F - False.
Its greatest kinetic energy is at the point of release.
It has the least kinetic energy, zero, at its highest point in its path.
Answer:
Explanation:
Earliest standards were dependent on a single frequency/channel to both send and receive. This shared medium creates the same problem as half-duplex coax cable. Because receivers had to wait for the signal before sending a response, this reduced the overall bandwidth.
Other factors affect wireless signal propagation, too, including RF interference, antenna choice, and obstacles such as walls, trees, and even weather (precipitation, for example).

Answer:
a) 
b) 
c) 
d) 
e) Since Dave starts from house and finally returns to the house so displacement is zero.
Explanation:
Given:
- distance between the house and the store,
- speed of driving from house to store,
- speed of driving back from store to house,
Since the store is located towards east from his house and the velocity in this direction is taken negative and contrary to this the velocity in the west direction is taken positive.
a)
time taken in reaching the store:
b)
Now the time taken in returning form the store:
therefore total time taken by the trip:
c)
the time taken by the trip in minutes:
d)
distance travelled in the whole trip:
e)
Since Dave starts from house and finally returns to the house so displacement is zero.
<span>A Conducting Sphere Is On Top Of An Insulating Stand. So A Negatively Charged Tube Is Brought Near The Neutral Sphere Then It Forces Electron Movement From The Left To The Right Side Of The Sphere. Once Touched By The Ground, The Electrons Leave The Sphere. When The Tube Is Moved Away, There's An Overall Positive Charge Left On The Sphere.</span>
