What happens in
this circuit after the
current leaves the
battery?
A. It goes through all three lights and back to the battery.
B. It goes through all three lights and stops.
C. It goes through the wire and stops.
Answer:
The current is basically the intensity of the electrons over a period of time, in a way.
So, if electrons are leaving the battery to carry charge, they must come back to the battery eventually :).
Your answer is A, it goes back to the battery

The sum of the kinetic and potential energies of a system of objects is conserved only when no external force acts on the objects.
Conservation of mechanical energyThe principle of conservation of mechanical energy states that the total mechanical energy of an isolated system (absence of external force) is always constant.
M.A = P.E + K.E

5.whats beyond the observable universe?
6.why cant we use gravity of an object in space and create an artificial atmosphere. how could that be done?
If you have more questions you can tell me in comments.
Answer:
Explanation:
I'm assuming these are personal questions? Because a few of your questions are incorrect. I'll do my best to explain the ones I do know.
1.) Nobody actually knows what would happen if you travel faster than light. Einstein showed this was impossible due to it requiring an "infinite" amount of energy. My personal belief is that time itself stops existing. Your guess is as good as mine, nobody really knows.
2.) Most objects in the universe are round mostly because of gravity and density. All objects in the universe strive for minimum energy states. A sphere has a minimum gravitational potential than other geometry.
3.) Again, this is another one where nobody knows "why." On the macroscopic, there is classical mechanics. Then once you go into the microscopic world, you enter the realm of quantum mechanics. It's not that the "laws" are different. There is still conservation of momentum and such. Its just that they're expressed differently.
4.) The explanation for this is most likely due to light being composed of particles, photons. Sound cant travel if there is no medium, because sound is purely a wave. There is no such thing as a sound particle, at least not a physical one. You can think of light as traveling photons carrying energy. That's the particle interpretation of light.
Space missions do not use the Earth's momentum to catapult things in space. Each mass in the universe creates a corresponding gravitational field. So, planets create gravitational fields. The current theory of gravity is Einstein's theory of General Relativity, which states that energy and momentum curve spacetime. Special relativity proved the energy/mass equivalence. General relativity predicts that spacetime will curve around large masses. You can think of planets bending spacetime like a bowling ball in the center of a trampoline. This process in reality is 3-D and not 2-D like the trampoline analogy. But, the entire process of "catapulting" is using these gravitational "wells" of spacetime to minimize fuel and travel time.
5.) We don't know what beyond the observable universe. From the Big Bang, the universe only existed for about 13 billion years. So, light only traveled for 13 billion years long. We cant see passed the observable universe if the light hasn't even reached us yet. The reason the size of the observable universe is larger than 13 billion light years, is because we predict the universe is expanding faster than the speed of light. Special relativity demands that mass cannot go faster than the light, but it never restricted spacetime itself.
6.) Planets use gravity to keep their atmosphere. We could theoretically place a massive object on a planet and increase the gravitational field. But that is really impractical. We can't "create" gravity because we dont know if gravity is a particle. We only think of it at the moment as a non-physical wave, a ripple in spacetime. I have personal thought experiments in how we could terraform a planet, and create atmospheres. But that goes into electromagnetism, and not gravity.

A 2.0 kg melon is balanced on a circus performer's head. An archer shoots a 50.0 g arrow at the melon with a speed of 30 m/s. The arrow passes through the melon and emerges with a speed of 18 m/s. Find the speed of the melon as it flies off the performer's head.
The speed of the melon as it flies off the performer's head is 0.3 m/s
Law of conservation of momentum?The law of conservation of momentum states that for a system of colliding bodies, the total momentum before the collision is equal to the total momentum after the collision, provided there is no net external force acting on the bodies.
To find the speed of the melon, we use the formula from the law of conservation of momentum.
Formula:
mu+m'u' = mv+m'v'............ EquationWhere:
m = mass of the melonu = initial velocity of the melonm' = mass of the arrowu' = initial velocity of the arrowv = final velocity of the melonv' = final velocity of the arrow.From the question,
Given:
m = 2 kgm' = 50 g = 0.05 kgu = 0 m/s (at rest)u' = 30 m/sv' = 18 m/s.Substitute these values into equation 1
(2×0)+(0.05×30) = (0.05×18)+(2×v)0+1.5 = 0.9+2v2v = 1.5-0.92v = 0.6v = 0.3 m/s.Hence, The speed of the melon as it flies off the performer's head is 0.3 m/s.

It is best to say that efficient plumbing reduces water pollution by using less water. Option a is correct.
What is plumbing?Plumbing is a water conveyance system that transports water for a variety of uses. It transports water from one location to another via pipes, valves, and tubes.
It has the ability to transport water from a large reservoir to several areas. It is required for agricultural irrigation, domestic cleanliness, and the provision of potable drinking water.
Filters are often used in plumbing systems to remove pollutants from the water. An effective plumbing system lowers water pollution by using less water
Since it allows for adequate flow of water for usage and can automatically close or turn up as needed, preventing the loss of clean water and therefore preventing pollution.
It guarantees that clean water is used in a sustainable manner. efficient plumbing reduces water pollution by using less water.
Hence option a is correct.

On Saturn, the acceleration due to gravity is 11.08 m/s². On Venus, the acceleration due to gravity is 8.87 m/s². For an alien traveling to both planets, which answer is true?
A. On Venus, the alien would have less mass because the gravity is lower on Venus than on Earth.
B. On Venus, the alien would have more mass because the gravity is lower on Venus than on Earth.
C. On Saturn, the alien would weigh than on Earth because the gravity is higher on Saturn than on Earth.
D. On Saturn, the alien would weight less than on Earth because the gravity is higher on Saturn than on Earth.
Considering the difference between mass and weight, On Saturn, the alien would weigh higher than on Earth because the gravity is higher on Saturn than on Earth.
Difference between mass and weightMass is the amount of matter that a body contains. That is, mass is a measure of the amount of matter that the body possesses.
Weight is the action exerted by the force of gravity on the body; that is, it is a measure of the force that is caused on said body by the gravitational field. The weight is calculated by:
P= m×g
where
P = weight, in Newtons (N)m = mass, in kilograms (kg)g = gravitational constant, in (m/s²)The mass of an object will always be the same, no matter where it is located. Instead, the weight of the object will vary according to the force of gravity acting on it.
Statement correctConsidering the difference between mass and weight, the definition of weight, and that gravity on Earth has a value of 9.8 m/s², the correct answer is option C.) On Saturn, the alien would weigh higher than on Earth because the gravity is higher on Saturn than on Earth.
This can be seen in the expression for the weight calculation. Since the mass is the same both on Earth and on Saturn, if the gravity of the latter is greater, the product of mass with gravity must be greater.
