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.

What can magnetic attraction and filtration both be used to do?
Separate compounds into their components.
Put components together to make a mixture.
Put components together to make a compound.
Separate mixtures into their components.
Answer:
C
Explanation:
makes sense
Answer:
Recycling centres use magnetic separation often to separate components from recycling, isolate metals, and purify ores. Overhead magnets, magnetic pulleys, and the magnetic drums were the methods used in the recycling industry. Magnetic separation is also useful in mining iron as it is attracted to a magnet.

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.

How can a charged balloon attract a wall without any contact?
The positive charges of the uncharged wall move to the outside.
The wall changes shape and the positive charges move to the inside.
The negatively charged balloon repels and moves away from the wall.
A positive charge in the balloon attracts the negative charges in the wall.
Answer:
Because it is charged with the opposite type of energy to the wall.
Answer: A
Explanation: The positive charges of the uncharged wall move to the outside.

Which event may occur when ocean salinity increases?
mass of water increases
freezing point of water increases
sunlight in deeper locations decreases
amount of dissolved gases in water increases
Salinity increases on increasing the mass of water.
What is salinity?
Salinity is the saltiness or amount of salt dissolved in a body of water.
When salt is dissolved in fresh water, the density of the water increases because the mass of the water increases. Therefore on increasing mass of water, salinity will increase.Adding salt to water lowers the freezing temperature. Thus salinity will decrease on increasing the freezing point of water.On decreasing the sunlight in deeper locations, salinity will also decrease.On increasing the amount of dissolved gases in water, salinity will decrease.Learn more:
