15: Approximately it is 46.6%.
16: 7%(100%-65%-18%-10%)
Answer:
The answer is b.
Step-by-step explanation:
if you look up what a ray is, it will look like the description b has.
it would be 0, because in the origin equations, the d's cancel out since it's x-x, only 2 would be left, therefore the correct answer is A since 0+2=2
Answer:
Step-by-step explanation:
Given
When mass = 4kg; Acceleration = 15m/s²
Required
Determine the acceleration when mass = 10kg, provided force is constant;
Represent mass with m and acceleration with a
The question says there's an inverse variation between acceleration and mass; This is represented as thus;
Convert variation to equality
; Where F is the constant of variation (Force)
Make F the subject of formula;
When mass = 4kg; Acceleration = 15m/s²
When mass = 10kg; Substitute 60 for Force
Divide both sides by 10
<em>Hence, the acceleration is </em><em />
