Answer:
Best at conductioning heat- Solid
Explanation:
<u><em>In order for heat to conduct it has to pass from particle to particle.</em></u>
A solid has particles closely compacted so the heat is able to tranfer quickly from particle to particle.
A liquid has isn't as compacted it actually has enough space to slide over each other
A gas has very far apart particles and takes heat longer to transfer from one particle to another.
The ball rises for v/g seconds; which equals 14.7/9.8=1.5 seconds . After this time, it’s height will be:
h(t)=g/2(1.5)²+14.7(1.5)
=-4.9 x 2.25 + 22.05
=11.025m
The ball then falls for 49+11.025=60.025m, which takes:
g/2t²=60.025
t²=12.25
t=3.5 secs
Total time: 1.5+3.5=5 seconds
Answer:
Explanation:
Pressure due to fluid is directly proportional to the depth of fluid, density of the fluid and the value of acceleration due to gravity.
P = h d g
Where, h is the depth, d be the density and g be the acceleration due to gravity.
If we talk about teh atmospheric pressure, the density of air goes on decreasing as we go up and up. o we cannot say that it is directly depends only on the depth of air, it also depends on the changing density of air.
B. I belive :)
Hopes this helps
