question 82

Multiple Choice

A turntable has a moment of inertia of 3.00 x 10^-2 kg*m² and spins freely on a frictionless bearing at 25.0 rev/min.A 0.300-kg ball of putty is dropped vertically on the turntable and sticks at a point 0.100 m from the center.By what factor does the angular momentum of the system change after the putty is dropped onto the turntable?

• A)1.22
• B)1.00 (no change)
• C)0.820
• D)1.50

Definitions:

Inhibitory Postsynaptic Potential

A type of synaptic potential that makes a post-synaptic neuron less likely to generate an action potential.

Excitatory Postsynaptic Potential

A temporary increase in postsynaptic membrane potential caused by the flow of positively charged ions into the postsynaptic cell.

Presynaptic Neuron

The neuron that sends a signal across a synapse to a target neuron during neurotransmission.

Action Potentials

Rapid electrical impulses that travel along the axon of a neuron, enabling nerve signal transmission.
