Hypocenter (under the ground where earthquake actually begins), or epicenter(above hypocenter on the ground, useful to locate on the map)
You will get 20460000 as your answer which is broken down into, 2.046 x 10^7 as your number has to be between 1-10.
Answer: velocity has a direction, while speed is the distance travelled by an object.
Explanation:
The energy that the rope absorbs from the climber is Ep=m*g*h where m is mass of the climber, g=9.81m/s² and h is the height the climber fell. h=4 m+2 m because he was falling for 4 meters and the rope stretched for 2 aditional meters. The potential energy stored in the rope is Er=(1/2)*k*x², where k is the spring constant of the rope and x is the distance the rope stretched and it is
x=2 m. So the equation from the law of conservation of energy is:
Ep=Er
m*g*h=(1/2)*k*x²
k=(2*m*g*h)/x² = (2*60*9.81*6)/2² = 7063.2/4 =1765.8 N/m
So the spring constant of the rope is k=1765.8 N/m.
Answer:
the level of water will rise
Explanation:
The density of stones is more than the density of water. So, when the stones are dropped into the water, the stone replaces the volume of water equal to the volume of stones.
