Afisherman notices that his boat is moving up and down periodically, owing to waves on the surface of the water. it takes 2.80 for the boat to travel from its highest point to its lowest, a total distance of 0.620 . the fisherman sees that the wave crests are spaced 6.40 apart.

how fast are the waves traveling? in m/s

what is the amplitude of each wave? in m

if the total vertical distance traveled by the boat were 0.500 , but the other data remained the same, how fast are the waves traveling ? in m/s

if the total vertical distance traveled by the boat were 0.500 , but the other data remained the same, what is the amplitude of each wave? in m

a)1.14

b)0.31

c)1.14

d)0.25

Explanation:

Assume wave travels in a harmonic motion. This means if it takes 2.8 for the boat to travel from highest to lowest point, then it'd take 2.8*2 = 5.6 for the boat to travel in 1 period (from highest point to lowest point then back to highest point again).

a)As the wave crest is 6.4 apart. Then it's speed is

v = s/t = 6.4/5.6 = 1.14

b) The amplitude would be half of the vertical distance traveled by the boat, which is

A = 0.62 / 2 = 0.31

c) As the distance between the crest and the time it takes for the boat to travel vertically is unchanged, then the wave speed would stay the same:

v = 1.14

d) The amplitude would again be half of the vertical distance

A = 0.5 / 2 = 0.25

the expression 15n + 2(3p) represents the amount isaiah spent buying gasoline and snacks, where n represents the price of each gallon of gasoline and p represents the cost of each snack that he bought. which statement is true about the amount isaiah spent?

answer: d. a cme increases the amount of energy in the solar wind

explanation:

coronal mass ejections, also called cmes, are large clouds of plasma and magnetic field that erupt from the sun. only when the cloud is aimed at earth will the cme hit earth and therefore cause impacts. high-speed solar wind streams come from areas on the sun known as coronal holes.
