What is the rms speed of helium atoms when the temperature of the helium gas is 206.0 k? (possibly useful constants: the atomic mass of helium is 4.00 amu, the atomic mass unit is: 1 amu = 1.66x10-27 kg, boltzmann's constant is: kg = 1.38x1023 j/k.) submit answertries 0/20 what would be the rms speed, if the temperature of the helium gas was doubled?

Juan created a chart to him study for a test. which headings best complete the chart? x: transparent objects y: opaque objects x: opaque objects y: transparent objects x: high frequency waves y: low frequency waves x: low frequency waves y: high frequency waves

It's a snowy day and you're pulling a friend along a level road on a sled. you've both been taking physics, so she asks what you think the coefficient of friction between the sled and the snow is. you've been walking at a steady 1.5m/s, and the rope pulls up on the sled at a 32 ∘ angle. you estimate that the mass of the sled, with your friend on it, is 65 kg and that you're pulling with a force of 80 n .
