Asolid object heated to 120°c is placed inside a container of water at 33°c. what is the best explanation of the resulting change in temperature? a) the temperature of both the water and solid will decrease. b) the temperature of the solid will decrease and the water will decrease. c) the temperature of the water will increase; the temperature of the solid will decrease. d) the temperature of the water will remain constant; the temperature of the solid will decrease.

Ameter stick is pivoted at the 0.50-m line. a 3.0-kg object is hung from the 0.15-m line. where should a 5.0-kg object be hung to achieve equilibrium (the meter stick oriented horizontal and motionless)?

Acertain radio station broadcasts radio waves that have a wavelength of 298cm what is its broadcast frequency?

Beryl states that insulation with the smallest possible thermal conductivity is best to keep a house warm in winter, but worst for keeping a house cool in summer. sapphire insists the reverse is true: low thermal conductivity is good in the summer, but bad in the winter. which one, if either is correct? a. beryl, because low thermal conductivity results in low heat transfer. b. beryl, because low thermal conductivity results in high heat transfer. d. sapphire, because low thermal conductivity results in high heat transfer. e. neither, because low heat transfer is desirable both in summer and in winter.
