Answer:
s = 37.81 m
Explanation:
Given that,
Mass of an apple, m = 1.5 kg
The apple falls for 2.75s before striking the ground.
We need to find how far the apple dropped before hitting the ground. It means we need to find the distance covered. Using the second equation of motion to find it :
u is initial velocity, u = 0 (at rest)
So, Apple dropped 37.81 m before hitting the ground.
Answer:
What is it called when the right side of a design is reflected across a central axis and mirrored on the left side of the design?
Answer:
The work done on the gas is equal to the area under the curve pv diagram w = area of triangle = 1/2 (base)(height) = 1/2 (BC)(Ac) = 1/2 (3v - v)(3p - p) = 1/2 (9 vp - 3 vp - 3vp + vp) = 4 vp/2 W = 2 vp

The answer is so that everyone is measuring the same distance and counting that distance as the same everywhere. one example from real life why it is important to use standard units is the loss of the NASA mars orbiter. some people decided that the units were to be in metric and others thought that the units were in imperial (english) system. so the orbiter was lost.
let's eliminate some choices
A. to allow for consistientcy with measurement data:
not really, just make sure the instruments are accurate.
B. to use tools marked in customary units: this could be true because a custom is something that is accepted in a wide area and if it is standard, then it is customary so b is the answer
C. so they can keep measurement data secret: nope
D. to record with easier abbreviations: not really
the answer is B
