    Microwave oven: Many molecules (such as those of water) are electric dipoles, meaning that they have a partial positive charge at one end and a partial negative charge at the other, and therefore rotate as they try to align themselves with the alternating electric field of the microwaves...

    chem mcq!

    Its D in term of movement of particles: (for constant volume, ie, closed container) When temperature is increased, the molecules gain kinetic energy and their motion increases. Their frequency of effective collision with one another and the walls of the container increases. Therefore, pressure...

    because the moon's velocity is high, the centripetal force with which it rotates around the earth is also big. So moon has the higher tendency to keep its orbit and rotate around the earth.

    physics

    and also that moon is travelling too fast. 1] The relative velocity is large, while the gravitational attraction is small. The two objects, as they near each other at high speeds, will influence each other gravitationally - they'll deflect their straight paths towards each other. But their v...

    physics

    yes that will happen but in case of moon, gravitational force gives rise to centripetal force which keeps the moon in orbit instead of colliding with the earth.

    help in chemistry mcq

    there may be other ways but this one is also correct. 24000 cm^3 occupies 1 mole so 120 cm3 occupies 1/240000 x 120 moles If some other way also comes into my mind i'll post here.

    yup. That is why when you are preparing for MCAT, take test tuition.
