Answer:
Bottom of the circle.
Explanation:
At the top of the circle the tension and the weight contribute on being the centripetal force, at the middle of the circle only the tension contributes on being the centripetal force (the weight being perpendicular to it), while <u>at the bottom</u> of the circle the tension contributes on being the centripetal force (as always) <em>but the weight against to it</em>, so here is where the tension must be greater to allow the same centripetal force as the other cases, thus here is where the string will break.
They're most likely to be used in a house because if you turn on a switch in ur house the rest of them stay off they don't turn on
2000J
Explanation:
Given parameters:
Extension = 0.5m
Spring constant = 16000N/m
Unknown:
Energy stored in the bow string = ?
Solution:
The energy stored in a bow string is an elastic potential energy.
It can be calculated using the expression below;
Elastic energy = 
K e²
Where k is the spring constant
e is the extension
Input the parameters;
Elastic energy = K e²
= x 16000 x 0.5²
= 2000J

Answer: Option (a) is the correct answer.
Explanation:
Global Positioning Systems (GPS) is a system which uses a network of satellites to construct maps. So, that it would be easy to trace location of a person, or to reach over a certain place.
It helps an individual by showing the route of destination wherever he/she wants to reach along with the total time to reach over the place.
Thus, GPS can determine the elevation of a given area and also it can determine latitude and longitude of a given area. As each GPS satellite broadcasts with a high power, narrow bandwidth, down link signal which can be received by our small hand held receiver antenna called mobile phone.
A GPS cannot determine the composition of soil on mountain ranges.
Thus, we can conclude that out of the given options, GPS can determine the composition of soil on mountain ranges is not true about the Global Positioning Systems (GPS).
