Answer:
The force of gravity = GMm / r^2, where G is gravitational constant, M is mass of one object, m is mass of another object, r is distance between them.
To make gravity smaller, decrease mass or increase distance. To make gravity bigger, increase mass or decrease distance.
Answer 2
Answer:
You can increase the forces of gravity between you and, let's say, a planet, in two ways.
Way #1: Increase your mass. (Eat or drink more. Fill your pockets with rocks. Put on a heavy coat or space suit.)
Way #2: Get closer to the center of the planet. (That only works down to the planet's surface, but it stops working if you go below the surface.)
To decrease the forces of gravity, do exactly the opposite: -- lose weight -- get farther away from the object that gravity is attracting you to .
Also, don't forget: The forces of gravity always work both ways. The less the planet pulls on you, the less you pull on the planet. The harder the planet pulls on you, the harder you pull on the planet.
If a characteristic of a parent, such as eye color,does not show up in offspring ,is it gone forever
Answers
No it is not. It is still apart of the offspring's DNA. In fact it might show up in the very next generation!
How do ants use formic acid to stay alive

"When the crazy ants were dabbed with fire ant venom, they would go off and do this ... arid soils or severe freezes, that will be too harsh for them to survive.
Invasive “crazy ants” are rapidly displacing fire ants in areasacross the southeastern US by secreting a compound that neutralizes theother’s venom.It’s the first known example of an insect having the ability to detoxify another insect’s venom, researchers say.The crazy ant invasion is the latest in a series from the southernhemisphere and, like its predecessors, will likely have dramatic effectson the region’s ecosystems. Known for their painful stings on humansand other animals, fire ants dominate most ant species by dabbing themwith powerful, usually fatal venom. A topical insecticide, the venom istwo to three times as toxic as DDT on a per weight basis.invasive filesBut when a crazy ant is smeared with the venom, it begins anelaborate detoxification procedure—it secretes formic acid from aspecialized gland at the tip of its abdomen, transfers it to its mouth,and then smears it on its body.In lab experiments, exposed crazy ants that were allowed to detoxifythemselves had a 98 percent survival rate. This chemical counter-weaponmakes crazy ants nearly invincible in skirmishes with fire ants overfood resources and nesting sites. The research is published in thejournal science express.“As this plays out, unless something new and different happens, crazyants are going to displace fire ants from much of the southeastern USand become the new ecologically dominant invasive ant species,” says EdLeBrun, a research associate with the Texas invasive species researchprogram at the Brackenridge Field Laboratory at the University of Texasat Austin.Researchers have previously reported that where crazy ants take hold,the numbers and types of arthropods—insects, spiders, centipedes, andcrustaceans—decrease, which is likely to have a ripple effect onecosystems by reducing food sources for birds, reptiles, and otheranimals. They also nest in people’s homes and damage electricalequipment.
How do fossils provide evidence that evolution has taken place

What is the kinetic energy of a baseball moving at a speed of 40 m/s if the baseball has mass of 0.15 kg?
Answers
Kinetic Energy = 1/2 Mass (kg) * velocity squared (m/s)
KE = 1/2mV^2
KE = 1/2(0.15 kg)(40 m/s)^2
The answer is 120 joules.
0.5mv^2 > 0.5*0.15*40*40=120J
