Why does electrical energy decrease the farther it travels in wires?

Because as energy flows some energy goes away because when it moves it use some energy!Think of it like....An Ice cube!If you put it on the table it starts to move and the move it move the more(energy)it uses so after time the ice is not as big as before.

A 7.50 kg bowling ball has 70.4<br> kg•m/s of momentum. What is its<br> velocity?

dolphi86 [110]

Answer:

<h2>9.39 m/s</h2>

Explanation:

The velocity of the bowling ball can be found by using the formula

$v = \frac{p}{m} \\$

p is the momentum

m is the mass

From the question we have

$v = \frac{70.4}{7.5} \\ = 9.38666666..$

We have the final answer as

<h3>9.39 m/s</h3>

Hope this helps you

A pilot flies her route in two straight-line segments. The displacement vector A for the first segment has a magnitude of 243 km

velikii [3]

Answer:

a) $R=126Km$

b) $\theta=74.6\textdegree$

Explanation:

From the question we are told that:

1st segment

243km at Angle=30

2nd segment

178km West

Resolving to the X axis

$F_x=243cos30+178$

$F_x=33.44Km$

Resolving to the Y axis

$F_y=243sin30+178sin0$

$R=\sqrt{F_y^2+F_x^2}$

$F_y=121.5Km$

Therefore

Generally the equation for Directional Angle is mathematically given by

$\theta=tan^{-1}\frac{F_y}{F_x}$

$\theta=tan^{-1}\frac{121.5}{33.44}$

$\theta=74.6\textdegree$

Generally the equation for Magnitude is mathematically given by

$R=\sqrt{F_y^2+F_x^2}$

$R=\sqrt{33.44^2+121.5^2}$

$R=126Km$
