In this world, universe anything is possible. The whole life concept - we are here, it happened from NOWHERE, from somewhere we dont even know. So time machine is possible too but we jsut dont know. You can travel back or forward in time using your mind. All we need to do is to add physics...

Can you determine the volume of an ideal gas (PV = mRT) if you only know T,P, and m? Or do I need to find R for the particular substance?

Wouldnt it take 14 billion years for the light to travel from the telescope to the appointed star?

Assume you and I are the same age....

If I traveled the speed of light for 20 years with respect to you, 20 years would not have passed with respect to me

If I was at the event horizon of a super massive black hole for 20 years with respect to you, 20 years would not have passed with respect to me.

I am building my own type of heating system: A meander of copper pipes under the floorboards of my house is filled with water. The water is in a closed cycle and gets warmed up by an instant water heater, which gets its power from a wind turbine capable of delivering 400W. While this may not sound like much, consider that the water heater will be fed with pre-warmed water all the time, as "what goes around comes around" I am hoping to create some serious heat with this (well, at least enough to keep an old Victorian house cozy at temperatures around freezing point). Would you say that could work? I am very unsure of myself, because I know nothing about plumbing and heating.
I'd be very grateful for input.
Thanks.

A car traveling at 29 m/s (65 mi/h) runs into a bridge abutment after the driver falls asleep at the wheel.

If the driver is wearing a seat belt and comes to reat within a 1.0 m distance. what is his acceleration?

A passenger who isn't wearing a seat belt is thrown into the windshield and comes to a stop in a distance of 10.0 cm what is the acceleration of the passenger?

Okay, so we have to find two accelerations, what formulas do i use to find out what they are...

1) We want to graph the function y = x^6 so it looks linear. Should we use a semi-log or log-log graph?
What is the slope and intercept of the straight line? State your reasoning.

2) We want to graph the function y = 5.e^(3.x) so it looks linear. Should we use a semi-log or log-log graph?
What is the slope and intercept of the straight line? State your reasoning.

3) In a clear sentence, what is the usefulness of a log-log graph?

4) In a clear sentence, what is the usefulness of a semi-log graph?

Good Luck! :)

I am supposed to draw a FBD for a car traveling around a "loop-the-loop". It is at its highest point in the loop. Am I correct in saying the acceleration is straight down, towards the center? Also, was force(s) should I have on this FBD other that gravity? We are to assume negligible friction. I also need an equation for the force in the radial direction (vertical in this case). Car has mass m and loop has radius r. Should the equation be that F=m*v^2/r^2 or something similiar to that? Answer one part if that's all you can help with. Thanks!

A shell is fired forom the ground with an initial speed of 1700 m/s at an initial angle of 58 degrees to the horizontal
The acceleration of gravity is 9.81 m/s2
Neglecting air rexestance how do I find the shell's horizontal range and the amount of time the shell was in motion?

A baseball is thrown at an angle of 26 degrees relative to the ground at a speed of 27.9 m/s. The ball is caught 62.5 m from the thrower.
The acceleration of gravity is 9.81 m/s^2

I found the time to be 2.492387686 s

How do I go about finding the height of the tallest point in the ball's path?
