What is centripetal force equal to? The magnitude F of the centripetal force is equal to the mass m of the body times its velocity squared v 2 divided by the radius r of its path: F=mv2/r. According to Newton’s third law of motion, for every action there is an equal and opposite reaction. Why […]

Why is Greek pottery orange and black?
Why is Greek pottery orange and black? The bright colours and deep blacks of Attic red- and black-figure vases were achieved through a process in which the atmosphere inside the kiln went through a cycle of oxidizing, reducing, and reoxidizing. During the oxidizing phase, the ferric oxide inside the Attic clay achieves a bright red-to-orange […]
What are the types of systematic errors?
What are the types of systematic errors? Systematic errors may be of four kinds: Instrumental. For example, a poorly calibrated instrument such as a thermometer that reads 102 oC when immersed in boiling water and 2 oC when immersed in ice water at atmospheric pressure. Observational. For example, parallax in reading a meter scale. Environmental. […]
What are the 3 laws of charges?
What are the 3 laws of charges? Based on the same types of experiments like the one you performed, scientists were able to establish three laws of electrical charges: Opposite charges attract each other. Like charges repel each other. Charged objects attract neutral objects. What are the basic laws of electricity? The Fundamental Laws of […]
Does conductivity depend on amount of material?
Does conductivity depend on amount of material? Conductance and resistance vary corresponding to the size of the material in question, while conductivity and resistivity do not. Does conductivity depend on mass? In this case the thermal conductivity depends on the mass, and that is the reason that helium and hydrogen have very high thermal conductivity. […]

Is there a black star?
Is there a black star? A black star is a gravitational object composed of matter. It is a theoretical alternative to the black hole concept from general relativity. The theoretical construct was created through the use of semiclassical gravity theory. It will appear almost exactly like a black hole. What does a black star stand […]
What four factors help a solute dissolve?
What four factors help a solute dissolve? A: The rate of dissolving is influenced by several factors, including stirring, temperature of solvent, and size of solute particles. Can a solute be removed from a solvent? Because a solute is completely dissolved in its solvent, the two cannot be separated by simply pouring away the solvent […]
