How do you find the velocity of two vectors? Start with this equation: vf = vo + a x t. Convert the original velocity into vector component notation: (10.0, 0) meters/second. Convert the acceleration into components. Use the equation ay = a sin theta to find the y coordinate of the acceleration: 15 x sin […]
Can you build muscle in space?
Can you build muscle in space? Due to the lack of gravity in space, astronauts experience a decrease in muscle mass and bone density. That same mass can take up to four years to build back up on Earth. To fight against this deterioration, astronauts have a very vigorous exercise regimen in space. How do […]

What […]
Are there any Saturn V rockets left?
Are there any Saturn V rockets left? Nine Saturn V rockets moved astronauts to the moon between 1969 and 1972, but there were three extras made — and you can still see some of the pieces today, a retired Boeing engineer says. Is Falcon Heavy more powerful than Saturn V? The private space company says […]
What is high melting point?
What is high melting point? A high melting point results from a high heat of fusion, a low entropy of fusion, or a combination of both. In highly symmetrical molecules the crystal phase is densely packed with many efficient intermolecular interactions resulting in a higher enthalpy change on melting. Is melting of ice? Fresh water […]
What are the three ways of heat transfer in engines?
What are the three ways of heat transfer in engines? 3, ICE Heat transfer and wall temperature modelling are reviewed and classified in three main heat transfer phenomena: gas to wall(convection and radiation problems), wall to wall(conduction and contact resistance problems) and wall to liquid(convection problems) values. How heat is removed from the engine? There […]
Is Wind chill the actual temperature?
Is Wind chill the actual temperature? Your wind-chill temperature is the intersection of your actual temperature and the wind speed. For example, if your actual temperature is 20 degrees Fahrenheit and the wind speed is 25 mph, then the wind-chill temperature is -14 degrees Fahrenheit (see chart below). In such a case, stay inside and […]
