Adiabatic rate is used to describe the change in temperature as a result of the rising or the sinking of an air parcel.
Knowing that the dry adiabatic rate of change for unsaturated air is 10°C/1000 m means that the temperature of the unsaturated air parcel would increase (get warmer) as the air parcel sinks and will decrease (get cooler) as the air parcel rises.
Hope this helps :)
Answer:
The magnets need to be placed with red closest to blue.
Opposite poles attract.
The magnets will be attracted to each other with enough force to stick together.

Answer:
Explanation:
The acceleration of an object down a slope (neglecting friction, µ = 0) is:
a = g × sin θ
Where,
g is the acceleration due to gravity and θ is the angle of the slope.
a = (9.8 × sin (21.5º)
= 3.592 m/s²
Using equations of motion,
S = ut + 1/2at²
Since, u = 0,
S = 1/2at²
347 = 1/2 × (3.592)t²
t² = 193.21
= sqrt(193.21)
= 13.9 s.
Answer:
the answer the correct is 3
Explanation:
Let's use the relationship between momentum and momentum
I = Δp
I = m 
- m v₀
Let's calculate
I = 0.4 5.0 - 0
I = 2.0 N s
By Newton's law of action and reaction the force on the ball is equal to the force that the ball exerts on the foot, therefore the impulse on the foot of equal magnitude, but in the opposite direction
I = 2.0 Ns with 60°
When reviewing the answer the correct is 3
