When the temperature increases the volume will increase, and when it cools it will decrease. This is because the molecules spread further apart as the temp gets higher, which creates a bigger volume.

During normal beating, the heart creates a maximum 4.10-mV potential across 0.350 m of a person's chest, creating a 1.00-Hz elec

Nikolay [14]

Explanation:

Given that,

Maximum potential, V = 4. mV

Distance, d = 0.350 m

Frequency of the wave, f = 100 Hz

(a) The maximum electric field strength created is given by:

$E=\dfrac{V}{d}\\\\E=\dfrac{4.1\times 10^{-3}}{0.350 }\\\\E=0.0117\ V/m$

(b) The corresponding maximum magnetic field strength in the electromagnetic wave is given by :

$B=\dfrac{E}{c}\\\\B=\dfrac{0.0117}{3\times 10^8}\\\\B=3.9\times 10^{-11}\ T$

$\lambda=\dfrac{c}{f}\\\\\lambda=\dfrac{3\times 10^8}{100}\\\\=3\times 10^6\ m$

So, the wavelength of the electromagnetic wave is $3\times 10^6\ m$ .

Two technicians are discussing a state emission test. Technician A says that a vent valve that is not able to close can cause th

Stolb23 [73]

Answer: correct option is C

both Technicians A and B are right

Explanation:

Test cycles specify the specific conditions under which the engine or vehicle is operated during the emission test. The vent valve that is not able to close can cause the system to fail the on-board test. Also, a leaking gas cap can cause a failure of the EVAP test.

There are many different test cycles issued by various national and international governments and working groups
