Why does a dime flip over when air is blown across the top of the dime?
according to bernoulli's principle, when air is blown with an increased velocity over the dime, the air pressure beneath the dime decreases significantly and causes lift. this is the same principle with an airplane's wings. the shape of the wing causes the air on top of the wing to increase, causes a decrease in pressure beneath the wing. this causes lift.
Does a fluid's density change when it is compressed and attenuated?
Yes it does change because its mass does not change but its volume does. When it is compressed the density will increase because its volume does. When it is attenuated will decrease because the volume does. Density is mass over volume. Remember: it only works because its mass stays the same and the volume changes.
What is the increase of velocity over a period of time is?
Increase of velocity over a period of time is called acceleration.
How can you increase an object's gravitational potential energy?
By raising the object to a higher position. The potential energy also depends on the force of gravity, and on the object's mass, but for a given object (and for a given planet!), you have no control over these.
What is the mass of a foam ball?
Over 9,000
The movement of air mass over earth's surface causes?
It causes local weather changes.
If instead of the sun there was a black hole of the same mass in the center of the solar system would all the planets have the same orbits?
No. The sun is decreasing in mass (fusion) over time whereas a black hole would increase in mass over time (sucking up astroids, gas, etc). So over very long periods of time the sun's gravitational force will significantly decrease, and if it was a black hole it would increase. Increase/decrease in mass directly affects increase/decrease in gravitational force. Since gravitation (and motion) is what causes orbit, over long periods of times the planets would have very different orbits in the two scenarios (sun vs black hole).
Does the bowflex machine increase your muscle mass?
Yes, the bowfex machine increases your muscle mass. You can get buff and big in no time! Studies show that by using the bowfex machine you can increase you muscle mass over 30%!
Why alkali metal density increase going down the group?
Atomic-volume of alkali metals increases down the group ,But increase in mass dominates over increase in volume ,since density=(mass)/(volume) ,density increases down the group
What kind of air mass causes hot humid weather?
The kind of air mass that causes hot,humid weather are the air masses that form over places near the equator ! (Hope you have fun)
A blank is a large moving mass of land that over millions of years will 'drift' to a new location?
plant
What are the causes of over population in India?
industrialisationimmigrationimproved medicaltechniques leading to increase in birth rate and decrease in death rate.
What is the rise of an air mass caused by warming over land or sea that often causes the formation of clouds?
Convection!
How has the fertilizer industry developed?
fertilizer how became more advance the have been able to grow plant much faster , and increase the sizes of plants. a fertilizer is a plant grow with specific chemicals that promote plant grow , over the years more stable chemicals have been added to increase the growth strength....
Can a decrease in mass with an increase in volume result from the equation for density mass divided by volume?
Don't know what you are asking here. Mass is a innate property of matter you cant decrease mass. You can however increase volume (especially in gasses) so that the mas is spread out over a larger volume (usually by adding heat) and this DOES decrease the density. That is why hot air/water rises.
How can a volcano benefit the Earth's surface?
Volcanoes can increase land mass and over time produce very fertile land for growth.
What causes well water to over flow?
Some environmental agent as to increase the underground aquifer level. Maybe too much rain.
