Answer:
The radius of the loop is 20.66 km
Explanation:
let the radius of the loop be r
mass of airplane is m
At the top, the pilot experiences two radial forces, which are
1) Gravitational force is mg
2) Centrifugal forces mv²/r out of the center
When the pilot experiences no weight,
then, mg = mv²/r
r = v² / g
= 450² / 9.8
= 20.66 x 10³3
= 20.66 km
Answer:
v₀ = 26.17 m/s
Explanation:
If
R = Xmax = 50 yards = (50 yards)*(0.9144 m / 1 yard) = 45.72 m
t = 5 s (Time of Flight)
we can apply the equation:
R = V₀x*t ⇒ V₀x = R / t = 45.72 m / 5 s ⇒ V₀x = 9.144 m/s
then we use the equation of Time of Flight:
t = 2*V₀y / g ⇒ V₀y = g*t / 2 = (9.81 m/s²)*(5 s) / 2 ⇒ V₀y = 24.525 m/s
Finally we apply
v₀ = √(V₀x² + V₀y²) ⇒ v₀ = √(9.144² + 24.525²) m/s
⇒ v₀ = 26.17 m/s

The universe is the collection of galaxies, The Andromeda Galaxy has spectral lines with blue shift. The conclusion is that the Universe has stopped expanding.
<h3>What is Andromeda Galaxy?</h3>
The Andromeda Galaxy is the nearest spiral neighbor that has spectral lines showing a blue shift.
Therefore, this concludes that, the Universe has stopped expanding. This galaxy is slowly shifting towards us.

Answer:
He is wrong!
Explanation:
Frequency refers to how many wave lengths pass in a second and speed is how fast the wave is traveling for example the speed of light goes really fast but has a mid-level frequency.
Hope this helps! ;-)
