The distance versus this plot for a particular object shows a quadratic relationship. Which column of distance data is possible

SOVA2 [1]

Answer:

Explanation:

In Column A, the pattern is 1², 2², 3², etc. So x(t) = t², which is quadratic.

In Column B, the pattern is 2*1, 2*2, 2*3, etc. So x(t) = 2t, which is linear.

In Column C, the pattern is 9*1, 9*2, 9*3, etc. So x(t) = 9t, which is linear.

In Column D, the pattern is 1/1, 1/2, 1/3, etc. So x(t) = 1/t, which is reciprocal.

In Column E, the pattern is 1/1², 1/2², 1/3², etc. So x(t) = 1/t², which is reciprocal.

Some superconductors are capable of carrying a very large quantity of current. If the measured current is 1.00 ´ 105 A, how many

Zielflug [23.3K]

Answer:

The $6.25 \times 10^{23}$ electrons are moving through the superconductor per second.

Explanation:

Given :

Current $I = 1 \times 10^{5}$ A

Charge of electron $e = 1.6 \times 10^{-19}$ C

Time $t = 1$ sec

From the formula of current,

Current is the number of charges flowing per unit time.

$I = \frac{ne}{t}$

Where $n =$ number of charges means in our case number of electrons

$n = \frac{It}{e}$

$n = \frac{1 \times 10^{5} }{1.6 \times 10^{-19} }$

$n = 6.25 \times 10^{23}$

Therefore, $6.25 \times 10^{23}$ electrons are moving through the superconductor per second.
