1. You own a mechanically ventilated swine facility. The dry bulb temperature inside the facility is 50 degrees F and outside is only 30 degrees F. Inside you have a relative humidity of 70% and outside the relative humidity is 20%. To keep the humidity from getting any higher you need to remove 12 gallons of water per hour from the facility with the ventilation air. At what rate (cfm) must the fans pull inside air out of the building? 2. A producer has a barn for sheep and lambs. The producer wants to use evaporative cooling to cool the barn. If the outside air has a dry bulb temperature of 90 degrees F and a relative humidity of 40%, what is the lowest temperature that the producer can get using the evaporative cooler?

When a resistor with resistance r is connected to a 1.50-v flashlight battery, the resistor consumes 0.0625 w of electrical power. (throughout, assume that each battery has negligible internal resistance.) what power does the resistor consume if it is connected to a 12.6-v car battery? assume that r remains constant when the power consumption changes.

The coulomb's law explains which of the following? select all the force between two charged objects is inversely proportional to the charge on each object. the force between two charged objects is directly proportional to the charge on each object. the force between two charged objects is directly proportional to the distance separating them. the force between two charged objects is inversely proportional to the square of the distance separat coulomb's law is similar to newton's 2nd law. if the force between two objects is f and the charge on both objects is doubled, the new force between the would now be 2f. if the force between two objects is 2f and the distance separating them is doubled, the new force between the objects would now o the be zf.
