Calculate specific heat of liquid if a 450. g iron block is heated to 98.0 c and then droped into a calorimeter with 125 g of unknown liqid at 19.8 c. after 2 minutes the temp inside the calorimeter rise to a maximum of 40.4 c.

The charge on a charged sphere is: a)concentrated at its centerb)distributed uniformly throughout its volumec)clustered on its centerd)distributed uniformly over its surface

How to calculate voltage drop in a series circuit

During the apollo moon missions, astronauts were concerned about the effects of newton's third law of motion when: o a. they ejected waste water, because they were concerned that it would push them off course. o b. they reentered earth's atmosphere, because they were carrying heavy moon rocks. o c. they took off from earth, because a large force was required to generate large acceleration. o d. they detected incoming space debris, because the inertia of the debris could damage their ship.
