Do you know which component of the Star Wars movies is possible according to our current understanding of physics?

1 answer:

5 0

Although Star Wars have been purely fictional and concerns space travel and Physics, it has some components that is possible according to our current understanding of Physics. Take for example the TIE fighters spacecrafts. It stands for Twin Ion Engine. Currently, Ion engines are being used for actual flight.

A total resistance of 3.03 Ω is to be produced by connecting an unknown resistance to a 12.18 Ω resistance. (a) What must be the

insens350 [35]

Answer:

(a) 4.0334Ω

(b)parallel

Explanation:

for resistors connected in parallel;

$\frac{1}{R_{eq} } =\frac{1}{R1}+\frac{1}{R2}$

Req =3.03Ω , R1 =12.18Ω

$\frac{1}{3.03 } =\frac{1}{12.18}+\frac{1}{R2}$

$\frac{1}{R2}=\frac{1}{3.03 }-\frac{1}{12.18}$

$\frac{1}{R2}=0.2479$

R2=1/0.2479

R2=4.0334Ω

(b)parallel connection is suitable for the desired total resistance. series connection can not be used to achieve a lower resistance as the equation for series connection is.

Req = R1+R2

Two wooden boxes of equal mass but different density are held beneath the surface of a large container of water. Box A has a sma

Novay_Z [31]

Answer:

Box A

Explanation:

Let mass of each wooden box =m

Density of box A= $\rho_A$

Density of box B = $\rho_B$

$\rho_A$

Density, $\rho=\frac{m}{V}$

$V_A=\frac{m}{\rho_A}$

$V_B=\frac{m}{\rho_B}$

Density of inversely proportional to volume.

The volume of box with smaller density is larger than the volume of box with large density.

$V_A>V_B$

When the boxes are submerged under water.

Then, the buoyant force= $\rho_l Vg$

Where V=Volume of displace fluid.

$\rho=$ Density of fluid

Buoyant force of box A= $\rho_lV_Ag$

Buoyant force of box B= $\rho_lV_Bg$

Force=Buoyant force

$ma_A=\rho_lV_Ag$

$ma_B=\rho_lV_Bg$

Acceleration is directly proportional to volume.

Therefore,the box with large volume has greater acceleration.

Hence, the box A has greater acceleration.

In ultimate the disc may be passed in any direction. True False

aleksklad [387]

I think is True: Because...

when you throw a disc you can throw it in any direction, many people call it "Flying Saucer" I'll give you an example ... When you throw something, for example a paper, you want to throw it at your classmate. You already know what address you want to send it to, then I say it is: True ...

Sorry if it's wrong :(

1. A +4 nC charge is placed at a distance r from another charge. If the charge experiences a force of 6000 N, what is the electr

masya89 [10]

Answer:

1500 N/C

Explanation:

From the question,

Applying,

E = F/q.................. Equation 1

Where E = Electric Field intensity, F = Force experienced by the charge, q = Charge

Given: F = 6000 N, q = +4nC

Substitute these value into equation 1

E = 600/4

E = 6000/4

E = 1500 N/C

Hence, the electric field intensity is 1500 N/C.
