In Part 1 of the lab activity, you did not assume that the center of mass was at the 50 cm mark. Instead, you determined the location of the center of mass of the meter stick to eliminate this source of error. Let's say that the actual center of mass is at the 49 cm mark. If you did not measure this and assumed it was at 50 cm, what kind of error would have been introduced

Alead ball is dropped into a lake from a diving board 5m above the water . it hits the water with a certain velocity and then sink with constant velocity in bottom . it reaches the bottom 5 second after it is dropped if g= 10m/s2 . find depth of the lake and average velocity of the ball ?

Acarpenter builds an exterior house wall with a layer of wood 2.9 cm thick on the outside and a layer of styrofoam insulation 2.3 cm thick on the inside wall surface. the wood has k=0.080w/(m⋅k), and the styrofoam has k= 0.010 w/(m⋅k). the interior surface temperature is 19.0 ∘c , and the exterior surface temperature is -15.0 ∘c . a.)what is the temperature at the plane where the wood meets the styrofoam? celsius b.)what is the rate of heat flow per square meter through this wall? /m^2

The process of predicting values that extend beyond the range of data points is called absolute value extrapolation interpolation prediction for any given: )
