What are the 3 types of reflecting telescopes?
What are the 3 types of reflecting telescopes? This lesson will discuss three major kinds of traditional reflecting telescopes and their major differences. These include the Newtonian, Cassegrain, and Schmidt-Cassegrain telescopes. What does a star diagonal do? A star diagonal, erecting lens or diagonal mirror is an angled mirror or prism used in telescopes that […]
What are the two main properties of a sound?
What are the two main properties of a sound? The two main properties of sound are frequency and amplitude. The frequency of the sound waves determines the pitch of the sound. The amplitude of sound determines the loudness. The quality of sound is affected by the pitch and the loudness. What are the three main […]
What is missing from the push pull explanation of immigration?
What is missing from the push pull explanation of immigration? Push” factors are conditions in migrants’ home countries that make it difficult or even impossible to live there, while “pull” factors are circumstances in the destination country that make it a more attractive place to live than their home countries.[1] Common “push” factors include violence, […]
How do you make an electric motor more powerful?
At what temperature water has highest density?
At what temperature water has highest density? At 39°F (or 3.98°C to be exact) water is the most dense. This is because the molecules are closest together at this temperature. The closer the molecules, the heavier. The farther apart the molecules, the lighter. At what Celsius does water reach its greatest density? four degrees Celsius […]
At what position is the kinetic energy equal to the potential energy?
At what position is the kinetic energy equal to the potential energy? When the kinetic energy is maximum, the potential energy is zero. This occurs when the velocity is maximum and the mass is at the equilibrium position. The potential energy is maximum when the speed is zero. Where does the pendulum have an equal […]
What is hotter sun or lava?
What is hotter sun or lava? But even lava can’t hold a candle to the sun! At its surface (called the “photosphere”), the sun’s temperature is a whopping 10,000° F! That’s about five times hotter than the hottest lava on Earth. A temperature of 27 million degrees Fahrenheit is more than 12,000 times hotter than […]
Can you hit a piece of tissue in mid air with the same amount of force that you can hit a heavy bag?
Is it possible to have no water in the air?
Is it possible to have no water in the air? There will always be some water vapor in the air unless there is no free water on the surface of the planet. We have air with 0.000% water vapor. Living creatures exhale and plants photosynthesize while this is going on. These actions, not surprisingly, place […]
