Agenerator can be made using the component of earth’s magnetic field that is parallel to earth’s surface. a 140-turn square wire coil with an area of 4.22 ×10−2 m2 is mounted on a shaft so that the cross-sectional area of the coil is perpendicular to the ground. the shaft then rotates with a frequency of 21.4 hz. the horizontal component of the earth’s magnetic field at the location of the loop is 2.00 ×10−5 t. calculate the maximum emf induced in the coil by earth’s magnetic field

A50.0-n box is sliding on a rough horizontal floor, and the only horizontal force acting on it is friction. you observe that at one instant the box is sliding to the right at and that it stops in 2.25 s with uniform acceleration. what magnitude force does friction exert on this box

Place me with this question is my last question

Use henry's law and the solubilities given below to calculate the total volume of nitrogen and oxygen gas that should bubble out of 1.7 l of water upon warming from 25 ˚c to 50 ˚c. assume that the water is initially saturated with nitrogen and oxygen gas at 25 ˚c and a total pressure of 1.0 atm. assume that the gas bubbles out at a temperature of 50 ˚c. the solubility of oxygen gas at 50 ˚c is 27.8 mg/l at an oxygen pressure of 1.00 atm. the solubility of nitrogen gas at 50 ˚c is 14.6 mg/l at a nitrogen pressure of 1.00 atm. assume that the air above the water contains an oxygen partial pressure of 0.21 atm and a nitrogen partial pressure of 0.78 atm.
