A student is trying to lift a metal ball off the floor. The student is unable to lift the ball after several tries. Which of the following forces is most likely opposing lifting the ball?

possible answer: 1. Electric force
2. Frictional force
3. Gravitational force
4. Magnetic force

Answers

Answer 1

Answer:

i think it is three

Explanation:

it is a meatal ball soits going to be heavy and if it was 1 than his hands would be electricuted and its a meatal ball so if it is stationar than it should have no friction and if it had magnetic force aplied than it would be roling

The average speed of the blocks are 0.36 m/s.
Explanation:
Average speed is defined as the ratio of distance covered per unit time. So if it is said that blocks are pulled to 0.9 m in the right side. This means the blocks cover a distance of 0.9 m from the origin and that distance is covered in 2.5 s. Thus, the average speed can be calculated from the change in speed with respect to time. As at time t = 0 , the speed is also zero, and at time t = 2.5 s , the speed will be
Since, in this case, the speed is equal to the average speed of blocks. So the average speed of the blocks will be 0.36 m/s.
The answer is 0.36 m/s credit to the guy above me (give him Brainlyist) but I also had to do this assessment.

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.

Answers

Answer:

Because it is charged with the opposite type of energy to the wall.

The force that holds two atoms together is called a chemical bond.

What is a chemical bond

A chemical bond is a force of attraction that holds two or more atoms together to form a stable molecule or compound. Atoms consist of a positively charged nucleus containing protons and neutrons, surrounded by negatively charged electrons. In order to achieve a stable electronic configuration, atoms can undergo chemical bonding to fill their outermost electron shells.

Chemical bonds play a vital role in determining the physical and chemical properties of substances. The strength and type of bond between atoms influence factors such as boiling points, melting points, solubility, and reactivity. Understanding chemical bonds helps explain how different substances interact and form new compounds.

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.
