If u speed up from rest to 12 m/s in 3 seconds, what is your acceleration

Answers

Answer 1
Answer: 4

Just divide 12 by 3, so if it takes 3 seconds, then every second, it goes up 4.
Answer 2
Answer: Acceleration = change in speed/time

Therefore it is 4m/s squared

Compare and contrast ultraviolet light with infrared light using wavelength, frequency, and energy.

Answers

Ultraviolet light has a shorter wavelength (in its majority), higher frequency and emits higher amounts of energy than infrared. More specifically, the UV and infrared values are shown below: Ultraviolet Wavelength: From 10 nm to 380 nm Frequency: From 30 PHz to 750 THz Energy: From 3.1 eV to 124 eV Infrared Wavelength: From 1 mm to 750 nm Frequency: From 300 GHz to 430 THz Energy: From 0.0012 eV to 1.65 eV

Final answer:

Ultraviolet light has a shorter wavelength and higher frequency than infrared light. It also has more energy. Violet light, which is part of the ultraviolet spectrum, has a higher frequency and shorter wavelength than red light. Infrared radiation, on the other hand, has longer wavelengths and lower frequencies than violet light.

Explanation:

Ultraviolet light and infrared light are both forms of electromagnetic radiation, but they differ in terms of wavelength, frequency, and energy. Ultraviolet light has a shorter wavelength and higher frequency compared to infrared light. As a result, ultraviolet light has more energy than infrared light.

For example, violet light, which is part of the ultraviolet spectrum, has a higher frequency and shorter wavelength than red light. Ultraviolet radiation extends from about 400 nm to 10 nm and is produced by atomic and molecular motions and electronic transitions. In contrast, infrared radiation has longer wavelengths and lower frequencies than violet light.

It's important to note that shorter-wavelength ultraviolet light can cause damage to living cells and is better able to cause materials to fluoresce compared to visible light. On the other hand, infrared radiation is often associated with heat and is used for various purposes, such as remote control communication and thermal imaging.

What happens during mitosis? During mitosis, a eukaryotic cell undergoes a carefully coordinated nuclear division that results in the formation of two genetically identical daughter cells. Mitosis itself consists of five active steps, or phases: prophase, prometaphase, metaphase, anaphase, and telophase.

Explain the scientific meaning of the word random

Answers

Explanation:

In general the word random means by chance. The event that occurs unknowingly rather than according to plan is called at its randomness.

But in science, the word random relates with a type of event that is described by its probability distribution.

Also, random means the entropy of the system i.e. it is a thermodynamic quantity that represents the amount of energy in the system that is unavailable for doing work.
