What happen as waves travel and objects in their path move?
Cerrena [4.2K]
Do you mean when objects move as a direct result of the passing wave? Waves have energy and constitute a force, just like wind. Therefore that force is able to move objects in its path.

average speed = distance covered divided by travel time. do some algebra and multiply both sides of this relation by travel time
mars1129 [50]
Based on the scenario,
The thing that the result say about distance covered is :
it tells you that the distance covered is equal to the average speed times the travel time

hope this helps

.. A 15.0-kg fish swimming at 1.10 m&gt;s suddenly gobbles up a 4.50-kg fish that is initially stationary. Ignore any drag effec
stira [4]

Answer:

(a) 0.846 m/s

(b) 2.097J

Explanation:

Parameters given:

Mass of big fish, M = 15 kg

Mass of small fish, m = 4.5 kg

Initial speed of big fish, U = 1.1 m/s

Initial speed of small fish, u = 0 m/s (it is stationary)

(a) We apply the principle of conservation of momentum:

Total initial momentum = Total final momentum

Since both fish have the same final speed, V, (the small fish is in the mouth of the big fish), we have:

MU + mu = (M + m)*V

(15 * 1.1) + (4.5 * 0) = ( 15 + 4.5) * V

16.5 = 19.5V

=> V = 16.5/19.5

V = 0.846 m/s

The speed of the large fish after the meal is 0.846 m/s.

(b) We need to find the change in Kinetic energy of the entire system to find the total mechanical energy dissipated.

Initial Kinetic energy:

KEini = (½ * M * U²) + (½ * m * u²)

KEini = (½ * 15 * 1.1²) + (½ * 4.5 * 0²)

KEini = 9.075 J

Final Kinetic Energy:

KEfin = (½ * M * V²) + (½ * m * V²)

KEfin = (½ * 15 * 0.846²) + (½ * 4.5 * 0.846²)

KEfin = 5.368 + 1.610 = 6.978 J

Change in kinetic energy will be:

KEfin - KEini = 9.075 - 6.978

ΔKE = 2.097 J

The energy dissipated in eating the meal is 2.097 J

A weight lifter bench‑presses a 160.0 kg 160.0 kg barbell from his chest to a height equal the length of his arms, 0.800 m . 0.8
Vaselesa [24]

Answer:

A. 1254.4 J

B. 1254.4 J

C. 43904 calories

Explanation:

Parameters given:

Mass of barbell, m = 160 kg

Length of arm, d = 0.8

A. Work done by weight lifter in lifting the barbell is:

W = F * d

Where F is force

F = m * g

=> W = m * g * d

W = 160 * 9.8 *0.8

W = 1254.4 J

B. Potential energy is given as:

PE = m * g * h

Where h is height (in this case, D)

=> PE = m * g * d

PE = 160 * 9.8 * 0.8

PE = 1254.4 J

C. The number of calories the weight lifter uses after lifting the barbell 35 times is equal to 35 times the potential energy, since a calorie is the measure of the amount of potential energy a piece of food contains:

35 * 1254.4 = 43904 calories.
