Two specific situations call for the use of a comma before "and." The first is created when we have three or more items in a series. This mark of punctuation is called the serial comma.The second situation occurs when "and" is being used to coordinate two independent clauses. An independent clause (also known as a main clause) is a group of words that has a subject and a verb, and can stand alone as a sentence.Examples:The man was selling apples and oranges. (no comma)The man was selling apples, oranges, and bananas. (commas after apples, oranges)They went out of town and forgot about the package. (no comma)They had to go out of town, and the package was never delivered.The second clause does not share the subject of the first clause (they) and a comma separates the two thoughts.
Answer #1:Your question cannot be answered without knowing what the pendulum wasfilled with before it was filled with mercury.If it had nothing in it, before, then adding the mercury would increase theperiod time.If it had lead in it before, then adding the mercury would decrease the periodtime.================================Answer #2:The period of a simple pendulum doesn't depend on the weight (mass) of thebob. As long as the bob is much heavier than the string, and air resistance canbe ignored, nothing you do to the bob has any effect on the period.
Inertia is a massive object's resistance to change. It should be obvious then that mass is directly proportional to how long the pendulum swings before coming to rest, since more mass means harder to stop. Mathematically, you'll find this dependence on mass in the damping equations of pendulums.
Answer - None of the above.1. Resistance increases in direct proportion to an increase in length.2. Dielectric constant is the tricky one as the answer may depend on your application. Dieletric constants are usually associated with insulators, not conductors.For fixed voltage/direct current, as long as the dielectric's voltage specifications aren't exceeded, the insulator remains intact. Going beyond that voltage results in current flow (short) and a significant reduction in resistance. So in essence, changing the dielectric constant will alter the resistive properties of your conductor/nonconductor.For situations dealing with alternating currents, capacitance becomes an issue - as there is a current flow as the electric field fluctuates, but just as before - the dielectric constant is not a factor in a component's resistance... until its voltage ratings are exceeded.3. An increase in temperature usually results in a decrease in resistance.4. An increase in cross sectional area results in a decrease in resistance.Note: If "none of the above" is not an option here, then I would have to select #2 as being the answer, with some qualification as noted.
It will rise until the force of gravity on it equals the initial force used to project it upward. At that point, it will momentarily stop before falling back down due to gravity.
You can usually track the package after 48hours

The internal resistance of a device is the resistance in ohms of that device. It is the resistance electrons need to overcome before electricity is said to flow.
Before English, the official language during the period of resistance was Portuguese.
In the letter Peter writes before he dies in "Number the Stars," he asks Annemarie to tell his fiancee, Lise, that he never stopped loving her and that he is waiting for her. He also asks Annemarie to deliver the package he was carrying when he died to a Resistance group.
Yes
That is e.g. the resistance of a cold bulb before the bulb is lighted and heats up.
Tracking information can be at any point after shipping a package.
No it is raw
-- The force of gravity is unchanged before and after.-- The force of air resistance on the skydiver is greater before, and less after,because she is falling slower after the parachute opens.-- The effect on her of air resistance is greater after the parachute is open. Theincreased air resistance itself acts on the parachute, and its effect is transferredto the skydiver through her harness.
Metals that make up typical resistors (and many other electrical components for that matter) tend to heat up as current flows through them. "COLD" resistance is the resistance before it is operating and "HOT" resistance is the resistance after some operating time has elapsed.
