Ques: Q: What is the rotational equivalent of a force? Read this paragraph and choose the correct option from the provided answers: The magnitude, direction, and point of application of the force are incorporated into the definition of the physical quantity called torque. Torque is the rotational equivalent of a force. It is a measure of the effectiveness of a force in changing or accelerating a rotation (changing the angular velocity over a period of time). In equation form, the magnitude of torque is defined to be. Choices: - momentum - power - centripetal force - torque A:
Ans: torque

Ques: Q: What is the magnetic field traditionally referred to as? Read this paragraph and choose the correct option from the provided answers: 22.3 Magnetic Fields and Magnetic Field Lines Einstein is said to have been fascinated by a compass as a child, perhaps musing on how the needle felt a force without direct physical contact. His ability to think deeply and clearly about action at a distance, particularly for gravitational, electric, and magnetic forces, later enabled him to create his revolutionary theory of relativity. Since magnetic forces act at a distance, we define a magnetic field to represent magnetic forces. The pictorial representation of magnetic field lines is very useful in visualizing the strength and direction of the magnetic field. As shown in Figure 22.15, the direction of magnetic field lines is defined to be the direction in which the north end of a compass needle points. The magnetic field is traditionally called the Bfield. Choices: - m-field - charged field - spicule - bfield A:
Ans: bfield

Ques: Q: Matter is always conserved in what type of reaction? Read this paragraph and choose the correct option from the provided answers: In a chemical reaction, the quantity of each element does not change; there is the same amount of each element in the products as there was in the reactants. This is because matter is always conserved. The conservation of matter is reflected in a reaction's chemical equation. The same number of atoms of each element appears on each side of the arrow. For example, in the chemical equation above, there are four hydrogen atoms on each side of the arrow. Can you find all four of them on each side of this equation?. Choices: - developed reaction - Quick reaction - toxic reaction - chemical reaction A:
Ans: chemical reaction

Ques: Q: The extracellular fluid is in contact with the axon membrane only at what location? Read this paragraph and choose the correct option from the provided answers: Choices: - dendrites - synapses - Sensory Receptors - the nodes A:
Ans:
the nodes
