Why do planes fly over water instead of land? At lower levels, being over sea would typically offer less turbulence, in part because as the ground warms you can encounter rising air thermals. Generally, airliners fly whatever route provides the shortest time, which is not always the shortest distance, often called the Great Circle route. […]
What are the possible sources of error in a bomb calorimetry experiment?
What are the possible sources of error in a bomb calorimetry experiment? Sources of error include the percent error in water measurement and incomplete vaporization of the nichrome wire. The internal volume of the Parr-bomb was measured to be 341mL. Why is benzoic acid used to calibrate a bomb calorimeter? Benzoic acid (C6H5CO2H) is often […]
How do muscles get oxygen?
How do muscles get oxygen? Oxygen is supplied to the muscles via red blood cells. Red blood cells carry hemoglobin which oxygen bonds with as the hemoglobin rich blood cells pass through the blood vessels of the lungs. The now oxygen rich blood cells carry that oxygen to the cells that are demanding it, in […]
What is the effect of unbalanced forces?
What is the effect of unbalanced forces? An unbalanced force can change an object’s motion. An unbalanced force acting on a still object could make the object start moving. An unbalanced force acting on a moving object could make the object change direction, change speed, or stop moving. What would the resultant force on an […]
Why autonomous systems are important?
Why autonomous systems are important? Advantages of autonomous systems are their ability to go into places and situations where humans cannot. This includes dangerous places, such inspecting inside nuclear reactors to check for faults, and inaccessible places, such as inside aero-engines. What does autonomous mean? 1a : having the right or power of self-government an […]
Is it bad to be emotionally dependent?
Is it bad to be emotionally dependent? Though emotional dependence stems from a lack of self-esteem, it’s also a self-esteem destroyer of its own, undermining our confidence subtly and over time. When we become too dependent emotionally on our spouse or partner, we run the risk of losing the person that we love by losing […]
What is a good question to ask about space?
What is the potential energy at the top of the hill?
What is the potential energy at the top of the hill? The amount of potential energy is dependent upon mass and height and is found using the equation PE=m*g*h where g is the acceleration of gravity (approximated here to be 10 m/s/s). For a 50-kg sledder on top of a 4.0-meter high hill, the potential […]
Which 5 SI units are commonly used in chemistry?
Which 5 SI units are commonly used in chemistry? The five SI base units commonly used by chemists are the meter, the kilogram, the kelvin, the second, and the mole. What metric units are commonly used to measure length, volume, mass, temperature and energy? In SI, the basic unit of length is the meter (m). […]
