Answer:
killing all of the population if it gets to population of the thing gets to big
Explanation:
1) Forces acting on your body: force of gravity and normal reaction
2) Due to Newton's second law, N = mg
Explanation:
1)
When you sit on the computer, there are only two forces acting on you:
- The force of gravity, acting downward, of magnitude , where m is your mass and is the acceleration due to gravity, downward
- The normal reaction exerted by the chair on you, , acting upward
Your body is in equilibrium (it doesn't move), this means that the two forces balance each other, therefore:
2)
We can now apply Newton's second law of motion to this situation; this law states that the net force acting on a body is equal to the product between its mass and its acceleration. Mathematically,
where
is the net force
m is the mass
a is the acceleration
In this situation, the net force is
So the equation becomes
However, we observe that your body is at rest; therefore, the acceleration is zero:
a = 0
And therefore,

The statements which best describe the properties of tsunami waves are these: 1. THEY HAVE LONG WAVELENGTH.
2. THEY TRAVEL AT VERY HIGH SPEED.
Tsunami typically occur as a result of sudden displacement of gigantic water masses which erupted due to earthquake that occur on the sea bed. One peculiar characteristic of tsunami is the very wide distances between its wavelengths. A tsunami is a very long wavelength waves of water, its wavelength is much more greater than that of ordinary wave and can be as much as 300 kilometer.
Wavelength is refers to the distance between two identical points on a wave, that is, between wave crests or wave troughs.
Tsunami also travels at very high speed; it can travel for a long period of time at high speed without losing much energy.
