Answer:
The Kobe earthquake is 1.1 times more intense than the Northridge earthquake.
Explanation:
In order to answer the question, you have to calculate the rate of the two earthquakes, that way you will obtain how many times more intense was the Kobe earthquake compared to the Northridge earthquake.
The rate is obtained dividing the magnitude of the Kobe earthquake by the magnitude of the Northridge earthquake:
Rounding to one decimal place:
Rate=1.1
Let K and N represent the intensity of the Kobe and Northridge earthquakes, respectively. Therefore the rate can be written as:
The Kobe earthquake is 1.1 times more intense than the Northridge earthquake.
Answer:
If a vertical line extending down from an object's CG extends outside its area of support, the object will topple
Explanation:
We can understand better this situation using a diagram with the forces acting on it.
In the attached image we can see that when the gravity center is bouncing outside from the area of the pedestal, the object will be out of balance and will fall.
Energy of motion is the literal definition of kinetic energy
Answer:
Correct answer: E total = 2,800 J
Explanation:
Given:
m = 4 kg the mass of the object
V = 20 m/s the speed (velocity) of the object
H = 50 m the height of the object above the surface
E total = ? J
The total energy of an object is equal to the sum of potential and kinetic energy
E total = Ep + Ek
Ep = m g H we take g = 10 m/s²
Ep = 4 · 10 · 50 = 2,000 J
Ek = m V² / 2
Ek = 4 · 20² / 2 = 2 · 400 = 800 J
E total = 2,000 + 800 = 2,800 J
E total = 2,800 J
