To find the total number of miles traveled by a person, we add the distance that he has traveled: 3.0 + 5.00 + 4.000.
Now, to find the accurate number of significant figures when adding measurements, the basic rule for addition is to use the least number of decimal places when reporting the result.
Now, since 3.0 has the least number of decimal places, we report the sum with 1 decimal place and have 12.0 miles as the total distance traveled by the person to reach his destination.
Answer: 12.0 miles
Answer:
VR = 
Explanation:
Velocity ratio (VR) of a machine is a term that compares the distance moved by effort put into the machine to the distance moved by the load.
A wheel and axle is a device for lifting of a load through a height. It is made up of two circular parts called wheel and axle. Its velocity ratio (VR) can be determined by:
VR =
For a practical wheel and axle, the diameter of the wheel is greater than the diameter of the axle.
Answer:
prinsip bernoulli
Explanation:
Prinsip Bernoulli adalah sebuah istilah di dalam mekanika fluida yang menyatakan bahwa pada suatu aliran fluida, peningkatan pada kecepatan fluida akan menimbulkan penurunan tekanan pada aliran tersebut. Prinsip ini sebenarnya merupakan penyederhanaan dari Persamaan Bernoulli yang menyatakan bahwa jumlah energi pada suatu titik di dalam suatu aliran tertutup sama besarnya dengan jumlah energi di titik lain pada jalur aliran yang sama. Prinsip ini diambil dari nama ilmuwan Belanda/Swiss yang bernama Daniel Bernoulli.
Answer:
<h2>42.5 N</h2>
Explanation:
The force acting on an object given it's mass and acceleration can be found by using the formula
force = mass × acceleration
From the question we have
force = 50 × 0.85
We have the final answer as
<h3>42.5 N</h3>
Hope this helps you
The object will move in the direction of the applied force.
