What is the difference chemistry and physics

You are still fascinated by the process of inkjet printing, as described in the opening storyline for this chapter. you convince your father to take you to his manufacturing facility to see the machines that print expiration dates on eggs. you strike up a conversation with the technician operating the machine. he tells you that the ink drops are created using a piezoelectric crystal, acoustic waves, and the plateau-rayleigh instability, which creates uniform drops of mass m = 1.25 ✕ 10−8 g. while you don't understand the fancy words, you do recognize mass! the technician also tells you that the drops are charged to a controllable value of q and then projected vertically downward between parallel deflecting plates at a constant terminal speed of 20.0 m/s. the plates are ℓ = 2.15 cm long and have a uniform electric field of magnitude e = 6.40 ✕ 104 n/c between them. noting your interest in the process, the technician asks you, "if the position on the egg at which the drop is to be deposited requires that its deflection at the bottom end of the plates be 0.17 mm, what is the required charge on the drop (in c)? " you quickly get to work to find the answer. (neglect the force of gravity.)

Kent is twirling a ball attached to a string in a clockwise direction. if kent lets go of the string, which of the following describes the motion that the ball will take if there are no gravitational forces influencing the motion of the ball? a. it will curve down and then turn back up. b. it will fall straight to the ground. c. it will continue in a straight line. d. it will curve up and then fall to the ground.

As air mass cools, water will condense when: a) the humanity reaches the dew point. b) the relative humidity equals the standard humidity. c) the air pressure reaches the atmospheric pressure. d) the temperature reaches the dew point.
