The si unit of force, the kilogram-meter per second squared (kg · m/s2), is called the newton (n). find the dimensions and the si units of the constant g in newton's law of gravitation f = gm1m2/r2. (for the dimension use l for length, m for mass, and t for time. for the units use m for meters, kg for kilograms, and s for seconds.)

(2) (a) you have a simple circuit that consists of only a battery (δvbat=1.5v) and two resistors with resistance r1=10ω and r2=5ω, connected in series with each other. what is the current running through the battery? (b) you re-arrange your circuit so now r2 is attached in parallel to r1 rather than in series. what is the current running through the battery? (c) you add an additional resistor r3=7ω on the same branch as r2. what is the current running through the battery? (d) what is the power dissipated in r3?

The voltage applied across a given parallel-plate capacitor is doubled. how is the energy stored in the capacitor affected?
