Mike and Brandon carry a log that weighs 644N. The trunk is 8.2m long and its weight is evenly distributed (you can consider the center of mass right in the middle). If Mike is 1.5m from the left end and Brandon is 2.9m from the right end, find the force that Mike has to exert to keep the trunk in balance. He considers that both Mike and Brandon exert forces directed completely upwards. Write the result in Newtons with two decimal places.

What is the single most important equation in all of physics?

Acommon technique in analysis of scientific data is normalization. the purpose of normalizing data is to eliminate irrelevant constants that can obscure the salient features of the data. the goal of this experiment is to test the hypothesis that the flux of light decreases as the square of the distance from the source. in this case, the absolute value of the voltage measured by the photometer is irrelevant; only the relative value conveys useful information. suppose that in part 2.2.2 of the experiment, students obtain a signal value of 162 mv at a distance of 4 cm and a value of 86 mv at a distance of 5.7 cm. normalize the students' data to the value obtained at 4 cm. (divide the signal value by 162.) then calculate the theoretically expected (normalized) value at 5.7 cm.
