Answer is Global Warming causes destruction of our ecosystem due to increased temperatures, drought, fire, weed and pest infestations, more intense storms, water shortages, melting ice caps and glaciers, air pollution.
Answer:

Explanation:
wavelength, λ = 2.5 m
speed, v = 13.8 m/s
Amplitude, A = 0.14 m
The general equation of the transverse harmonic wave which is travelling right is given by

where, Ф is phase
At t = 0, x = 0 , y = 0.14 m
0.14 = 0.14 Sin Ф
Ф = π/2
So, the equation is


Answer:
a. 
b. 
c. 
d. 
e. 
Explanation:
<u>Work and Kinetic Energy
</u>
When an object moves at a certain velocity v0 and changes it to v1, a change in its kinetic energy is achieved:

Knowing that

We have

The work done by the force who caused the change of velocity (acceleration) is

If we know the distance x traveled by the object, the work can also be calculated by

Being F the force responsible for the change of velocity
The 75 kg baseball player has an initial velocity of 6 m/s, then he slides and stops
a. Before the slide, his initial kinetic energy is



b. Once he reaches the base, the player is at rest, thus his final kinetic energy is


c. The change of kinetic energy is


d. The work done by friction to stop the player is


e. We compute the force of friction by using

and solving for x



The negative sign indicates the force is against movement

Full question:</u></h3>
Which statements describe the Mercalli scale? Check all that apply.
A. This scale measures seismic waves based on their size.
B. This scale rates an earthquake according to how much damage it causes.
C.This scale produces a single rating for earthquakes that reach the surface.
D. This scale uses Roman numerals to rank the damage caused by an earthquake.
E.This scale measures the magnitude of an earthquake based on the size of seismic waves.
<h3><u>
Answer:</u></h3>
The Mercalli scale : This scale rates an earthquake according to how much damage it causes and This scale uses Roman numerals to rank the damage caused by an earthquake.
<h3><u>
Explanation:</u></h3>
The Modified Mercalli scale is intended to illustrate the consequences of an earthquake, at a contracted station, on tangible characteristics, on modern fittings and human beings.
The Modified Mercalli Intensity value ascribed to a particular site subsequent an earthquake has an extra significant means of severity to the nonscientist than the magnitude because intensity assigns to the outcomes really encountered at that position. This scale is comprised of 12 growing levels of intensity, denoted by Roman numerals, arranging from gradual shaking to catastrophic impairment.
