Answer and Explanation:

The binary system is a star system about half of the star are the part of the binary system

The important binary systems are

Visual binary : in visual binary system the two stars resolved visually with nay sort of optical device the orbit of binary orbit is very large about center of mass.
Spectroscopic binary : in this binary system the stars are detected by close analysis of light and after detection it is found that there are two seller spectrum present instead of one.
Eclipsing binary : eclipsing binary system is a several types of variable stars this binary system is very important in astrophysics

The current supplied by a battery as a function of time is I(t) = (0.88 A) e^(-t*6 hr). What is the total number of electrons tr

Nimfa-mama [501]

Answer:

$N = 1.2 \times 10^{23}$

Explanation:

As we know that the current through the battery is given as

$i = (0.88 A) e^{-t/6}$

here from above equation we know that current will become zero when time elapsed is very large

so here we can say that charge will flow through the battery from t = 0 to t = infinite

now we have

$q = \int i dt$

$q = \int (0.88 A) e^{-t/6} dt$

$q = 0.88\times -6(3600)\times (e^{-t/6})$

$q = -1.90 \times 10^{4} (0 - 1)$

$q = 1.90 \times 10^{4} C$

As we know that

$q = Ne$

$N = \frac{q}{e}$

$N = \frac{1.90 \times 10^4}{1.6 \times 10^{-19}}$

$N = 1.2 \times 10^{23}$

Please help!

Since there is no air resistance, gravity is the only force acting on the two objects - the bowling ball and the arrow. Therefore, they will hit the ground at the same time. Thus the answer is D. Both hit the ground at the same time. Hope this helped and have a great day!

What are the three subatomic particles of an atom?

Anestetic [448]

Protons, neutrons, and electrons are the three main subatomic particles found in an atom. Protons have apositive (+) charge. An easy way to remember this is to remember that both proton and positive start with theletter "P." Neutrons have no electrical charge.
