Answer:
zero
Explanation:
For a solid conducting sphere, charges are present on the surface of the sphere due to a phenomenon known as electrostatic sheilding. This affects the charge present in the body and makes it zero. However, the electrostatic potential appears to be equal to the whole present point that shows on the surface. The surface of a spherical conducting solid sphere is known as an equipotential surface. Thus, the potential difference between the two opposite points on the surface of the sphere will also be zero.
Answer:
Explanation:
velocity of the Escalators is given as 6 ft/s
now we know that Jane steps on parallel escalator after t = 5 s
so distance moved by John in same time interval is given as
now John and Jane will move towards each other with relative speed
Then will approach towards each other with this relative speed and meet after t = 15 s
so the distance moved by them
so total length of the escalators is given as
Answer:
groups on and two have the highest reactivity
Explanation:
the farther you move to the right the more reactive the elements get
Answer:
arithmetical multiplier for converting a quantity expressed in one set of units into an equivalent expressed in another.
Explanation:
An open system is a system that has external interactions.
a closed system is a physical system that does not allow certain types of transfers in our out of the system.
an isolated system obeys the conservation law that its total energy- mass stays constant.
