A 410 turn solenoid of length 39.5 cm and radius 2.80 cm carries a current of 4.90 A. Find the following. (a) the magnetic field strength inside the coil at its midpoint mT (b) the magnetic flux through a circular cross-sectional area of the solenoid at its midpoint

Assume you measured the mass of the cart to be (500 ± 1) g and the mass of the additional mass you put on the cart to be (500 ± 1) g as well. since the scale you are using in the lab cannot measure objects heavier than 600g you will have to sum up individual pieces and propagate the error. so what would be the mass and the standard error of the cart and the mass

He latent heat of vaporization for ethyl alcohol is 854 j/g. the amount of energy, rounded to the nearest whole number, needed to change 5.20 grams of ethyl alcohol from a liquid to a gas is
