Liz puts a 1 kg weight and a 10 kg on identical sleds. she then applies a 10n force to each sled. which does not explain why the smaller weight accelerate faster? a) the larger mass spends more force overcoming inertia. b) the smaller weight exerts less frictional force to overcome. c) the acceleration depends directly on the mass of the object. d) the motion of the sled relates to action of unbalanced forces.

Alinearly polarized electromagnetic wave has an average intensity of 196 w/m^2. this wave is directed towards two ideal polarizers (in real polarizers, transmission is also effected by reflection and absorption). polarizer a is oriented with its transmission axis at an angle of θ_1=20.8∘ with the incident electric field. polarizer b has its axis at an angle of θ_2=63.0∘ with the incident electric field. what is the average intensity of the wave after it passes through polarizer a? what is the average intensity of the wave after it passes through polarizer b? suppose that the two polarizers a and b are interchanged. what would the average intensity be after passing through both polarizers?
