Two blocks of A=8kg and B=2kg are connected by a lightensible string that runs over a smooth pully. The 8kg block moves at constant velocity when a 29.6 force pulls it to the right. It experiences a constant frictional force of magnitude 10N as it moves to the right. Calculate the tension and acceleration ​

=force × distance a. work b. velocity c. pressure d. momentum

An open cart is moving along a straight frictionless horizontal track. when rain starts falling vertically into the cart, what happens to the speed of the cart?

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.
