A wire carries a current of 4.1 A. How many electrons per second are passing any cross sectional area of the wire? Enter your an
aivan3 [116]

To solve this problem it is necessary to apply the concepts related to Current and Load.

The current in terms of the charge of an electron can be expressed as

i = \frac{q}{t}

Where,

q = Charge

t = time

At the same time the Charge is the amount of electrons multiplied by the amount of these, that is

q = ne

Replacing in the first equation we have to

i = \frac{q}{t}

i = \frac{ne}{t}

Clearing n,

n = \frac{it}{e}

Here the time is one second then

n = \frac{i}{e}

n = \frac{4.1}{1.6*10^{-9}}

n = 2.56*10^{19}electrons

Therefore the number of electrons per second are passing any cross sectional area of the wire are 2.56*10^{19}electrons

How would radiation occur in space?
Marizza181 [45]

Answer:

Space radiation is made up of three kinds of radiation: particles trapped in the Earth's magnetic field; particles shot into space during solar flares (solar particle events); and galactic cosmic rays, which are high-energy protons and heavy ions from outside our solar system.

A sled is moving at a constant speed down a surface inclined at 45 degrees with the horizontal and travels 30meter in 4 seconds.
Vika [28.1K]
Constant speed along the inclined surface = 30 m / 4 s = 7.5 m/s

Vertical speed = inclined speed * sin(45) = 7.5 *√2 / 2 = 5.3 m/s

Answer: 5.3 m/s
