Answer:8.28 km
Explanation:
Given
First it drifts 2.5 km
Secondly it drifts 4.70 km
After that it drifted along east direction 5.1 km
After that it drifts 7.2 km
After that it drifts 2.8 km
=+
for direction
south of east
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

As solar wind approaches Earth, what happens to the charged electrons?
They are deflected as Earth’s magnetic field exerts force on them.
Which best describes how energy transferred from an electron in the solar wind compares with energy absorbed by an electron in the oxygen atom?
equal to
Which statement is accurate about how the aurora borealis is formed?
When the electrons fall to a lower energy state, they release energy as electromagnetic radiation, light.
How does the energy in the light of the aurora borealis compare to the energy as an excited electron returns to its original energy level?
equal to
During the formation of the aurora borealis, the electrons in an atom experience a change in energy levels. Which statement about this change is accurate?
First, the electron absorbs energy to move to a higher energy level.
Answer:
x = 625 m
Explanation:
To solve this exercise we use the kinematics relations
v² = v₀² - 2 a x
indicate that the train stops therefore its final speed is zero (v = 0)
0 = v₀² - 2a x
x =
let's slow down to the SI system
v₀ = 90 km / h (1000 m / 1km) (1h / 3600 s) = 25 m / s
let's calculate
x =
x = 625 m
+1
An electron has a negative charge so losing a charge of -1 from an uncharged, or neutral, atom will leave an ion with a positive charge.
