<span>Answer: high heat capacity
Water is having a high heat capacity that makes it more stable because it needs much more energy to heat it up than other liquid. That makes a place with much water is a suitable and safer place for many organisms to grow. Water also can be used for temperature control like sweating in human.</span>
Answer:
D. Dylan is incorrect because a 90-degree launch angle results in the largest vertical range
Explanation:
Projectile is the motion of an object thrown into space. When an object is thrown into space, the only force which acts on it is the acceleration due to gravity.
An object thrown into space would reach maximum height (vertical range) if it is launched at an angle of 90 degrees. For maximum horizontal range, the object needs to be launched at an angle of 45 degrees.
Therefore Dylan is incorrect because a 90-degree launch angle results in the largest vertical range
Answer:
angle of twist of the bar is 3.32 ×
degree
Explanation:
given data
torque t = 571 lb-ft = 774.172 Nm
g = 18,431, 356 lb/ in² = 1.27 ×
Pa
d1 = 8.1 in = 0.205 m
d2 = 1.8 in = 0.045 m
L = 3.1 ft = 0.944 m
to find out
angle of twist of the bar
solution
first we get here polar moment that is express as
polar moment =
...........1
here do is outer diameter that is 0.205 m and d1 is inner diameter i.e 0.045 m
put here value we get
polar moment = ![\frac{\pi (0.205^4 - 0.045^4}{32}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Cpi%20%280.205%5E4%20-%200.045%5E4%7D%7B32%7D)
polar moment = 173.006 ×
now we get here angle that is
angle =
..............2
here T is torque and L is length and J is polar moment and G is share modulus
put these value in equation 2 we get
angle =
angle = 3.32 ×
degree
