The molecules of cold water have less energy and are moving slower than the one with hot water
Answer:
The answer is the Earth is tilted as the Earth makes its journey for the year around the Sun.
In general the earth is tilted at angle of 23.5 degrees from vertical axis. So that the Earth always pointing to one side as it revolves around the Sun. This causes varying amounts of Sun light around the Earth during the years gives us seasons.
So here we conclude that the axis of the Earth is most important thing, why the seasons occur.
Tilt:
Whenever the Earth lean towards the Sun, summer season occurs and lean away from the Sun winter season occurs. In between these two spring and Autumn occurs.
Answer:
Spring's displacement, x = -0.04 meters.
Explanation:
Let the spring's displacement be x.
Given the following data;
Mass of each shrew, m = 2.0 g to kilograms = 2/1000 = 0.002 kg
Number of shrews, n = 49
Spring constant, k = 24 N/m
We know that acceleration due to gravity, g is equal to 9.8 m/s².
To find the spring's displacement;
At equilibrium position:
Fnet = Felastic + Fg = 0
But, Felastic = -kx
Total mass, Mt = nm
Fg = -Mt = -nmg
-kx -nmg = 0
Rearranging, we have;
kx = -nmg
Making x the subject of formula, we have;
Substituting into the formula, we have;
x = -0.04 m
Therefore, the spring's displacement is -0.04 meters.
Answer:
<em>The</em><em> cliff is 74.4m</em>.
Explanation:
<em>The</em><em> </em><em>reading</em><em> </em><em>above</em><em> </em><em>clearly</em><em> state</em><em> </em><em>that</em><em> </em><em>a</em><em> </em><em>ball </em><em>is </em><em>dropped</em><em> </em><em>straight</em><em> </em><em>down</em><em> </em><em>with</em><em> </em><em> the</em><em> </em><em>speed</em><em> of</em><em> </em><em>9</em><em>.</em><em>3</em><em>m</em><em>/</em><em>s </em><em>and</em><em> </em><em>hit </em><em>the</em><em> </em><em>ground</em><em> </em><em>exactly</em><em> </em><em>at </em><em>a </em><em>time</em><em> of</em><em> </em><em>8</em><em>.</em><em>0</em><em>s</em><em> </em><em>after</em><em> </em><em>you</em><em> </em><em>released</em><em> it</em><em>.</em><em> </em><em>And </em><em>it</em><em> </em><em>is </em><em> </em><em>asking </em><em>for</em><em> the</em><em> </em><em>distance</em><em> of</em><em> the</em><em> </em><em>cliff</em><em>.</em>
<em>In </em><em>speed</em><em> formula</em><em> </em><em>make</em><em> </em><em>distance</em><em> the</em><em> </em><em>subject.</em>
<em>Therefore</em><em> </em><em>Distance</em><em> </em><em>=</em><em> </em><em>speed</em><em> </em><em>×</em><em> </em><em>time</em>
<em>Distance</em><em> </em><em>=</em><em> </em><em>9</em><em>.</em><em>3</em><em>m</em><em>l</em><em>s</em><em> </em><em>×</em><em> </em><em>8</em><em>.</em><em>0</em><em>s</em><em> </em><em>=</em><em> </em><em>7</em><em>4</em><em>.</em><em>4</em><em>m</em>
<em>Therefore</em><em> the</em><em> </em><em>c</em><em>l</em><em>i</em><em>f</em><em>f </em><em>is </em><em>7</em><em>4</em><em>.</em><em>4</em><em>m</em><em>.</em>
Answer:
I'm not sure if I have the right words for it, but it is most likely that all three rays will form a larger inverted image after they pass through the lens because the arrow is outside the focal point. The image will be outside of F2, like the arrow is outside of F1.
Explanation:
Due to the shape of the lens in the diagram, you can imagine 3 lines branching out from point Q. I've made a digital sketch about what will happen as they pass through. It's a little crude, but it still works. I hope this was helpful.
