What is the light spectrum called? The visible spectrum is the portion of the electromagnetic spectrum that is visible to the human eye. Electromagnetic radiation in this range of wavelengths is called visible light or simply light. What is the meaning of 2020 vision? 20/20 vision is a term used to express normal visual acuity […]
What type of energy is stored in an unlit match?
What type of energy is stored in an unlit match? potential energy Which best explains Taros error? Which best explains Taro’s error? The total energy of the system remains the same. The human body stores chemical energy from digested food. Some of the chemical energy is converted into mechanical energy when the body moves. Which […]
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 […]
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 […]

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 […]
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 […]
Can mitosis ever be used for human reproduction?
Can mitosis ever be used for human reproduction? In single-cell organisms, mitosis is the only form of cellular reproduction. One round of mitosis yields two genetically identical cells. This is classified as asexual reproduction because it does not require sex for the creation of new organisms. What cells does mitosis not occur in? You read […]
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 […]
Is Lemon juice is a good conductor of electricity?
Is Lemon juice is a good conductor of electricity? When lemon juice is added to water, the acid dissociates into anions and cations which are charged. Hence they can conduct electricity as these charged particles are able to flow inside the acid. Hence when the salt or lemon juice is mixed in distilled water it […]
