Is Copper Wire dangerous to use for circuits

Im planning on making a battery operated light bulb, but im not sure what type of wire to use to connect the bulb to the battery and I was wondering if using copper wire would be dangerous? Is it flam

Simple physics question please help!

An airplane, travelling initially at 240 m/s (28degSofE) takes 35 sec to change its velocity to 220 m/s (28degEofS). What is the average acceleration over this time? Please write down step by step exp

Can the production of plastics be considered an engineering breakthrough

Like when it was first mass produced in the 1940s. Im trying to write a paper for my engineering class.Was it more of a chemical breakthrough or can it be considered an engineering breakthrough?-Yes,

Question about "moments"

i have a question asking me to find the reactionary forces at a point (on a cantilever beam, if that makes a difference).there are only forces in the y direction, so i can find the Y-component from th

What is the fundamental building block of the body

like from the cell like is it a nucleus or a nucleolus or what is it-Neither the nucleus or nucleolus are anymore fundamental parts of the cell than any other of the organelles.You cannot make an endo

How to show that a particle with position vector moves on a circular path, has constant speed, and its...

...velocity is tangent to the circle? The equation for the position vector is r = Asin(wt)i + Acos(wt)j, and a and w are constants. Thanks for any insight!-Consider the distance of r from the origin a

Would putting my electronic devices in a microwave protect it from an EMP attack

I was wondering, cause I read somewhere that the screens used on microwave doors are used to shield military display screens, and the microwave itself has to be surrounded by a grounded metal shell. S

I want some projects for my Btech final year in Mechanical engineering. It must not be very costly.-You can find various projects in the link below.

Help counting with d flip flops

Hey guys. I have to create a sequential circuit using D flip flops that counts 0, 2, 4, 6 repeatedly when input is 1, and 6, 4, 2, 0, when input is 0. I have no idea how to do this and I have been wo

SOLVE this using quadratic formula

the formula is: x=(-b+/- sqrt b^2-4ac)/2a 0=v^2+20v-4800 give me a solution step by step pls-a = 1 b = 20 c = -4800 v = -20 +- sqrt(400 - 4 * 1 * -4800) / 2 * 1 v = -20 +- sqrt(400 + 19,200) / 2

Need to convert 3.2v dc to 5v dc

I have a 3.2v 16ah battery (Lithium iron phosphate) and need to get 5v out of it, i though about a LM7805 regulator, but that requires at least 7.5v input. Any suggestions?-Its not simple, you need a

How to solve e^(5k) = (5/6)k^2 + 3/2 ............

Solve for k? How to solve when we have a natural log, and an unknown with degree of 2?-k = 0.0818358 Solve it by Newtons method.-Dont think you can, except by numerical approximations. a quick exer

What is industrial engineering

What do they do ?-Dear I am... Industrial engineering is a branch of engineering dealing with the optimization of complex processes or systems. It is concerned with the development, improvement, impl

Need serious help Homogeneous Differential Equation

Given (d^2x/dt^2) + 2p(dx/dt) + 169x = 0 which satisfies the conditions t=0, x=0 and dx/dt = 8 Find value of p such that the characteristics equation has repeated roots and determine x in term of t?

Is a crane a type of pulley

No. A crane is a machine to lift heavy things. It usually uses a pulley. A pulley is part of the crane.-i would think its closer to a lever. in fact, its a complicated machine that uses multiple sim
