Moving water can be used to produce electricity because...
Kinetic energy can be converted into potential energy, but not vice versa.
Energy cannot be converted into other forms of energy.
Most forms of energy can be converted into other forms.
Potential energy can be converted into kinetic energy, but not vice versa.
please help me
the formula is E = P x t
The battery doesn't 'use' power. The battery produces the power that all the other electrical devices use.
If the starter motor is using 2,520 watts, then the battery is producing energy at the rate of 2,520 watts. That means 2,520 Joules of energy every second.
Thanks for giving us the formula.
E = P x t
Energy = Power x Time
Energy = (2,520 watts) x (1 second)
Energy = 2,520 Joules

As a parachutist falls with his parachute open, the downward force from the gravitational interaction is the same strength as the upward force of the drag interaction.
b. How would you describe the Forces? Explain whether or not the parachutist is accelerating.
no links pls pls plssssss :''(
Answer:
the forces are equal and the parachutist is not accelerating.
Explanation:
since the downward and upward forces are the same, the parachutist will not move up or down, so they are not accelerating.

Answer:
straight line = constant speed, downward slope = returning to start, horizontal line = not changing position = not, car covering less distance over time, so the answer is 3 the one your chose because it shows that the car is stopped.
Explanation:
Choose the correct option.
If we hit a range, it will vibrate back and forth. The range pushes / pulls the air molecules next to it, causing them to move back and forth / straight, with the same frequency. These molecules push the layer of molecules down / near, so they also start to vibrate. In this way, the oscillation is followed by one molecule next to it.
Answer:
These molecules push the layer of molecules down / near, so they also start to vibrate. In this way, the oscillation is followed by one molecule next to it.

Team Kyoto and Team Copenhagen are engaged in a fierce game of Tug of War. Team Kyoto pulls to the left with a force of 5000N and Team Copenhagen pulls to the right with a force of 5000N. Explain what net force will be and in which way (if any) the rope will accelerate.
helpppp due in 20 mins no links pweysss
Answer:
net force will be 0N and the rope will not accelerate.
Explanation:
to calculate net force, you need to find the difference between the two forces, which would be 5000N - 5000N = 0N
since there is no net force, there is no movement of the rope.

Imagine that you are an auto designer. Your job is to design brakes for different automobiles. Write a four-sentence plan that explains what you need to consider about momentum when designing brakes for a heavy truck, a light truck, a small car, and a van.
Answer:
I won't write your sentences, but I'll give you some help on them.
Explanation:
For a heavy truck, I would use heavy brakes that have much more friction. That way they would be able to stop the trucks momentum.
A lighter truck I would use lighter brakes with less friction. If I had heavy ones and I need to slam on the brakes, they might damage my lighter truck.
A small car would need lighter and smaller brakes than either of the trucks, and I think that you use different brakes for cars and trucks. (not 100% sure)
In a van, I would use a size and weight in between the truck and car sizes and weight. Depending on the van size however, I might use the same ones.
Hope this helps!
Which feature of the ocean floor is observed more than any other feature?
Which ocean floor feature is responsible for creating the largest mountain ranges in the world?
Which two ocean floor features are found most closely to the ocean shore?
Which ocean floor feature is responsible for creating new land? Which is responsible for destroying land?
Answer:
In fact, the tallest mountains and deepest canyons are found on the ocean floor; far taller and deeper than any landforms found on the continents.
Rising up from the abyssal plain, you would encounter the mid-ocean ridge, an underwater mountain range, over 40,000 miles long, rising to an average depth of 8,000 feet. Tracing their way around the global ocean, this system of underwater volcanoes forms the longest mountain range on Earth.
Underwater landforms · Continental shelf Abyssal plains Mid-ocean ridge Ocean trenches Plate tectonics and the ocean floor Hydrography.
Seafloor spreading occurs at divergent plate boundaries. As tectonic plates slowly move away from each other, heat from the mantle's convection currents makes the crust more plastic and less dense.
At the deep-sea trenches, two plates converge, with one plate sliding down under the other into the mantle where it is melted. Thus, for each segment of new ocean floor created at the ridges, an equal amount of old oceanic crust is destroyed at the trenches, or so-called subduction zones.

Could it be possible to run at the speed of sound with some future tool
Maybe in the future but now no. The fastest a human could run, according to most studies is about 36–40mph, and sound in dry air travels at about 760+ mph. That's considerably faster, almost 20 times actually. The reason why we couldn't ever run anywhere close to 760mph is because human muscles can't conract that fast.
Answer:
Scientists have discovered the fastest possible speed of sound. ... the absolute speed limit at which a wave can travel which is the speed of light

If the tractor moves and has more power than the elephant, then the elephant and the boy moves. I hope this helps you, have a great day!
What type of energy conversion happens when you draw a picture on the floor?
a. Chemical to thermal to electrical. b. Thermal to mechanical to chemical.
c. Mechanical to chemical to thermal. d. Chemical to mechanical to thermal.
Answer:
B.
Explanation:
Ur welcome
When a picture is drawn on the floor, chemical energy is converted to mechanical energy and then to thermal energy.
What is thermal energy?Thermal energy is defined as a type of energy which is contained inside a system and is responsible for temperature rise.Heat is a type of thermal energy.It is concerned with the first law of thermodynamics.
Thermal energy arises as a result of friction and drag.It includes the internal energy or enthalpy of a body of matter and radiation.It is related to internal energy and heat .It arises when a substance has molecules or atoms which are vibrating faster.
These vibrating molecules and atoms collide with each other and as a result of which heat is generated in a substance , more the collision of particles , higher is the thermal energy.

Is the gravitational force between the two objects attractive, repelling, or both? Explain how you know.
Answer:
Explanation: Gravity is always pulling any object to the center of the earth and we know that because if it not for gravity/gravitational pull we would be floating out of orbit and would not be to touch the ground.

The diagram below shows four forces acting on an object. The forces are labeled A, B, C, and D:
Describe the direction of the object’s motion based on the forces shown in the diagram. Be sure to include vertical (up and down) and horizontal (side to side) movement in your answer
no mfkn links pls pls plssssss
Answer:
the object will move in the direction of a and d, with a force of 10N acting on it.
Explanation:
the forces b and c cancel each other out because they are equal, but pushing the object in opposite directions. thus, 5N - 5N = 0N and the object does not move.
however, the forces a and d are moving in the same direction. 5N + 5N = 10N, which means that the object will move in the direction of both a and d with a combined force of 10N acting on it.

How does density play a part in convection currents? Explain.
(I NEED THE ANSWER ASAP)
Answer:
Convection is heat transfer due to a density differential within a fluid
Example:
The current begins when the air over the hot sand is heated and begins to rise because of its lowered density. Air from above the ocean is colder and more dense. This cooler air takes the place of the rising hot air from over the sand
