A uniform magnetic field passes through two areas, A1 and A2. The angles between the magnetic field and the normal directions of areas A1 and A2 are 30° and 60°, respectively. If the magnetic flux through the two areas is the same, what is the ratio A1/A2? A. 0.577
B. 0.816
C. 1.00
D. 1.23

The energy released by a chemical reaction can be measured using a calorimeter. when barium hydroxide octahydrate crystals are reacted with dry ammonium chloride inside of a coffee cup calorimeter, the temperature of the 18.00 g of water in the calorimeter decreases from 30.0°c to 8.0°c. the equation for calculating energy absorbed or released by a reaction is: where q is the energy released or absorbed, m is the mass of water in the calorimeter, cp is the specific heat of water, and δt is the observed temperature change. if the specific heat of liquid water is 4.19 j/g·°c, how much energy was absorbed by the reaction?

This is one type of line graph in which the independent variable is time plotted on the x axis and the dependent variable, also numerical, is plotted on the y axis.
