Had to look for the options and here is my answer. What happens when the fluid discharge of an air-operated reciprocating pump is shut, this will cause the pump to OVERSTROKE. Overstroke happens when the engine is switching in a normally-closed manner.
Answer:
407 steps
Explanation:
From the question,
P = mgh/t........... Equation 1
Where P = power, m = mass, g = acceleration due to gravity, h = height, t = time.
Make h the subject of the equation
h = Pt/mg............. Equation 2
Given: P = 746 W, t = 1 minute = 60 seconds, m = 70 kg.
Constant: g = 9.8 m/s²
Substitute into equation 2
h = 746(60)/(70×9.8)
h = 44760/686
h = 65.25 m
h = 6525 cm
number of steps = 6525/16
number of steps = 407 steps

Using the formula
Answer:
2n t = m λ₀
, R = 0.240 mm
Explanation:
The interference by regency in thin films uses two rays mainly the one reflected on the surface and the one reflected on the inside of the film.
The ray that is reflected in the upper part of the film has a phase change of 180º since the ray stops from a medium with a low refractive index to one with a higher regrading index,
-This phase change is the introduction of a λ/2 change
-The ray passing through the film has a change in wavelength due to the refractive index of the medium
λ₀ = λ / n
Therefore Taking into account this fact the destructive interference expression introduces an integer phase change, then the extra distance 2t is
2 t = (m’+ ½ + ½) λ₀ / n
2t = (m’+1) λ₀ / n
m = m’+ 1
2n t = m λ₀
With m = 0, 1, 2, ...
Where t is the thickness of the film, n the refractive index of the medium, λ the wavelength
The thickness of a hair is the thickness of the film t
2R = t
R = t / 2
R = 0480/2
R = 0.240 mm
Answer:
Sample Response: If temperature and surface area increase, then the time it takes for sodium bicarbonate to completely dissolve will decrease, because increasing both factors increases the rate of a chemical reaction.
