A penguin slides horizontally off the edge of an iceberg with a velocity of 6.30 m/s. If the water is 4.50 m below the iceberg, how far from the edge of the iceberg does the penguin land? Answer in units of m. Help pls!!!

What would be the strength of earth's gravitational field at a point where an 80.0 kg astronaut would experience a 80% reduction in weight

In a series circuit the __ is the same at every point

Avertical clean glass piezometer tube has an inside diameter of d = 1 mm and is used to measure pressure in a horizontal pipe carrying water as shown. due to pressure in the pipe, the water at 20c rises into the tube to a height h. if the water pressure in the pipe is p = 500 pa gauge, estimate the height h: (a) without considering surface tension (b) with surface tension (capillary) effects. the contact angle  can be assumed at 30 deg
