The question asks to identify examples where applying force changes an object's shape. We need to evaluate each given option to see if it demonstrates this principle.
D) All the above — As analyzed, all the given examples (rolling dough, pressing a rubber ball, and molding clay) involve applying force to change the shape of the respective objects. Therefore, 'All the above' is the correct choice.
The question asks to identify the incorrect statement among the given options regarding the four fundamental forces of nature: gravity, electromagnetism, weak nuclear force, and strong nuclear force. We need to evaluate each statement based on the known properties of these forces.
A) Gravity is the strongest of the four. This statement is incorrect because gravity is actually the weakest of the four fundamental forces.
The question asks to identify the type of force exerted by the Earth to pull objects towards itself. This is a fundamental concept in physics related to forces and their classifications.
C) Gravitational force is the force by which the Earth (or any body with mass) attracts other objects towards its center. It is a non-contact force.
The question asks for the SI unit of force. We need to recall the standard units for various physical quantities in the International System of Units (SI).
B) Newton is the SI unit of force. One Newton is defined as the amount of force required to accelerate a mass of one kilogram at a rate of one meter per second squared.
The question asks about the effects of force on a body. We need to recall the definition of force and its various manifestations in physics.
Correct Option: D) All the above
Since options A, B, and C are all valid effects of force, the most comprehensive correct answer is D.
The question asks to identify a contact force from the given options. We need to understand the definition of contact and non-contact forces to answer this question.
D) Friction — Friction is a force that opposes motion or tendency of motion between two surfaces that are in direct physical contact. Without contact, there can be no friction.
