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 […]
Is hail a solid or liquid?
What is the relationship between volume and pressure for a gas?
What is the relationship between volume and pressure for a gas? It is summarized in the statement now known as Boyle’s law: The volume of a given amount of gas held at constant temperature is inversely proportional to the pressure under which it is measured. Are volume and temperature directly proportional? The volume of a […]
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 […]
How is food transported in plants explain Class 10?
How is food transported in plants explain Class 10? The phloem tissue in plants transports food materials from the leaves to different parts of the plant. As a result, the osmotic pressure in the tissue increases forcing the water to move through it. This pressure moves the materials in phloem to the tissues which have […]
What is the SI base unit of mass?
What is the SI base unit of mass? kilogram (kg) What is the purpose of SI base units? The SI base units are a fundamental part of modern metrology, and thus part of the foundation of modern science and technology. The SI base units form a set of mutually independent dimensions as required by dimensional […]
What happens when an atom gains or loses an electron quizlet?
What happens when an atom gains or loses an electron quizlet? When an atom loses an electron, it loses a negative charge and becomes a positive ion. When an atom gains an electron it gains a negative charge and becomes a negative ion. What kind of bond is formed when two atoms share an electron? […]
How do electrolytic cells work?
How do electrolytic cells work? An electrolytic cell converts electrical energy into chemical energy. Here, the redox reaction is spontaneous and is responsible for the production of electrical energy. The reaction at the anode is oxidation and that at the cathode is reduction. Here, the anode is positive and cathode is the negative electrode. What […]
