4. If earth somehow expanded to a larger radius with no change in mass how would your weight be affected? How would it be affected if earth instead shrunk?Ans) As we know

g= Re The above equation show that value of g does not depend on mass of the body so heavy and light object fall with same acceleration.

7. The value of g changes it with location on earth however we take same value of g is 9.8ms2 for ordinary calculation. Why?Ans) The value of g changes slightly with height as the height as compared to theradius of the earth is negligible therefore the change is value of g is very small so wetake the value of g as 9.8 ms2 for our convenience.

How Is Physics Related To Technology

Every kind of technology makes use of principles articulated by the scientific discipline of physics. Even very simple technology, such as the wheel or the lever, have actions that can be described in terms of basic forces and matter interactions.

More complex technology, naturally, makes use of more rarefied physical concepts. GPS satellites, for example, adjust their internal timekeeping to account for the relativistic effects of their motion. Einsteins theory of Special Relativity describes the dilation of time that fast-moving objects experience. Without taking steps to correct for this change in the rate that time passes, GPS coordinates would be inaccurate by an unacceptable factor.

In general, physics describes the sort of things that are possible in the universe, and technology is eventually built to do work within the confines physics has discovered. This interplay works in reverse, as well. While early physicists may have been able to articulate basic principles with little more than thought experiments, modern physicists frequently make use of extremely high-tech machines and processes. The Large Hadron Collider in Switzerland, for example, is the worlds largest particle accelerator. It operates at higher energies than any previous collider, and it was built explicitly for the purpose of conducting experiments in particle physics.

Significance Of Physics In Modern Engineering

Physics lies at the core of designing, science, and technology. From the development of the light to the plan of a progressive new shuttle, Physics assumes an essential part in current advances.

To understand the significance of Physics in current designing. The student should refer to a couple of points of Physics:

  • Physics is a part of science that plans with different logical standards.
  • Physics has two disciplines, which are Classical Physics and Modern Physics.
  • Classical Physics, likewise calls Newtonian Physics, was create by Isaac Newton. A part of science manages the study of matter and energy regarding their interaction and kinetic effects. It is represents by Newtons laws of movement, attraction, and traditional mechanics.
  • Modern Physics is a part of science that deals with the investigation of matter, energy, and their interaction.
  • Coming up next are a few fields in Physics: Atomic Physics, General Physics, Classical Mechanics, Geophysics, and Nuclear Physics.

The students seeking after a college certification in designing should enroll in a class to study Physics. This is on the grounds that Engineering studies depend on the ideas of Physics.

They are used to foster effective systems that use the accessible resources and convert them into most extreme utility. In present day times, various sciences have been created. Furthermore, this has prompted the improvement of strong developments. Thusly, these developments have impacted the manner in which we live today. Certain individuals venture to say that technology defines our ongoing period.

A New Experiment Has Broken The Known Rules Of Physics Hinting At A Mysterious Unknown Force That Has Shaped Our Universe

An unknown force seems to be making subatomic particles called muons act weirdly. That same force could be behind dark matter.

Based on Teubner, it is possible that some pressure thats away from the Standard Type of physics could explain the muons whack-a-doo wobbles. That pressure, he stated, might also explain the presence of dark matter, and perhaps even dark energy which plays a key role in speeding up the development from the world. Theorists would think it is attractive to solve several problem at the same time, Teubner stated.

Importance Of Physics In Economic Development

In the United Nations Millennium Summit held in 2000, it was recognized that physics and the sciences will play a crucial role in attaining sustainable development. Physics helps in maintaining and developing stable economic growth since it offers new technological advances in the fields of engineering, computer science and even biomedical studies. These fields play a crucial role on the economic aspect of countries and finding new and better ways to produce and develop products in these fields can help boost a countrys economy. Similarly, the International Union of Pure and Applied Physics asserted that physics will generate the necessary knowledge that will lead in the development of engines to drive the worlds economies.

In Rwanda, the education ministry was mandated to develop the countrys scientific and technical know-how. Medical physics and information technology benefited the country by developing a national nutrition program and an epidemic surveillance system. Physics and engineering helped rural areas gain safe drinking water through gravimetric techniques, irrigation techniques and rainwater harvesting.

10)Can a single force applied to a body change both its translational and rotational motion? Explain.Ans) yes, it is possible if the force is applied on the center of the mass of the body thenthe body will perform translational motion and if it is applied on point other than centerof mass then the body will perform rotation.

11) Two forces produce produces the same torque. does it follow that they have the same magnitude? Explain.Ans) if two forces produce the same torques then it does not mean that they will have thesame magnitude because toque bot only depend on force but also depend on moment armfor example.

1. If there is an attractive force between all objects, why don’t we feel ourselves gravitating toward nearby massive buildings? Engr Miraj Ahmad 03329177174 / 03129177174

Ans) we dont feel ourselves gravitating towards the nearby massive buildings becausethe value of gravitation constant is very small which is equal to 6.67 x 1011 Nm2 kg2 andalso the mass of the building is small as compared to the earth.2. Does the sun exert a larger force on the earth than that exerted on the sun by the earth? ExplainAns) As the gravitation force between sun and earth depends on mass of both sun andearth and both exerts equal force on each other but both these force are equal inmagnitude but opposite in direction. Let the force exerted by sun on earth is F so and forceexerted by earth on sun is F os. Then F so=F os

9. Why does a boatman tie his boat to a pillar before allowing the passenger to step on the river bank? When a passenger from the boat move towards the river bank, pushes the boat inbackward direction with his feet. From Newtons third law of motion the reaction of the Engr Miraj Ahmad 03329177174 / 03129177174

boat is in opposite direction. However, when the boat is tie with pillar it cannot moveand hence the passenger move out from boat easily.

10. In uniform circular motion, if the velocity constant? Is the acceleration constant? Explain In circular motion the velocity direction changes continuously on eac point whichis tangent at that point, so we can say that the velocity does not remain constant incircular motion.

T = 0 N-mThis shows that gravitational force acting on satellite do not produce any torque.

6) Can we have a situation in which an object is not in equilibrium, even though the net force on it is zero? Give two examples.Ans) for complete equilibrium the two conditions of equilibrium must be satisfied, if netforce become zero and net torque become not zero then the body will rotate an dwill notbe in equilibrium, for example.

Proving quantum computers feasible

It has a lot to do with forces. Newtons laws of motion are involved. This is relevant to walking because when you put your foot on the ground, you are applying a force to it. In doing this, the ground also actually applies an equal force onto your foot, in the opposite direction, pushing you forward.
