Answer:
560 m
Explanation:
The speed of sound in air is approximately:
v ≈ v₀ + 0.6T
where v₀ is the speed of sound at 0°C (273 K) in m/s, and T is the temperature in Celsius.
The speed of sound at 20°C at that altitude is:
v ≈ 327 + 0.6(20)
v ≈ 339 m/s
The sound travels from the hikers to the mountain and back again, so it travels twice the distance.
339 m/s = 2d / 3.3 s
2d = 1118.7 m
d = 559.35 m
Rounding, the mountain is approximately 560 m away.
The equation that shows the relationship between X₁ and X₂ in the springs is X₁ = 4X₂.
<h3>How to compute the equation?</h3>
From the complete question, for case I, the two springs stretch up to the distance of X₁. Therefore, f = mg = kx₁.
For case 2, f = mg = kx₂.
Therefore, we'll equate the equations. This will be:
Kx₁ = Kx₂
(K/2)x₁ = (2k)x₂
K(x₁/2) = k(2x₂)
X₁/2 = 2x₂
X1 = 2 × 2x₂
X₁ = 4X₂.
In conclusion, X₁ = 4X₂.

Answer:
Magnetic quantum number.
Explanation:
Orbitals with the same principal quantum number and the same l value belong to the same subshell.
The magnetic quantum number, ml distinguishes the orbitals available within a subshell, and is used to calculate the azimuthal component of the orientation of space.
The value of ml can range from -ℓ to +ℓ. The s, p, d, and f subshells contain 1, 3, 5, and 7 orbitals each, with values of m within the ranges 0, ±1, ±2, ±3 respectively while containing 2 different spin electrons.
<span>Every falling object on Earth will experience air resistance,
unless it's falling inside a vacuum chamber.
The air resistance will increase as the speed of the falling object
increases.
At the point when the air resistance equals the weight, there is no
acceleration, and the object will fall with constant speed after that.</span>
Well! see the car experiences 300 N force to the right from the engine.
It also experiences 150N force to left due to friction and air resistance
Now, we know it is the net force which will decide the car will move in which direction
We have net force=300-150=150N
which is towards right
So that means car will accelerate in right direction.
Hope it helps!!
