Sure I can do zombies as an idea! I have some good lyrics so far, and its to the beat of a pretty popular song now so I think It will do good. But my only concern is that I don't want the lyrics/idea of the video to seem very obtuse and random...like I have a verse where I explain energy...

Thanks so much!

So elastic collisions end up being it not sticking together... oooooohohhhh okay... J=Ft= change p F=changep/t f=m(vf-vi)/t p=m(vf-vi)/t / a I think I got it... Is it 12,290.9 Pascals?

In a period of 1.1 s, 5.0 x 10^23 nitrogen molecules strike a wall of area 9.0 cm^2 . If the molecules move at 260 m/s and strike the wall head on in a perfectly elastic collision, find the pressure exerted on the wall. (The mass of one N2 molecule is 4.68 10-26 kg.) Molar mass=mass of...

Is there anyway to find the velocity of the air stream?

the density of air at is 1.2 kg/m^3 at 20 degrees centigrade and 1 atm.

An airplane is cruising at an altitude of 10 km. The pressure outside the craft is 0.292 atm; within the passenger compartment, the pressure is 0.97 atm and the temperature is 20°C. A small leak occurs in one of the window seals in the passenger compartment. Model the air as an ideal fluid to...

Okay that makes a lot more sense! so now i have: pg(h1+h2)= 1/2p(v1^2 (a1v1/a2)^2) solved for v1: V1= (2(h1+h2))/(1-(a1^2/a2^2))^(1/2) and I plug in v1 into V1A1= Q and get (2(h1+h2))/(1-(a1^2/a2^2))^(1/2)*(a1)=Q I don't know how to solve for a2 now... haha But the one...

1. The inside diameters of the larger portions of the horizontal pipe are 2.90 cm. Water flows to the right at a rate of 2.00 10-4 m3/s. Determine the inside diameter of the constriction. 2. P=P0 + pgh a1v1=a2v2 P + pgh + 1/2pv^2 = constant 3. Since the volumetric flow rate...

So I would get: \left( \frac{2 \pi }{T }\right)^2 (L)= {g} Is that correct?

This is one question that's giving me a bit of trouble to handle. The Period of a pendulum is given by the following equation: where T= period of pendulum (seconds) L= Length of pendulum (meters) g= acceleration doe to gravity (meters per second2) Solve this equation in terms of L, T...
