How did Joseph save Egypt? Joseph collected all the food produced in those seven years of abundance in Egypt and stored it in the cities. When all Egypt began to feel the famine, the people cried to Pharaoh for food. Then Pharaoh told all the Egyptians, “Go to Joseph and do what he tells you.” […]
Do astronomers use chemistry?
Do astronomers use chemistry? By comparing astronomical observations with laboratory measurements, astrochemists can infer the elemental abundances, chemical composition, and temperatures of stars and interstellar clouds. Do you need chemistry for astronomy? Astronomy is a unique subject because it deals with such a vast mixture of topics – the very reason why many people find […]
What muffles sound the best?
What muffles sound the best? The best types of surfaces for absorbing sounds are ones with jagged surfaces and hollow recesses within (much like a sponge or cardboard). The proper object captures the sound waves and bounces them around within the object until the vibrations dwindle. Does Styrofoam deaden sound? Polystyrene foams such as Styrofoam […]
What do we call a ramp and ladder combined?
What do we call a ramp and ladder combined? A wedge is a simple machine that is made of two inclined planes together. Inclined planes don’t move, but wedges do. An axe is an example of a wedge. Inclined planes are simple machines used to make work easier. Ramps, ladders, and staircases are all inclined […]
What is the direction of the induced current in the circular loop of radius r?
What is the direction of the induced current in the circular loop of radius r? The direction of induced current in the circular loop will be clockwise or anti-clockwise depending upon the direction of current in the straight wire. The amount of induced current will be decided by the velocity with which the loop is […]
Why is gravity a non-contact force?
Why is gravity a non-contact force? Magnetism is an example of a non-contact or action-at-a-distance force. These are forces which can act on an object without being in physical contact with it. The force of gravity is another example. Thus, gravity will pull a raindrop down to Earth without any tangible physical link between the […]
What are the possible values of n and ML for an electron in a 4 d orbital?
What phase are cells in when they are not dividing?
What are the six main structures of the central nervous system?
What are the six main structures of the central nervous system? These include structures such as the frontal and temporal lobes, the thalamus, the cerebellum, the putamen, mamillary bodies and fornix, and a convolution above the corpus callosum known as the cingulate gyrus. What are the different types of neurons of the central nervous system? […]
What are three factors that affect the flow of current in a circuit?
What are three factors that affect the flow of current in a circuit? Answer. Answer: Voltage, resistance, and whether the circuit is wired in series or parallel. The current in a circuit depends on the applied voltage and the resistance of the circuit. Why do we say current flows from positive to negative? The direction […]
