How to self-study physics and electrical engineering without going to college? You can buy used textbooks and study it and when you're stucked, can you go to the nearest college and get tutored? For...

A. What is the period of rotation? B. What is the velocity if the object is 14 cm from the center of rotation? C. What is the centripetal force on a 35 g mass spinning 14 cm from the center...

1. Make two free body diagrams for a falling coffee filter: one at the instant when it is released and the other after it has reached terminal velocity. Your diagrams should include numerical values...

1. Give three factors that affect the amount of air resistance an object experiences, and describe how each factor influences air resistance (will the air resistance go up, or go down if that variable...

Compute the normal force on the block. M=47.3 kg and theta=31.0 degrees

i have to explain this on a paper and i dont know how to start

13. A water droplet of radius 0.018mm remains stationary in air. If the downward electric field in 150N/C, how many excess electrons must the droplet have?

An electric dipole consists of a pint charge -q at the point (0,a) and a point charge q at the pint(0,-a). Find the electric field at the point (x,0).

. The photo shows physics teacher Marshall Ellenstein walking barefoot on broken glass bottles in his class. What physics concept is Marshall demonstrating, and why is...

In a sporting goods store you see what appears to be two identical life preservers of the same size. One is filled with Styrofoam and the other one is filled with lead pellets. If you...

. Show that the water pressure at the bottom of the 50-m-high water tower in Figure 5.3 is 490,000 N/m2, or is approximately 500 kPa

58. Which has the higher specific heat capacity: an object that cools quickly or an object of the same mass that cools more slowly?

Please help me with this. It looks long, but it really is not. A physics student wants to determine the relationship between the radius of a charged conducting sphere and the magnitude of...

Please help! I just do not even know what I'm doing, and currently waiting for tutors to respond to work with me one on one. An unknown fluid could be determined from ρfl=(T-T'')/(T-T')...

A lab experiment was performed to find the centripetal force on a rotating body which measured mass(m), frequency(n), and radius(r). It was found that Fc=4Π2n2mr. How do I write an expression...
