The rate of the quantities provided in the table that will change when a person runs outside on a windy day, from the following options: a. The work done by the drag force might increase because wind can exert a greater force than stationary air. b. Cooling by evaporation might increase because the wind will spend up the evaporation process. c. Cooling by convection might increase in the same way as with forced convection. d. Cooling by radiation might increase because the temperature of skin surface will decrease. e. All of the above f. (a)-(c) are correct, but not (d).

When current is flowing through the coil, the direction of the torque can be thought of in two ways. Either as the result of the forces on current carrying wires, or as a magnetic dipole moment trying to line up with an external field (e.g. like a compass). Note: the magnetic moment of a coil points in the direction of the coil's magnetic field at the center of the coil. d) Forces: We can consider the left-most piece of the loop (labeled ○) as a short segment of straight wire carrying current directly out of the page at us. Similarly, we can consider the right-most piece of the loop (labeled ) as a short segment straight wire carrying current directly into the page, away from us. Add to the picture below the two forces due to the external magnetic field acting on these two segments. Then describe how these two forces give a torque and determine if the torque acts to rotate the loop clockwise or counterclockwise according to this picture? B

If the mass of substance (1 kg), initial temperature (125˚C), the final temperature (175˚C) and the total volume of a closed container (1 m3) remains constant in two experiments, but one experiment is done with water ( ) and the other is done with nitrogen ( ). What is the difference in the change in pressure between water and nitrogen?
