Three point charges lie along a straight line as shown in the figure below, where q1 = 3.51 μC, q2 = 8.03 μC, and q3 = - 8.72 μC. The separation distances are d1 = 7.28 cm and d2 = 2.34 cm. Calculate the magnitude of the net electric force on q1.

The frequency of the fundamental of the guitar string is 320 hz. at what speed v do waves move along that string?

Two conductors, a and b, are each in the shape of a tetrahedron. but of different sizes. they are charged in the following manner: 1. tetrahedron a is charged from an electrostatic generator to charge q. 2. tetrahedron a is briefly touched to tetrahedron b. 3. steps 1 and 2 are repeated until the charge on tetrahedron b reaches a maximum value. if the charge on tetrahedron b was q/4 after the first time it touched tetrahedron a. what is the final charge qbmax on tetrahedron b?

Which of these statements best explains how the hydrosphere interacts with the atmosphere to affect global climate? mountains block rain clouds and cause changes in global rainfall and evaporation. humans burn fossil fuels to produce greenhouse gases which cause global warming. humans cut down trees which affects the amount of oxygen in different parts of the globe. greenhouse gases, like carbon dioxide, dissolve in oceans and prevent global warming.
