Comparing to current technology, here are some component of star wars that is possible :
- The drones
Remember the flying drones that could shoot stuff in star wars ? we already made that
- Prosthetic limb
Luke's bionic hand in star wars ? we also already made that
- The probe droids
We used a similar thing when our scientist done an expedition to the moon
Answer:
(D )
and 
Explanation:
Given that, the rms value of current is 10 ampere and its frequency is 50 Hz.
Now maximum value of current can be calculated as,

The time period is defined as,

Now the time taken by alternating current going from zero to maximum value is,

Therefore, the time taken by alternating current to reach maximum value is
and the peak value of current is
.
Answer:
The wavelength of the given radiation is 0.327 m
Explanation:
The wavelength and the frequency of a wave are related by the formula, given below:
v = fλ
where.
v = speed of wave
f = frequency of wave = 915 MHz = 915000000 Hz
λ = wavelength of the wave = ?
For the electromagnetic radiations we know that:
v = c = speed of light = 3 x 10^8 m/s
Therefore,
c = fλ
λ = c/f
λ = (300000000 m/s)/(915000000 Hz)
<u>λ = 0.327 m</u>
Answer:
The correct answer is option 'a': It decreases with increase in altitude
Explanation:
Acceleration due to gravity is the acceleration that a body is subjected to when it is freely dropped from a height from surface of any planet, ignoring the resistance that the object may face in it's motion such as drag due to any fluid.. The acceleration due to gravity is same for all the objects and is independent of their masses, it only depends on the mass of the planet and the radius of the planet on which the object is dropped. it's values varies with:
1) Depth from surface of planet.
2)Height from surface of planet.
3) Latitude of the object.
Hence it neither is a fundamental quantity nor an universal constant.
The variation of acceleration due to gravity with height can be mathematically written as:

where,
R is the radius of the planet
is value of acceleration due to gravity at surface.
hence we can see that upon increase in altitude the value of 'g' goes on decreasing.
