships for science majors? Start a new PR campaign that makes science cool? Have the government appoint someone as a Science Ambassador? What do you think would work best?

  2. When a particle suffers a head-on elastic collision with another particle, initially at rest, the
    greatest fraction of kinetic energy is transferred if

    A. the incident particle is initially traveling very fast
    B. the incident particle is traveling very slowly
    C. the incident particle is much more massive than the target particle
    D. the incident particle is much less massive than the target particle
    E. the incident and target particle have the same mass

    the answer is E
    but why?
    thank you

    Religion pre-decides what nature is without much evidence or understanding of what nature is. Whereas science lets the experiments and the equations decide what nature is.

    She’s gonna come out as she is, and science is there to observe her as she is.

    But not religion. It pre-decides what she is. And it’s been demonstrated before that religion has been wrong; and it’ll be wrong again.

    And science is a continuous process. Science is always trying to understand her as she is. But not religion. Religion is stuck on seeing things in only religion’s way. And religion never likes to be corrected.

    Science and religion are incompatable.

  4. two people (one 80kg and the other 40kg) are standing on ice skates and they push off of each other. Who pushes off with the greatest force? Who experiences the greater acceleration?

  5. Bullets from two revolvers are fired with the same velocity. The bullet from gun #1 is twice as
    heavy as the bullet from gun #2. Gun #1 weighs three times as much as gun #2. The ratio
    of the momentum imparted to gun #1 to that imparted to gun #2 is:
    A. 2:3
    B. 3:2
    C. 2:1
    D. 3:1
    E. 6:1

    The Correct Answer is C. Pls. Explain

  6. What is more important to the self; science or a temprament and attitude of science in self.

    Is there any science which can help the self to enable and empower itself with knowledge and wisdom of self to enable and empower the self with an attitude and a temprament of science.

    What is this science; where can it be known and studied; how can it be practised. Can this science also help the self to enable and empower itself with knowledge and wisdom of any type and kind.
    Can we also use this science to help ourselves for enabling and empowering ourselves with that knowledge and wisdom which had been the cause, purpose, and reason of the existance, presence and working of self and the religion and god of self.

  7. A particular horizontal turntable can be modeled as a uniform disk with a mass of 200 g and a
    radius of 20 cm that rotates without friction about a vertical axis passing through its center. The
    initial angular speed of the turntable is 2.4 rad/s. A ball of clay, with a mass of 80 g, is dropped
    from a height of 35 cm above the turntable. It hits the turntable at a distance of 10 cm from the
    center, and sticks where it hits so that the clay and the turntable rotate together at a new angular
    speed. Assuming the turntable is firmly supported by its axle so it remains horizontal at all times,
    find the final angular speed of the turntable-clay system.

    I have limited science knowledge, currently studying economic in University. I would like to become a dermatologist to help others with their skin problems. Is it too late to start studying science, then apply for med school?

  9. give me prof that scientific laws can change!

  10. which of the following types of electromagnetic radiation can be used to check metal parts for damage? X-rays, Microwave or infrared radiation?

  11. Physics homework help!!!!! very important, need to get an A?
    an object is placed in front of a diverging lens with a focal length of 20.0 cm. For each object distance, find the image distance and the magnification. Describe each image.

    a. 40 cm
    B. 20.0 cm
    C. 10.0 cm

    i think one equatiom might jog ur memory, like 1 over p plus 1 over f equals 1 over q or something like tht, plz help me, i need to pass physics fo this quarter, i did the 1st 6 problems, but cant get these last two. thnx very very much

  12. Want to help me out?
    Would be greatly appreciated.

    Here’s all four:

    How does physics serve to improve our understanding of physical systems?

    How do the principles of physics effect your daily life?

    Describe something in nature that has become more compelling because of an understanding of physics principles

    Is it possible to describe the whole natural world (chemical and biological) with a small number of physical principles? If so, how?

    Is physics a redundant science? Do we now have a clear understanding of the interactions between matter and energy on all scales? Is technological application the main thrust of physics research today?

  13. a car stands beside a series of poles 4 m apart. it accelerates from rest at a rate of 2m/s^2 for 4 seconds, maintains its constant velocity for another 4 seconds, and brakes to rest in 2 seconds. how many poles have the car passed?

    can you please show me the solution? thanks

  14. I’m looking at a college and it says you have to have 3 years of lab science. What classes are those? I took earth science last year, and am planning on taking Chemistry, Chemistry II (not sure of the exact name) and physics. Are all of those lab sciences or what?

  15. Its what I want to study at university… I did A level Biology, Chemistry, Physics and Maths and really hated the maths. I got an A in Biology and Chemistry, an A* in Physics and I got a B in maths. D’you think I’ll cope with Physics in university?

  16. Tractors can ride through a mudy field that a car would readly sink into, even though the difference in wight is no that much. WHY ? What is the difference between the tractor and car?

  17. hello everybody. Lets say you had jet boots that were unstable. They provided upward thrust but you could not control the thrust. You might suddenly jet off to the right. So now, you have this idea. To a gauntlet, that works simialair to an Ion thruster. Now, you you turn you boots on. Your flying up. You suddenly jerk to the right. You power up your right hand trhruster. How much power would you need to stabilize. When I say power, how much power would you need to add to your gauntlet?

  18. I’m writing an essay on how literature and science affect the understanding of humanity and society. I’ve got the literature part down pretty well, but I am absolutely stuck on the science part. I have to choose either between natural sciences or human sciences and relate it to reason, but I don’t have any specific examples. Can you give me a few?

  19. gahhhh i hate science!

    anyway, we have to find manuplitive and responding variblies for my question. My question is how many of the barn owls prey are herbivores, omnivores, or carnivores. I neeeeeeeed help.
    btw, this is 6th grade Advanced Science.
    and please, no rude comments… i really need help.

  20. I want to study more on physics, but i dont know where to get good textbooks on my level. I am a middle schooler. I can comprehend higher than middle school level (probably), so i need some answers.
