You have three identical charged spheres, each with a charge of 2.80 µC. You have arranged them so they are each at the corners of a square that measures 4m on a side. Find the magnitude of the electric field at the "empty" corner. (The corner with no charged s...
Directly below on the floor is a stationary 428-Hz source of sound. The microphone vibrates up and down in simple harmonic motion with a period of 2.3 s. The difference between the maximum and minimum sound frequencies detected by the microphone is 2.2 Hz. Ignoring any reflect...

Plain θ miles
An airplane flies at an altitude of 5mies toward a point directly over an observer. The speed of the plain is 600 miles per hour. Find the rate at which the angle of elevation thetha is changing when the angle is 75 degrees. Please help with this question.
Geometry Question (multiple choice)!
The isosceles trapezoid is part of an isosceles triangle with a 34° vertex angle. What is the measure of an acute base angle of the trapezoid? Of an obtuse angle? 73°; 107° 34°; 146° 73°; 146° 34°; 107° Thank you =) :) ;)

1) With reference to electrochemical corrosion, explain the following phenomena: i) Anodic Polarization ii) Cathodic Polarization 2) What are two degradation mechanisms that are the responsible for the loss in molecular weight of polymeric materials?
yep and then you do the sqrt( -29.9^2 +98.2^2) to get the velocity
