3 points The following diagram shows molecules in a gas at different
times. Each diagram is the same mass of air, just at different
volumes and temperatures. Assume that the pressure of the gas
has remained the same in each case. Rate the gases according to
volume. The gas that has the largest volume should be rated a 3.
The gas that has the smallest volume should be rated a 1. *

The position of a dragonfly that is flying parallel to the ground is given as a function of time by r⃗ =[2.90m+(0.0900m/s2)t2]i^− (0.0150m/s3)t3j^. a: at what value of t does the velocity vector of the insect make an angle of 34.0 degree clockwise from the x-axis? b: at the time calculated in part (a), what is the magnitude of the acceleration vector of the insect? c : at the time calculated in part (a), what is the direction of the acceleration vector of the insect?

Aquantity of gas has a volume of 1.5 m3 and an absolute pressure of 95 kpa. when the gas is compressed to a volume of 0.5 m3, what is the new absolute pressure of the gas? (assume that there’s no change in temperature.)
