how would you solve this problem? A charge q1 = 3.40 nC is placed at the origin. Three identical charges, q2, q3 q4, are placed at the positions (0.100 m, 0 m), (0 m, 0.100 m), and (0.100 m, 0.100 m). What is the potential energy of this configuration of charges? should you do answer =...

is angular momentum conserved and if so how would that apply

A large turntable rotates about a fixed vertical axis, making one revolution every 5.00 s. The moment of inertia of the turntable about its axis is 1.10e+03 kgm2. A man of mass 85.0 kg initially standing at the center of the turntable runs out along a radius. What is the angular speed of the...

A 1.00 kg block is compressed a distance of x = 0.130 m against a vertical massless spring with spring constant 280 N/m. The block is released from rest. How far above the spring's equilibrium point does the block travel? I used conservation of energy and got 0.5kx^2 + 0.5mv^2 + mgh =...

thanks!

How do you find the maximum voltage that can be placed across the capacitor? It is a parallel plate strontium titanate filled capacitor, that has plates of area 0.78 m^2 and a separation of 0.070 mm. It also has a dielectric constant of 310 and a dielectric strength of 8.0 kV/mm. I already...

A point charge q1 = 9.00 nC is located at the origin, and a second point charge q2 = -3.00 nC is on the x-axis at x = 1.00 m. What is the total electric flux due to these two point charges through a spherical Gaussian surface centered at the origin and with radius (a) 0.500 m? E =...

yeah but what is the spring constant, K. I sort of need that to solve the problem.

The scale of a spring balance reading from zero to 180 N is 7.00 cm long. A fish suspended from the balance is observed to oscillate vertically at 2.50 Hz. What is the mass of the fish? Neglect the mass of the spring. ________ kg Attempt k =(180-0)/(7-0) = 25.714 N/m frequency =...

thanks for all your help! i just forgot to divide by two

the answer i put for the first part was 0.493 and it was right. But for the secound part i got 0.493 as well is that right? i am not sure and really need an answer fast.

thanks

so would it be like this then? m*v = f*t (70)(20) = F * (0.1) 1400= 0.1F F=14000

So i read up on this and did this. It was marked wrong can someone help me figure out why? m*v = f*t (1900 + 70)(20) = F * (0.1) 39400= 0.1F F=394000

Help urgently need someone to help me check pulley problem Two masses are connected over a small pulley using a light string. The mass on the left is 1.00 kg and the mass on the right is 6.50 kg. The mass on the right is a distance 2.00 m above the ground. The system is released from rest as...
