Answer:

b. The normal force between the molecules of the paper is overcome by the contact force of the hands.

Explanation:

The paper molecules are held together by a weak bond. When the student holds the paper on both sides with the center of the paper in between, the student applies two equal forces in the opposite direction of the paper making the paper molecules weaken and separate.

Answer:

The electrostatic forces from the contact of the hands with the paper causes the paper molecules to separate.

Here's the rest of the answers

1.) Which statement is correct about the strength of forces?

Electrostatic forces are trillions of times stronger than gravitational forces.

2.) A student tries to push a book across a table. Which forces acting on the book are a result of electrostatic forces?

normal force and friction

3.) What type of force can explain how a gecko climbs up a wall?

contact forces

5.) A heavy hammer is sitting on top of a board. Which statement correctly describes why the hammer does not go through the board?

The electrostatic forces between the molecules of the board prevent the force of gravity from breaking the board apart.

Decreases, stays the same, increases. The volume decreases because as air is cooled, the individual molecules collectively possess less kinetic energy and the distances between them decrease, thus leading to a decrease in the volume they occupy at a certain pressure (please note that my answer only holds under constant pressure; air, as a gas, doesn't actually have a definite volume). The mass stays the same because physical processes do not create or destroy matter. The law of conservation of mass is obeyed. You're only cooling the air, not adding more air molecules. The density decreases because as the volume decreases and mass stays the same, you have the same mass occupying a smaller volume. Density is mass divided by volume, so as mass is held constant and volume decreases, density increases.

9. A mouse has a mass of 0. 4kg. What is its weight? (acceleration due to gravity on Earth is 9.8m/s2 = g)
Alik [6]

Answer:

Weight = 3.92 N

Explanation:

Given:

Mass m = 0.4 kg

Acceleration due to gravity g = 9.8 m/s²

Find:

Weight

Computation:

Weight = Mass x Acceleration due to gravity

Weight = 0.4 x 9.8

Weight = 3.92 N
