he answered 94% correctly if you have 94/100 then you just need to put down 94 and then the percent sign after % represents 100 (note the 2 zeros in the percent sign)
5/5-2/5 = 3/5 1/5 + 1/5 + 1/5 = 3/5 0.2 + 0.2 + 0.2 = 0.6 So 1/3 would be equal to 0.2 which means that after the farmer gave away 1/3 of his cattle he would have 40% left or 2/5.
Volume 1 = 54.2 L Pressure 1 = 1150 mmHg Volume 2 = ? Pressure 2 = 3450 mmHg 54.2 L * (1150/3450) = 18 L 1150/3450 because volume should get smaller since pressure is increasing
24-20 gives the number of yards remaining. Then multiply this by 3 because there are three feet in a yard. This results in 12 feet.
Thank you. I didn't know I could do that, but it did give me the right answer.
Sorry What is the force Fvec on a 1.2 nC charge placed at the midpoint?
Ke = .5mv^2 so the ke is .5(26)(8.4^2)= 917.28
1020 N/C
