What are the 5 points of particle theory? The five particle theory of matter All matter is made up of very small particles. All particles in a pure substance are the same. Different substances are made up of different particles. There is space between all particles. The particles are always moving. The particles in a […]

What is the impedance of RL circuit? Series RL Circuits Therefore, the two voltage drops (VR and VL ) are out of phase, based on the current I. When a sine wave is applied to an RL series circuit, the initial opposition to current flow is a series combination of R and X1. This total […]

Does higher entropy mean more stable? A system which is more disordered in space will tend to have more disorder in the way the energy is arranged as well. The entropy has increased in terms of the more random distribution of the energy. In essence . . . “a system becomes more stable when its […]

How do you say someone has a bright future? 2 Answers ‘has proven skills worth developing’ ‘could soon achieve excellence’ ‘deserves recognition for their achievements’ ‘has enviable proficiency’ ‘has risen admirably to recent challenges’ What does have a bright future ahead mean?

Where the exchange of oxygen and carbon dioxide takes place? Gas exchange takes place in the millions of alveoli in the lungs and the capillaries that envelop them. As shown below, inhaled oxygen moves from the alveoli to the blood in the capillaries, and carbon dioxide moves from the blood in the capillaries to the […]

Is L aspartic acid bad for you? Side Effects and Safety They found no safety concerns and concluded that this supplement is safe to consume for at least 90 days. On the other hand, another study found that two of 10 men taking D-aspartic acid reported irritability, headaches and nervousness. Should I take D aspartic […]

Why does a bicycle tire expand when filled with gas? You can observe a real-life application of Boyle’s Law when you fill your bike tires with air. When you pump air into a tire, the gas molecules inside the tire get compressed and packed closer together. This increases the pressure of the gas, and it […]

What gives a rainbow its shape? In raindrops, sunlight bounces back, or reflects, most strongly at a certain angle – 42 degrees. As long as the angle is right, then the light will be reflected and you see a rainbow. So the reflection gives you the shape of the rainbow, while the refraction gives you […]

What is the price of carbon nanotubes? The new method is capable of reducing the price of carbon nanotubes from $100 – $700 US to just $15 to $35 US for each gram, much lower than world market prices. The method known as the Continuous Production Method of Carbon Nanotubes using Rotation Reactor is the […]

How is apparent brightness calculated? Apparent brightness is thus measured in watts per square meter. For instance, the apparent brightness of the Sun is b = 1370 watts/meter2. That is, if you had a perfectly efficient solar panel one meter on a side, if you held it perpendicular to the Sun’s rays, it would generate […]
