You have a 200 ω resistor, a 0.400 h inductor, a 6.00 μf capacitor and a voltage source that has a voltage amplitude of 30.0 v and an angular frequency of 250 rad/s. the resistor, inductor, capacitor, and voltage source are connected to form an l-r-c series circuit. the current is given by i=icos(ωt), so v=vcos (ωt φ). what is v at t = 20ms? what is vr at t = 20ms? what is vc at t = 20ms? what is vl at t = 20ms? what is v at t = 40ms? what is vr at t = 40ms? what is vc at t = 40ms? what is vl at t = 40ms?

the box does not move because you need to use a force greater than 300 n. you are only using 50 n. it needs to at least be 301 n for the box to move because then it is an unbalanced force and it will move the way that the greater force is pushing it. if you use only 300 n it will be a balanced force and will not move because the force you are exerting on the   box is the same as its force.

hope this !

im sorry if i went too in depth, i am going to include a link to a video on khan academy that will explain this.   hope that you like the video and that it explains more in detail to you.

that is the link.

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

3÷1000kg = 0.003

1.5÷100m = 0.15

0.003/0.15 = 0.02kg
