How long will this solar minimum last? Scientists say the Sun may be going through a long period of decreased activity known as the Modern Grand Solar Minimum from 2020 to 2053. Are sunspots hotter or cooler? Sunspots are darker, cooler areas on the surface of the sun in a region called the photosphere. The […]

Are pressure and volume directly related?
Are pressure and volume directly related? Key Concepts and Summary The volume of a given gas sample is directly proportional to its absolute temperature at constant pressure (Charles’s law). The volume of a given amount of gas is inversely proportional to its pressure when temperature is held constant (Boyle’s law). What happens to pressure when […]

What is the relationship between amplitude and period of a pendulum?
What is the relationship between amplitude and period of a pendulum? The longer the length of string, the farther the pendulum falls; and therefore, the longer the period, or back and forth swing of the pendulum. The greater the amplitude, or angle, the farther the pendulum falls; and therefore, the longer the period.) Does frequency […]

Can two vectors of unequal magnitude ever sum to zero?
Can two vectors of unequal magnitude ever sum to zero? Yes, two vectors of equal magnitude that are pointing in opposite directions will sum to zero. Two vectors of unequal magnitude can never sum to zero. If they point along the same line, since their magnitudes are different, the sum will not be zero. Does […]
Why do protons stick together in a nucleus?
Why do protons stick together in a nucleus? The strong nuclear force pulls together protons and neutrons in the nucleus. At very small distances only, such as those inside the nucleus, this strong force overcomes the electromagnetic force, and prevents the electrical repulsion of protons from blowing the nucleus apart. How does an atom hold […]
