00 A particle of mass 0.34 kg moving on a frictionless horizontal air track
at 1.2 m/s, collides elastically with a second particle lying at rest. After
the collision, the first particle continues in its original direction at 0.66
m/s. What is the mass of the second particle?

Why is rain likely when warm, moisture-laden air meets cold air? a) the lighter warm air will rise and cool down, causing condensation and rain. b) the cold air moves faster and pushes the warm air away, causing condensation and rain. c) the moisture in the warm air condenses on contact with the cold air, causing rain to fall. d) the cold air mixes with the warm air, reducing its temperature causing moisture to condense.

Identify the correct relation showing that the radius r of the orbit of a moon of a given planet can be determined from the radius r of the planet, the acceleration of gravity at the surface of the planet, and the time τ required by the moon to complete one full revolution about the planet. determine the acceleration of gravity at the surface of the planet jupiter knowing that r = 71 492 km and that t= 3.551 days and r= 670.9 × 10^3 km for its moon europa.

Acalorimeter uses the principle that thermal energy flows from hotter material to colder material until both reach the same
