The formula to find the radius is R=V^2/A or Radius=Velocity^2/Acceleration so that means
R=V^2/A
10^2/5=R
100/5=R
R=20m
Answer:
that initially the weather vane was at rest, by this load that remained on the pole it would begin to move.
Explanation:
Let us carefully analyze the situation, when the bar is facing the index post a load of equal magnitude, but opposite sign on its surface, these two charges are in balance; When the hand touches the pole, it creates a path to the ground where the charges that were induced on the pole can be balanced with the charge coming from the ground, leaving a zero charge on the pole.
Now if the hand is removed, there can be no exchange of charges with the earth. When the bar is removed, the induced loads are redistributed in the post, but the excess loads that came from the earth that have the same value and are of a sign opposite to the induced ones remain, you want to sign that they are of the same sign as the charges of the bar.
In summary, after the process, the post has a load of equal magnitude and sign (negative) that of the bar.
If we assume that initially the weather vane was at rest, by this load that remained on the pole it would begin to move.
1) Thermal insulators are materials that slow down heat conductions, so they are used to prevent heat from going from one environment to another (for example, they are used in the walls of the houses, the keep the heat inside the house (in winter) or outside the house (in summer).
Examples of thermal insulators are fiberglass, plastic and air.
2) Thermal conductors are materials that allow rapid heat conduction, so they are used to transfer heat from one place to another.
Examples of thermal conductors are metals, for example silver and gold.
Answer:
Pluto's orbit brings it inside the orbit of <u>Neptune</u>.
Given:
Time taken for the travel: 40 mins=2400 secs
Velocity: 1.2m/s
Speed and velocity have the same magnitude. Speed is a scalar where as velocity is a vector quantity.
Distance traveled= speed x time.
Distance traveled: 1.2 x 2400=2880m
