A "seismograph" is a machine designed to detect and record
the tiny motions of the ground caused by earthquakes.

"seism-" . . . . . related to earthquakes

"graph" . . . . . picture or drawing .

More than one seismograph is a bunch of 'seismographs' ... no apostrophe.

The picture that the seismograph draws is a ' seismogram ' .

Two ideal solenoids of radii R and 4 R , respectively, have n turns per meter, and each carries a current of I . Both currents f

telo118 [61]

Answer:

The formula for the calculation of the magnetic field inside a solenoid is

B = μo*n*I

where

μo: vacuum permeability

n: turns per meter

I: current

The magnetic field inside de solenoid is constant. In the case of a small-radius solenoid inside a large-radius solenoid, the magnetic field inside the small-radius solenoid is the magnetic field generated by itself plus the magnetic field generated by the large-radius solenoid. (The radius of the solenoids does not have to be with the instensity of the magnetic field):

BT = Bs + Bl

Bs: magnetic fiel of the small-radius solenoid

Bl: magnetic fiel of the large-radius solenoid

Hence:

BT = 2*μo*n*I

Digestion is the breaking up of food in your stomach by gastric acids. Then, it gets converted into enzymes, builds up near the rectum, and makes poop.

You will use the equation for work which is w= F times distance so you will take 40N times 36N which equals 1440N

A 0.0223 m diameter coin rolls up a 12.0◦ inclined plane. The coin starts with an initial angular speed of 49.3 rad/s and rolls

zlopas [31]

Answer:

$h = 0.0231 m$

Explanation:

The movement of the coin is modelled after the Principle of Energy Conservation. The kinetic energy of the coin is the sum of the components associated with translation and rotation and there are no non-conservative forces. In addition, the coin starts moving at height of zero

$K_{rot} + K_{tr} = U_{g}$

$\frac{1}{2} \cdot m_{coin} \cdot \omega^{2} \cdot R^{2} + \frac{1}{4} \cdot m_{coin} \cdot R^{2} \cdot \omega^{2} = m_{coin} \cdot g \cdot h\\$

$\frac{3}{4} \cdot R^{2} \cdot \omega^{2} = g \cdot h$

The maximum vertical height is isolated in the previous equation:

$h = \frac{3 \cdot R^{2}\cdot \omega^{2}}{4\cdot g}$

$h = \frac{3 \cdot (0.01115 m)^{2} \cdot (49.3 \frac{rad}{s} )^{2}}{4 \cdot (9.807 \frac{m}{s^{2}} )} \\h = 0.0231 m$
