The statements that describe a benefit of the scientific method are as follows:
- It gives scientists a standardized way to approach a problem.
- It reduces bias and judgment from personal experiences.
- It gives scientists a common vocabulary for sharing information.
Thus, the correct options are B, C, and D.
<h3>What is the Scientific method?</h3>
The scientific method may be defined as a strategy of research in which a problem is recognized, relevant data is collected, a conjecture is composed of this data, and the assumption is empirically tested to determine the outcome of particular research.
The scientific method never explains or provides an answer to any question immediately because it consists of a scripted format with certain parameters.
The scientific method uses the identical vocabulary for sharing information with one another in particular terminology.
Therefore, it is well described above.

Answer: On the basis of speed they are all equivalent.
Yellow light = Fm radio wave = Green light = X-ray = AM radio wave = Infrared wave
Explanation:
Yellow light, Fm radio wave, Green light ,X-ray, AM radio wave and Infrared wave are all electromagnetic waves, and all electromagnetic waves move at the same vacuum speed which is the speed of light and is approximately 3.0x10^8 m/s.
They only differ in wavelength and frequency
c = λf
c (speed of light) = λ (wavelength) x f (frequency)
Therefore; on the basis of speed they are all equivalent.
Yellow light = Fm radio wave = Green light = X-ray = AM radio wave = Infrared wave
Answer:
As b ∝ (L/r²) and
the distance of the sun from the earth is 0.00001581 light years
and
the distance of the Sirius from the earth is 8.6 light years
hence,
the Sun appear brighter in the sky
Explanation:
The brightness (b) is directly proportional to the Luminosity of the star (L) and inversely proportional to the square of the distance between the star and the observer (r).
thus, mathematically,
b ∝ (L/r²)
now,
given
L for sirius is 23 times more than the sun i.e 23L
now,
the distance of the sun from the earth is 0.00001581 light years
and
the distance of the Sirius from the earth is 8.6 light years
thus,
using the the relation between conclude that the value of brightness for the Sirius comes very very low as compared to the value for brightness for the Sun.
hence, the sun appears brighter
Answer:
The energy may be carried in the form of (1) radiation, where energy travels in the form of light, and (2) convection, where energy is carried by physical motion of upwelling solar gas.
Explanation:
Explanation :
Work is done when a force is applied to create a displacement on an object.
Thus, the work done depends on the two factors i.e.
(1) Applied force (F)
(2) Distance or displacement (d)
Mathematically, work done is 
It also depends on the angle between the force and the displacement.
For example,
A person carries a weight of 20 kg and lifts it on his head 1.5 m above the surface. So, the work done by him on the luggage will be:
or
So, 
Hence, the work done by him on the luggage is 294 Joules.
