While exploring a sunken ocean liner, the principal researcher found the absolute pressure on the robot observation submarine at the level of the ship
Calculate the drift velocity of electrons in a copper wire given the current flowing in it, its diameter and density.
A hollow metal cube made of aluminum has an outer-length of 12cm and an inner length of 8cm each "side" of the outside of the cube is 12cm long
Assuming an average sea-level pressure of 1000hPa, what is the mass of the atmosphere? assume that the earth is as sphere with radius 6400km.
A dam to create a large fresh water lake is constructed. It will be approximately 14 meters deep. A horizontal pipe 1.2 meters long and 4 cm in diameter.
Four tanks of gas, labeled A, B, C, and D are stored under different conditions. The gases in these tanks are then placed into a fifth, tank E.
A ball is thrown directly downward, with an initial speed of 8.50 m/s, from a height of 31.0 m. After what time interval does the ball strike the ground?
What are their locations at that time? (If there is only one location, use NA as one of the answers. If there are two locations, enter the smaller location firs
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.
If the ball bounces straight up and returns to the floor 2.5 s after first striking it, what was the ball's greatest height above the floor?
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

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
How far from Earth must a space probe be along a line toward the Sun so that the Sun's gravitational pull on the probe balances the Earth's pull?
Purpose: In this experiment you will use a current-carrying loop to determine the horizontal component of the earths magnetic field for our locality.
The gravitational force on a body located a distance R from the center of a uniform spherical mass is due solely to the mass lying at distance
