Answer:
2. [B] = [L]/[T] and [C] = [L]/[T]
Explanation:
I assume you mean this:
A = B² + 2B⁴/C²
Since you can't add numbers with different units (for example, you can't add seconds to meters), each term in the sum must have the same units as A.
B² = [L]²/[T]²
B = [L]/[T]
B⁴/C² = [L]²/[T]²
C²/B⁴ = [T]²/[L]²
C² = B⁴ [T]²/[L]²
C² = ([L]/[T])⁴ [T]²/[L]²
C² = [L]²/[T]²
C = [L]/[T]
Notice we ignore the 2 coefficient, which is unitless.
Answer:
Radians
Explanation:
The angular speed is a measure of the rotation speed of a body. It is defined as the angle rotated by a unit of time. Thus, It refers to the angular displacement per unit time and is designated by the Greek letter
. Its unit in the International System is radian per second (rad / s).
Answer:
5/9
Explanation:
First, find a common factor for 30 and 54.
30 and 54 can both be divided by 2.
30 divided by 2 = 15
54 divided by 2 = 27
So, your new fraction is 15/27.
However, don't stop there.
15 and 27 can both be divided by 3 as well.
15 divided by 3 = 5
27 divided by 3 = 9
So, your final answer is 5/9.
I hope this helps! :)
