Transcranial magnetic stimulation (TMS) is a noninvasive technique used to stimulate regions of the human brain. A small coil is placed on the scalp, and a brief burst of current in the coil produces a rapidly changing magnetic field within the brain. The...

A Boeing 747 jet with a wingspan of 60.0 m is flying horizontally at a speed of 287 m/s over Phoenix, Arizona, at a location where the Earth's magnetic field is 50.2 µT at 58.0° below the horizontal. What voltage is generated between the wingtips?

A 500 turn solenoid with a length of 20 cm and a radius of 1.5 cm carries a current of 2.0 A. A second coil of four turns is wrapped tightly about this solenoid so that it can be considered to have the same radius as the solenoid. Find the following when...

I was given an equation by bobpursey but I don't know what it means. Considerable scientific work is currently underway to determine whether weak oscillating magnetic fields such as those found near outdoor power lines can affect human health. One study i...

You want to use a windmill to generate electricity for your home. You decide to use Earths magnetic field which has a horizontal component B=10^-4 T to an induce emf. You design a conduction loop with 200 turns and surface area of 0.1m^2. The rod is 0.5m...

1.How many vibrations per second are represented in a radio wave of 101.7 MHz 2.The speed of a wave on a string depends on: a.the material properties of the string b. the amplitude of the wave c.both 3.The time interval for one repetition of the cycle in...

A object-spring system oscillates with an amplitude of 3.8 cm. If the spring constant is 210 N/m and object has a mass of 0.50 kg, find the maximum speed of the object. I already have the mechanical energy of the system. How do I find the maximum speed?

1. A stone is dropped from rest into a well. The sound of the splash is heard exactly 1.50 s later. Find the depth of the well if the air temperature is 10.0°C. 2. Calculate the sound level in decibels of a sound wave that has an intensity of 2.25 µW/m2

A person wants to participate in a bunjee jump. One end of an elastic band 10m long with a spring constant of 50N/m will be attatched to a basket on a crane and the other end to the waist of the person with a mass of 86kg. The person will step off the edg...

I am solving a problem and someone tol me to use this formula MgH = (1/2)*k*(H-2-10)^2 + Mg*2 where did this equation come from. Its not in my book. What concepts does it use? Is it solved correctly? MgH = (1/2)*k*(H-2-10)^2 + Mg*2 MgH = 0.5k(H-12)^2 + 2M...

So i use B=mu*N*i to find a than what does dB/dt=mu*N*di/dt mean?

thanks

I think this is a chemistry question but the atomic number is based on the number of protons in the nucleus of the atom. So the atomic number is 104

could i solve it like this? Fg=Fs mg=kx x=mg/k x=stretch-Eq value stretch=x+Eq value than take the stretch value and add 2.

changes direction due to a change in speed. -got answer from wikipedia

so when i plug the givens into your equation it should look like this (86)(9.8)(?)=(86)(9.8)1/2(50)(h-12)^2 Im confused

so when i plug the givens into your equation it should look like this (86)(9.8)(?)=(86)(9.8)1/2(50)(h-12)^2 im confused

I get 54.5 when I caculate the answer
