A block of mass 12.0kg slides from rest downa frictionless 35.0 degree incline and is stopped by a strongspring with k=3.00x10 the 4th N/m. The block slides 3.00m from thepoint where it comes to rest against the spring. When the blockcomes to rest, how far has the spring been compressed.
assume the current in the coaxial cable, see the figure , is not uniformly distributed, but instead the current density varies linearly with distance from the center: for the inner conductor and for the outer conductor. Each conductor still carrie..
observations of a certain galaxy show that stars at a distance of 16 pc from the center of the galaxy orbit a central
