Answer:
Generally, when thermal energy is transferred to a material, the motion of its particles speeds up and its temperature increases. There are three methods of thermal energy transfer: conduction, convection, and radiation. ... Convection transfers thermal energy through the movement of fluids or gases in circulation cells.
Explanation:
Answer: E. Spatial association
Explanation:Spatial association can be defined as the degree to which things are similarly arranged in space. In Spatial association, analysis of the distribution pattern of two phenomena is done by map overlay. For example using spatial asssociation technique to analyze a trip distribution in an urban area.
Answer: (iii) the same about both ends
Explanation:
The moment of inertia is the sum of the square of the distance from the axis of massage and rotation of each length of the rod. The moment of inertia can be expressed as I = imiri2. The connection of the rod is the product of the moment length and distance (square), so it is the same at both ends.
Answer:
36 ml
Explanation:
The volume of the water was 50 ml without anything in it. When you put something in water, the amount of volume that it rises is the volume of the object put into it. It rose up to 86 ml.
86-50=36
36 ml
The relationship of the two is that, the sound intensity
is inversely proportional to the square of the distance of the source.
I α 1 / r^2
Where I = intensity and r = distance from source
From this, we can equate two conditions 1 and 2:
I1 / I2 = r2^2 / r1^2
So when r2 = 2 r1, the intensity becomes:
I1 / I2 = (2r1 / r1)^2
I1 / I2 = 4
I2 = I1 / 4
<span>So when we double the distance of the source, the
intensity of the sound reduces by a factor of 4 (divided by 4).</span>
