How can an object accelerate towards the center without getting closer to the center? If an object is in uniform circular motion, then it is accelerating towards the center of the circle; yet the object never gets any closer to the center of the circle. It maintains a circular path at a constant radius from […]

What is the raw materials and end products of photosynthesis? The raw materials of photosynthesis, water and carbon dioxide, enter the cells of the leaf, […]
Which best describes the motion of an object?
Which best describes the motion of an object? You can describe the motion of an object by its position, speed, direction, and acceleration. An object is moving if its position relative to a fixed point is changing. Even things that appear to be at rest move. Which formula is used to find an objects acceleration? […]
What type of ozone is bad?
What type of ozone is bad? Stratospheric ozone is “good” because it protects living things from ultraviolet radiation from the sun. Ground-level ozone, the topic of this website, is “bad” because it can trigger a variety of health problems, particularly for children, the elderly, and people of all ages who have lung diseases such as […]

Why we should not ban smoking?
Why we should not ban smoking? Scientists agree that smoking is dangerous. Tobacco smoke can cause cancer, strokes and heart disease.

Can you diffract a human?
Can you diffract a human? Since Plank’s constant is on the order of 10-34, the de Broglie wavelength is virtually undetectable for large amounts of matter. There is much evidence of matter possessing such a de Broglie wavelength. Well, theoretically, since all matter possess wave-like properties, so do humans, and cats, and whatever you please. […]
