Two copper wires (H & L) each with a length of 1.8m are placed perpendiculary across a 0.3 Tesla magnetic field. Wire H has a current of 2.2A flowing through it;
while wire L has a current of 4.1A flowing through it.
1) Which wire (H or L) experiences a larger force?
2) What is the value of the larger force (in Newtons)? (round your answer to 2
decimal places and do not include units)

Which best describes how fluids change as they travel through different portions of the convection currents? they change to solids at the outer portion of the convection currents. they change to solids at the inner portion of the convection currents. they become more dense at the outer portion of the convection currents. they become more dense at the inner portion of the convection currents

The experiment done in lab is repeated, using a ball that has unknown mass m. you plot your data in the form of f 2 versus m/l, with f in rev/s, m in kg, and l in m. your data falls close to a straight line that has slope 3.19 m/(kg · s2). use g = 9.80 m/s2 and calculate the mass m of the ball.

The items in the following list are all units of matter. which is the smallest unit that retains the properties of the matter? a.) atom b.) compound c.) electron d.) element
