Could the GPS system been invented from Newtonian physics

If so, would we have discovered the relativity theory due to it not functioning right?-We would have seen that something was not right, and perhaps, upon much further investigation, we would have disc

Is a free fall a true motion along a spacetime geodesic

Yes. For a sufficiently small point mass the geodesic is due to the background field. If the falling mass is large, its geodesic is due to all fields, including its own contribution to the overall net

Does Einstein's general relativity take in account that gravity itself carries energy

Since gravitational field carries energy, is it factored into his equations?-Of course.

Will wave length of sound will change with change in temparature

I mean if we changethe temperature of a sound wave passing area so that is there is any change in its wave length.how can we know that please tell me anyone-u = 20.046*√T m/swhere T is the Kelvin temp

Is it possible to time travel

someone told me that if we travel faster than the speed of light then we travel in the future? do u think this is true? is there any theory on travelling in the past?-Time Travel into the future is po

What term did Einstein prefer for his special "relativity" theory

Invariantentheorie.Another words theory of invariance.

Are inertial and gravitational energy the exact same thing

Or are there subtle/not too subtle differences?-Hum, Id say no. Theres a little query upon inertial and gravitational mass, but in terms of energy, I think the question has no sense. Gravitational ene

Physics Electric Potential Help

An electron is placed midway between two parallel conducting plates that are spaced 3.0 mm apart. The plates are attached to the terminals of a 12.0 V battery. a) What is the direction and magnitude

Physics- i really need step by step help please!

Problem # 1.) a cyclist and her bicycle have a combined mass of 75.0 kg. if the frictional force acting against the motion of the bicycle is -23.5 N, what force must the cyclist apply to maintain a co

How to do Centripetal Force

I have this question I have to answer about Centripetal Force...? I dont know how to do it. A child, who has a mass of 47900g, is sitting 6.20m from the center of a playground merry-go-round that is

Why doesn't a UV sensitive bead change colors when sunscreen is applied

I need to know and i cant find it on the web!!!!-Think about it like this, you wear sunscreen so you dont get burned. What makes you burn? UV rays. The UV rays are, of coarse, produced by the sun (hen

Questions about parallel forces

Why is torque error likely to be large? Can an error in one measurement be negated by error in another?-Torque error, or any error in a measurement can be due to losses (such as friction), inaccuraci

Current question (quick 10 points will vote asap)

A 12.0 V car battery with negligible internal resistance is connected to a series combination of a 3.5 ohms resistor that obeys Ohms law and a thermistor that does not obey Ohms law but instead has a

HELP!! 10 points!! A person is riding a bicycle, the wheels of a bicycle have an angular velocity of...

A person is riding a bicycle, the wheels of a bicycle have an angular velocity of +24.0 rad/s. Then, the brakes are applied. In coming to rest, each wheel makes an angular displacement of +16.0 revolu

How to find the center mass of ammonia molecule

Find the center of mass of the ammonia molecule. The chemical formula is NH3. The hydrogens are at the corners of an equilateral triangle (with sides 0.16 nm) that forms the base of a pyramid, with ni
