I try to think of things that calms me down. If that doesn't work, I try to think of things that makes me happy. As I once read in a book, you can never get over your anger but you can calm yourself down by forgetting about it.<span />
Answer:
λ = 28,14 m
Explanation:
To find the wavelength of the wave you use the following formula:
(1)
v: speed of the wave = 1,97 m/s
λ: wavelength
f: frequency of the wave = 0,07 Hz
You replace the values of v and f in the equation (1) and solve for λ:
hence, the wavelength of the wave is 28,14 m

➷ Speed = distance / time
Substitute in your values:
Speed = 720 / 8
Speed = 90
They traveled 90 miles per hour

Answer:
Option e
Explanation:
The Law of Universal Gravitation states that every point mass attracts every other point mass in the universe by a force pointing in a straight line between the centers-of-mass of both points, and this force is proportional to the masses of the objects and inversely proportional to their separation This attractive force always points inward, from one point to the other. The Law applies to all objects with masses, big or small. Two big objects can be considered as point-like masses, if the distance between them is very large compared to their sizes or if they are spherically symmetric. For these cases the mass of each object can be represented as a point mass located at its center-of-mass.
The same force is applied to both the balls.
