Explanation:
The vertical component the velocity of the projectile is 15 m/s x sin 30 = 7.5 m/s.
The body is accelarating downwards at 10 m/s^2.
This means that every second its upward velocity reduces by 10 m/s.
So if the body is travelling upwards at 7.5 m/s then how long does it take for the velocity to become 0?
(7.5 m/s) / (10 m/s^2) = 0.75 s
"Venus" has all that characteristics. It has <span>a rocky mantle, iron core and very dense atmosphere that is 96.5% poisonous carbon dioxide and 3.5% nitrogen
In short, Your Answer would be "Venus"

Answer:
You can compare and contrast the scientific method to the engineering design process
Explanation:
a. As sun peeks, it creates a straight line- sun to tree to shadow, angle=180°
b. During morning, the sun-tree-shadow changes from 180° to 90°, during noon, angle =90°.During sunset the angle changes from 90 to 0°.
c. Acute angles created in afternoon.
d. A right angle would be created at noon.
e. Obtuse angle would be created in morning.
f. Yes, a straight angle would be created at sunrise.
g. When sun is at mid-morning, the angle=45°+90°= 135°
That's a description of what makes the "Wankel engine" unique.
When it first came to the USA market, it came as the guts of a
new brand of car . . . the Mazda. I don't know if some, or all, or
none of today's Mazdas still use the Wankel 'rotary' engine.
