Answer:
Explanation:
In this case the kinetic energy of the bike is converted into the heat energy between the area of contact of tyre and the road. This happens due to the work done by the frictional force between the surface to stop the relative motion between the road and the tyre.
Given:
- normal force on the rear tyre,
(as given in the question that the rear tyre supports half the combined weight of the bike and the rider.)
- distance dragged while stopping the tyre,
- coefficient of kinetic friction between the surfaces,
<u>Now, frictional force between the surfaces:</u>
<u>Now, the work done by the kinetic friction:</u>
According to the energy conservation this amount of energy is converted into thermal energy between the surfaces in contact, i.e. road and the tyre.
Given our understanding of Galactic space searches and techniques, we can confirm that the Inner Galactic Plane Survey conducted with the Allen Telescope Array is an example of a targeted search.
A targeted search is when a technique is used <u>not to sweep for general information</u>, but to identify points at which <em>specific processes </em><u>occur</u>. In the case of the Inner Galactic Plane Survey, the goal is to find points of star formations.
Therefore, we can say that the Inner Galactic Plane Survey conducted with the Allen Telescope Array in northern California is an example of a targeted search.

At a temperature of 298 K, the Henry's law constant is 0.00130 M/atm for oxygen. The solubility of oxygen in water 1.00 atm would be calculated as follows:
<span>S = (H) (Pgas) = 0.00130 M / atm x 0.21 atm = 0.000273 M
</span>
At 0.890 atm,
<span>S = (H)(Pgas) = 0.00130 M / atm x 0.1869 atm = 0.00024297 M</span>
<span>
If atmospheric pressure would suddenly change from 1.00 atm to 0.890 atm at the same temperature, the amount of oxygen that will be released from 3.30 L of water in an unsealed container would be as follows</span>
<span>
3.30 L x (0.000273 mol / L) = 0.0012012 mol</span>
3.30 L x (0.00024297 mol / L) = 0.001069068 mol
0.0012012 mol - 0.001069068 mol = 0.000132 mol
<span>Convection means the movement happens inside a fluid
by the cause of too much heat and lesser density to rise, and also the colder
cause denser materials to sink.
Thus, Solid cannot undergo convection because the molecules inside the solid
are closer and can hardly move unlike liquid.
So, when the temperature got hotter or colder, the molecules on solid will only
vibrate and not convert.
Therefore, this concludes that the solid do not undergo convection rather
conduction of heat.</span>
No it does not ...hope this helps
