Answer:
The magnitude of the lift force L = 92.12 kN
The required angle is ≅ 16.35°
Explanation:
From the given information:
mass of the airplane = 9010 kg
radius of the airplane R = 9.77 mi
period T = 0.129 hours = (0.129 × 3600) secs
= 464.4 secs
The angular speed can be determined by using the expression:
ω = 2π / T
ω = 2 π/ 464.4
ω = 0.01353 rad/sec
The direction
θ = 16.35°
The magnitude of the lift force L = mg ÷ Cos(θ)
L = (9010 × 9.81) ÷ Cos(16.35)
L = 88388.1 ÷ 0.9596
L = 92109.32 N
L = 92.12 kN
The acceleration of gravity on Pluto is 0.62 m/s² .
The acceleration of gravity on Earth is 9.81 m/s² .
Earth's gravity is (9.81/0.62) = 15.8 times as strong as Pluto's gravity.
So any object that weighs 2.7N on Pluto would weigh
(2.7N) x (15.8) = 42.7 N on Earth .
42.7 Newtons = about 9.6 pounds .
Answer: A north pole and a south pole
Explanation: All magnets no matter how big or small they are will always have poles. All magnets have two regions of magnetic strength where they are the strongest. Even if I cut a magnet in half, it would still have poles.
It's important to understand that there like poles repel each other and opposites attract.
Convection is the process of heat transfer in fluids by the actual motion of matter. It happens in liquids and gases. It may be natural or forced. It involves a bulk transfer of portions of the fluid.

Answer:
La aceleración total de la piedra es 2,85 m/s².
Explanation:
La aceleracion total de la piedra viene dado por la suma de la acelaración centrípeta y de aceleración tangencial, como:
La aceleración tangencial () es la aceleracion del cilindro igua a:
Entonces, la aceleración centrípeta es:
En donde:
v: es la velocidad tangencial de la piedra = 2,0 m/s
r: es el radio del cilindro = 1,5 m
Finalmente, el módulo de la aceleración total es:
Por lo tanto la aceleración total de la piedra es 2,85 m/s².
