According to a report from Check Point, a software security firm, the lights contained a vulnerability that would allow for a hacker to not only turn them off and on but could potentially allow someone to install malware on my computer and network using the lights as a gateway […]

What is the velocity of a body in circular motion? Since the body describes circular motion, its distance from the axis of rotation remains constant at all times. Though the body’s speed is constant, its velocity is not constant: velocity, a vector quantity, depends on both the body’s speed and its direction of travel. Can […]

What are the big ideas of physical science? Among the physical sciences are astronomy, which studies the universe beyond Earth; physics, which studies matter and energy and their interactions; chemistry, which studies the properties of substances and how they change; and the Earth sciences, which study Earth itself as well as its atmosphere and waters. […]

How do volcanoes affect humans and the environment? Fast-moving lava can kill people and falling ash can make it hard for them to breathe. They can also die from famine, fires and earthquakes which can be related to volcanoes. People can lose their possessions as volcanoes can destroy houses, roads and fields. Lava can kill […]

What happens when the frequency of a sound wave decreases? If frequency decreases, pitch decreases and produces a lower sound. Frequency and wavelength are inversely related, meaning that if frequency increases, wavelength becomes shorter and vice versa. Therefore, if frequency increases, pitch increases and creates a higher sound and wavelengths become shorter. Why is sound […]

What are the similarities and differences between cellular respiration and fermentation? Describe the similarities and differences between cellular respiration and fermentation. Both produce ATP through the breakdown of carbon based molecules, and both allow glycolysis to continue by recycling electron acceptors. Cellular Respiration requires oxygen and produces much more ATP than fermentation. What are 3 […]
