Explanation:
An electrical circuit needs:
a source of electrical power (this could be a power plant or a battery)
a material along which the electricity can flow (this may be a copper wire)
something to power (this could be a bulb)
The circuit is connected in a loop. Then, the source of power pushes electrons around the wire. It lights the bulb and continues in the circuit until it is broken.
A simple circuit lights one bulb. More difficult circuits might have several switches and loops. This would allow different groups of lights to be turned on or off at the same time.

What is the force two changed objects exert on one another if they are 9 meters apart and one has a charge of 2.5 x 10^-6 C and the second has a charge 0f 4.5 x 10^-7 C
Answer:
The force exerted between the two charges is 0.0001248N
Explanation:
we will be using Columb's law to solve this problem.
Columb's law explains that the Force between two charged bodies is directly proportional to the product of their charges and inversely proportional to the square of the distance between them.
Mathematically,
[tex]F = K\frac{Q_1 \times Q_2}{r^2}[/tex]
WHere K = constant of proportionality = [tex]8.9875 \times 10^9 N m^2/c^2[/tex]
[tex]F = 8.9875 \times 10^9 \times\frac{2.5 \times10^{-6} \times 4.5 \times 10^{-7}}{9^2}= 0.0001248N[/tex]
The force exerted between the two charges is 0.0001248N
why are the effects of collision different if the forces on the object is the same
Answer:
When two objects collide, a force is exerted on each object. The two forces are in opposite directions but the same strength. Even though the force on each object in a collision is the same strength, the objects will have different velocity changes if their masses are different.

Two runners ran side by side, each holding one end of a horizontal pole. How would this affect the direction of the runners? Explain.
Answer:
They will run parallel to each other as the none of a straight pole cannot be bent in such a way where one side can turn without the other turning.
How many hydrogen atoms are there in one molecule of PH3?
Answer:
On molecules of PH3, there has to be 3 atoms.
Explanation:
The Element Hydrogen (H) has 3 attoms.
The Element Phosphorus (P) has 1 atom.
These two created into the molecule PH3, would have to have only 3 attoms because they are asking how many hydrogens atoms are in the molecule PH3.

2.Write the formula associating energy with power
3.Write the formula associating potential energy with height.
(PLEASE HELP ASAP )
Explanation:
2. Power is defined as the rate of doing work. Mathematically, it can be given by :
[tex]P=\dfrac{W}{t}[/tex]
Where
W is work done or energy
t is the time taken
3. The formula of potential energy can be given by :
[tex]P=mgh[/tex]
Where
m is the mass of the object
g is the acceleration due to gravity
h is height
Hence, this is the required solution.

What is the momentum of a tank with a mass of 3,500 kg and a velocity of 6 m/s?
Answer: 21000 kg*m/s
Explanation: Momentum is mass times velocity or p=mv where p represents momentum so...
3,500kg*6m/s= 21,000kg*m/s

laser light has a great deal of______ a. chemical b. heat c. potential d. sound energy.??
Answer:
b. heat
Explanation:
Laser light has a great deal of heat energy. The correct option is B.
What is laser light?A laser is a device that emits light via an optical amplification process that is based on the stimulated emission of electromagnetic radiation. Light amplification by stimulated emission of radiation is an acronym for the term.
A laser generates a very narrow beam of light that can be used in a variety of technologies and instruments. Laser is an acronym that stands for Light Amplification by Stimulated Emission of Radiation.
The radiation coming from the laser light has a large amount of heat due to the presence of the electrons streamed in the form of an electromagnetic wave.

5. Relationships in a community can be cooperative or competitive.
True
False
Answer:
True
Explanation:
is the correct answer
Answer:
This is True
Explanation:
Communities cooperate by simply co-existing and working together to benefit the community and offering their goods and services. Some programs in a community offer social work, like volunteering and charities, which help people in need in a community.
They can also be competitive because there are lots of the same goods and services offered throughout the city, so businesses have to compete for sales to attract consumers in the communities.
