yeah I can see it now..Thanks a lot !

Value of Zs should be 20 + jωL which comes up to be 20+10j so the impedance of ZL must be 20 -10j right? Is it correct to assume that this must be equal to the parallel combination, eg. ZcZR/Zc+Zr? I am a bit confused!

Homework Statement In the circuit attached the load impedance ZL comprises a resistor in parallel with a capacitor. Determine the value of the resistor and the capacitor to ensure that the maximum power is received by the load impedance. The Attempt at a Solution So,if components in ZL...

Ok I see now.. Thank you for your quick reply.

Homework Statement are included in the attached image. I've solved the first two parts, my question is about part c. It makes more sense for me to think that the tube has gained some velocity after the collisions and moves to one direction. Probably on the left because the velocity gained from...

Ok I've found it! Angle is in radians,my calculator was set up in degrees. Thank you both !

I have attached an image of extaclty what i did. I hope am not doing any stupid mistake:p

So, for range is what I've found in a) which is 31800m and correct according to the answers. t=106 s and θ=7.7x10^-3

Here's what I did..I found the angular velocity of Earth by doing ω=2π/86400 and then I found the angle by θ=ωt. Then using a triangle I did tanθ= distance target moved/range. But the result I'm getting is way out of that i should get. I find 4,27m and the answer should be 245m..I can't figure...

Don't I need the radius of earth?

Hello guys..I am new in the forum,glad to find you and I think a great work is done here.So my problem is that I have a question on projectiles,I've solved easily the first part but the second part doesn't make any sense to me.I don't even know what it means.Note that english is not my first...
