A 0.05 g bug collides with the windshield of a motorcyclist's helmet as the cycler acclerates down the road at a rate of 10 m/s2, if the helmet exerts a force of 1.5 N on the bug, what is the force the bug exerts on the helmet? 1.5 N
0.0005 N
0.25 N
Cannot be degermined

The record distance in the sport of throwing cowpats is 81.1 m. this record toss was set by steve urner of the united states in 1981. assuming the initial launch angle was 45° and neglecting air resistance, answer the following. (a) determine the initial speed of the projectile. m/s

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.

Which property is expressed in distance units? o a. period o b. wavelength o c. speed o d. frequency
