Answer:
A
Explanation:
Enjoyed for many years or decades.
Convex.
Concave curved inward (like how a cave foes in) and convex curves outward. Reflected and refracted do not apply to a lens.
The density is 4.76 gcm^-3
and if mass is in kg then density is equal to 4.76*10^-3
The tip of the fan moves through the outer side of the circle.
So it moves a distance of perimeter of circle in one revolution.
Perimeter of circle = 2r, where r is the radius of circle.
In this case radius of circular motion = 0.19 meter
So perimeter of circle = 2*0.19 = 0.38 = 1.194 m
So distance does the tip move in one revolution = 1.194 meter
In terms of physics, <span>acceleration, </span>a<span>, is the amount by which your velocity changes in a given amount of time. Given the initial and final velocities, </span>vi<span> and </span>vf<span>, and the initial and final times over which your speed changes, </span>ti <span>and </span>t<span>f.
That is all I can do to help, sorry, I haven't done this math a lot in my class yet...</span>
