The ratio of the rotational kinetic energy about the center of the sphere and the total kinetic energy of the sphere is 2/7.
<h3>What is the
rotational kinetic energy of a sphere?</h3>
The rotational kinetic energy of the sphere is directly proportional to the square of angular acceleration.

Where,
= rotational inertia of sphere = 2/5MR²
Where
is the mass of the sphere and
is the radius of the sphere,
ω = angular acceleration of sphere = V/R
Where
is the speed of the sphere.
So,
K = 1/2 × 2/5MR² × V²/R²
K = MV²/5
The translational kinetic energy of the sphere,

The total kinetic energy of the sphere,

So,

Thus the Ratio of rotational kinetic energy to total kinetic energy,

Therefore, the ratio of the rotational kinetic energy about the center of the sphere and the total kinetic energy of the sphere is 2/7.

Just multiply the "1.0 m/s" by ' 1 ' a few times. (Remember that a fraction with the same quantity on top and bottom is equal to ' 1 ' .)
(1.0 m/sec) · (1 km/1000 m) · (60 sec/min) · (60 min/hr) =
(1.0 · 60 · 60 / 1,000) (m · km · sec · min / sec · m · min · hr) =
(3,600 / 1,000) (km / hr) =
3.6 km/hr .
Answer:
a
0.57g
b
20.52
c
28.5
Explanation:
a
The bottle weighs 80g with tablets
If the bottle alone weighs 23g, the tablets weigh 57g
100 tablets weigh 57g, 1 tablet weighs 0.57g
b
0.57g is one tablet, so to achieve 36 tablets we must multiply by 36
0.57 multiplied by 36 is 20.52
c
To find 50 tablets we can use the same method we used before or a slightly faster method
100 tablets is 57g, so all we have to do is halve to find 50
57 divided by 2 is 28.5
