Peak value is what we say to the maximum value of the signal..
or rms value..root mean square value
the average of the speed is 60
A circuit breaker is an automatic device for stopping the flow of current in an electric circuit as a safety measure.
A magnetosphere is the region surrounding the earth or another astronomical body in which its magnetic field is the predominant effective magnetic field.
Hope this helps!! All credit goes to Google though
Answer: Step Ladders
In general ladders are with inclined or vertical set of steps or rungs between two upright lengths of metal or wood. Ladders used for climbing up and down.
<u>Step ladders :</u>
It is a self supporting portable ladder, most commonly used in industries. Self-supporting means it does not need any support to lean. So this ladder can be used any where in the rooms. For example middle of the room where support is not available. Also this ladder is non-adjustable flat steps and hinged back.
here we have to calculate the net positive charge present on he surface of the conducting sphere.
as the sphere is a conducting one the,the charge will be stored on its surface.
though the charge is present at the surface,still it will behave just like the total charge is concentrated at the centre of the sphere.
the electric field at outside of the sphere is E=
as E= 
so V=
here V=27 volt,radius of sphere is 0.800 m and the point at which the potential is considered is at 1.20 m from th centre of the sphere.hence the point is at the outside of the sphere .
hence we have 27=
q=27×
coulomb
=3.6×
