I know that Tokyo commonly has several earthquakes, due to the fact that it lies on top of a fault line and that Tokyo has several tsunamis, like they did a few years ago. Several thousand were killed and went missing.
Answer:
It looks like A is the correct answer.
Answer:
F = 153637 lb
Explanation:
Let's use the kinematic equations to find the airplane's braking speed
v² = v₀² + 2 a d
The final speed is zero
a = - v₀² / 2d
Let's reduce the magnitudes
v₀ = 110 mi / h (5280 ft / 1 mile) (1 h / 360 s) = 161.33 ft / s
a = -161.33²/2 90
a = -144.60 ft / s²
Now we can use Newton's second law to find the tension
F = m a
F = (34000/32) 144.60
F = 153637 lb
Answer:
The mass is 16 [g]
Explanation:
We have to remember the formula that defines density, which mentions that the density is equal to mass divided by the volume.
![Density = mass / volume\\where:\\density = 2[\frac{g}{cm^{3} } ]\\Volume = 8 [cm^{3}]](https://tex.z-dn.net/?f=Density%20%3D%20mass%20%2F%20volume%5C%5Cwhere%3A%5C%5Cdensity%20%3D%202%5B%5Cfrac%7Bg%7D%7Bcm%5E%7B3%7D%20%7D%20%5D%5C%5CVolume%20%3D%208%20%5Bcm%5E%7B3%7D%5D)
Now we clear the mass:
![mass= density*volume\\mass = 2[\frac{g}{cm^{3} }]*8[cm^{3} ]\\mass = 16 [g]](https://tex.z-dn.net/?f=mass%3D%20density%2Avolume%5C%5Cmass%20%3D%202%5B%5Cfrac%7Bg%7D%7Bcm%5E%7B3%7D%20%7D%5D%2A8%5Bcm%5E%7B3%7D%20%5D%5C%5Cmass%20%3D%2016%20%5Bg%5D)
