While watching a recent science fiction movie, one Klingon spaceship blows up a Droid spaceship with a laser gun. The Klingon cr

ew watches out the port window and covers their ears to muffle the noise from the explosion. Scientifically, this scene is inaccurate because
A)
light can not reflect off objects in the vacuum of space.



B)
they would not be able to see anything outside the window.



C)
lasers can not be transmitted through the vacuum of space.



D)
the sound of the explosion would not be transmitted back to their ship.

Answer:

D)  the sound of the explosion would not be transmitted back to their ship.

Explanation:

Sound is a mechanical wave. A mechanical wave requires a medium to travel and transfer energy. It travels be compression and rarefaction of the medium. Since in space it is vacuum, the sound energy by the explosion of the spaceship would not be able to travel through the space, the Klingon crew are not required to cover their ears to muffle the noise. This scene would be inaccurate scientifically.

What is the speed of an electron that has been accelerated from rest through a potential difference of 1020 V?
sashaice [31]
<span>a. KE in electron volts is 1020 eV. 
b. KE in Joules is e(1020) = (1.6022E-19)(1020) = 1.634E-16 
c. KE = (1/2)mv^2, so v = sqrt[2*KE/m] = 18.94E6 m/s

note: m is the mass of an electron = 9.109e-31 kg

I hope my answer has come to your help. Thank you for posting your question here in Brainly.

gizmo_the_mogwai [7]

Answer:3.77 T/s

Explanation:

Given

Area of cross-section=3.7\times 3.7 cm^2=13.69 cm^2

N=no of turns=61

Resistance=R=8 \Omega

current (i)=0.04 A

emf induced=i\times R=0.04\times 8=0.32 V

emf induced e=NA\frac{\mathrm{d} B}{\mathrm{d} t}

0.32=62\times 13.69\times 10^{-4}\times \frac{\mathrm{d} B}{\mathrm{d} t}

\frac{\mathrm{d} B}{\mathrm{d} t}=\frac{0.32\times 10^4}{848.78}=3.77 T/s

A ball is thrown upward with a speed of 40 m/s. Approximately how much time does it take the ball to travel from the release loc
zvonat [6]

I'm going to assume that this gripping drama takes place on planet Earth, where the acceleration of gravity is 9.8 m/s².  The solutions would be completely different if the same scenario were to play out in other places.

A ball is thrown upward with a speed of 40 m/s.  Gravity decreases its upward speed (increases its downward speed) by 9.8 m/s every second.

So, the ball reaches its highest point after (40 m/s)/(9.8 m/s²) = <em>4.08 seconds</em>. At that point, it runs out of upward gas, and begins falling.

Just like so many other aspects of life, the downward fall is an exact "mirror image" of the upward trip.  After another 4.08 seconds, the ball has returned to the height of the hand which flung it.  In total, the ball is in the air for <em>8.16 seconds</em> up and down.
