Question: Three forces of magnitudes F1=4.0N, F2=6.0N, and F3=8.0N are applied to a block of mass m=2.0kg, initially at rest, at angles shown on the diagram. (Figure 1) In this problem, you will …

I have a large file (3.5G) that I'm trying to import using data.table::fread. It was originally created from an rpt file that was opened as text and saved as a CSV. This has worked fine with smal...

Question: Calculate the net torque about point O for the two forces applied as in the figure (Figure 1). The rod and both forces are in the plane of the page. Take positive torques to be counterclockwise.

The problem with your regex is the ^ character which means that your regex will only look at the start of the string for the NULL character. Take it off and your code will work just fine.

Question: Three forces, F1 = 20.0 N,f2 = 40.0 N, and F3 = 10.0 N act on an object with a mass of 2.00 kg which can move along a frictionless inclined plane as shown in the figure. The questions refer to …

I've got a PHP script that generates a business card template from details entered on the website. We've recently decided to add QR Code vCards to the business cards as an easy way to save contact...

To analyze the motion of an object undergoing damped vibration A 50.0-g object moves on the end of a spring (with spring constant k =25.0N/m ). It is released with an initial displacement of 0.300 m . A …

This is a continuation of my previous question here. I learned how to validate if the relationship holds for 3n2 − 100n + 6 = O(n2), because I choose c = 3 and 3n2 > 3n2 − 100n + 6; specific...

A box of weight w=2.0N accelerates down a rough plane that is inclined at an angle 30 degrees above the horizontal, as shown (Figure 6) . The normal force acting on the box has a magnitude n=1.7N, …

In some cases when you want to fill the null values from the previous non-null value, you can use fills functions. q)tbl:flip`a`b!(2;0N)#10?0N 0N 0N,til 3 a b --- 2 1 ...
