Problem 2: Mystery bubble A mystery fluid is blown into a bubble at sea level. The gauge pressure of the gas in the center the bubble is measured to be 200 Pa when its radius is 6.3 cm. A. What is the surface tension of the mystery fluid

Why is there friction between objects

The extremely high temperatures needed to trigger nuclear fusion are proposed to be generated by laser irradiating a spherical pellet of deuterium and tritium fuel of diameter 1.8 mm. (a) determine the maximum fuel temperature that can be achieved by irradiating the pellet with 200 lasers, each producing a power of 550 w. the pellet has an absorptivity 0.3 and emissivity 0.8.

Describe the path of a ray that approaches a mirror parallel to the principal axis.
