Explanation:
[tex]3 \times 200 \div 5[/tex]
Answer:
The wavelength of the wave can be calculated using the equation λ = 2L/n, where L is the distance between two compressions and n is the number of compressions. In this case, the distance between compressions is 200 cm and the number of compressions is 3, so the wavelength is 133.3 cm.
The drawing shows a student holding two negatively charged balloons. What is most likely to occur if the student brings the balloons closer to each other?
A The magnitude of the electrostatic force between the balloons will decrease, and they will attract each other.
B The magnitude of the electrostatic force between the balloons will increase, and they will attract each other.
C The magnitude of the electrostatic force between the balloons will decrease, and they will repel each other.
D The magnitude of the electrostatic force between the balloons will increase, and they will repel each other.
Answer:
D
Explanation:
"Like charges repel each other; unlike charges attract. Thus, two negative charges repel one another, while a positive charge attracts a negative charge. The attraction or repulsion acts along the line between the two charges."

If the student brings two negatively charged balloons closer to each other magnitude of the electrostatic force increases and they will repel each other. The Correct option is D.
What is Electrostatic force?Electrostatic force is a force of attraction or repulsion between two unlike or like charges respectively. when like charges come closer to each other, they gets repel by one another and it gets attracted for unlike charges. Force of attraction or repulsion between two point charges are given by coulomb's law, which states that " The force of attraction or repulsion between two charges are directly proportional to product of magnitude of two charges and inversely proportional to square of distance between them.
Charged bullions has charges accumulated on the surface. when two negative charged balloons comes closer they gets repelled each other.
Hence option D is correct

PLEASE HELP ASAP! Any absurd answers will be reported. NO LINKS, IDC IF ITS THE ONLY WAY TO GET AN ANSWER.
Answer:
There is a thing called a continental drift. It started about 200 million years ago. At first the continents were all attached, this super continent was called pangaea. Continental drift occurs because of the shift of the tectonic plates within the earth's outer shell. The heat from within the earth triggers movement to occur. This a very slow process though. It took 200 million years for the continents to get where the are now and would probably take another 200 to collide.

How do the laws of evolution explain how convergent evolution occurs?
How does convergent evolution happen?
Convergent evolution is similar to parallel evolution, which occurs when two independent species evolve in the same direction and thus independently acquire similar characteristics; for instance, gliding frogs have evolved in parallel from multiple types of tree frog.
Convergent evolution is when different organisms independently evolve similar traits. For example, sharks and dolphins look relatively similar despite being entirely unrelated. ... Another lineage stayed put in the ocean, undergoing tweaks to become the modern shark.

Sound waves are moving across the room from the left toward the opening. What happens to the sound waves as they hit the wall with an opening A Some of the sound waves refract off the wall, while other waves will move through the small opening and then spread out. This is called diffraction. B. Some of the sound waves will reflect off the wall, while others will difract trough the opening and spread out. C Most of the sound waves will reflect ofr the wall, while others will diffract through the opening and spread out. D. Most of the sound waves will reflect off the wall, while others will squeeze through the opening and then reflect again.
Answer: C is right
Explanation: Most of the sound waves are reflected back but waves passing opening will speread to all directions outside because of diffraction

A student rubs a rubber rod with fur, producing a negative charge on the rod. The student then touches the rod to a hollow, neutral metal sphere that stands on an insulating plastic stand. This transfers negative charges from the rod to the sphere: Which statement best predicts what will happen to the charge, and why?
A It will distribute itself evenly over the surface of the sphere, because like charges repel and the sphere is a conductor.
B It will remain at the point of contact between the rod and the sphere, because resistance in the metal prevents the charges from easily moving.
C It will slowly drift to the bottom of the sphere, because the charges rapidly attach to individual atoms, making them slightly heavier than surrounding atoms.
D It will quickly spread to the air around the sphere, because it will seek to occupy as large a volume of neutral matter as possible.
Answer:
B It will remain at the point of contact between the rod and the sphere, because resistance in the metal prevents the charges from easily moving.
Explanation:
The rubber rod will distribute itself evenly over the surface of the sphere, because like charges repel and the sphere is a conductor. So, the correct option is A.
What is Conductor?A conductor is defined as an object or type of material that allows the flow of charge in one or more directions where materials made of metals are common electrical conductors. The property of conductors that allows them to conduct electricity is called conductivity while the flow of electrons in a conductor is called electric current.
In the given example, the rubber rod will distribute itself evenly over the surface of the sphere, because like charges repel and the sphere is a conductor. Some common conductors examples are copper, aluminum, gold, and silver.
Therefore, the correct option is A.
