emmainna [20.7K]3 years ago
3 0

Answer:

Her answer is not reliable.

Explanation:

Reliability and validity are two major concepts that are used to assess the standard and quality of response/research.

While validity of an instrument is the idea that the instrument measures what it intends to measure, reliability is all about consistency and whether or not results could be replicated.

While your friend's answer may be valid, it can't reliable because of the differences in her response within a short time.

How is the energy carried per photon of light related to the wavelength of the light?
AveGali [126]

The energy carried per photon of light is inversely proportional to the wavelength of the light

The "quantum of electromagnetic radiation" is called a photon. It is, thus, the tiniest and most basic particle of electromagnetic radiation. A photon is a stable particle that has no mass and no electric charge. The concept of wave-particle duality holds true for this particle.

The distance between the two crests or troughs of the light wave is known as the wavelength of light. It is represented by the greek letter lambda 'λ'

A quantity is inversely proportional if it decreases when the related quantity is increased or vice versa. For example, frequency is inversely proportional to wavelength

A hill is 132 m long and makes an angle of 12.0 degrees with the horizontal. As a 54 kg jogger runs up the hill, how much work d
TEA [102]

Answer:

14523.55J

Explanation:

The work done by the jogger against gravity is given by the following equation;

W=mgh.................(1)

where m is the mass, g is acceleration due to gravity taken as 9.8m/s^2 and h is the height of the hill.

Since the length of the hill is 132m and it is inclined at 12 degrees to the horizontal, the height is thus given as follows;

h=132sin12^o\\h=27.44m

Substituting this into equation (1) with all other necessary parameters, we obtain the following;

W=54*9.8*27.44\\W=14523.55J

If the elevation in reservoir b is 100m, what must the elevation in reservoir a be if thevolume flow rate through the cast-iron
Zinaida [17]

The elevation in reservoir  at  the rate of flow using is 03m/s  is 114m.

The Reynolds range is the ratio of inertial forces to viscous forces. The Reynolds variety is a dimensionless variety used to categorize the fluids structures in which the impact of viscosity is crucial in controlling the velocities or the flow sample of a fluid.

The reason of the Reynolds number is to get a few experience of the relationship in fluid glide between inertial forces (this is those that maintain going by using Newton's first law – an item in motion stays in movement) and viscous forces, this is people who cause the fluid to come back to a forestall because of the viscosity of the fluid.

calculation,

Let L = 100 m pipe

     L1 = 150 m pipe

H f = friction losses

Using Reynolds number, relative  roughness, friction co- effiicients and friction losses

Substitute the value in equation

Z = 110= 0.48= 3.54

Z = 114m

Therefore water surface elevation at reservoir  is 114 meter.
