A 4.13-kg squid is initially at rest. It then rapidly ejects 0.25 kg of water with a velocity of 10.2 m/s to propel itself. If the squid then experiences a 4.64-N drag force opposing its travel through the water, the squid will move a distance of Blank 1. Calculate the answer by read surrounding text. m before stopping.

A248-g piece of copper is dropped into 390 ml of water at 22.6 °c. the final temperature of the water was measured as 39.9 °c. calculate the initial temperature of the piece of copper. assume that all heat transfer occurs between the copper and the water. remember, the density of water is 1.0 g/m

The force acting on a beam was measured under the same operating conditions and a sample of 5 data points was collected. this process was repeated by 3 observers. the pooled standard deviations of these 3 data sets was 1.21. determine the true mean force using all pooled data (with a 95% probability). the result should look like this: true mean = mean +/- margin of error
