Answer:
Explanation:
Given:
Angular speed 
Radius of the solid sphere = R
Radius of the spherical shell, R' = 5.8R
now the initial moment of inertia i.e the moment of inertia of the solid sphere is given as:
where, M is the mass of the solid sphere
Now, the final moment of inertia i.e the moment of inertia of the spherical shell is given as:
or
or
Now applying the concept of conservation of angular momentum
we get
substituting the values, we get
or
The initial acceleration of the wishbone is 13.1 m/s².

Acceleration:</h3>
This can be defined as the rate of change of velocity. The S.I unit of acceleration is m/s²
To calculate the acceleration of the wishbone, we use the formula below.
⇒ Formula:
- F' = ma........................... equation 1
⇒ Where:
- F' = Net force between Kevin and Gamal
- m = mass of the wishbone
- a = acceleration of the wishbone
⇒ make a the subject of the equation
- a = F'/m....................... Equation 2
From the question,
⇒ Given:
- F' = 0.17 N
- m = 13 g = 0.013 kg
⇒ Substitute these values into equation 2.
- a = 0.17/0.013
- a = 13.1 m/s²
Hence, The initial acceleration of the wishbone is 13.1 m/s².

SI Units are based on meters, kilograms, seconds, amperes, kelvins, candelas, and moles, together with a set of prefixes to indicate multiplication or division by a power of ten.
There are seven SI base units, which are:
m - Meter - Length.
s - Second - Time.
mol/Mole - Amount of Substance.
A - Ampere - Electric Current.
K - Kelvin - Temperature.
cd - Candela - Luminous Intensity.
kg - Kilogram - Mass.
I think that the delivered units are how they are used such as watts which are equal to one joule per second. Others are “ergs per second (erg/s), horsepower (hp), metric horsepower (Pferdestärke (PS) or cheval vapeur (CV)), and foot-pounds per minute.”
So, SI base units are the basic units of things such as length or temperature. This would mean that the delivered units are the specific units per something like miles per hour.
