Here's the problem:
Two speaks side by side are separated by 1 meter. If the sound intensity is found to reach its first maximum when someone stands 1.0 meter directly in front of one of the speakers ( ie. perpendicular to the line between the speakers) what is the wavelength of the sound...
1. An electron with a speed of 3.0 x 106 m/s moves into a uniform electric field of 1000 N/C. The field is parallel to the electron's motion. How far does the electron travel before it is brought to rest.
I read the part of the text related to electric fields but I saw nothing that related...
Can someone please help with this problem. I'm lost!
1. A 150 kg bear walks out onto a beam as illustrated in Fig P8.20 trying to get to a picnic
basket with mass 10kg. The beam is 6m long and has mass 40kg (you can consider its
weight to be concentrated at a point 3m from the wall.

This seems like an easy problem but without "time" i"m confused.
The best leaper is a Puma that can jump to a height of 12 feet when leaving the ground at a 45 degree angle. With what speed in SI units must the Puma leave the ground to reach this height?
I'm not sure what formula to apply...
Thanks for your help so far. I feel really dumb so please be patient with me.
Ok, I took 250/75 and got the inverse tangent of 73.3 degrees. Then I took the sin of 73.3 degrees (.9578) and divided 250 by .9578 to get vector quantity of 261.
Is this correct so far?
Yes. We are currently doing projectile motion, but of course I am having trouble. I'm a Bio major with a 3.8 index. I think I just need to be pointed in the right direction (no pun intended). I need to get the appropriate vector neurons to start firing.
Here's the problem:
While exploring a cave a student starts at the entrance and moves the following distances. She goes 75.0 m north, 250 m east, 125 m at an angle 30.0 degrees north of east, and 150 m south. Find the resultant displacement from the cave entrance.
I drew a diagram to...
