Can you see geostationary satellites? Unlike the ISS and the many objects in low Earth object, geostationary satellites are visible all night long every night of the year. They only disappear for up to 70 minutes a day when entering Earth’s shadow about two weeks either side of each equinox. What is the difference between […]

How does the force of gravitation between two objects change when the distance between them is reduced to half Class 9 Ncert? How does the force of gravitation between two objects change when the distance between them is reduced to half? Ans. The force of gravitation between two objects is inversely proportional to the square […]

What ABS system uses a separate wheel speed sensor for each wheel? The most efficient ABS brake system is the four-channel, four-wheel system. This system has a speed sensor and hydraulic circuit dedicated to each wheel. The module controls each wheel during a skid situation. How many channels are in the 4 ABS sensor? The […]

What is an example of chemical weathering by water? Chemical Weathering From Water Chemical weathering occurs when water dissolves minerals in a rock, producing new compounds. This reaction is called hydrolysis. Hydrolysis occurs, for example, when water comes in contact with granite. Feldspar crystals inside the granite react chemically, forming clay minerals. What are the […]

Can I put my hand through a wall? You could move an object through a wall without having enough energy to embed it inside a wall. But you can’t do that with just your hand, since your arm would have to be in the wall. Also, while it does get to the other side of […]

How fast is a Thermapen? The Thermapen Is the Last Cooking Thermometer You’ll Ever Need. “It takes readings in less than three seconds, is accurate to less than a degree, and is designed to last for ages. What kind of heat transfer occurs mostly on the earth’s surface? Energy is transferred between the Earth’s surface […]

Does a solar water heater work at night? Since solar water heaters require the sun to heat water, you may be wondering if they can provide you hot water at night. Since solar water heaters require the sun to heat water, you may be wondering if they can provide you hot water at night. The […]

Are viruses alive Usatestprep answers? Once again, the scientific view changed: viruses may be complex biochemical particles but they are not alive. Viruses depend on the host cell for the raw materials and energy necessary for nucleic acid and protein synthesis, as well as all other biochemical activities that allow the virus to multiply and […]

Is there a relationship between mass and speed and computing kinetic energy Why? An object with less speed and more mass could potentially have the same Kinetic energy. The equation for Kinetic Energy is: KE = 1/2 mv2. Kinetic energy has a direct relationship with mass, meaning that as mass increases so does the Kinetic […]

What are 3 uses for lanthanum? Lanthanum and other rare-earth compounds are used in carbon arc lighting, specifically in the film and television industry for studio lighting and projection. Lanthanum oxide (La2O3), also called lanthana, improves the alkali resistance of glass and is used in making camera lenses and in other special glasses. Is scandium […]
