Answer:

C. tiny particles called charges flowing through the wires.

Explanation:

<h3> Hello!</h3>

An electric current is a stream of charged particles, such as electrons or ions, moving through an electrical conductor or space. It is measured as the net rate of flow of electric charge through a surface or into a control volume.

Hope it helps!

When different resistors are connected in parallel across an ideal battery, we can be certain that: a) their equivalent resistan

sergeinik [125]

Answer:

b) the potential difference across each is the same.

Explanation:

When resistors are connected in parallel with each other

then the terminals of all the resistors will connected across the terminals of the battery

So we know the potential difference of the battery is same across all the resistors

So we can say that the equivalent resistance of all the resistance is

$\frac{1}{R} = \frac{1}{R_1} + \frac{1}{R_2} + \frac{1}{R_3}$

so its not the mean of all resistors

also we know that the resistance are all different so power across each resistance is different given as

$P = \frac{V^2}{R}$

also current in each resistance is also different and given by

$i = \frac{V}{R}$

so correct answer will be

b) the potential difference across each is the same.

There is a simple relationship between the energy for a photon of light Ephoton in units of eV (electron volts) and its waveleng

Eva8 [605]

Answer:

$\lambda=620\ nm$

$E_p=1.9682\ eV$

$E_p=206.67\ eV$ is the photon energy of an x-ray

Explanation:

Given:

Energy of photon, $E_p=2\ eV$

Then according to given:

$E_p=\frac{1240}{\lambda}$

$2=\frac{1240}{\lambda}$

$\lambda=620\ nm$ is the wavelength

Again,

Energy of photon, $E_p=?$

wavelength of the light, $\lambda=630\ nm$

$E_p=\frac{1240}{630}$

$E_p=1.9682\ eV$

<u>Now, photon energy for an x-ray:</u>

wavelength, $\lambda=6\ nm$

$E_p=\frac{1240}{6}$

$E_p=206.67\ eV$ is the photon energy of an x-ray

Which method is not a technique currently used by ocean scientists to map the topography of the ocean floor?

raketka [301]

Answer:

Magnetometer

Explanation:

Magnetometer technique is not using by scientists for studying the ocean floor.The scientists currently is using SONAR ( sound navigation and ragging) technique for studying the ocean floor.SONAR is used sound waves sound waves for studying the ocean floor or we can say that SONAR is based on sound propagation.

Therefore answer is Magnetometer
