What is the magnitude of a vector with components (15 m, 8 m)?

il63 [147K]

The answer is 17 m because you have to add the 15 m and the 8 m together to get the answer so it will be like this 17x17 = 15x15 + 8x8 got it?

A fuse in an electric circuit is a wire that is designed to melt, and thereby open the circuit, if the current exceeds a predete

zmey [24]

Answer:

The diameter of wire should be $4.04 \times 10^{-4}$ m

Explanation:

Given:

Current density $J = 500 \times 10^{4}$ $\frac{A}{m^{2} }$

Current $I = 0.64$ A

From the formula of current density,

$J = \frac{I}{A}$

Where $A =$ area of cylindrical wire = $\pi r^{2}$

$\pi r^{2} = \frac{I}{J}$

$r^{2} = \frac{I}{\pi J }$

$r = \sqrt{\frac{0.64}{3.14 \times 500 \times 10^{4} } }$

$r = 2.02 \times 10^{-4}$ m

For finding the diameter of wire,

$d = 2r$

$d = 4.04 \times 10^{-4}$ m

Therefore, the diameter of wire should be $4.04 \times 10^{-4}$ m

b) Deceleration=(0m/s-282m/s)/1.40s=201.4m/s^2 (here we reject negative because deceleration already take into account negative)
