Amethod for determining the thermal conductivity k and the specific heat of a material is illustrated in the sketch. initially the two identical samples of diameter 60 mm and thickness 10 mm and the thin heater are at a uniform temperature of 23.00°c, while surrounded by an insulating powder. suddenly the heater is energized to provide a uniform heat flux on each of the sample interfaces, and the heat flux is maintained constant for a period of time, . a short time after sudden heating is initiated, the temperature at this interface is related to the heat flux as

The coulomb's law explains which of the following? select all the force between two charged objects is inversely proportional to the charge on each object. the force between two charged objects is directly proportional to the charge on each object. the force between two charged objects is directly proportional to the distance separating them. the force between two charged objects is inversely proportional to the square of the distance separat coulomb's law is similar to newton's 2nd law. if the force between two objects is f and the charge on both objects is doubled, the new force between the would now be 2f. if the force between two objects is 2f and the distance separating them is doubled, the new force between the objects would now o the be zf.

It's a snowy day and you're pulling a friend along a level road on a sled. you've both been taking physics, so she asks what you think the coefficient of friction between the sled and the snow is. you've been walking at a steady 1.5m/s, and the rope pulls up on the sled at a 32 ∘ angle. you estimate that the mass of the sled, with your friend on it, is 65 kg and that you're pulling with a force of 80 n .
