Answer: They’d fall at the same speed, because air resistance is the only thing that makes an object fall faster than another. There’s a video somewhere on the internet of a bowling ball and a feather falling at the same speed in a vacuum, if you look for it. Hope this helps!

Why can someone standing behind a mirror not see the image?

ANTONII [103]

Answer:

The image behind the mirror is called a virtual image because it cannot be projected onto a screen—the rays only appear to originate from a common point behind the mirror. If you walk behind the mirror, you cannot see the image, because the rays do not go there

When the starter motor on a car is engaged, there is a 300 A cunent in the wires between the bauery and the motor. Suppose the w

docker41 [41]

Answer:

diameter of transmission is 3.473 mm

Explanation:

given data

current = 300 A

total wire length = 1.0 m

voltage drop = 0.55 V

solution

as here Resistivity of copper is = 1.68 × $10^{-8}$ ohm- m

so we get here resistance of wire that is

resistance = $\frac{V}{I}$ ..............1

R = $\frac{0.55}{310}$

R = 1.774 × $10^{-3}$ ohm

and now we get diameter of wire that is

R = $\frac{\rho l}{A}$ .............2

$\pi \frac{d^2}{4} = \frac{\rho l}{R}$

d² = $\frac{4\rho l}{\pi R}$ ...............3

put here value

d² = $\frac{4\times 1.68\times 10^{-8} \times 1}{\pi \times 1.774\times 10^{-3}}$

d = $\sqrt{12.064\times 10^{-6}}$

d = 3.473 × $10^{-3}$ m

d = 3.473 mm

so diameter of transmission is 3.473 mm
