How do you find the amplitude of a sound wave? Amplitude is generally calculated by looking on a graph of a wave and measuring the height of the wave from the resting position. The amplitude is a measure of the strength or intensity of the wave. For example, when looking at a sound wave, the […]
Do neutron bombs exist?
Do neutron bombs exist? A neutron bomb is actually a small thermonuclear bomb in which a few kilograms of plutonium or uranium, ignited by a conventional explosive, would serve as a fission “trigger” to ignite a fusion explosion in a capsule containing several grams of deuterium-tritium. Does Russia have a neutron bomb? Hence, Moscow has […]
What role does groundwater play in the formation of caves?
What role does groundwater play in the formation of caves? Caves are one of the types of landforms created by groundwater erosion. Working slowly over many years, groundwater travels along small cracks. The water dissolves and carries away the solid rock. This gradually enlarges the cracks. Is responsible for the formation of subterranean caves? Solution […]
What are examples of perfectly inelastic collisions?
What are examples of perfectly inelastic collisions? Another common example of a perfectly inelastic collision is known as the “ballistic pendulum,” where you suspend an object such as a wooden block from a rope to be a target. What makes a collision perfectly inelastic? An inelastic collision is a collision in which there is a […]
Will Ball move by itself?
Is short wave AM or FM?
Is short wave AM or FM? Shortwave (SW) radio operates on the frequencies between the AM and FM bands. Shortwave has the unique characteristic of traveling very long distances making it a powerful medium to reach the masses from even one transmitter. Is WWV still broadcasting? In the ’70s, the WWV audio signal was made […]
Why do my legs sink when I try to float?
Why do my legs sink when I try to float? People with a high muscle-to-fat ratio tend to have dense legs, which resist floating horizontally. Because dense legs are less buoyant, they tend to sink, increasing drag. Practicing kicking drills to improve your kick will help you gain additional lift and propulsion to help counteract […]
What is the thickness of the foil?
What is the thickness of the foil? Standard household foil is typically 0.016 mm (0.63 mils) thick, and heavy duty household foil is typically 0.024 mm (0.94 mils). The foil is pliable, and can be readily bent or wrapped around objects. What is used for measuring the thickness of sheet? Some characterizations of thickness gauges […]
How long is a 20 Hz wavelength?
What is the major difference between descriptive and experimental research?
What is the major difference between descriptive and experimental research? Descriptive research refers to research which describes a phenomenon or else a group under study. Experimental research refers to research where the researcher manipulates the variable to come to an conclusion or finding. What is an example of a descriptive experiment? To experiment is defined […]
