Is Zenith the North Star? Sign up for our free daily newsletter today! We in the Northern Hemisphere are particularly lucky to have Polaris, a moderately-bright star, closely marking the north celestial pole – the point in the starry sky that’s at zenith (directly overhead) at the Earth’s North Pole. What are the 3 celestial […]
What fertilizer makes plants grow faster?
What fertilizer makes plants grow faster? High-nitrogen fertilizers are known for causing huge growth in plants, which is why many types are rich in nitrogen or include it as the main component. Fertilizers high in nitrogen will also restore bright green hues to your foliage. Which fertilizer works best? Best all-purpose fertilizers Jack’s Classic 20-20-20 […]
Is Phosphorus 32 Harmful?
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 […]
What is the most common energy conversion?
What is the most common energy conversion? kinetic energy How does insulation stop unwanted energy transfers? Energy loss through walls can be reduced using cavity wall insulation. This involves blowing insulating material into the gap between the brick and the inside wall, which reduces the loss by air circulating inside the cavity, therefore reducing loss […]
Why do we not see the other side of the moon?
Why is there no friction on ice?
Why is there no friction on ice? One of these theories is that friction causes the liquid layer of water to form on ice. Friction is the force that generates heat whenever two objects slide against each other. If you stand on ice without moving, no friction exists to generate heat, yet the ice is […]
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. However, if your electrical use load (radio, lights, fan, etc) exceeds the amount of charge the battery is receiving from the alternator, you will end up with a […]
What happens when zinc reacts with HCl?
What happens when zinc reacts with HCl? When zinc reacts with hydrochloric acid it produces zinc chloride and hydrogen gas. Is Zn and HCl a chemical reaction? 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 […]
Which sublevel is the lowest in energy?
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 […]
