Answer:
My Take on this
The height of the wall can be related with the Horizontal distance traveled by the equation of the trajectory
y=xtan∆ - gx²(1+tan²∆)/(2u²)
The wall is at distance x1
So thats the horizontal distance we'll use... We need to find its corresponding vertical distance "y"
So
Applying the formula
∆=45°
x=x1
g=9.8ms-²
u=velocity of projection
Substituting
y= x1tan45 - 9.8x1²[1+(tan²45)]/2u²
tan45°=1
y= x1 -4.9x²(1 +1)/u
y= x1 - 4.9x²•2/u²
y= x1 - 9.8x²/u².
Answer:
A. Tropical
Explanation:
Although the climate varies over several environmental factors like: land industrialization, environmental issues, and increased pollution.
Answer: retrograde motion
Retrograde motion is an apparent change in the movement of the planet through the sky. It isn't real in that the planet doesn't physically start moving backwards in its orbit. It just appears to do so because of the relative positions of the planet and Earth and how they're moving around the Sun.
By replacing the year with the Page number. The author should already know background information from either the title or the intro paragraph. Good luck!
