Answer:
runway use is 3307.8 feet
Explanation:
given data
velocity = 140 kts = 140 × 0.5144 m/s = 72.016 m/s
time = 28 seconds
weight = 28000 lbs
to find out
How many feet of runway was used
solution
we will use here first equation of motion for find acceleration
v = u + at ..............1
here v is velocity given and u is initial velocity that is 0 and a is acceleration and t is time
put here value in equation 1
72.016 = 0 + a(28)
a = 2.572 m/s²
and
now apply third equation of motion
s = ut + 0.5×a×t² .......................2
here s is distance and u is initial speed and t is time and a is acceleration
put here all value in equation 2
s = 0 + 0.5×2.572×28²
s = 1008.24 m = 3307.8 ft
so runway use is 3307.8 feet
Radiocarbon saying assume the half life for radioistopes change over time. The half life of C -14 is 5730 years
Answer:
a)P/Po=0.263
b)γ=1.33 So gas is triatomic
c)
Explanation:
a)
initial pressure = Po
Initial volume = Vo
Final volume = 3.8 Vo
Lets take final pressure is P
we know that for free expansion process
PV= Constant
Po x Vo = P x 3.8 Vo
P=0.263 Po
So
P/Po=0.263
b)
Now gas is compressed in adiabatic manner
Final pressure = 1.56 Po
=1.56 Po
We know that for adiabatic process
γ=1.33 So gas is triatomic
c)
We know that average kinetic energy given as

It was important because it tells why the denser material had sunken and the lighter is floating on the surface.
<u>Explanation:</u>
Eventually, after around 500 million years, our young planet's temperature warmed to the liquefying purpose of iron—about 1,538° Celsius (2,800° Fahrenheit). This crucial crossroads in Earth's history is known as the iron fiasco. The iron fiasco permitted more prominent, progressively quick development of Earth's liquid, rough material.
We also know that at one point all the material in the planet was molten because the denser material had sunk and the lighter was floating.
It's true charged particles are always acted on by an electric field.when the velocity of the electron is parallel to the magnetic field, the magnetic force vanishes.
