Answer:
Id say C
Explanation:
The hypotenuse for c is up and to the right so the unit vectors show that
You use the equation Velocity = Acceleration X Time. 4x4=16m/s.
The car travels 18m in 3 seconds.
<span>In the desert environment the chemical weathering of rocks is generally reduced because there is a lack of rain, in which most chemical weathering is caused by. No rain, no chemicals, no chemical weathering.</span>
Height (y) = 36t - 16t^2, where t = time in seconds (s).
Our height (y) after 1s = 36(1) - 16(1)^2
y = 36 - 16 = 20 ft
So it reached a height of 20 ft during that 1 second, which means that at that 1 second it had a velocity of 20ft/s, since v = d(distance)/t = 20ft/1s
It comes from the sun, and then it is converted to energy/electricity (by solar panels)
