Is Nuclear Physics a good career? For academic research jobs, nuclear physics may well be a better choice, while the opportunity to design real-world solutions to power generation and medical problems is a major benefit of studying nuclear engineering. Is nuclear physics harmful to humans? Nuclear radiation can ionise chemicals within a body, which changes […]

Which part of California has the most earthquakes? Central Valley South The San Andreas fault system is the major geologic boundary between the North American and Pacific tectonic plates and passes through much of the state. It will create the biggest earthquakes—as big as magnitude 8—that will disrupt the whole region. What is the most […]

What does crying do to your skin? “Typically, tears are made from water, toxins, lysozyme, salt, lipids, and more,” she says. “Lysozyme, in particular, is an enzyme that helps get rid of bacteria, and, theoretically, it can combat against acne and other bacteria found on the face. Also, the salt content from tears can dry […]

Why do we wave on Zoom calls? “The hand wave just says we’re done,” Rosen said. “Our instinct is we need to close and complete that loop. In person, we can close it with our words, but that doesn’t work in a large meeting on Zoom.” The gesture is a regression to basics of sorts, […]

When a charged particle moves in a straight line a magnetic field is? Figure 11.4. 2: A charged particle moving with a velocity not in the same direction as the magnetic field. The velocity component perpendicular to the magnetic field creates circular motion, whereas the component of the velocity parallel to the field moves the […]

Why do frets get closer together? When you stop the string with your finger, and pluck a note, you’re shortening the length of the string, which makes the frequency (and the pitch) go up. The wavelengths are spaced closer together as the frequencies become higher, so the frets have to be closer together to match […]

What are significant figures explain with examples? All non-zero digits are considered significant. For example, 91 has two significant figures (9 and 1), while 123.45 has five significant figures (1, 2, 3, 4, and 5). Zeros appearing between two non-zero digits (trapped zeros) are significant. Example: 101.12 has five significant figures: 1, 0, 1, 1, […]

Can plants see color? ‘Invisible’ light Although plants are a bit color blind, they do sense colors, more appropriately energy levels, that are entirely invisible to us humans. For example, plants can perceive far-red light. Plants often utilize the red to far-red relationship. How far should plants be from grow lights? 16-36 inches Is 24 […]

Can you sue for consequential damages? CONSEQUENTIAL DAMAGES: If you can prove that the other party knew or could have foreseen when the agreement was made, you can recover consequential damages. One common issue in a breach of contract case regarding consequential damages is whether you can recover for lost profits. Should I waive consequential […]

Can a body have 0 velocity and still be accelerating? Yes, an object can have zero velocity and still be accelerating simultaneously. Then the object will start to move in the backward direction. Can a body have zero velocity and finite acceleration? This acceleration is the gravitational acceleration. At that point the component of acceleration/gravitational […]
