The earth spins on its axis and also orbits around the sun. for this problem use the following constants. mass of the earth: 5.97 × 1024 kg (assume a uniform mass distribution) radius of the earth: 6371 km distance of earth from sun: 149,600,000 km calculate the rotational kinetic energy of the earth due to rotation about its axis, in joules.

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.

Large electric fields in cell membranes cause ions to move through the cell wall. the field strength in a typical membrane is 1.0 x 10 7 n/c. what is the magnitude of the force on a calcium ion with charge +e? what is its acceleration? is it possible for a particle with the same charge as as calcium to have a different acceleration if placed at this location? what would change the acceleration: mass of the particle? diameter of the particle?

When barack obama was running for president, at a campaign stop he tried to bowl, something he isn't very good at. the media loved it because he threw a gutter ball while they were all watching. this is an example of:
