If the moon disappeared what effect would this have on the earths tides
iogann1982 [59]
The moon has a huge impact on the tides. With the Moon gone, the oceans would become much calmer. The Sun still has its effect on them known as the solar tides. Surfers wouldn't be completely devoid of waves.

A TMS (transcranial magnetic stimulation) device creates very rapidly changing magnetic fields. The field near a typical pulsed-
GrogVix [38]

Explanation:

It is given that, the field near a typical pulsed-field machine rises from 0 T to 2.5 T in 200 μs

Change in magnetic field, dB=2.5\ T

Change in time, dt=200\ \mu s=200\times 10^{-6}\ s=2\times 10^{-4}\ s

Diameter, d = 2.3 cm

Radius, r = 0.0115 m

Emf is induced in the ring as the field changes. It is given by :

E=\dfrac{d\phi}{dt}

E=\dfrac{d(B.A\ cos(0))}{dt}

E=A\dfrac{d(B)}{dt}

E=\pi (0.0115)^2\dfrac{2.5}{2\times 10^{-4}}

E = 5.19 volts

So, the emf induced in the ring is 5.19 volts. Hence, this is the required solution.

Is this a chemical or physical change
Mumz [18]
Good question.  if it's a physical change what you would see is a change in the physical object/appearance like let's say I Tear a piece of paper, that would be a Physical change.  I believe your answer would be a chemical change.
