You are skating down a hill with no means of measuring velocity: You can measure however, that the downhill distance is 100 m and it takes 10 s to rerch the bottom. If you begin with a 0.5 m/s velocity what will the final velocity at the bottom of the
hill be?

Why does the input force have to be greater than the force needed to lift the bale?

What color would an object that reflects green and blue light appear to be in white light? a. blue b. cyan c. magenta d. black

(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?
