Answer:
25.8 rad/s
Explanation:
C = circumference of the hollow sphere = 0.749 m
r = radius of the sphere
Circumference of the hollow sphere is given as
C = 2π r
0.749 = 2 (3.14) r
r = 0.12 m
m = mass of the basketball = 0.624 kg
Moment of inertia of basketball is given as
I = 5.99 x 10⁻³ kg-m²
w = angular speed
KE = Kinetic energy of the ball = 1.99 J
Kinetic energy of the ball is given as
KE = (0.5) I w²
1.99 = (0.5) (5.99 x 10⁻³) w²
w = 25.8 rad/s
Answer: D. meter, kilometer
SI or "International System of Unit" is the unit that used in the international organization to make counting easier.
In this case, all of the options are base SI but if you compare them both they are a different unit that can't be converted each other. You can't convert gram into second.
Only option D. meter, kilometer is had the same unit that can be converted.
The correct answer would be A) the lenses of the eye change the size of images
Aluminium is ordinarily classified as a metal. It is lustrous, malleable and ductile, and has high electrical and thermal conductivity. Like most metals, it has a close-packed crystalline structure<span> and forms a cation in aqueous solution.</span>
