Half note

Explanation:

The denominator of the time signature is 2, so the half note gets one beat (1=whole, 2=half, 4=quarter, 8=eighth, etc.)

A really easy way to understand a time signature is to say "there are [numerator] [denominator] notes in a measure." So 3/2 is "there are three, half notes in a measure."

only #2 represents an object at rest on a table.

in #1, there is no normal force due to the table; the object is accelerating downward.

in #3, the vertical forces are not balanced; the object is accelerating downward.

in #4, neither the vertical nor the horizontal forces are balanced. the object is accelerating upwards and to the right.
