With the temperature held constant, the pressure of a gas in a cylinder with a movable piston is increased from 18 kPa to 40 kPa. The initial volume of the gas in the cylinder is 0.75 m^3. What is the final volume of the gas after the pressure is increased?

Awave is produced in a rope. the wave has a speed of 33 m/s and a frequency of 22 hz.

Awater balloon launcher uses an elastic band with a spring constant of 115 n/m to use thee launcher you stretch thee band back with a balloon n it the water balloons have a mass of 1.3 kg a) if you stretch the band by 0.8 m, what elastic force will the band exert? b) with the band stretched 0.8 m, how much elastic potential energy is stored in the spring? c) if you release the band, it pushes forward. what is the kinetic energy of the balloon when it reaches the natural length of the band? d) what is the speed of the balloon when it reaches the natural length of the band?

Emagnitude of the electrical force acting between a +2.4 ×  10–8  c charge and a +1.8 ×  10–6  c charge that are separated by 0.008 m is    n, rounded to the tenths place.
