What happens to momentum when two billiard balls collide? This is because Newtons third law of motion states that forces are equal in size and opposite in direction- so when the balls collide, the momentum of the first ball is lost and is gained by the second ball and the total momentum of the two […]

How much does it cost to drive 300 miles? Cost To Drive 300 Miles MPG $2 per gallon $3 per gallon 3 MPG $200.00 $300.00 4 MPG $150.00 $225.00 5 MPG $120.00 $180.00 6 MPG $100.00 $150.00 How much does it cost me per mile to drive my car? After factoring in the costs of […]

What is an example of minimum wage? For example, a minimum wage of $10 per hour will not affect workers whose marginal productivity in a given line of work is greater than $10 per hour. The legal supply and demand rate remains unchanged for such labor. What was the original minimum wage? $0.25 per hour […]

When a skier skis down a hill? The correct answer is “c”: the normal force exerted on the skier by the hill is less than the weight of the skier. What forces act on a skier? Gravity, friction and the reaction forces from the snow. These are forces that act upon a skier. A skier […]

Can a cheetah kill a leopard? Can a cheetah kill a leopard? A cheetah could kill and eat a leopard cub, but comparing like for like – a female leopard vs a female cheetah or a male leopard vs a male cheetah – the leopard’s greater weight and power would ensure that they won any […]

What is the earth water layer called? Hydrosphere Which layer of the Earth is the hottest? inner core Is there an ocean deep inside the Earth? The finding, published in Science, suggests that a reservoir of water is hidden in the Earth’s mantle, more than 400 miles below the surface. It extends deep into the […]

Is humidity good or bad for sinuses? When the air you breathe is too dry, the mucus in your nose and sinuses won’t flow properly and your sinuses won’t drain as well as they should. Congestion can then lead to sinus pain and sinusitis. Sinusitis experts agree that adding humidity to the air with a […]

Can we create protons? One can obtain a proton by stripping an electron from a hydrogen atom because hydrogen consists of one proton and one electron. This is known as ionization. At Fermilab, we take hydrogen and add an extra electron. This results in negative hydrogen ions. Do protons die? To the best of our […]

Where is Huffman coding used? Huffman coding is a method of data compression that is independent of the data type, that is, the data could represent an image, audio or spreadsheet. This compression scheme is used in JPEG and MPEG-2. What are the steps of Huffman coding? Huffman coding is done with the help of […]
