you have set a leak rate on your mass spectrometer at 100 pl/min. you introduce a sample of protien isolated from a banded sea snake that has a density of 0.5 ng/pl. you leak your sample into the device for 1 minute. what is the total mass you are detecting?

The diagram below shows a block of mass m=2.0\; \rm kg on a frictionless horizontal surface, as seen from above. Three forces of magnitudes F_1 = 4.0\;{\rm N}, F_2 = 6.0\;{\rm N}, and F_3 = 8.0\;{\rm N} are applied to the block, initially at rest on the surface, at angles shown on the diagram. View Figure In this problem, you will determine the resultant (total) force vector from the combination of the three individual force vectors. All angles should be measured counterclockwise from the positive x axis (i.e., all angles are positive).

Calculate the magnitude of the total resultant force \vec{F}_{\rm r} = \vec{F}_1+ \vec{F}_2 +\vec{F}_3 acting on the mass.

An advertisement claims that a particular automobile can "stop on a dime." What net force would actually be necessary to stop an automobile of mass 860 kg traveling initially at a speed of 58.0 km/h in a distance equal to the diameter of a dime, which is 1.80 cm?

so i used the formula sum of F= (m(vf^2-vi^2))/2x.

is this wrong because i keep on getting the wrong answer. please help.

You always see 4.7K resistors, 4.7uF capacitors, and such. Since 47 is a prime number, this seems very odd (pun intended). Why 47 and not, say, 48 or 50?
