Ответ:
force acting on small piston is 200 N
Explanation:
given data
cross-sectional area a = 2.0 cm² = 2 × m²
cross-sectional area a = 100 cm²= 100 × =m²
force f = 10,000 N
to find out
force acting on small piston
solution
we know that here pressure will be equal at all level in horizontal
so pressure at p1 = pressure p2
and pressure =
so =
put here value we get
=
solve it we get
force 1 = 200 N
so force acting on small piston is 200 N
Ответ:
In the near infrared (NIR) and the short-wave infrared (SWIR) spectrums, we measure the reflectivity of objects. Thus, using a specific lighting working in an active infrared spectrum, we can capture the rays reflected by the object and produce its reflectrogram.
Explanation:
hope it will help you have a great day bye and Mark brainlist if the answer is correct
