Answer:
The velocity is 7.0m/s
Explanation:
Given
Required
The bottom of the plane velocity
To do this, we apply the work-energy theorem which states that the energy at the highest point and at the lowest point are equal.
<u>At the highest point</u>
<u>At the lowest point</u>
Equate both values of energy
Take square roots of both sides
The velocity is 7.0m/s
Answer:
Good ozone is found in the stratosphere, far above the Earth's surface. At that height, it absorbs and scatters ultraviolet (UV) radiation from the Sun, particularly the most dangerous UV-B and UV-C forms. Ozone is the planet's natural sunscreen.
Explanation:
Answer:
1) The angle would be 150 degrees
a) coordinates would be ( , )
b) Trigonometric ratios:
sin:
cos:
tan:
csc: 2,
sec:
cot:
Explanation:
simplifys to which has a reference angle of . We can take the coordinates of and make the x value negative to find the correct coordiantes. Then, using those coordinates, plug the into the trigonomic equations.
For example, sin in opposite/hypotenuse. So sin = 1/2 divided by 1. Then you can find the rest of the equations that way.
cos= adjacent/hypotenuse
tan= sin/cos
csc= hypotenuse/opposite
sec= hypotenuse/adjacent
cot= cos/sin
Answer:
c
