Does a water pump push or pull? Depending on the pump design it can push, pull or do both. In reality, all pumps are pushers, since even a pulling pump (e.g., sucking water up a drinking straw) is simply removing pressure on the pump side so that greater pressure on the pumped fluid at the […]

Why Nitrogen is not a greenhouse gas? Oxygen and nitrogen are not greenhouse gases, because they are transparent to infrared light. These molecules are invisible because when you stretch one, it doesn’t change the electric field. In general, symmetrical molecules with only two atoms are not greenhouse gases. Why is sulfur dioxide not a greenhouse […]

What is the most densest element? element osmium What is the lightest natural metal? magnesium What are the 3 lightest metals? The first seven metals in the periodic table are lithium, beryllium, sodium, magnesium, aluminium, potassium and calcium, known collectively as the “lightest metals”. What is the lightest thing in the world? Graphene Aerogel What […]

What is the final velocity of the two vehicle mass? A 1500 kg car traveling at 15 m/s to the south collides with a 4500 kg truck that is intially at rest at a spotlight. The car and the truck stick together and move together after the collison. Therefore, the final velocity of the two-vehicle […]

How deep is the Florida Platform? approximately 1,800 meters deep How deep is the sand in Florida? about 3 to 4 feet Is there a pink sand beach in Florida? Pink Sands Beach has about three miles of shoreline. The water is a bright turquoise blue with gentle waves thanks to the surrounding coral reefs. […]

What is a step down transformer for voltage? A Step down Transformer is a type of transformer, which converts a high voltage at the primary side to a low voltage at the secondary side. If we speak in terms of the coil windings, the primary winding of a Step down Transformer has more turns than […]

When two or more systems are in thermal equilibrium with each other they will have the same temperature? In other words, if two objects are in thermal equilibrium, they have the same temperature. If thermometer A is in thermal equilibrium with object B, and B is in thermal equilibrium with C, then A is in […]

What is time period of a simple pendulum? The time period of a simple pendulum: It is defined as the time taken by the pendulum to finish one full oscillation and is denoted by “T”. Length of a simple pendulum: It is defined as the distance between the point of suspension to the centre of […]

What is the common ratio for this geometric sequence 4 24 144? = 6 (answer). What is the formula of common difference? The common difference is the value between each number in an arithmetic sequence. Therefore, you can say that the formula to find the common difference of an arithmetic sequence is: d = a(n) […]

What is a scientific principle examples? If you drop an apple, it will fall. If you throw an apple in the air, it will follow a specific path while falling down. Newton’s laws don’t tell us why the apple falls or what causes it to fall, just that it does fall. Similarly, the law of […]
