Architecture question

i have noticed one thing in common about all the places of worship that they all have very high floor-to-floor height. why is this so? is it an architectural requirement of a place of worship?-A large

What is i^71 + i^65????

-i + i 0-i^1 = i i^2 = -1 i^3 = -i i^4 = 1 x^[a+b] = x^a * x^b So... i^71 = 1^[68 + 3] = i^68 * i^3 = 1 * -i = -i i^65 = i^[64 + 1] = i^64 * i^1 = 1 * i = i i^71 + i^65 = 0-Should be 6 x 10^-13 or 0.0

How many chances do we get to take the FE (Fundamentals of Engineering) Exam

something always seems to go wrong with my life, things go bad on important days and Im wondering how many chances we have to take the FE given I may fail or not make it to taking it. what are the r

What is usually taught/covered in a class called Intro. to Computer Systems (At a 2 year college.)

Just the main things, or as detailed as you can be about what the class is about, and the main things the class covers and goes over?-I expect you would cover binary numbers, basic parts of a computer

What is the Steam Turbine

The dry and superheated steam from the super heater is fed to the steam turbine through main valve. The heat energy of steam when passing over the blades of turbine is converted into mechanical energy

Which is the best metric unit to measure the volume of a gas truck

I dont know about best, but the standard is the cubic meter, or m³, and derivatives of that such as cm³ or mm³ You can use liters also, with 1000 liters = 1 m³ and derivatives such as mL liters are a

What kind of resistor

I am powering a LED that takes 3 volts and powering it with 12 volts what resistors would take the 12 volts down to 3?-Depends on the current spec on the LED. If it is 20 mA, for example, R = E/I =

Engineering mechanics statics questions involving reactions....

A force P of magnitude 450N is applied to member AB which is supported by a frictionless pin at A and by the cable BDC. Since the cable passes over a pulley at D, the tension may be assumed to be the

What is the cost to send a satellite

What is the cost to send up a satellite to space? For the satellite owner. The satellite can be part of a group of satellites to be sent by a rocket for that launch. Lets say the satellite is a small

Stokes' Theorem to evaluate ∫∫ curl F · dS

F(x,y,z) = x^2*y^3*z i + sin(xyz) j + xyz k S is the part of the cone y^2 = x^2+z^2 that lies between the planes y = 0 and y = 3, oriented in the direction of the positive y-axis.-2187pi/4

What is the length of the curve

So first, youll need to find dy/dx, the derivative. Use the derivative rule for ln x (its 1/x) and the chain rule to find the derivative (dy/dx). Once you get that, plug that into the equation I menti
