What does 10 C mean the temperature is? Celsius vs. Fahrenheit Temperature oC oF 10 50 15 59 20 68 At what temperature are Kelvin and Celsius the same? Celsius and Fahrenheit are the same at – 40 degrees since the scales converge. Celsius and Kelvins become equal at high temperatures as the difference of […]

Is salt water more dense than sugar water? Here’s why: Salt is about 25% more dense than sugar. Therefore a teaspoon of salt weighs more than a teaspoon of sugar by almost 25%. Why is salt water denser than sugar water? When salt is dissolved in water, as it is in ocean water, that dissolved […]

What is particle in physics class 11? It is a branch of physics that studies the basic elements of matter and radiation and the interaction between them. The word particle can refer to various types of very small objects, but this branch usually investigates the irreducibly smallest detectable particles. What is particle mean? 1a : […]

What are the two plates at the major plate boundary of the most seismically active area of North America? Specifically, the San Andreas fault zone separates the Pacific and North American Plates, which are slowly grinding past each other in a roughly north-south direction. Is North America moving away from Europe? The North American and […]

Where is the highest probability of locating an electron in 1s orbital? The 1s orbital is spherically symmetrical, so the probability of finding a 1s electron at any given point depends only on its distance from the nucleus. The probability density is greatest at r = 0 (at the nucleus) and decreases steadily with increasing […]

Is mol dm 3 the same as M? In chemistry, the concentration is usually expressed in moles per dm3. This is often shortened to M, so a solution with a concentration of 0.01 moles per dm3 can be written as 0.01 M. A solution that contains 1 mole of solute per dm3 is often called […]

What are examples of theory? The definition of a theory is an idea to explain something, or a set of guiding principles. Einstein’s ideas about relativity are an example of the theory of relativity. The scientific principles of evolution that are used to explain human life are an example of the theory of evolution. How […]

Why did Rutherford use gold foil instead of magnesium foil? Rutherford used gold for his scattering experiment because gold is the most malleable metal and he wanted the thinnest layer as possible. The gold sheet used was around 1000 atoms thick. Therefore, Rutherford selected a Gold foil in his alpha scatttering experiment. Why did Rutherford […]

How does a single movable pulley works? The wheel of a moveable pulley is not attached to any stationary object; one end of the rope is stationary instead. In a moveable pulley, the weight is attached to the wheel rather than the rope, and the wheel moves along the length of the rope as the […]
