I calculated tan and sin (theta) for a physics lab experiment -- two-slit interference I had to use this equation y = L tan (theta), with y = 0.25 and L = 2 and tan (theta) came out to be 7.12 in degrees and 0.1243 in radians. I found sin (theta) by using the triangle for X^2 ...
I need a 1.00 W motor to push a garbage compactor so that it squishes some garbage. The garbage has a spring constant of 49.7 N/m. If I am going to squish it 30 cm, determine how much time the compactor takes.
What is the wavelength of waves transmitted by an AM radio station operating at a frequency of 840 kilohertz? Calculate the energy of a photon whose frequency is 2450 megahertz What is the difference in energy for a photon of ultra-violet radiation, wavelength 319 nm and a pho...
A wolf us chasing a rabbit.Graph the wolf's motion using the following data: 15 m\s at 0 s,10 m\s at 3 s,1 m\s at 4 s,and 0 m\s at 5 s.What does the graph tell you???
Could someone explain how to graph the following problem? I don't quite understand what "Graph H for 0 ≤ t ≤ 3 and 300 ≤ H ≤ 340" is asking me to do... The National Oceanic and Atmospheric Administration (NOAA) has been measuring atmospher...
true or false The Great Migration was a large-scale movement of hundreds of thousands of southern African Americans to Weswtern farms.
exactly. This is all I was given. Possibly SumOf t = T(exp)*length* sin(theta) - W(hang) * length * sin(phi) - W(boom) * L(exp) * sin(phi) = 0 but im not sure.
The torques acting on the crane boom can be computed about anaxis passing through the top of the boom. (this is the place wherethe spring scale and mass hanger connect to the boom) apply thesecond condition for equilibrium to the crane boom and derivethe resulting equation for...
a clothes washer starts from rest and spins up with an angular accceleration of 10/rad/s^2. Determine the angle through which the washer has moved afer 6 seconds.
