Technician a says that the water pump is a centripetal pump. technician b says that centripetal force is the outward force that

is exerted on a rotating object. who is correct?

<span>Technician A is correct about the water pump being a centripetal pump and the definition of the centripetal force given by technician B is wrong. The force that happens on a body moving in a circular path and move towards the centre to which the body is moving is called as centripetal force. So it’s not an outward force.</span>

maks197457 [2]

Answer:

∅=2021rad

Explanation:

Coherent light with wavelength 540 nm passes through narrow slits with a separation of 0.370 mm . At a distance from the slits which is large compared to their separation, what is the phase difference (in radians) i the light from the two slits at an angle of 28.0 ∘ from the centerline?

A wave is a disturbance which travels through a medium, it transfers energy without a permanent displacement of the medium itself. this is an example of light wave

using the formula below

∅=\frac{2\pi*d }{\beta } sin\alpha

the phase difference is given from the above

d= distance/separation of slits .00037m

\beta=wavelength

540*10^-9m

\alpha=angle of two slits  28.0 ∘

∅=(\frac{2\pi*0.00037 }{540*10^-9} sin 28

∅=2021rad

there are large bright fringes from the centre line

The mass of a glass beaker is known to be 24.2 g. Approximately 5 mL of water are added, and the mass of the beaker and water is
Kamila [148]

Answer: 2 significant figures in 6.4

Explanation:

Significant figures : The figures in a number which express the value -the magnitude of a quantity to a specific degree of accuracy is known as significant digits.

Rules for significant figures:

Digits from 1 to 9 are always significant and have infinite number of significant figures.

All non-zero numbers are always significant. For example: 654, 6.54 and 65.4 all have three significant figures.

All zero’s between integers are always significant. For example: 5005, 5.005 and 50.05 all have four significant figures.

All zero’s preceding the first integers are never significant. For example: 0.0078 has two significant figures.

All zero’s after the decimal point are always significant. For example: 4.500, 45.00 and 450.0 all have four significant figures.

Mass of beaker = 24.2 g

Mass of beaker + mass of water = 30.625 g

Mass of water = 30.625 - Mass of beaker = 30.625 - 24.2 = 6.4g

The rule apply for the addition and subtraction is :

The answer would contain same number of decimal places as there are in the least precise number present.

Thus there are 2 significant figures in mass of water which is 6.4 grams.

Explain the purpose of a three-valve manifold in closed tank level measurement installations.
mamaluj [8]

Answer:

A three valve manifold serves to protect the capsule from being exposed to pressures above the acceptable range and also enables transmitter isolation from the loop of the process

In closed tank level measurement installations the pressure of the gas if presence of gas on top of the liquid will need to be taken account by the use of a reference connection from the level transmitter to the tank top. The valve used in pressure equalization is kept close when the process system is operating normally.

In the event that the transmitter is removed or put into service, it is necessary to ensure that the gas phase which is at the higher pressure is does not over-range the Differential Pressure DP capsule
