105.00 L 5.00 kg 0.00 N Fluid Oil Water Weight of 5.00 kg wood block = 49 N Step 2: Place the wood block in the water and notice that it floats. When the wood block rests on the ground, the downward gravitational force is balanced by an upward normal (“contact") force. When floating, the gravitational force is still there, but the normal (contact") force is not. The force exerted by the fluid is the buoyant force (B). When floating,...

2. Determine the volume of the liquid in the tank.
1.29 A tank contains 500 kg of a liquid whose specific gravity is 2. Determine the volume of the liquid in the tank. 130 Clouds can weigh thousands of pounds due to their liquid water content. Often this content is measured in grams per cubic meter g/m3.Assume that a cumulus cloud occupies a volume of one cubic kilometer,...

1. A dairy processing plant needs a steady flow of 100 L of water per minute from 9:00am to 5:00pm, 7 days a week. They use no water outside of those hours. To meet their demand, they would like to pump water at a constant rate to rooftop storage tanks, 24 hours a day a. (20 pts) How much storage (i.e., how much balance volume) will be required? b. (1 0 pts) The roof can only support 1,500 kg per...

I need help with lab this week. I have posted theory and procedures to the lab. The questions with ????????? are the ones I need help with. Please Help!! Thank you Theory Density is defined as mass per unit volume that has a metric unit of kg per cubic meter. Grams per cubic centimeter i.e. g/cm3 actually is widely used as the unit of density. The densities for objects with regular shapes are easily to be determined. For objects with...

1. (20 Marks) An object has an L-shape and can be treated as 2 beams fixed together at right angle. Beam 1 (B) has a weight wi = 180 N and a length Li-2.00 m and Beam 2 (B) has a weight w2 90.0 N and a length L2- 1.00 m. This object is hinged by its corner O to the ground via a hinge that allows it to rotate clockwise counter clockwise, when possible. B2 rope B2 0 Figure...
