Is Phosphorus 32 Harmful? Phosphorus-32 is an energetic beta emitter which can penetrate up to 0.8 cm into living skin tissue. Therefore, this isotope poses an external (skin) dose hazard to persons as well as a potential internal hazard. What type of radioactive decay does phosphorus-32 go through? Phosphorus-32 is a commonly used radionuclide with […]
Does car battery charge while in park?
Does car battery charge while in park? Yes, the alternator does charge the battery while the car is idling – regardless of the load on the battery.

When zinc reacts with hydrochloric acid, the reaction bubbles vigorously as hydrogen gas is produced. The production of a gas is also an indication that a chemical reaction […]
What is the order of structures that oxygen passes through?
What is the order of structures that oxygen passes through? Air then travels down the pharynx and larynx, through the trachea, and into the lungs. In the lungs, air passes through the branching bronchi, reaching the respiratory bronchioles. The respiratory bronchioles open up into the alveolar ducts, alveolar sacs, and alveoli. What is the pathway […]
What are the limitations of Einstein theory of specific heat?
What are the limitations of Einstein theory of specific heat? The correct statement is that Einstein’s law fails to account for the low temperature behavior of specific heat of solids, even qualitatively, but at high temperature it goes to the Dulong and Petit law limit, which is an accurate description of the specific heat of […]

What is broaching in machining?
What is broaching in machining? Broaching is a machining process using a cutting tool with teeth that increase in size from front to back.

Is Bacteria living or nonliving?
Is Bacteria living or nonliving? Bacteria (singular: bacterium) are a major group of living organisms. Most are microscopic and unicellular, with a relatively simple cell structure lacking a cell nucleus, and organelles such as mitochondria and chloroplasts. Bacteria are the most abundant of all organisms. Do antibiotics weaken immune system? Will antibiotics weaken my immune […]
