Due to a malfunction in their computer system Artil Co. lost some vital
information. An example of this is the historical data of “Murudi
choc ball” (Artil’s elite product). The data recovered is as shown
below

March = 25
April = 27
May = 28
June = 34
July = 43
August = ( )

a) Determine the lost demand of “Murudi choc ball” for Aug. (Use
Simple Regression)

Why do so many people hold the view that the moon landing was faked? This has already been debunked numerous times and with factual data backing up the actual landing. I suspect when we finally launch the "planet finder" telescope, and can resolve the lander sitting on the surface------- folks will still contend that it is FAKED photo of the lander! Why?

Why would "intelligent" folks hold to this conspiracy theory?? .

First i would like to thank all that are helping me with this. I am not very bright when it comes to math.

Helen Weller invested $10,000 in an account that pays 12% simple interest. How much additional money must be invested in an account that pays 15% simple interest so that the total interest is equal to the interest on the two investmentsat the rate of 13%.

Alright well I have a lab due tomorrow, and there's one question I need help with. We rolled a ball bearing off a table and we need to answer some stuff about it. Alright I'll give you the data first. The velocity is .813 m/s. The table is 1m high. The ball landed 35.66cm's away from the table. I need to calculate the time it took the ball to fall from the edge of the table to the ground. Normally I don't post homework problems on Yahoo Answers, but I'm really having trouble with it. Thanks for the help!

Is friction always a net force? Can you think of an example where friction applies a force but does not result in accleration?

One end of a uniform meter stick is placed against a vertical wall . The other end is held by a lightweight cord that makes an angle with the stick. The coefficient of static friction between the end of the meter stick and the wall is 0.400.

a. What is the maximum value the angle can have if the stick is to remain in equilibrium?
b. Let the angle between the cord and the stick is = 16.0. A block of the same weight as the meter stick is suspended from the stick, as shown, at a distance from the wall. What is the minimum value of for which the stick will remain in equilibrium?
c. When = 16.0, how large must the coefficient of static friction be so that the block can be attached 15.0 from the left end of the stick without causing it to slip?
