How do you calculate the change in liquid temperature? This is easy. You subtract the final temperature from the starting temperature to find the difference. So if something starts at 50 degrees Celsius and finishes at 75 degrees C, then the change in temperature is 75 degrees C – 50 degrees C = 25 degrees […]
Does grass stop erosion?
Does grass stop erosion? Grasses native to your region will help build soil stability. Native grasses grow long roots that tie the topsoil and subsoil together. Buffer strips, or swathes of native species, are a great way to reduce erosion and sedimentation. An added bonus is using plants that can attract pollinators and increase biodiversity. […]
What is the change in velocity per time?
What is the difference between radar and Doppler radar?
What is the difference between radar and Doppler radar? How is Doppler different from conventional radar? Conventional radar detects the presence of dense objects (such as precipitation) in the field, while the Doppler system detects a phase shift between the outgoing and incoming signals. What does a tornado look like on Doppler radar? Meteorologists look […]
What are the similarities and differences between primary and secondary succession?
What are the similarities and differences between primary and secondary succession? Explanation: Primary succession occurs in an environment without previous life, or a barren habitat. Secondary succession occurs in an area that had previously been inhabited but experienced a disturbance, such as a wildfire. The newly created volcanic island has no previous life, and is […]
Do lions attack humans?
Do lions attack humans? Cases in Lindi have been documented where lions seize humans from the centre of substantial villages. It is estimated that over 250 people are killed by lions every year. Man-eating lions studies indicate that African lions eat humans as a supplement to other food, not as a last resort. Do lions […]
Is a potential energy?
Is a potential energy? Potential energy, stored energy that depends upon the relative position of various parts of a system. A spring has more potential energy when it is compressed or stretched. A steel ball has more potential energy raised above the ground than it has after falling to Earth. What are the units of […]
Can a referee change his decision after final whistle?
Can a referee change his decision after final whistle? The referee may only change a decision on realising that it is incorrect or, at his discretion, on the advice of an assistant referee or the fourth official, provided that he has not restarted play or terminated the match. If play has not restarted, the referee […]
Do metallic bonds dissolve in water?
Do metallic bonds dissolve in water? Metallic bonds are not soluble in water because: They are held together by strong metallic bonds and so no solvent to solute attractions could be stronger than these, so these substances are insoluble also they don’t have the necessary intermolecular forces (namely hydrogen bonds) that are present in water. […]
Do I need to know Physics 1 Physics 2?
Do I need to know Physics 1 Physics 2? All you need to know for Physics 1 (newtonian mechanics) is basic derivatives for velocity and acceleration as well as some integrals for force, work and some moment of inertia problems. Physics 2 requires Calc 2 because you need to know different types of integrals such […]
