A fisherman 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

Answer:

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

A sound wave of wavelength 0.682 m and velocity 325 m/s is produced for 0.500 s. what is the frequency
Naya [18.7K]
Recall that given the velocity and wavelength, frequency can be computed as

frequency =  \frac{speed}{wavelength}
Substituting the given values, we have
frequency =  \frac{325 m/s}{0.682 m}  \\ frequency = 477 Hz

Answer: 477 Hz

One way to force air into an unconscious person's lungs is to squeeze on a balloon appropriately connected to the subject. What
frozen [14]

Answer:

The force that you must exert on the balloon is 1.96 N

Explanation:

Given;

height of water, h = 4.00 cm = 4 x 10⁻² m

effective area, A = 50.0 cm² = 50 x 10⁻⁴ m²

density of water, ρ = 1 x 10³ kg/m³

Gauge pressure of the balloon is calculated as;

P = ρgh

where;

ρ is density of water

g is acceleration due to gravity

h is height of water

P = 1 x 10³ x 9.8 x 4 x 10⁻²

P = 392 N/m²

The force exerted on the balloon is calculated as;

F = PA

where;

P is pressure of the balloon

A is the effective area

F = 392 x 50 x 10⁻⁴

F = 1.96 N

Therefore, the force that you must exert on the balloon is 1.96 N

It takes 6 seconds for a stone to fall to the bottom of a mine shaft. how deep is the shaft
Margaret [11]
You need the kinematic equation for distance as a function of acceleration:

d = [v(initial) *t] + 0.5a*t^{2}

where a = gravitational acceleration 9.8m/s^{2}
v(initial) = starting velocity
t = time of fall

if the stone started at rest then v(initial) = 0 making the equation simply 0.5a * t^{2}

Let me know if you still need further help :)

How do streams change as they flow from mountains down to plains? Plz help URGENT I need it today
lisov135 [29]
They start as one stream, then get curvier, then empy into a delta. A delta is a ton of streams of water. It is one, then empties out into a ton of streams.
