Acylinder of gas is compressed by a piston from an initial volume of 125 liters to a final volume of 90 liters. the compression occurs at constant pressure, and the work done on the gas by the piston is 104 joules. what is the gas pressure during the compression? (1 liter = 10-3 meters3)a. 4 × 102 pascalsb. 3 × 105 pascalsc. 1 × 105 pascalsd. 3 × 104 pascalse. 3 × 10-1 pascals

explanation:

v=uf/(u-f)

= 5.-10/(5+10) convex lens has negative focal length

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.
