German physicist werner heisenberg related the uncertainty of an object's position (δx) to the uncertainty in its velocity (δ δx≥ℎδ where ℎ is planck's constant and m is the mass of the object. the mass of an electron is 9.11×10−31 kg. what is the uncertainty in the position of an electron moving at 4.00×106 m/s with an uncertainty of δ=0.01×106 m/s?

Aprojectile is launched from ground level with an initial velocity of v 0 feet per second. neglecting air resistance, its height in feet t seconds after launch is given by s equals negative 16 t squared plus v 0 t. find the time(s) that the projectile will (a) reach a height of 192 ft and (b) return to the ground when v 0equals112 feet per second. (a) find the time(s) that the projectile will reach a height of 192 ft when v 0equals112 feet per second. select the correct choice below and, if necessary, fill in the answer box to complete your choice.
