What are 3 products of the light-dependent reactions? The products of the light-dependent reactions, ATP and NADPH, have lifespans in the range of millionths of seconds, whereas the products of the light-independent reactions (carbohydrates and other forms of reduced carbon) can survive for hundreds of millions of years. What is importance of light? It seems […]
What are the 3 magnetic materials?
What are the 3 magnetic materials? Materials that can be magnetized, which are also the ones that are strongly attracted to a magnet, are called ferromagnetic (or ferrimagnetic). These include the elements iron, nickel and cobalt and their alloys, some alloys of rare-earth metals, and some naturally occurring minerals such as lodestone. Does the human […]
How does a person move forward during swimming?
How does a person move forward during swimming? A person applies force on the water in backward direction and water according to the third law of motion water apply an equal and opposite force in the forward direction which helps a person to swim. How do swimmers reduce drag? Here are ten good ways to […]
When an electron makes a transition from the N 4 to the N 2 then emitted line spectrum will be?
How do you calculate the no load speed of a DC motor?
How do you calculate the no load speed of a DC motor? By multiplying the velocity constant by the nominal motor voltage, obtain the theoretical no-load speed of the motor (zero torque and no-load speed) and plot it on the left vertical axis. Draw a straight line between this point and the stall torque and […]
Is parsec is a unit of Time?
Is parsec is a unit of Time? Unfortunately, like the similarly misused ‘light-year’, the parsec is a unit of length, not of time. A parsec is equal to about 3.26 light-years or roughly 31 trillion kilometres (19 trillion miles). The unit has its origins in one of the first methods of determining the distance to […]
Why do plants look green in color 10?
Why do plants look green in color 10? Answer: The leaves of plants contain green pigments called chlorophyll which is necessary for photosynthesis. Plants reflect green light of sunlight, so they look green. Why are some plants not green in Colour? When leaves contain high concentration of anthocyanin pigments, the leaves appear red or purple […]
Can WD 40 spontaneously combust?
Can WD 40 spontaneously combust? If the oil will cure and harden, then it is a fire hazard. WD40 won’t spontaneously combust. At what temperature does gasoline vapor ignite? 536°F. Is it safe to pressurize gasoline? 100 PSI isn’t exactly a small amount of pressure and in itself is rather dangerous. If the container bursts […]
What is the significance of reference point for measuring distance?
What is the significance of reference point for measuring distance? A reference point is a place or object used for comparison to determine if something is in motion. An object is in motion if it changes position relative to a reference point. Objects that are fixed relative to Earth – such as a building, a […]
Why is current constant in a parallel circuit?
Why is current constant in a parallel circuit? Each resistor in parallel has the same voltage of the source applied to it (voltage is constant in a parallel circuit). Parallel resistors do not each get the total current; they divide it (current is dependent on the value of each resistor and the number of total […]
