Your car is traveling at 70/mi/h (1000ft/s) your sneeze and your eyes close for 0.33 seconds how far did you travel during your

Novay_Z [31]

If you're moving at 70 mi/hr, then you cover 33.88 feet in 0.33 sec. If you're moving at 1,000 ft/sec, then you cover 33 feet in 0.33 sec. 70 mph and 1,000 fps are not equivalent. 1,000 fps is about 682 mph, whereas 70 mph is about 103 fps.

(a) Neil A. Armstrong was the first person to walk on the moon. The distance between the earth and the moon is 3.85 x 108 m. Fin

gizmo_the_mogwai [7]

Answer:

a). 1.28333 seconds

b). 186.66 seconds

Explanation:

a). Given :

Distance between the earth and the moon, d = $3.85 \times 10^8$ m

Speed of the radio waves, c = $3 \times 10^8$ m/s

Therefore the time required for the voice of Neil Armstrong to reach the earth via radio waves is given by :

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

$=\frac{3.85 \times 10^8}{3 \times 10^8}$

= 1.28333 seconds

b). Distance between Mars and the earth, d = $5.6 \times 10^{10}$ m

Speed of the radio waves, c = $3 \times 10^8$ m/s

So, the time required for his voice to reach earth is :

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

$=\frac{5.6 \times 10^{10}}{3 \times 10^8}$

= 186.66 seconds

________ states that all current entering a branch point in a circuit must exit.

Aliun [14]

Answer:

The current through a branch is also called the branch current. The current supplied by the battery in a parallel circuit splits at one or more branch points. All of the current entering a branch point must exit again. This rule is known as Kirchhoff's current law
