Kato must write 60 percent of a 20-page report by tomorrow. Kato wants to determine the number of pages that he needs to write by tomorrow. Kato’s work is shown below. Step 1: Write 60 percent as a ratio. StartFraction part Over whole EndFraction = StartFraction 60 Over 100 EndFraction Step 2: Write an equivalent ratio that has the answer in the numerator and 20 in the denominator. Step 3: 100 divided by 20 = 5 Step 4: 60(5) = 180 What mistake did Kato make? In Step 1, Kato should have written the ratio as StartFraction 100 Over 60 EndFraction. In Step 2, Kato should have put 20 in the numerator. In Step 3, Kato should have multiplied 100 by 5. In Step 4, Kato should have divided 60 by 5.

During physical science, ms. greene challenged her students to produce an energy transformation. james and jill wrapped a 4-inch nail with a coil of fifty turns of wire. they connected one end of the coil to one terminal of a knife switch. they connected the other terminal of the knife switch to the battery. finally, they connected the end of the coil to the other terminal of the battery. james held the tip of a 1-inch nail near the flat end of the 4-inch nail. jill closed the knife switch quickly and then opened it. the 1-inch nail was pulled toward the 4-inch nail. what is the best explanation of why the nail moved? a) electrical energy was converted to mechanical energy in the 1-inch nail. b) the 4-inch nail became an electromagnet and the magnetic force attracted the 1-inch nail. c) the electric current in the 4-inch nail was converted to mechanical energy in the 1-inch nail. d) the 4-inch nail had a positive charge and the 1-inch nail had a negative charge. opposites attracted.

Agas expands from an initial volume of 0.040 m^3 and an initial pressure of 210 kpa to a final volume of 0.065 m^3 while its temperature is kept constant. how much work is done by the system?
