Large and small numbers are often best entered in exponential notation. for example, the mass of the earth is 5.98x1024 kg and the mass of an electron is 9.11x10-31 kg. canvas does not have the capability to handle scientific notation. we will include the power of 10 with the units needed in the answer. the charge of an electron is -1.60x10-19 c. determine the charge to mass ratio of the electron (in 1011 c/kg). (hint: divide the electron's charge by its mass; the answer is a negative number with a positive exponent)

Ateam of astronauts is on a mission to land on and explore a large asteroid. in addition to collecting samples and performing experiments, one of their tasks is to demonstrate the concept of the escape speed by throwing rocks straight up at various initial speeds. with what minimum initial speed vesc will the rocks need to be thrown in order for them never to "fall" back to the asteroid? assume that the asteroid is approximately spherical, with an average density p 3.84 x108 g/m3 and volume v 2.17 x 1012 m3 recall that the universal gravitational constant is g 6.67 x 10-11 n m2/kg2

Phase changes are chemical changes. true or false

Point charges q1 = 51 µc and q2 = −27 µc are placed 1.0 m apart, with q2 on the right. what is the force (in n) on a third charge q3 = 19 µc placed midway between q1 and q2? (assume the positive direction is to the right. indicate the direction with the sign of your answer.)
