Two identical loudspeakers are driven in phase by a common oscillator at 750 Hz and face each other at a distance of 1.26 m. Locate the points along the line joining the two speakers where relative minima of sound pressure amplitude would be expected. (Take the speed of sound in air to be 343 m/s. Choose one speaker as the origin and give your answers in order of increasing distance from this speaker. Enter 'none' in all unused answer boxes.)

Ahole in the ground in the shape of an inverted cone is 14 meters deep and has radius at the top of 11 meters. the cone is filled to the top with sawdust. the density of the sawdust depends upon the depth, x, following the formula ρ ( x ) = 2.5 + 1.2 e − 0.7 x kg/m3. find the total mass of sawdust in the conical hole.

Mark saxby is set to kick the field goal to win the state championship for olathe east. he is 47m away from the goalposts, and he kicks the ball at a speed of 25.0m/s at an angle of 30.0°. if the cross bar on the goalposts is 3.00m above the ground, will the ball make it over the cross bar? and if it does make it, by how much will it clear?
