) Calculate current passing in an electrical circuit if you know that the voltage is 8 volts and the resistance is 10 ohms

Svetach [21]

Explanation:

Hey, there!

Here, In question given that, 

potential difference (V)= 8V

resistance (R)= 10 ohm

Now,

According to the Ohm's law,

V= R×I { where I = current}

or, I = V/R

or, I = 8/10

Therefore, current is 4/5 A or 0.8 A.

(A= ampere = unit of current).

Hope it helps...

A string is 3.00 m long with a mass of 5.00 g. The string is held taut with a tension of 500.00 N applied to the string. A pulse

NISA [10]

Answer:

The time interval is $t = 5.48 *10^{-3} \ s$

Explanation:

From the question we are told that

The length of the string is $l = 3.00 \ m$

The mass of the string is $m = 5.00 \ g = 5.0 *10^{-3}\ kg$

The tension on the string is $T = 500 \ N$

The velocity of the pulse is mathematically represented as

$v = \sqrt{ \frac{T}{\mu } }$

Where $\mu$ is the linear density which is mathematically evaluated as

$\mu = \frac{m}{l}$

substituting values

$\mu = \frac{5.0 *10^{-3}}{3}$

$\mu = 1.67 *10^{-3} \ kg /m$

Thus

$v = \sqrt{\frac{500}{1.67 *10^{-3}} }$

$v = 547.7 m/s$

The time taken is evaluated as

$t = \frac{d}{v}$

substituting values

$t = \frac{3}{547.7}$

$t = 5.48 *10^{-3} \ s$
