The bodies of arthropods are supported, not by internal bones, but by a hardened exoskeleton<span> made of </span>chitin<span>, a substance produced by many non-arthropods as well. In arthropods, the nonliving exoskeleton is like a form-fitting suit of armor. It is produced by the "skin" and then hardens into a protective outer-covering.</span>
Answer:d
Explanation: oil would form droplets but only tiny ones because it’s surface tension is lower than that of water
Answer:
Explanation:
u = initial velocity = 20m/s
h = Height = 30m
Theta = 30°
g = acceleration due to gravity =9.8m/s^2
Time of flight (T) = total time taken by an object reach its maximum height and return to the ground.
T =( 2*u*sin(theta)) ÷g
T = (2*20*sin(30°))÷9.8
T = (40 * 0.5) ÷ 9.8
T = 20 ÷9.8
T = 2.04s
Velocity (v)
v = sqrt(2gh)
v = sqrt(2*9.8*30)
v = sqrt(588)
v = 24.25m/s
