Who has the shortest wavelength? gamma rays Is Hertz equal to m s? The SI unit for frequency is the hertz (Hz), which is equal to 1/s, or once per second. Frequency is encountered many times in physics. The phase speed of sound in air is 343 meters per second. What is the SI unit […]
Is water made of pee?
Is water made of pee? Urine is about 95% water. It is not completely sterile of microorganisms, as many sources incorrectly state. But it doesn’t contain any of the harmful microbes that can make you immediately sick—such as those you might ingest from contaminated wilderness water, and which are generally transferred through feces instead. Do […]
What was Clever Hans famous for?
What was Clever Hans famous for? Clever Hans, German der kluge Hans, a performing horse in Berlin in the late 19th and early 20th centuries celebrated for demonstrating remarkable intelligence. The feats performed by the horse were eventually explained as simple behavioral responses to subtle cues provided (perhaps unintentionally) by his handler. Which of the […]
What is the relationship between vapor pressure and temperature?
What is the relationship between vapor pressure and temperature? The vapor pressure of a liquid varies with its temperature, as the following graph shows for water. The line on the graph shows the boiling temperature for water. As the temperature of a liquid or solid increases its vapor pressure also increases. Conversely, vapor pressure decreases […]
What is the mass in grams of 9.86 x10 24 molecules of methanol?
What is the mass in grams of 9.86 x10 24 molecules of methanol? Therefore, the mass of methanol is approximately equal to 513.28 grams. What is the MR of methanol? 32.04 g/mol What is the difference between a 10% v/v methanol CH3OH solution and a 10% M M methanol solution? Unlock this answer 10%(v/v) is on […]
Do magnets get stronger when stacked?
Do magnets get stronger when stacked? Once a magnet is fully magnetised, it cannot be made any stronger as it is fully ‘saturated’. As more magnets are stacked together, the strength will increase until the length of the stack is equal to the diameter. After this point, any further magnets added will provide a negligible […]
What causes earthquakes in the middle of tectonic plates?
What causes earthquakes in the middle of tectonic plates? Earthquakes occurring away from tectonic plate boundaries can be triggered by the rise and fall of hot material through the Earth’s mantle, according to a new study. “The convection is caused in the mantle by internal heat production by decay of elements such as uranium and […]

What are the distinct characteristic of the Baroque period and its music?
What are the distinct characteristic of the Baroque period and its music? TIMBRE: Orchestral – strings, winds and harpsichord with very little percussion. DYNAMICS: Abrupt shifts from loud to soft – achieved by adding or subtracting instruments. An overall characteristic of Baroque Music is that a single musical piece tended to project a single mood […]
How many types of constraints are required to constrain a sketch?
How many types of constraints are required to constrain a sketch? two types What is a geometric constraint in CAD? Constraints are rules that are applied to 2D geometry. By applying constraints, you can control the location, size, distance, angle, and other parameters of objects in a drawing. There are two types of constraints: Geometric […]
