The heat in the air ballon from the flame will create moisture in the ballon and make it rise
Answer:
c. Your body is at rest but its inertia puts it in motion
Explanation:
Answer:
(a). The distance from the initial position is 6.68 km.
(b). The magnitude of their displacement is 7.05 km.
Explanation:
Given that,
Geese fly 4.0 km due west, then turn to north by 40° and fly another 3.5 km.
(a). We need to calculate the distance from the initial position
Using formula of distance

Put the value into the formula


(b). We need to calculate the magnitude of their displacement
Using formula of displacement



Hence, (a). The distance from the initial position is 6.68 km.
(b). The magnitude of their displacement is 7.05 km.
Red light would be commonly used due to the longer wavelength
