Question

Two objects are made of different material but have exactly the same volume. If both object are completely submerged in water, upon which object is the bouyant force greater? a. The object that is less massive b. The object that is more massive c. The buoyant force is the same on both objects d. Not enough information The density of liquid water at 4 degree C is slightly greater than the density of ice. a. True b. False The electronic structure of a material, the particular, the outer valence electrons a. Determines the melting and boiling points of the material b. Determines whether the material is a good heat conductor c. Determines whether the material is a good electrical conductor d. Determines whether a material is brittle e. All of the above A 50 gram chunk of steel initially at a temperature of 80 degree C is dropped into an insulated container with of ethanol. The initial temperature of the ethanol is 20 degree C. Assume that the system is insulated so that escapes to the environment. When the two materials reach thermal equilibrium, the final temperature combined materials will be a. 50 degree C b. More than 50 degree C is c. Less than 50 degree C is Which of the following is a method of heat transport that involves the movement of warm moles liquid from one region to another? a. Convection b. Conduction c. Radiation How much will a 12.0m steel rod lengthen when the temperature changes from 15 degree C to 25 degree C a. 1.20 times 10^-4m b. 18 times 10^-4 m c. 1.56 times 10^-3m How much heat is required to raise the temperature of 200 gm of water from 20 degree C to 50 degree C a. 4000 calories b. 10000 calories c. 6000 calories

Explanation / Answer

5 option C the buoyant force on both will be same for example we take cork ball and aluminium ball of same volume the cork will pop up whreas the aluminium ball will sink down, their behaviour will be different but the buoyant force upon them will be equal.
