Which best describes two counteracting forces on an object?
using a dolly to push a box to another location
two children pulling apart a wishbone
a group of dogs pulling a dogsled across ice
two people pushing a broken-down car up the road
Answer: B) two children pulling apart a wishbone
One person is on the left side, and the other person is on the right side. They pull in opposite directions to separate the bone. These forces counteract each other since they go in opposite directions.
In contrast, each of choice A, C, and D describe one or more forces that work together to go in the same direction. This could be a pulling force, or a pushing force, it doesn't matter either way. We can rule out choices A,C, and D for this reason.
Suppose you are shooting a basketball toward a hoop. As the ball rises in the air, its ---------------- energy increases and its ---------------------------- decreases.
Answer:
Suppose you are shooting a basketball toward a hoop. As the ball rises in the air, its -------Potential --------- energy increases and its -----------kinetic----------------- decreases.
Explanation:
Kinetic energy is the energy of movement or change. Potential energy is the energy a system has as a result of being able to undergo some change. ... As an object falls its potential energy decreases, while its kinetic energy increases. The decrease in potential energy is exactly equal to the increase in kinetic energy.

Which elements are metallic?
Iron.Uranium.Sodium.Aluminum.CalciumSilvery-white and light in weight, aluminum is a metal. It is supple and moldable. Cans, foil, culinary utensils, window frames, beer kegs, and airplane parts are just a few examples of the many goods that employ aluminum. This is as a result of its distinctive attributes.
Sodium is a soft metal that tarnishes when exposed to air in a matter of seconds. With water, it also reacts strongly. Sodium is employed as a reagent in the chemical industry and as a heat exchanger in some nuclear reactors. Salts of sodium, however, are more useful than the metal itself.
