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 […]
Are the layers still horizontal or are they bent Why?
Are the layers still horizontal or are they bent Why? Answer. Answer: Figure 10.6: Rocks that were originally deposited in horizontal layers can subsequently deform by tectonic forces into folds and faults. Folds constitute the twists and bends in rocks. How is horizontal unconformity formed? An angular unconformity is an unconformity where horizontally parallel strata […]
What is a Sharks sixth sense called?
What is a Sharks sixth sense called? A Shark’s Sixth Sense around their head called ampullae of Lorenzini. These are jelly filled pores that go down to the nerve receptors at the base of the dermis. They are specialized electroreceptor organs that allow the shark to sense electromagnetic fields and temperature changes in the water […]
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 […]
Which of the following would be the best soil for gardening 2 points?
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 […]
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 is the main cause of ozone depletion?
What is the main cause of ozone depletion? Ozone depletion occurs when chlorofluorocarbons (CFCs) and halons—gases formerly found in aerosol spray cans and refrigerants—are released into the atmosphere (see details below). CFCs and halons cause chemical reactions that break down ozone molecules, reducing ozone’s ultraviolet radiation-absorbing capacity. Is inhaling ozone bad? Whether in its pure […]
