A glass of water is placed on a record turntable. You turn the record player on and it begin to slowly increase in speed. What happens next?
What happens next factor is dependent on various factors, mainly the forces at play and their reaction with the changing environment. The following must be considered: - The outward acting force of centripetal acceleration. - The downward force of gravity and its resulting opposite normal force. The water will react due to the combined efforts of these two forces, forcing the water in a shape that is normal to this force sum. As the speed of the record player increases, the angle of the water's changing parabolic shape will steepen in respect to the increasing angular frequency of the spin. This could even cause the glass to tip over, dependent on the aspect ratio of the glass as well as the standard properties of its material.
Why should I learn C Programming?
C is the ultimate programming language for someone who wants to learn why computers do what they do. C can be high-level, meaning even someone who is non-technical can guess what is going on, or extremely close to assembly language, which is almost what the computer thinks in. C is what impresses interviewers when you start looking for jobs because it shows them you care about how fast your computer runs and how efficient your program is. It shows you know the control flow of the computer's memory organization. It shows that you are a seasoned, logical, and smart computer scientist.
What even is an Arduino board? What can it be used to make?
The Arduino is a open-source microcontroller (think mini computer) board that is used for a wide number of use cases, from elementary school science fairs to advanced hobbyists' DIY projects to my own college courses! The Arduino platform allows you to work with both hardware and software to convert sensor or user inputs, such as button presses or typed instructions, to into real-life actions or problem-solving outputs. You build your project using the Arduino as the brains and controller and then program it to do what you want to happen. Projects can be as simple as a small light for your desk to a battling hovercraft (I've actually done this!).
