What are emission spectrums used for? A spectroscope can be used to determine which frequencies have been emitted by a substance. The emission spectrum is a combination of the atomic spectra of the various kinds of atoms making up the substance and can be analyzed to determine the substance’s chemical or atomic composition. What do […]
Why is a decrease in GDP bad?
Why is a decrease in GDP bad? When GDP goes up, the economy is generally thought to be doing well. Meanwhile, weak growth signals that the economy is doing poorly. If GDP falls from one quarter to the next then growth is negative. This often brings with it falling incomes, lower consumption and job cuts. […]
What does the odometer of an automobile measure which of the following is moving faster?
What does the odometer of an automobile measure which of the following is moving faster? Odometer is an instrument used to calculate the distance travelled by an vehicle in particular period of time. The car will move faster as the speed is in km/hr. How do we calculate the average speed of a car? How […]

How does high voltage reduce power loss?
How does high voltage reduce power loss? High voltage transmission minimizes the amount of power lost as electricity flows from one location to the next. The higher the voltage, the lower the current. The lower the current, the lower the resistance losses in the conductors. And when resistance losses are low, energy losses are low […]
What is the average wpm for a 13-year-old?
What is the relation between current and resistance?
What is the relation between current and resistance? The relationship between current, voltage and resistance is expressed by Ohm’s Law. This states that the current flowing in a circuit is directly proportional to the applied voltage and inversely proportional to the resistance of the circuit, provided the temperature remains constant. What is a specific resistance? […]
Can you open a safe with a rare earth magnet?
What are the six sensory receptors?
What are the six sensory receptors? Sensory receptors exist in all layers of the skin. There are six different types of mechanoreceptors detecting innocuous stimuli in the skin: those around hair follicles, Pacinian corpuscles, Meissner corpuscles, Merkel complexes, Ruffini corpuscles, and C-fiber LTM (low threshold mechanoreceptors). What do all receptors have in common? What do […]
