What is the resulting density when you mix 5.0 L of ethyl alcohol and 12.0 L of water?
Find tbe density of air at 0°C and 1.013 x 105 Pa. One mole of air may be assumed to be 79 percent nitrogen (Mnitrogen= 28.0 g) and 21 percent oxygen (Moxygen = 32.0 g).
A rectangular block on material is subjected to a tensile stress of 100 N/mm2 on one plane and

a truck P (900kg)starts from rest runs down a frictionless slope from point a to b which is 101.4 meters, from a height at point a of 33.8 meters to b 0 meters,truck P collided with truck Q (337,5kg)at point b and continues to move with a speed of 19,5 m.s1.,what is tuck Q velocity after collision
a 3.5-kg block rest on a horizontal top. A cord is attached to this block, the cord passing over a pulley at the edge of the table. At the end of the cortex is hung another block weighing 5 N. Determine the tension in the cord and the distance the blocks move after 2 seconds.
a 12-kg block is acted upon by two forces that are in opposite direction, one a 540 Newton and the other of 1260 N. Determine the acceleration produced. How is the direction of the acceleration related to the forces?
A uniform cube is free to turn about one edge which is horizon. Find in terms of a seconds pendulum the length of the edge , so that it may execute a complete oscillating in which secs
A 20kg load is dragged along a horizontal surface, if the coefficient of kinetic friction between the load and the surface is 0.23, what is the magnitude of the force applied at angle 30° above the horizontal that results to the load having an acceleration of 0.75m/s² (g= 9.8m/s²)
