An infinitely long thin wire carrying linear charge density λ is brought close to a semi-infinite neutral conductor which covers space for x < 0. The wire is a distance d away and is oriented so that it is parallel to the y − axis. Calculate the force per length ` that acts on the wire.

Agymnast dismounts off the uneven bars in a tuck position with a radius of 0.3m (assume she is a solid sphere) and an angular velocity of 2rev/s. during the dismount she stretches out into the straight position, with a length of 1.5m, (assume she is a uniform rod through the center) for her landing. the gymnast has a mass of 50kg. what is her angular velocity in the straight position?

What is relative velocity? in which condition is relative velocity known by adding the velocity of the first body and that of the second body

You are about to open a container of soy milk but notice that there are instructions to “shake well before serving.” the soy milk is most likely a
