Bonjour, j’ai besoin d’aide Montrer que la pression à 50 m de profondeur dans l'eau (deau = 1) est de 6 bar sachant
que la pression au niveau de la mer est de 1 atm.

The velocity of car is 80.0 miles per hour. what is the velocity of car in meters per second? (1 km -0.621 miles) m/s

Wavelength,frequency,and energy are related.what happens to a wave as it’s wavelength gets shorter?

Total solidification times of three casting geometries are to be compared: a sphere, a cylinder, in which the length-to-diameter ration - 1.0, and a cube. volume = 1000 cm^3 for all three shhapes, and the same casting alloy is used. a) determine the solidification times of each geometry b) based on the results of part (a), which geometric element would make the best riser? c) if the mold constant = 3.5 min/cm^2 in chvorinov's rule, compute the total solidification time for each casting.
