Two pistons are in an enclosed volume with fluid in between them, such thatmovement in one piston affects the location of the other piston, as shown inthe image below. If an explosion occurs in the piston on the left such that itmoves 1 m, what is the distance that the piston on the right will move(assuming that friction can be neglected)? (Recall that work on an object isequal to the force on the object times the distance it is moved, and that workis conserved.)Cross-sectional area - 25 mmCross-sectional area = 0,5 mA. 2 mB. 0.5 mC. 1 mD. 0.25 m

The magnetic field perpendicular to a single wire loop of diameter 10.0 cm decreases from 0.50 T to zero. The wire is made of copper and has a diameter of 2.0 mm and length 1.0 cm. How much charge moves through the wire while the field is changing?I know how to do the calculations, but can someone please explain what is the 10cm diameter and 2mm diameter? Why is there one wire and two diameters? I understand this problem mathematically but not conceptually.

A laser beam is used to levitate a metal disk against the force of earth's gravity.(a) derive an equation giving the required intensity of light, i, in terms of the mass m of the disk, the gravitational acceleration g, the speed of light c, and the cross-sectional area of the disk a. assume the disk is perfectly reflecting and the beam is directed perpendicular to the disk. (do not substitute numerical values; use variables only.)i=(b) if the disk has mass 3.89 g and radius 2.40 cm, find the necessary light intensity.(c) give two reasons why using light pressure as propulsion near earth's surface is impractical.
