Set it for two hours before dark. That gives all the normies plenty of time to do their shopping and spend days outside enjoying the summer. No pretty sunset fun for the normies until all those caught out and about giving the middle finger salute to civil society can be rounded up and mug-shotted and booked.

Only then were phonographs set up to record music on any scale, and then only as slot-machines for use in restaurants and bars. 6 The main serious application—from the viewpoint of the first manufacturers—was as a dictation machine, and this is how the early commercial phonograph was marketed, often with a typewriter at its side ... The dominant research program in high energy theoretical physics, string theory, has effectively given up on finding an explanation for why the particle masses are what they are. The current non-explanation is that they arise by accident, from the infinite landscape of theoretical possibilities. This is a cop out.

Consider a steel guitar string of initial length L = 1 m and cross-sectional area A = 0.5 mm 2. The Young's modulus of the steel is Y = 2*10 11 N/m 2. How much would such a string stretch under a tension of 1500 N? Solution: Reasoning: From the definition of Young's modulus Y = (F/A)/(∆L/L), we have ∆L = F*L/(Y*A). Details of the calculation:
Nov 26, 2020 · The two peaks at the beginning of November show two intents to charge the battery with grid power, because we initially assumed the problem was caused by a deteriorating battery. All the data above refer to a set-up consisting of a 50W solar panel with an energy storage capacity that is equivalent to that of an 86.4 Wh lead-acid battery.
That's a very valid point. My home system is currently well below audiophile standards, but my truck stereo is, IMnsHO, quite good (and currently being redesigned for the '00 competition year). Its set up for total sound quality, not pure bass. There are several pieces of music that I enjoy listening to at home that I just can't stand in the truck.

Let's say you keep two blocks on level ground and tie a string in between them. The tension in the string will be zero. This can be used to calculate the Tension. Take a string of length l. Suspend a known weight(say 1kg or 1kgf) to one end of the string and attach the other to a rigid body say the roof.
NOTE: I have assumed the connecting string is 2h long since there is no picture. If block 1 stays on the floor where it lands, then block 2 cannot go further than 2h away when it hits, unless you want to evaluate momentum of a connected system which can get real Look up "Atwood's machine".
The classical two-dimensional states are known to only exist up to a critical ('blow off') injection amplitude, but the three-dimensional solutions here appear possible for any injection velocity. We then go on to consider both the formation and stability of isolated streak structures embedded in a Blasius boundary layer, triggered by injection ...
We are going to have to set up two equations (assuming the mass of the pulley is negligible), one for each block. Let's pick the positive direction for acceleration to be with m 2 moving down, and m 1 moving up the plane. For m 2 we have the tension up (-), and the weight down (-). m 2 g = (2.7)(9.8 N/kg) = 26.46 N . Our equation is: 26.46 - T ...
