you can also do a blown in insulationin my attic i put fiberglass bats in between the joist, then put the blown in insulation over the topin la r19 is probably finethe higher the r value the higher the insulation factora lot of newer homes in my area are using r30-r35.
1- WFd W4020 W800 Joules Sorry my first answer was wrong.I fixed it! 2- ma300N So F300N W3003 (cos 0) because F and d are in the same directionW900Joules (or 900 kg (m^2/s^2)) 3-W100 The person wasted his/her time pushing But the person burned some calories by doing soW/Fd 24000/200012meters If your stuck remember you can substitute F for ma Wmad (lol)
