What is the formula to calculate resistance? If you know the total current and the voltage across the whole circuit, you can find the total resistance using Ohm’s Law: R = V / I. For example, a parallel circuit has a voltage of 9 volts and total current of 3 amps. The total resistance RT […]

Do we drink groundwater? Groundwater supplies drinking water for 51% of the total U.S. population and 99% of the rural population. Groundwater helps grow our food. 64% of groundwater is used for irrigation to grow crops. Groundwater is a source of recharge for lakes, rivers, and wetlands. What is the groundwater cycle? Groundwater is a […]

What is it called when sensory information is detected by a sensory receptor? When sensory information is detected by a sensory receptor, sensation has occurred. Perception refers to the way sensory information is organized,interpreted, and consciously experienced. Perception involves both bottom-up and top-down processing. What happens when information is detected by sensory receptor? When sensory […]

Under what condition will the resultant of three unequal forces be zero? Answer. Explanation: If one force of 5N from one is applied and the two force of 2N and 3N is applied respectively then the resultant force will be equal to 0 . Can two vectors of unequal magnitude ever sum to zero? Yes, […]

What are 5 uses of hydrogen? Hydrogen: uses commercial fixation of nitrogen from the air in the Haber ammonia process. hydrogenation of fats and oils. methanol production, in hydrodealkylation, hydrocracking, and hydrodesulphurization. rocket fuel. welding. production of hydrochloric acid. reduction of metallic ores. Why is hydrogen important to life? The most important function of hydrogen […]

What is the main function of the cerebellum? The cerebellum is important for making postural adjustments in order to maintain balance. Through its input from vestibular receptors and proprioceptors, it modulates commands to motor neurons to compensate for shifts in body position or changes in load upon muscles. What is the main function of cerebrum? […]

How do you know if you found your soulmate? There is no test that will help you determine if you’ve found your soulmate or not. To figure it out, you just have to know it. You have to feel it in your gut, that this person is the right one for you. You should feel […]

Can jotaro beat Kars? No matter how many punches jotaro delivers on stopped time it won’t kill kars. So jotaro might put up a fight, and his time stop will be a nuisance, but kars will find a way to beat him eventually. Jotaro has no way of killing or containing kars. Can jotaro beat […]

Can we remove CO2 from the air? Using reforestation to remove CO2 One planned measure to stop too much CO2 from being released into the atmosphere is reforestation. According to studies, 3.6 billion tons of CO2 — around 10% of current CO2 emissions — could be saved every year during the growth phase. Do oceans […]

What does a higher absolute magnitude mean? The scale for absolute magnitude is the same as that for apparent magnitude, that is a difference of 1 magnitude = 2.512 times difference in brightness. This logarithmic scale is also open-ended and unitless. Again, the lower or more negative the value of M, the brighter the star […]
