In the lab, you have nails with mass Mn and temperature Tn. You submerge those nails in the water with mass Mw and temperature Tw. Specific heat capacities of nails Cn and water Cw are Cn = 0.12 cal/gC Cw = 1.00 cal/gC Presume no energy loss (all energy transfer is only between water and nails). Find the resulting temperature of nails in the water after temperature is equalized given the following values: Mn = 138 g Tn = 110 C Mw = 135 g Tw = 31 C Enter 2 digits after decimal point. Hint: develop a formula first using Q=mcΔT twice and conservation of energy concept. Look at resulting formula to decide if you can use non-standard units (T in degrees C, mass in grams and C in cal/gC).

An ambulance emits a frequency of 450 hz from its siren. what frequency is heard by a man as the ambulance moves toward him? less than 450 hz more than 450 hz 450 hz 0 hz

How do the measurements of charge at the different locations on the sphere compare to each other? the charge measurements are different at all locations on the sphere. the charge measurements are virtually not the same at all locations on the sphere except for the charge at the very top and at the very bottom that are equal. the charge measurements are virtually the same at all locations on the sphere except for the charge at the very top. at the top, the conductive sphere has a small disk that is made of different material. the charge measurements are the same at all locations on the sphere. what happens to the charge on the conductive sphere when it is connected to a source of charge such as the electrostatic voltage source? nothing will happen because no charge goes around the surface of the sphere. the charge on the conductive sphere spreads out over the surface of the sphere; being greater in some specific locations on the sphere. the charge on the conductive sphere spreads out uniformly over the surface of the sphere. the charge on the conductive sphere spreads out non-uniformly over the surface of the sphere.
