the correct answer is B. 1.27
Mechanical advantage of a lever is simply the ratio of the effort arm to the load arm.Effort arm is the distance from the pivot to the point of application of force while load arm is the distance of the lord from the pivot.
therefore, in this question, the effort arm is 0.28m while the load arm is 0.22 m. MA is calculated as follows: MA=effort arm/load arm
=0.28m/0.22m=1.27
Answer:
Yes, Mirror are a surface that reflects light more perfectly than ordinary objects.
Explanation:
Liquid water because if it said very high then it would be water vapor but it didn’t say that so the answer is B liquid water
Answer:
Biomass-Total of mass of organisms in a given area/volume
Biofuel-A fuel directly from living matter.
Newton said . . . F = m a
Divide each side by m . . . a = F / m
Acceleration = (force) / (mass)
Acceleration = (145.O N) / (40.0 kg)
<em>Acceleration = 3.625 m/s²</em>
