= 2^-16 * 3^10 * 3^-8 * 3^-12 * 2^28
= 2^(-16 + 28) * 3^(10 - 8 - 12)
= 2^12 * 3^-10
= 2^12 / 3^10
9.2 (b) is the answer hope this helped!
Answer:
Step-by-step explanation:
First, the need to determine if the statements are true or false.
1) January is the first month of the year. (This statement is true)
2) December is the last month of the year. (This statement is also true)
With this in mind we can determine that what will illustrate the truth value would be:
T T -> T
In other words, since the first statement is true and the second statement is also true then conjunction of both statements would be true.
The moment of inertia of a spherical shell is I = mr²
If two spheres have the same moment of inertia, then
I₁ = I₂
m₁(r₁)² = m₂(r₂)²
Solve for the second mass:
m₂ = m₁ (r₁/r₂)²
Given m₁ = 1 kg, r₁ = 2 m, r₂ = 1m,
m₂ = (1 kg) (2 m / 1 m)² = 4 kg
