A force is anything that can push or pull on an object. Forces influence objects that are at rest or that are already in motion. Isaac Newton's three laws of motion involve inertia, mass, velocity, and momentum. Key forces include gravity, friction, and magnetism.
B nitrogen stays in order so it can't change movement
Answer:
(a) 693.12 torr
(b) 68.5 kilopascals
(c) 0.862 atmosphere
(d) 1.306 atmospheres
(e) 36.74 psi
Explanation:
(a) 0.912 atm = 0.912 atm × 760 torr/1 atm = 693.12 torr
(b) 0.685 bar = 0.685 bar × 100 kPa/1 bar = 68.5 kPa
(c) 655 mmHg = 655 mmHg × 1 atm/760 mmHg = 0.862 atm
(d) 1.323×10^5 Pa = 1.323×10^5 Pa × 1 atm/1.01325×10^5 Pa = 1.306 atm
(e) 2.50 atm = 2.50 atm × 14.696 psi/1 atm = 36.74 psi
Speed = distance/time taken
1484 = distance/3
Distance = 1484 x 3
Distance = 4452 m
