Is wattage important for hair dryer? Wattage does matter, but only to an extent: The amount of power put in, the more power you get out. While a high power or salon dryer uses more energy, that’s not necessarily the best form of measurement in terms of quality. A blow dryer may use high wattage […]

How do you calculate GPE? So to get the GPE of an object you need a formula, the formula is MASS X GRAVITY X HEIGHT (M X G X H). How does speed affect kinetic energy? It turns out that an object’s kinetic energy increases as the square of its speed. A car moving 40 […]

Can you fix female infertility? Infertility can be treated with medicine, surgery, artificial insemination, or assisted reproductive technology. Many times these treatments are combined. In most cases infertility is treated with drugs or surgery. What are reasons why a woman can’t get pregnant? Here are eight possible reasons you haven’t conceived yet. Not Trying Long […]

What makes an ecosystem successful? A healthy ecosystem consists of native plant and animal populations interacting in balance with each other and nonliving things (for example, water and rocks). Healthy ecosystems have an energy source, usually the sun. Decomposers break down dead plants and animals, returning vital nutrients to the soil. What are the two […]

How do you do scientific measurements? A measurement is obtained by comparing an object to some standard. Any observation is useful to a scientist, but quantitative observations are commonly considered more useful. Even if the measurement is an estimate, scientists usually make quantitative measurements in every experiment. What type of system do all scientist use […]

How do you determine the magnitude of a vector? The magnitude of a vector →PQ is the distance between the initial point P and the end point Q . In symbols the magnitude of →PQ is written as | →PQ | . If the coordinates of the initial point and the end point of a […]

How do you calculate the force between two wires? Section Summary The force between two parallel currents I1 and I2, separated by a distance r, has a magnitude per unit length given by. Fl=μ0I1I22πr F l = μ 0 I 1 I 2 2 π r . The force is attractive if the currents are […]
