You are looking down at the earth from inside a jetliner flying at an altitude of 9300 m. The pupil of your eye has a diameter of 2.00 mm. Determine how far apart two cars must be on the ground if you are to have any hope of distinguishing between them with the following lighting. red light (wavelength = 665 nm in vacuum)and vio
Question: At a certain location, the horizontal component of the earth's magnetic field is 4.6E-5 T, due north. A proton moves eastward with just the right speed, so the magnetic force on it balances the weight. Find the speed of the proton.
Briefly, discuss the aspects of electrical safety and shock.
Analysis of the spectrum of X for the surface of solid objects can, when compared to samples of different substances on Earth, reveal the surface composition of that body. What is X?
The alignment Sun, Earth, and Moon in the order will not necessarily result in a X being observed. What is B?

A mass of 100kg weighs 980.6N at sea level. Estimate the weight of this body at the top of a mountain 5km high. Assume that the mean diameter of the earth is 12742km.
"How far above the Earth's surface will the acceleration due to gravity be a quarter of what it is on the surface?" I tried to use the g' = (G * m) / r^2 equation (with the mass of the earth as "m") because it was used with a somewhat similar problem in my book about the value of g on the top of Mount Everest, but I came up w
A 75.6 kg person stands on a scale in an elevator. What does the scale read (it reads mass units, not weight units) when the elevator is accelerating downward at 3.00 m/s^2?"

A.) Draw a space-time diagram for a piston moving back and forth in a cylinder. (use the line of motion of the piston for the space coordinate)...a description of how one might make such a diagram would be sufficiant. b.) Clocks A and B are synchronized and the clock A is sent on ten fast earth orbits and brought back. Now that

A projectile of mass m is fired from the surface of the earth at an angle A from the vertical. The initial speed Vo is equal to the square root (GMe/Re). How high does the projectile rise? Neglect air resistance and the earth's rotation. (Hint: It is probably easier to apply the conservation laws directly instead of using orbit
