A man with a load jumps from a high building. What will be the load experienced by him

Zero, because while falling, both the man and the load are falling at the same acceleration i.e. acceleration due to gravity.-Everyone knows that when there is a high building somewhere, theres usuall

Trig help.. electricity.. help

Find the combined impedance of the circuit elements in the figure below. The frequency of the current is 75 Hz. 35 Ω95 μF 45 mH-First find the inductive reactance, then the capacitive reactance Xl = 2

The voltage (v) in volts, in a circuit is given by the following expression in the s - domainomain

V(s)=0.02________ 0.02s+1 Determine using inverse Laplace transforms, the voltage in the time domain? Help !-In effect, what you need is inv transform of 0.02/ (0.02s+1). this is of the form 0.02*{1

What is AC RMS voltage

In a question i am asked to find the RMS voltage output of a circuit. The question states the voltage source is AC and has an RMS voltage 20V? Could someone tell me what the things i have to do diffe

X(6x+5)=1 does anyone know how to factor:/

x(6x + 5) =1.............6x^2 + 5x= 1.........6x^2 + 5x -1 = 0 This factors into .......(6x - 1)(x + 1) = 0..............so, x = -1 and x = 1/6-Assuming that your large X is the same as your small x..

How do cars turn? What's the mechanism

I just had this question pop up in my head. How do cars turn? I know that the front wheel makes the car turn... but the back wheel stays straight, doesnt it? So even though the front wheel is at ↗ di

Specific heat physics!!!

What is the specific heat of a metal substance if 139 kJ of heat is needed to raise 5.4kgof the metal from 17.0C to 36.0C?-139 kJ/((5.49 kg)(36-17)) =1.33 joules per gram per degree K

RBE2/RBE3 Dependent Nodes Selecting Problem

Hello I want to create multi point constraint (mpc). Wheni try to create RBE2/RBE3, i cant select dependent nodes correctly. I use polygon pick to select nodes and it selects all nodes.I dont want

Circuits question about voltage

if i have a circuit composed of a 40 volt battery connected in series with a 4 ohm resistor and a 2 henry inductor. What is the voltage across the inductor?-What is the resistance of inductor ? The co

What is i + i^5 - i^76????\

i + i - 1 2i - 1-i + i^5 – i^76 i^5 = i i^76 = i^72 = i^68 ... = i^4 = +1 i + i – 1 = 2i – 1 .

Question about dying oscillations

Lets suppose you have equation of a dying oscillation such as: a*e^(-b*t)*cos(d*x-f) e = math constant for exponential functions How do you determine how long will it take for the function to be alw

Is electrical engineering good career

juts want to know whats so good about electrical engineering..-The short answer is no. Now let me explian why: 1) Offshoring of industrial and engineering jobs to low cost centers ala globalism has

Grade 9 Science-ELECTRICITY( easy points)

what is a source,load,connector and circuit control device. i want the definition and their function-Electrons are sourced from the source, they do work in the load, connectors connect the source and

In a conversion problem involving electricity, what does "e" or "e-" stand for

Im helping my brother who is in grade 9 with his science homework but he forgot his notes at school and I dont remember at all, my future career is not going to involve science so theres no need to re

Roller coaster project for science

Im making a roller coaster model for science--the whole physics in action thing.I need to include 2 loops, 2 hills, and 1 turn.We can have the starting point as high as 1 meter, but no more.Im making
