Where does the US get its cobalt? Approximately 10 percent of U.S. cobalt imports are from Finland and about 20 percent from Norway. Cobalt imports into the United States totaled about 10,000 metric tons in 2020. Exports accounted for about 3,500 metric tons in the same year. The largest cobalt deposits are found in 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 […]
How do you find the amplitude of a sound wave?
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 […]
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 […]
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 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 […]
What are the components of centripetal force?
What are the components of centripetal force? As a bucket of water is tied to a string and spun in a circle, the tension force acting upon the bucket provides the centripetal force required for circular motion. As the moon orbits the Earth, the force of gravity acting upon the moon provides the centripetal force […]
