A student redid the experiment of mixing room temperature water and warm water. This time, she used half the original amount of warm water. How will
the final temperature be different?
A. It will be lower, because the amount of water in the mixture will be
less.
B. It will be higher, because all parts of the mixture will end up at the
same temperature.
C. It will be the same, because all parts of the mixture will end up at
the same temperature.
D. It will be lower, because less thermal energy is transferred to the
room-temperature water.

Aprojectile is launched from ground level with an initial velocity of v 0 feet per second. neglecting air resistance, its height in feet t seconds after launch is given by s equals negative 16 t squared plus v 0 t. find the time(s) that the projectile will (a) reach a height of 192 ft and (b) return to the ground when v 0equals112 feet per second. (a) find the time(s) that the projectile will reach a height of 192 ft when v 0equals112 feet per second. select the correct choice below and, if necessary, fill in the answer box to complete your choice.

Two technicians are discussing a resistance measurement between the can-h and can-l wires. technician a says this measurement should be done with the ignition switch in the "run" position. technician b states that a measurement of 0 ohms indicates an open in the network. which technician is correct?
