question 124

Multiple Choice

Multiple-object systems without friction: A 6.00-kg block is in contact with a 4.00-kg block on a horizontal frictionless surface as shown in the figure.

• A) 6.00 N
• B) 20.0 N
• C) 8.00 N
• D) 4.00 N
• E) 10.0 N

Definitions:

Node of Ranvier

Gaps in the myelin sheath of nerve fibers where action potentials are generated, aiding in the rapid transmission of nerve impulses.

Dendrites

Extensions of neurons that receive signals from other neurons or sensory stimuli and convey them toward the cell body.

Chemical Synapse

A type of synapse at which a chemical (neurotransmitter) is released from the axon terminal of a neuron into the synaptic cleft between neurons, facilitating neural communication.

Synaptic Cleft

The tiny gap between two neurons, across which neurotransmitters travel to transmit nerve impulses.
