Two Masses Are Connected by a String Which Passes Over

question 128

Multiple Choice

Two masses are connected by a string which passes over a pulley with negligible mass and friction. One mass hangs vertically and one mass slides on a 30.0 degree incline. The inclined surface has a coefficient of kinetic friction of 0.200. The vertically hanging mass is 6.00 kg and the mass on the incline is 4.00 kg. The magnitude of the acceleration of the 4.00 kg mass is (the initial velocity of the 4.00 kg mass is down the incline)

• A) 7.16 m/s².
• B) 5.84 m/s².
• C) 2.98 m/s².
• D) 1.53 m/s².
• E) 0.00 m/s².

Inhibitory Synapses

Synaptic connections that decrease the likelihood of the firing action potential of a neuron, thereby reducing neural activity.

Dendritic Spines

Small, protruding structures found on the dendrites of neurons that form synaptic connections and are key to neuronal plasticity and learning.

Habituation

The psychological process by which an individual becomes accustomed to a stimulus through repeated exposure, leading to a decrease in response.

Sensitization

An increased response to a stimulus after repeated exposure, often leading to heightened sensitivity.
