The answer to this question is False
Answer: Electromagnetic waves (Ultraviolet light, between 100 nm and 380 nm)
Explanation:
Solar cells work by the photoelectric effect, which consists of the emission of electrons (electric current) when light (electromagnetic waves) falls on a metal surface under certain conditions.
In this sense, the portion of the electromagnetic spectrum this cells use is Ultraviolet light (UV) from the Sun, whose wavelength is approximately between 100 nm and 380 nm.
It is important to note, this is a type of electromagnetic radiation that is not visible to the human eye.
Let's first convert the initial and final speed of the vehicle in m/s:
Therefore, the acceleration of the car is given by
And so now we can calculate the force required by using Newton's second law:
Answer:
The answer is B
Explanation:
There are many Federal laws that help government tell scientist what is ethical and unethical.
