A small object carrying a charge of -5.50 nC is acted upon by a downward force of 24.0 nN when placed at a certain point in an electric field.
What would be the magnitude and direction of the force acting on a proton placed at this same point in the electric field?
Magnitude & Direction of the...
Thanks. I just figured that out after 5 mins of Googling. My professor hasn't gone over that yet. I guess that is what Friday's lecture is about...since this HW isn't due unti Sunday. Thanks again!
[SOLVED] Simple Harmonic Motion - Period (T)
1. A pendulum oscillates with a period T.
If both the mass of the bob and the length of the pendulum are doubled, the new period will be _____.
2. T = 2(pi) x rad (k/m)
3. Since L is not a part of the equation, it shouldn't affect...
[SOLVED] Torque Part 2
Two people are carrying a uniform wooden board that is 3.40 meters long and weighs 145 N.
If one person applies an upward force equal to 60.0 N at one end, at what point does the other person lift?
d = _____ meters from the end where the first person lifts...
A square metal plate 0.180 meters on each side is pivoted about an axis through point O at its center and perpendicular to the plate.
Calculate the net torque about this axis due to the three forces shown in the figure if the magnitudes of the forces are F1 = 18.0 N F2 = 27.0 N and F3 = 14.0...
Yeh, I got that about 5 mins after I posted this (and the forum for down for me, I couldn't access it). Thanks for your help, though. It's much appreciated. :)
[SOLVED] Work-Energy Principle
1. The problem...
On an essentially frictionless horizontal ice-skating rink, a skater moving at 3.00 m/s encounters a rough patch that reduces her speed by 45.0 % to a friction force that is 25.0 % of her weight.
Use the work-energy principle to find the length...
