.A coin rolls off the edge of a table. The coin was travelling with a speed of 1.7 m/s. It lands 0.8 m away from the table leg (which is
straight down from the table edge). How high is the table?

If forces acting on an object are unbalanced. true or false

(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?
