Does gravity affect density's properties For example if there was no gravity would objects that typically sink in water not?
Gravity may cause the density of a medium to vary with depth. For example because we have gravity the pressure in water is much higher 1 kilometer below the surface than just 1 meter. This is because the water at 1 kilometer down also has to carry the water above it. If there was no gravity water would not fall down, and as such there would be no pressure (and thus no density difference). Without gravity objects would not sink. Think of it this way; the only thing that separates up from down in water is that gravity pulls things down. If it was not present up and down would be equal, so you expect the object to respect that and just remain where it is. By the way, liquid only varies very slightly with increased pressure.
The Relative Surface Gravity on Earth is what?
The question doesn't include enough information to make an answer possible.Whenever you talk "relative", you then must specify: relative to what.The weight of an object on the Earth's surface is much smaller than the sameobject's weight on the sun's surface, but much larger than its weight on thesurface of a bowling ball.
Why is the earth gravity stronger than the moon gravity?
Gravity is a force created by and felt by mass. All massive objects have a force of gravity that is directly proportional to the amount of mass within the object. The gravitational constant is a coefficient that relates exactly how much mass = how much gravity. Given that the moon is less massive than the Earth, we would expect less gravity. Similarly, Jupiter has much more mass than the Earth and also has more gravity.
What do you expect the value of the acceleration of gravity to be?
9.81
Is gravity on earth greater or less then gravity on Venus?
The gravity present on a planet is usually denoted by the acceleration an object would experience due to gravity on that planet's surface. If we stick to Newtonian gravity (which should be adequate for our present purpose) the acceleration due to gravity on a planet is given by: a = G*M / R^2 Where G is Newton's gravitational constant, M is the mass of the planet, and R is its radius (remember we are standing on the surface). (Note: Here I have neglected the vector qualities of acceleration, this will not matter at present, the acceleration will be pointing down, towards the center of the planet.) From this formula we can see that the acceleration increases if the mass of the planet increases. This is to be expected; gravity (in Newtonian gravity) is caused by mass, and thus a bigger mass means a stronger gravitational field. Since Venus is less massive than Earth we might expect the surface gravity on Venus to be less than on Earth. However, we also have the R^2 in the denominator. This means the surface gravity on a planet will increase if the radius decreases (and the mass stays the same). This is also clear; if the radius is less then you stand deeper into the gravitational field. Venus is about the same size as Earth so this effect should not play as much a role as the difference in mass does. Thus, just by using these arguments we can already conclude that the surface gravity on Earth is larger than the surface gravity on Venus. Let us now look at some numbers. Earth's surface gravity is about 9.81 m/s^2 (it varies slightly from location to location). And Venus' surface gravity is 8.87 m/s^2, which is less, as expected. This means that if you weigh 70 kg on Earth you will weigh 70*(8.87/9.81) = ~63 kg on Venus.
Why does not the moon have gravity?
The moon does have gravity but it is much weaker it hase 1/6 of the earths gravity. wihout it how do you expect the men on the moon to stay on the moon?
How would you expect leaves and stems to grow in response to gravity?
Stems will always grow towards light and away from gravity.
Which substance in each of the following pairs would you expect to have larger dispersion forces?
The substance with a larger molecular mass will generally have larger dispersion forces. Additionally, molecules with more surface area tend to have stronger dispersion forces.
What do you expect to see if the liquid surface tension is less than or equal to the critical surface tension of a surface?
If the liquid surface tension is less than or equal to the critical surface tension of a surface, you would expect the liquid to spread out and wet the surface. This is because the liquid will be able to overcome the cohesive forces holding it together and adhere to the surface.
Which planet has the lowest gravity at its surface?
Mars, bizarrely...The mean surface gravity of a planet is determined primarily by its mass and its radius. Prior to the reclassification of the major bodies in our solar system, the smallest planet by volume and mass was Pluto. Pluto has a mean surface gravity of 0.062 Earth equivalents.However, Pluto has been reclassified as a dwarf planet.This demotes the planet Mercury into last place in terms of volume and mass. You might expect, therefore, Mercury to have the lowest surface gravity of the eight major planets. However, the planet Mars, despite having about twice the mass of Mercury, has a radius about 1000 km larger. So, actually Mars has a fractionally lower mean surface gravity.Mercury = 0.3772 Earth equivalentsMars = 0.3769 Earth equivalents(measured at the equator).For "surface gravity", the mass of a planet is effectively concentrated at the center (the center of mass). So, the gravitational force is less when the surface is further from the center of mass.So, a planet's surface gravity increases with its mass, but reduces with its radius.One of the small contributory factors to this reversal in expected ranking may be due to the comparatively slow rotation of Mercury (58.6 Earth days per rotation with an average speed of 10.9 km/h. Compare Mars: 1.03 Earth days and 868 km/h).The small rotational speed on Mercury means the outward acting centrifugal effect, which opposes the inward pull of gravity, is small.(Strictly speaking this only matters when we are talking about what scientists call "apparent surface gravity".)
Does the value of accelaration due to gravity increases in winter?
No. There's no reason to expect that to happen.
Which latitudes would you expect to find high surface pressures?
You can expect to find high surface pressures at the poles because they have all of the cold air sinking down to the surface due to the low intensity of insolation on the poles.
