What object has the greatest force of gravity? On the planet Jupiter, where gravity is stronger, you would weigh much more than you do here. On the sun, gravity is so strong that you would weigh about 27 times as much as on earth! What is the most cheapest thing in the universe? The answer […]
What gives a rainbow its shape?
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 […]
Which cell has highest efficiency?
Which cell has highest efficiency? Scientists have developed a solar cell that is capable of converting direct sunlight into electricity with 44.5 percent efficiency — making it, potentially, the most efficient solar cell in the world. Current solar technology only converts electricity with a maximum efficiency of about 25 percent. Which metal is used to […]
How can you tell if a precipitate has formed in solution?
How can you tell if a precipitate has formed in solution? The identity of the precipitate can often be determined by examining solubility rules. It also occurs in single displacement when one metal ion in solution is replaced by another metal ion. Notice the new solid forming on the bottom of the tube. Which solution […]
What is difference between igneous and sedimentary rocks?
What is difference between igneous and sedimentary rocks? There are three kinds of rock: igneous, sedimentary, and metamorphic. Igneous rocks form when molten rock (magma or lava) cools and solidifies. Sedimentary rocks originate when particles settle out of water or air, or by precipitation of minerals from water. They accumulate in layers. What are the […]

What are the 4 types of parking?
What are the 4 types of parking? Types of Parking: Angle Parking: In this type of parking, cars are parked at an angle. Perpendicular Parking: This type of parking is common in parking lots, where people park their cars for a longer duration. Parallel Parking: Illegal Parking: Lot Parking: Bay Parking: Between two Vehicles: What […]
What are examples of alternative energy?
What are examples of alternative energy? The Best Examples of Alternative Energy Sources Solar Power. When most people think of alternative energy sources they tend to use solar power as an example. Nuclear Power. Hydroelectric Energy. Wave Energy. Biofuels. Natural Gas. Geothermal Power. Wind Energy. What is the three basic energy system? During exercise, your […]
Which gas is highly compressible?
Which gas is highly compressible? Gases are compressible because most of the volume of a gas is composed of the large amounts of empty space between the gas particles. At room temperature and standard pressure, the average distance between gas molecules is about ten times the diameter of the molecules themselves. How much work is […]
