What is the volume of a aluminum ball at 10 degree celsius if its volume at 160 degree celsius is 300m³
An empty rubber balloon has a mass of 0.0120 kg. The balloon is filled with helium that has a density of 0.179 kg/m3. The filled balloon has a radius of 0.500 m. (density of air is 1.29 kg/m3 and assume no air resistance). The balloon is now released, find the following:
a) The acceleration of the balloon.
b) The final velocity of the balloon after 10 s.
c) The height of the balloon after 10 s.
At normal pressure (101325 Pa) a gas has 1 ∙ 1022 molecules per unit volume. What is the average kinetic energy of its molecules?If I walk 20 miles north, then 15km east, then 10 km at 35 degree south of east, what is the magnitude of my displacement?
Jorge pushes a 10 kg box of medicine along a rough surface with 35N of force. He observes that it is only accelerating at a rate of 2 m/s2. What must the value of the force of friction be? (Assume the only two forces acting on the object are friction and Jorge).
What is positronium system.

A cup is made of an experimental material that can hold hot liquids without significantly
increasing its own temperature. The 0.80 kg cup has an initial temperature of 37 degrees C
when is submerge in 1.54 kg of water with an initial temperature of 20 degrees C. What is the
specific heat capacity if the final temperature is 27 degrees C?A cup is made of an experimental material that can hold hot liquids without significantly
