A rescue pilot drops a survival kit while her plane is flying at an altitude of 2000.0 m with a forward velocity of 100.0 m/s. I

f air friction is disregarded, how far in advance of the starving explorer's drop zone should she release the package?

Answer:

H = 1/2 g t^2 no original vertical velocity

t = (2 * 2000 / 9.8)^1/2 = 20.2 s

Sx = 100 m/s * 20.2 s = 2020 m

What is the atomic weight of a penny?

Gnom [1K]

I actually know the answer to this one, you use pennies to find the atomic weight of a penny, it really doesn't have a weight. LOL

The capacitance of a capacitor depends on what?

bonufazy [111]

Answer:

The capacitance of a capacitor depends on the charge and voltage of a system. It is also dependent, if present, on the dielectric as well.

General Formulas and Concepts:
<u>Gauss's Law</u>

Capacitance Formula: $\displaystyle C = \frac{Q}{V}$

<em>Q</em> denotes charge
<em>V</em> denotes voltage

Dielectric Capacitance Formula: $\displaystyle C = \kappa C_0$

<em>C₀</em> denotes original capacitance
<em>κ</em> denotes the dialectic constant

Explanation:

A <u>capacitor</u> <em>stores</em> charge when run through an electrical current. The <u>capacitance</u> is <em>how much </em>charge a capacitor can hold.

We can define the relationship of capacitance by using the formula. Capacitance is <em>inversely proportional</em> to the potential energy, or <u>voltage</u>, of the system. Therefore, you will need to know what the <u>charge</u> Q of the system as well has voltage V in order to find the capacitance.

If there is a dielectric involved inside the capacitance, you also must incorporate the value of the <u>dielectric constant </u>into your capacitance. A dielectric is <em>directly proportional </em>to the capacitance; the bigger the dielectric constant, the bigger capacitance, as denoted in our equation.

Find the total energy (ft-lb) of an aircraft weighing 20,000 lbs at 5,000 ft true altitude and 200 KTS true air speed. Group of

trapecia [35]

Answer:

Hello the options to your question is missing below are the options

2 x 10^8 ft-lb

15527950 ft-lb

2.8 x 10^7 ft-lb

13.55 x 10^7 ft-lb

Answer : 13.55 * 10^7 ft-Ib

Explanation:

Given data :

weight of Aircraft (p) = 20000 Ibs

height ( h ) = 5000 ft

Velocity = 200 KTS = 370 km/h ( 10277 m/s) where 1 KTS = 1185 km/h

calculate the total energy

Total energy = potential energy + kinetic energy

potential energy = mgh = p * h =20000 * 5000 = 100 * 10^6 ft-Ibs

kinetic energy = 1/2 mv^2 = 1/2 * 625 * (33709)^2 = 3551 *10^6 ft-Ibs

where ; m = p/g = 20000 / 32 = 625 Ibs

v = 10277 m/s ≈ 33709 ft/s

hence total energy = 100 * 10^6 + 3551 * 10^6 = 1355*10^7 ft-Ibs
