Test Your Knowledge on Physics Easy Quiz 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 second 10 questions on Physics

  1. 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.
    PLEASE EXPLAIN HOW TO DO IT!!

  2. give me three kinds of bacteria that causes diseases

    and name me one kind of protist that causes disease and leave links that would be helpfull if you want 10pts

  3. 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?

  4. 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.

  5. I’m going to do a project based on what type of glue will work the best on different materials. Can anyone help me figure out what category that would fit in, you know, like Behavioral sciences, physical science, botony, ecology, those types of categories. Please, some help!

  6. 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.

  7. 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?

  8. 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?

  11. give me prof that scientific laws can change!

  12. wHAT HAPPENS TO THE ELEMENTS IN IRON ORE WHEN THE ORE IS MIXED WITH CARBON AND HEATED

  13. 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

  14. 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?

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

  16. Hi,

    Mathematics and computer science are not natural sciences, applied sciences (technology) or social sciences.
    So, what kind of sciences are they?

    I found out that they may belong to constructive sciences or formal science but I am not sure.

    PLEASE DO NOT ANSWER WITH LINKS.

    Thanks.

  17. 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?

  18. 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?

    At my school I have many different math and science classes i can take after im done with the ones i need to take. I want to take a math and a science class that will help me better for when im in collage, then veterinarian school. For math, there is, pre-calculus, statistics, trigonometry/analytic geometry(one course), and business math. For science, there is, chemistry, physics, marine science, and anatomy/physiology(one course). Please help thank you!

  20. Constructive interference will maximize the amplitude of two waves of identical wavelength if they are offset by:
    wavelength/4
    wavelength/2
    wavelenth/pi
    wavelength/2pi
    wavelength

  21. 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.

  22. 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?

    I need to know some ways to change the viscosity of a liquid. I already have temperature, which is an obvious one. There are no sites that help me and I need more then one way. Please help!
    (grade 8 science)

  24. where can I find useful websites about physics? especially physics that deal with engineering

    Thank you!!

  25. 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

  26. I have three choices: physics, environmental science, and aquatic science. Im a junior at this moment. I heard that physics is alot of math and Im descent at math but im already going to take Precal and that already seems to much for me. The other two classes are supposed to be easy. Wat do you guys suggest? Thanks for answers.

  27. I’m planning to switch from Engineering to Archaeology, and the last thing I need is more physics. :/ So if there’s as much physics in Archaeology as Engineering requires (esp. the same kinds of physics classes), then I’m dropping my plan to major in Archaeology though it is such an interesting subject because I do understand physics, I’m afraid.

  28. Usually science would begin with observations and a hypothesis. But i’m beginning to think that a conclusion from a previous experiment would be a cause to start up a new experiment.
    Would true science be?

  29. Science describes the universe, ideology comments on it.

    Then again, ideologues have created their own universe.

  30. Lots of science shows, catchy music to go along with learning about the planets, witty science writers, etc. Does this all really help in knowing the type of work/preparation that is required for science disciplines? I’m thinking of people planning to begin a course of study in science. I suppose a measure of popularity is okay for the general public.
