What is the perimeter of a sector? The formula for the perimeter of the sector of a circle is given below : Perimeter of sector = radius + radius + arc length. Perimeter of sector = 2 radius + arc length. What is sector area formula? The formula for sector area is simple – multiply […]
What happens if one of the cars collided with more force than the other one?
What happens if one of the cars collided with more force than the other one? Forces between two colliding objects It doesn’t matter if one car is heavier (more massive) than the other. The push force from one car will equal the push force from the other. What happens to the energy when two objects […]
What element has an electron configuration of 1s 2 2s 2 2p 5?
What element has an electron configuration of 1s 2 2s 2 2p 5? fluorine How do you figure out the electron configuration? To calculate an electron configuration, divide the periodic table into sections to represent the atomic orbitals, the regions where electrons are contained. Groups one and two are the s-block, three through 12 represent […]
Does frequency increase with tension?
Does frequency increase with tension? Increasing the tension increases the wave speed so the frequency increases. What is the fundamental frequency of the string? The lowest resonance frequency (n=1) is known as the fundamental frequency for the string. All the higher frequencies are known as harmonics – these are integer multiples of the fundamental frequency. […]
What happens if you remove one bulb in a series circuit?
What happens if you remove one bulb in a series circuit? In a series circuit, every device must function for the circuit to be complete. One bulb burning out in a series circuit breaks the circuit. In parallel circuits, each light has its own circuit, so all but one light could be burned out, and […]
What does a plastic stopper reduce?
What does a plastic stopper reduce? The vacuum prevents conduction. The tight stopper prevents air from entering or leaving the flask, so convection isn’t possible either. The sealed stopper stops heat getting in by convection; the vacuum stops conduction, and the metal lining between the outer case and the inner chamber stops heat radiating in […]
What are the two main types of steam turbines?
What are the two main types of steam turbines? Two types of steam turbines must be considered, condensing and noncondensing. What is the principle of steam turbine? In simple terms, a steam turbine works by using a heat source (gas, coal, nuclear, solar) to heat water to extremely high temperatures until it is converted into […]
How does the chemical industry work?
How does the chemical industry work? Industrial chemists work to develop and manufacture products and processes that will increase their company’s sales and profits. Products manufactured by the chemical industry fall into three categories: basic chemicals, specialty chemicals, and consumer chemicals. What are the uses of chemical industry? Who Are the Consumers of the Chemicals […]
Why do some states have straight borders?
Why do some states have straight borders? Why do many of USA’s states have straight borders? Because the borders were drawn up by invaders. The immigrants from Europe had no attachment to any particular area, so they just used straight lines to make it easier for them. Sometimes, they peacefully used rivers to divide the […]
What best describes how temperature humidity and pressure vary within an air mass?
What best describes how temperature humidity and pressure vary within an air mass? Temperature and humidity vary, but pressure does not. Temperature, humidity, and pressure are basically the same all through an air mass. Temperature at the border of an air mass is always higher than in the middle. Humidity makes the pressure in an […]
