15 to 35 degrees of equator
Answer:d
Explanation:
Eiffel tower is made up of puddling of cast iron and trusses to provide fire-resistant material. Around 7000 metric tons of puddling iron is used to construct the Eiffel Tower. The structure composed of four large arched legs, upright on masonry columns that joined to become one.
Effiel tower uses the criss-cross beams structure called trusses which provide strength to the structure. The strength comes from the inherent stability of triangular structures.
Answer:
x_total = 20m
Explanation:
This is an exercise in kinematics, we will look for the distance it travels during the reaction time, where there is no braking, and then the distance during the deceleration.
Distance traveled during response time
v = x₁ / t
x₁ = v t
let's calculate
x₁ = 10 0.75
x₁ = 7.5 m
Now we calculate the distance during braking, the final speed is zero (v = 0)
v² = v₀² - 2 a x₂
x₂ = v₀² / 2 a
let's calculate
x₂ = 10² / (2 4)
x₂ = 12.5m
the total stopping distance is
x_total = x₁ + x₂
X_total = 7.5 + 12.5
x_total = 20m
When two waves intersect, they interfere and dan at the crossing point one resulting from well-defined characteristics - the combination of the two-product, but continue unchanged one to the other, each conveying his energy.
