Is it better to be under or over weight? People who are clinically underweight face an even higher risk for dying than obese individuals, the study shows. Compared to normal-weight folks, the excessively thin have nearly twice the risk of death, researchers concluded after reviewing more than 50 prior studies. How can you tell if […]
Why is botulism so rare?
Why is botulism so rare? Spores are not killed by boiling, but botulism is uncommon because special, rarely obtained conditions are necessary for botulinum toxin production from C. botulinum spores, including an anaerobic, low-salt, low-acid, low-sugar environment at ambient temperatures. Can you survive botulism? Although botulism can cause severe and prolonged symptoms, most people recover […]
Is there forces of attraction among the particles in all matter?
Is there forces of attraction among the particles in all matter? Particles of matter of the same substance, such as the same element, are attracted to one another. The force of attraction tends to pull the particles closer together. The particles need a lot of kinetic energy to overcome the force of attraction and move […]

Why is AC current used in homes?
Why is AC current used in homes? Why we use AC voltage in our homes despite DC voltage gaining traction. Simply put, AC voltage is capable of converting voltage levels with just a transformer, making it far easier to transport across great distance than DC, whose conversion requires more complex electronic circuitry. How do I […]

What does Lenz law state?
What does Lenz law state? Lenz’s law, in electromagnetism, statement that an induced electric current flows in a direction such that the current opposes the change that induced it. This law was deduced in 1834 by the Russian physicist Heinrich Friedrich Emil Lenz (1804–65). Lenz’s law. What are the four Maxwell’s equations? The statements of […]
