According to Newton's Second Law of Motion, the acceleration experienced by an object is… (Hint: You may want to rearrange the formula that represents the second law so that the acceleration is isolated. Inother words, a = ?)

A.) directly proportional to both the mass of the object and the force applied to the object.

B.)directly proportional to the mass of the object and inversely proportional to the
force applied to the object.

C.)inversely proportional to both the mass of the object and the force applied to
the object.

D.)inversely proportional to the mass of the object and directly proportional to the
force applied to the object.

How much work would a child do while puling a 12-kg wagon a distance of 3m with a 22 n force directed 30 degrees with respect to the horizontal? (a) 82j (b) 52j (c) 109j (d) 95j

Astudent is performing an experiment comparing sound and light waves. the student gathers the following data. what conclusion does the student most likely make based on this data? light waves always travel the same speed; however, the speed of sound is determined by the medium that it travels through. all sound waves always have the same energy, so the temperature of the medium does not affect wave speed. light needs to vibrate particles, so it travels fastest in tightly packed solids, while sound does not need a medium, so it travels fastest in a gas. tightly packed particles in solids slow down the light waves; however, sound waves make particles bounce into each other, so they travel faster in solids.

Which compound is held together by the electrostatic force between two ions? a. co2 b. cci4 c. h2s d. mgf2
