un serbatoio d'acqua di forma cilindrica è riempito con acqua dolce fino a un livello di 6,40 m calcola la pressione dell'acqua

alla profondità di 4,50 m e di 5,50 m dalla superficie dell'acqua

Per calcolare la pressione a una certa profondità, devi considerare la legge di Stevino:
<span>p = ρ · g · h

Tenendo conto che:
g = 9,81 m/s²
ρ = 1000 kg/m³

Troviamo:
p(h</span>₁) = ρ · g · h₁ = 1000 · 9,81 · 4,50 = 44145 Pa
p(h₂) = ρ · g · h₂ = 1000 · 9,81 · 5,50 = 53955 Pa

What body process converts physical energy to electrical energy?
nevsk [136]

The correct answer of the question given is D.

There are four body processes mentioned in the question are named as glycolysis,metabolism,photosynthesis and transduction.

Glycolysis is the metabolic process in which glucose is converted to pyruvic acid with the release of ATP and NADPH.

Metabolism is a chemical process which includes the formation or dissociation of  chemical compounds.

Photosynthesis is the biological process in which food is prepared by plants by absorbing minerals, water from soil and carbon dioxide from the atmosphere in the presence of radiant energy [sun light] .

Transduction: It is the biological process in which any external physical stimuli is received and relayed from one part of the body to another part.During this process energy i.e stimuli is converted into electro chemical stimuli.

when you drop a pebble from height h, it reaches the ground with kinetic energy k if there is no air resistance. from what heigh
marysya [2.9K]

Answer:

From the initial height h

Explanation:

When a material or substance is drop from a height h, it possesses potential energy, immediately it is dropped from that height, the potential energy is gradually converted to kinetic energy, it gets to a point where the potential energy equals the kinetic energy, as the material touches the ground, all potential energy has been converted to kinetic energy already

The amplitude of a lightly damped oscillator decreases by 3.0% during each cycle. what percentage of the mechanical energy of th
Zanzabum

E = ½KA^2 is the mechanical energy of any oscillator.  It is the sum of elastic potential energy and kinetic energy.  When amplitude A decreases by 3%, then

(E2-E1)/E1 = {½K(A2^2/A1^2) }/ ½K(A1^2)

= {(A2^2 – A1^2) / (A1^2)}

= 97^2 – 100^2/100^2

= 5.91% of the mechanical energy is lost each cycle.
