Does gravity increase or decrease when the distance increases between two objects?
Gravity decrease as you get farther, and every mass has gravitational pull.
Does the gravitational force decrease as distance between two objects increase?
Yes it does.
Does the increase between two objects increase or decrease the gravitational force between them?
At a greater distance, the gravitational force becomes less.
Why would magnetic declaration be different for different locations on the earth?
First of all, we're pretty sure that you're referring to "variation", not "declaration".Magnetic variation is the difference between the direction from you to the north pole (called "true north"), and the direction in which your magnetic compass points.That difference changes with your position on earth, because the north pole and theplace your compass points to are two different places. If you were standing at the point that's exactly halfway between them, then your compass would point exactly away from the north pole. And if you're not between them, but you're standing on the extension of the line between them, then your compass it pointing at the north pole, because both points are in the same direction from you.If you look at a navigational map, you will see lines of magnetic variation printed on the map. If you read your magnetic compass and apply the magnetic variation (printed on the map), you can calculate the direction of TRUE north.
What happens to the gravitational force between two objects if the mass of one of the objects is decreased?
The gravitational forces between two objects are proportional to the productof the two masses. So if either mass decreases and the distance between theobjects doesn't change then the gravitational forces between them also decrease.
Why do populations of asexually reproduced organisms show little variation?
There is no natural selection and therefore no evolutionary need for a difference between genders.
What is the relationship between two quantities that increase or decrease together?
Direct variation
The relationship between two quantites that increase or decrease together is called?
Variation in direct proportion.
What living thing has an evolutionary link between Dinosaurs?
Birds have an evolutionary link between Dinosaurs...
What is the difference between variety and variation?
What is the difference between variation and variety
What is interspecific and intraspecific cooperation?
Interspecific cooperation refers to help or assistance of individuals belonging to different species (a case of this is mutualism), whereas intraspecific cooperation is observed between individuals within the same species
What is the difference between variation order and extra work in construction?
A variation order is when there is a decrease or increase in quantities in your original scope of work. While an extra work is a new item of work introduced which shall be added into your original scope and will be binded in your contract.
What is so important about genetics?
The contributions of modern genetics to the understanding of evolution have been threefold. First, it has documented the extent of genetic variation that exists in populations as a basis for future evolution. In particular it has shown that natural selection has not destroyed all variation, as might be predicted, so that there must be mechanisms for the maintenanceand origin of new selectable variation that balance the homogenizing forces of selection. Second, it has begun to provide a mechanism of the origin of genetic novelties which must be at the basis of the major features of the history of life. In doing so, it has shown how selection fornew features is at all times historically contingent and that evolution is at all times at riskof falling into genetic dead-ends. Third, modern genetics has greatly enriched the diversity ofmechanisms known to cause evolutionary change. All of these mechanisms involve the conversion of variation between individuals into variation between populations in time and space, but many are non-selective or even counter-selective. Natural selection is not the only mechanism of evolution.
Is direct variation a function?
A direct variation is a situation in which two quantities -- such as hours and pay, or distance and time -- increase or decrease at the same rate. The ratio between the quantities is constant; that is, as one quantity doubles, the other quantity also doubles. so yes it is. -add on- A direct variation is in the form y=ax where a is an constant.
What is the difference between wild populations and natural populations?
nothing
How is cladistics used to reveal evolutionary relationships between organisms?
Cladistics is a method of analyzing the evolutionary relationships between groups to construct their family tree.
In testing for differences between the means of two related populations the null hypothesis is?
That there is no difference between the means for the two populations.
