Two loudspeakers in a plane, 5.0 m apart, are playing the same frequency. if you stand 11.0 m in front of the plane of the speakers, centered between them, you hear a sound of maximum intensity. as you walk parallel to the plane of the speakers, staying 11.0 m in front of them, you first hear a minimum of sound intensity when you are directly in front of one of the speakers. part a)what is the frequency of the sound? assume a sound speed of 340 m/s. i got 120.02 hz. this is right, i checked. part b)if you stay 12.0 m directly in front of one of the speakers, for what other frequencies between 100 hz and 700 hz is there a minimum sound intensity at this point?

It is may 5 and you are somewhere in the northern hemisphere. if you determine that the noon sun is 51 degrees above your southern horizon, what is the latitude of your location

There is a theory that indicates that dinosaurs became extinct when about 65 million years ago, a large asteroid hit the earth surface. dust caused by this collision blocked the sunlight reaching the earth's surface and many forms of life became extinct due to the cold. fearing this threat, how large the radius of an asteroid should you be looking for if the dangerous asteroid size is approximately the same as the one that killed the dinosaurs? available data suggests that about 18% of that asteroid's mass ended up as a dust spread evenly over earth after eventually settling out of the upper atmosphere. about 0.0180 g/cm^2 of dust, which is chemically different than the earth's rock, covered the earth's surface. typical asteroids have a density of about 1.9 g/cm^3. now that we know the size of the asteroid, how much energy was released during impact, assuming all of it was just the kinetic energy of the asteroid right before the impact?

The amount of potential energy possessed by an elevated object is equal to what?
