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 […]
What is called self inductance?
What is called self inductance? Self-inductance: Self inductance is defined as the phenomenon in which a change in electric current in a circuit produces an induced electro-motive-force in the same circuit. What is coefficient of self inductance? Definition: coefficient of self inductance. The ratio of the back EMF to the rate of change of current […]
Does sonar affect fish?
Does sonar affect fish? It is a finding that Popper says “should not be extrapolated to other fish species or the effects of other sound sources.” There is considerable concern that human-produced (anthropogenic) sounds added to the environment could have damaging effects on marine life. What is the basic principle of sonar? Sonar are electronic […]
Which macromolecule is most important to life?
Which macromolecule is most important to life? proteins Which macromolecule has the most energy? There are four classes of biological molecules: fats, carbohydrates, proteins, and nucleic acids. Of these, fats produce the most energy per gram at a whopping nine calories per gram. Carbohydrates and proteins produce less than half of this, at only four […]
What is the process of a muscle contraction?
What is the process of a muscle contraction? Muscle contraction occurs when the thin actin and thick myosin filaments slide past each other. It is generally assumed that this process is driven by cross-bridges which extend from the myosin filaments and cyclically interact with the actin filaments as ATP is hydrolysed. What determines the strength […]
What is the #1 cancer killer?
What is the #1 cancer killer? According to the American Cancer Society, lung cancer — and lung cancer caused by asbestos — is the number one killer, with 142,670 estimated deaths in 2019 alone, making it three times deadlier than breast cancer. What’s the most curable cancer? What are the most curable cancers? Breast cancer. […]
What is the difference between the two types of igneous rocks?
What is the difference between the two types of igneous rocks? The two main categories of igneous rocks are extrusive and intrusive. Extrusive rocks are formed on the surface of the Earth from lava, which is magma that has emerged from underground. Intrusive rocks are formed from magma that cools and solidifies within the crust […]
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 […]
