Two water bottles a and b have the same mass (m) and very similar size and shape but are made from different materials (ma and mg respectively) at room temperature. the same amount of boiling water is put into a and b, and then both bottles are closed with screw caps. after 5 minutes, the temperature of water in bottle a is higher than the water in bottle b. we may then conclude that (with your explanation): (a) ma has higher specific heat and the water in a has lower internal energy. (b) ma has lower specific heat and the water in b has higher internal energy. (c) mb has lower specific heat but the water in a and b have the same internal energy. (d) mb has higher specific heat but the water in a has higher internal energy (e) mb and mb have the same specific heat and the water in a and b have the same [10 marks] internal energy

The membrane surrounding a living cell consists of an inner and an outer wall that are separated by a small space. assume that the membrane acts like a parallel plate capacitor in which the effective charge density on the inner and outer walls has a magnitude of 7.0 × 10-6 c/m2. (a) what is the magnitude of the electric field within the cell membrane? (b) find the magnitude of the electric force that would be exerted on a potassium ion (k+; charge = +e) placed inside the membrane.
