The image shows a ship using sonar to locate a school of fish. Which data are used to determine the distance of the ship from the fish?

A. The amount of time it takes the sound waves to travel to the fish and back to the boat​

B. The number of sound waves the ship emits

C. The amount of time it takes the sound waves to travel from the boat to the fish

D. The number of sound waves that bounce off the fish

Answers

Answer:

A

Explanation:

The distance of the object that reflected the sound wave can be calculated by knowing the speed of sound in water and the time interval between transmission and reception of ultrasound.20 Mar 2017

explain why the rocket can move at constant speed in outer space.

Answers

Answer:

When the rocket's engines are fired up, the force of gravity is disturbed, and the rocket takes off in the air. Later, as the rocket's fuel runs out, it slows down, comes to a halt, and eventually plummets to Earth's surface. Forces can affect objects in space as well. Spaceships are constantly in motion while traversing the solar system.

Explanation:

Please read!

Answer:

Explanation:

The rocket works because of the law of conservation of linear momentum. The law of conservation of linear momentum is very important in physics. Momentum is defined as the mass of an object times its velocity.

are exorcisms real and if so does that mean demons are real ???

Answers

Yes They are both real
i would believe so, yes. I mean something would have to posses someone for an exorcism right? And I highly doubt that an angel would do such terrible things to someone. So it would have to be a demon. But if demons or angels aren’t real then the people who got possessed would have to be really really good actors.

Which of the following correctly relates the porosity, permeability and production of a well in an aquifer?

Decreasing porosity and increasing permeability lead to increased production in an aquifer.
Decreasing porosity and decreasing permeability lead to increased production in an aquifer.

100 points

Answers

Answer:

Increasing porosity and increasing permeability lead to increased production in an aquifer.

Explanation:

An aquifer is a body of rock / sediment that holds groundwater.

Porosity affects the amount of water a particular rock type can hold and depends on a couple of different factors such as how water circulates within the soil or ground.

The ability of the ground water to pass through the pore spaces in the rock is described as the rock's permeability.

Therefore, Increasing porosity and permeability will lead to increased production in an aquifer.

Answer:
Increasing porosity and increasing permeability lead to increased production in an aquifer.

Why are Sea Otters considered a keystone species?

Answers

Answer:

Sea otters are considered a "keystone species" because they can exert top-down pressure via predation on sea urchins, which are grazers upon kelp.

Explanation:

As urchin density decreases from sea otter predation, so does the grazing pressure on kelp and as a result kelp forests flourish in the presence of sea otters.

True or False
If two unbalanced forces act on an object in opposite directions, the object will move in the direction that the stronger force is acting.

Answers

Answer:

true

Explanation:

If two unbalanced forces act on an object in opposite directions, the object will move in the direction that the stronger force is acting. If two forces act in the same direction on an object, the forces add together and the object experiences a greater force in that direction

True
An object in the opposite direction will act on the strongest force

Explain how water is controlled to generate electrical energy in hydro-electric dams. and show a diagram is help explain the answer.

Answers

Here is how I would I explain it. Water is channeled through tunnels in the dam. The energy of water flowing through the dam’s tunnels cause turbines to turn. The turbines make generators move. Generators are machines that produce electricity. Engineers control the amount of water let through the dam. The process used to control this flow of water is called the intake system.

Hope this helps can’t do the diagram part.
Near the bottom of the dam wall there is the water intake. Gravity causes it to fall through the penstock inside the dam. At the end of the penstock there is a turbine propellor, which is turned by the moving water. The shaft from the turbine goes up into the generator, which produces the power.Jun 6, 2018
