When a skydiver jumps from an airplane the distance d in feet the diver falls in t seconds before opening the parachute is given by the formula Test Image. The formula assumes that there is no air res?
If d = 16*t^2 then there is no significant air resistance.
Do you use a comma before and?
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.
How is inertia related to pendulums?
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.
How is the the time period of a pendulum affected when the bob of the simple pendulum is filled with mercury?
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.
Which one of the following does not affect resistance of a wire 1 length 2 dielectric contstant 3 temperature 4 cross-sectional area?
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.
A ball is dropped from a 150-m tall building Neglecting air resistance what will the speed of the ball be when it reaches the ground 5.5 seconds later Apex?
Disregarding air resistance, what is the speed of a ball dropped from 12 feet just before it hits the ground? (Use 1 ft = 0.30 m, and use g = 9.8 m/s2.)
How long does it take before you can track a ems package?
You can usually track the package after 48hours
Define Internal Resistance?
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.

What does peter request in his letter he writes before he dies in number the star?
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.
What are cold resistance and hot resistance?
Metals heat up as electrical currents flow through them. Cold resistance is the metals resistance before it is operating. Hot resistance is the metals resistance after operating time has elapsed some.
What is cold resistance?
That is e.g. the resistance of a cold bulb before the bulb is lighted and heats up.
Do they cook frozen fries before they package them?
Yes
How long after shipping a package is it before you can access the UPS tracking information online?
Tracking information can be at any point after shipping a package.
Compare the effects of gravity and air resistance on a falling skydiver before and after she opens her parachute.?
-- 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.
