Test Your General Knowledge on Physcis for USPC or SSC -1

General knowledge about Physics  is very important for UPSC and SSC exams. Physics a natural science that involves the study of matter and its motion through space time, along with related concepts such as energy and force.More broadly, it is the general analysis of nature, conducted in order to understand how the universe behaves.Physics is one of the oldest academic disciplines, perhaps the oldest through its inclusion of astronomy. Over the last two millennia, physics was a part of natural philosophy along with chemistry, certain branches of mathematics, and biology, but during the Scientific .

    the answer is E
    but why?
    thank you

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

  6. 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

  7. 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.

  8. 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. 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.

  10. 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.

  11. 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?

  12. 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

  13. give me prof that scientific laws can change!

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

    Thank you!!

  15. 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?

  16. 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?

  17. Physics homework help!!!!! very important, need to get an A?

    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

  18. 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!!

  24. 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.

  25. I am a very devoted Muslim. I really like physics. I found out that many physicists are atheists. So , what kind of fields in physics can I work in and still be a devoted Muslim who believes in God.
    Can you leave me a small list of fields I can work in and still be a believer(fluid dynamics, quantum theory….).
    If I can’t be a devoted Muslim believer then I will forget physics.

  26. 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.

  27. How did Science play a role during the Renaissance and why was science another means to disobey the church? Why was it taking a risk to be a scientist during the Renaissance?

  28. I have been conditionally accepted into a respiratory therapist program but have never taken any Physics perviously and one of the requirments is 112 physics. I am planning to take a correspondence course via a local college, but am worried about not being able to understand the concepts of physics. I would greatly appreciate some insite on what Im up against! Thanks!

    PS: Also if you know how interelated the concepts of physics and respiratory therapy are it would be nice to know.

  29. I am working on a physics project in which I have to discuss different topics (in physics) that deal with power boats. I can go into detail on the friction of water, velocity, etc., but I was looking for more in-depth details and more interesting concepts. Physics is not my strongest subject, so any intellectual information would be helpful.

    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.
