PHYSICS helppppp
a horizontal wire is stretched between two vertical poles. when a 12.0-N weight is suspended at its center, the wire sags until the angle between its halves is 110 degrees. what are the forces exerted by each half of the wire in supporting the weight? i don't really get th...

a 60 km/h wind is blowing in a direction 30 degrees north of east. a. what is the component of the velocity oriented to the east? b. what is the component of the velocity oriented to the north? The component east is 60cos30. For both a and b, draw a diagram with a horizontal l...

factoring
if the length of one side of a square is 1/2h, find the representation of the area. If a side of a square is s, the area is s squared. area of square is (length of side)^2. Substitute 1/2h for (length of side) and go from there.

PHYSICS!!!
how can i plot a v-t graph for this data and also account for the results and sources of error:if a ball starts from rest, and rolls down a .56m trackway, its final velocity is 1.10m/s, and the acceleration is 1.08m/s^2? HELP!!!!!!!im lost in it!!!!! The initial v was zero. Ma...

if the same ball rolls down from three different length trackways with a 20degrees elevation, its acceleration on the short-length trackway is 1.08m/s^2;its acceleration on the medium-length trackway is 1.79m/s^2;and its acceleration on the long-length trackway is 1.52m/s^2. h...

extrapolation is the process whereby we extend an established numerical relationship between two variables beyond the limits of our observed and recorded data. why extrapolation would not be useful and wise to use in force-elongation graph? In force-elongation, as one extropla...

the cables of a suspension bridge as well as the elements of many man-made structures are designed to behave elastically. can anyone briefly explain to me why it is absolutely necessary that such elements function elastically? Bridges and other man-made structures are subject ...
