Is photoelectric effect possible at all frequencies? Hence, we can say that photoelectric emission only occurs when the frequency of the incident radiation is greater than the threshold frequency or we can say that photoelectric emission does not occur at all frequencies. Why photoelectric effect is not possible at all frequencies? so as we decrease […]
What if the sun disappeared for 1 second?
What if the sun disappeared for 1 second? If the sun disappeared for ONLY ONE SECOND, nobody would notice anything other than no light for a single second. Nothing else. Our orbit would change by less than 1 Km as I’ve shown. What happens if the moon dies? Destroying the Moon would send debris to […]
Which is the reference direction?
Which is the reference direction? A reference point is a starting point used to describe the position of an object. What is reference direction? The reference direction is the direction you must travel from the reference point toward an object. Displacement is the difference between the initial position and the final position of an object. […]
What is the main transformation that occurs during glycolysis?
What is the main transformation that occurs during glycolysis? Phosphofructokinase speeds up or slows down glycolysis in response to the energy needs of the cell. Overall, glycolysis converts one six-carbon molecule of glucose into two three-carbon molecules of pyruvate. What are the products of aerobic respiration? The reaction is called aerobic respiration, and it produces […]
What are five facts about Saturn?
How spherical aberration is corrected?
How spherical aberration is corrected? Spherical aberration can be eliminated by making lenses with an aspheric surface. Descartes showed that lenses whose surfaces are well-chosen Cartesian ovals (revolved around the central symmetry axis) can perfectly image light from a point on the axis or from infinity in the direction of the axis. How do you […]
What happens if you chew a pill that is supposed to be swallowed?
What happens if you chew a pill that is supposed to be swallowed? Some medicines are specially prepared to deliver the medicine to your body slowly, over time. If these pills are crushed or chewed, or the capsules are opened before swallowing, the medicine may go into the body too fast, which can cause harm. […]
What are 3 good uses of radioactive isotopes?
What are 3 good uses of radioactive isotopes? Different chemical forms are used for brain, bone, liver, spleen and kidney imaging and also for blood flow studies. Used to locate leaks in industrial pipe lines…and in oil well studies. Used in nuclear medicine for nuclear cardiology and tumor detection. Used to study bone formation and […]
How do you find the specific heat of aluminum?
Why sea waves are high at night?
Why sea waves are high at night? High tides and low tides are caused by the moon. The moon’s gravitational pull generates something called the tidal force. The tidal force causes Earth—and its water—to bulge out on the side closest to the moon and the side farthest from the moon. These bulges of water are […]
