Explanation:
We use Hooke's Law, which states that,
F=kx
F- is the force in newtons
k- is the spring constant
x- is the extension of the spring in meters
Solving for k we get k=F/x
k= 10N/0.50m
=100 N/m
Answer:
32°
Explanation:
From the diagrammatic representation of the question,
Point A is the pilot point of view from the airplane
Point C is the foot of the first tree
Point D is the foot of the second tree
Line AB is the height of the airplane from the ground level.
Line CD is the distance between the two trees
Considering ΔABC,
tan 33°
BC = 5000 / tan 33°
BC = 7,699.41 feet
BD = BC + CD
BD = 7,699.41 + 300
BD = 7,999.41 feet
Considering ΔABD,
tan θ
tan θ
tan θ = 0.6250
θ = tan⁻¹ 0.6250
θ = 32°
Answer:
We multiply 4.24 by 38.0 to get the answer.

Answer:
20,000, though, I'm not completely sure.
Explanation:
"Sound is generated along the length of the lightning channel as the atmosphere is heated by the electrical discharge to the order of 20,000 degrees C (3 times the temperature of the surface of the sun)."
