How energy is transformed in our body? All of the body processes, like digestion, pumping blood, breathing, are powered by cells converting the stored chemical energy into work and heat, in a process called respiration. Inside the muscle cells of the human (or any animal), the chemical energy is transformed (changed) into mechanical work and […]

What 4 things are needed for photosynthesis?
What 4 things are needed for photosynthesis? For photosynthesis to take place, plants need to take in carbon dioxide (from the air), water (from the ground) and light (usually from the sun). What are the three end products of photosynthesis? Glucose and oxygen are the final products of photosynthesis. We all know that photosynthesis is […]
What is the difference between a clutch and a torque converter?
What is the difference between a clutch and a torque converter? The way a torque converter operates compared to a clutch is very different. The main difference is that torque converters idle before they engage and they start to engage at around 1,700 RPM. While clutches engage earlier, they have a slip range at about […]
Are water slides dangerous?
Are water slides dangerous? Water slides are the number one cause of injuries at water parks. So, follow ride directions. Rules like “feet first” are there for a reason―to keep riders safe. Can you fall out of a water slide? It’s the water running down the slide, creating an almost frictionless surface, that makes this […]
How do birds stay in the air?
How do birds stay in the air? Flapping: When birds flap, the stroke of their downbeat moves the wing tips forward and downward. And as they move forward, the rush of air on their airfoil wings causes more lift. But because flapping birds have smaller wings than soaring birds, they must move forward faster to […]

Is there a lava planet?
Is there a lava planet? There are no known lava worlds in the Solar System and the existence of extrasolar lava planets remains theoretical. Several known exoplanets are likely lava worlds, given their small enough masses, sizes, and orbits. Likely lava exoplanets include COROT-7b, Kepler-10b, and Kepler-78b. Who named Uranus the planet? Johann Elert Bode […]
How long do lead aprons last?
How long do lead aprons last? 10 years How often should lead aprons be checked? Lead aprons should be checked fluoroscopically at least on an annual basis for their shielding integrity. Rejecting an apron depends on the location, area size and number of flaws. It is best to keep the number of flaws to a […]
