Explain what surface tension is.

A helium-filled balloon is launched when the temperature at ground level is 27.8°c and the barometer reads 752 mmhg. if the balloon's volume at launch is 9.47 * 10^{4} 4 l, what is the volume in liters at a height of 36 km, where the pressure is 73.

Consider the moment when the spring is at its maximum compression. At that moment, the kinetic energy, the gravitational potential energy, and the elastic potential energy are, respectively, a - zero, at a maximum, and at a maximum b - at a maximum,
