The distance between the 2nd compression and the 3rd compression in a longitudinal wave is 200 cm. Find the wavelength of the wave.
I need the answer with working and formula..
Class - 8, Ch:13 - Sound, NCERT, CBSE

Answers

Answer 1

Explanation:

[tex]3 \times 200 \div 5[/tex]

Answer 2

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.

Answers

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

How do the laws of evolution explain how convergent evolution occurs?

Answers

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.
