How long does a nuclear core last?
How long does a nuclear core last? U.S. nuclear plants are proving that age is really just a number. As the average age of American reactors approaches 40 years old, experts say there are no technical limits to these units churning out clean and reliable energy for an additional 40 years or longer. What happens […]
How much heat is trapped in the atmosphere?
How much heat is trapped in the atmosphere? Earth’s surface warms up in the sunlight. At night, Earth’s surface cools, releasing heat back into the air. But some of the heat is trapped by the greenhouse gases in the atmosphere. That’s what keeps our Earth a warm and cozy 58 degrees Fahrenheit (14 degrees Celsius), […]
Is the movement of electrically charged particles?
Is the movement of electrically charged particles? Electric current, any movement of electric charge carriers, such as subatomic charged particles (e.g., electrons having negative charge, protons having positive charge), ions (atoms that have lost or gained one or more electrons), or holes (electron deficiencies that may be thought of as positive particles). How does charge […]

What happens when two waves of different frequencies are added together?
What happens when two waves of different frequencies are added together? When two waves of similar frequency arrive at the same point and superimpose, they alternately constructively and destructively interfere. This alternating is known as a beat because it produces an unpleasant pulsing sound. This varying loudness occurs because the sound waves have similar but […]
What are three types of projectiles?
What are three types of projectiles? Three types of projectiles— the bullet, the round ball, and shot—are used in muzzleloaders. How do projectiles behave? A projectile is an object upon which the only force is gravity. Gravity acts to influence the vertical motion of the projectile, thus causing a vertical acceleration. Horizontal forces are not […]
