begin our exploration of wave interference‚ consider two pulses of the same amplitude traveling in different directions along the same medium. Let’s suppose that each displaced upward 1 unit at its crest and has the shape of a sine wave. As the sine pulses move towards each other‚ there will eventually be a moment in time when they are completely overlapped. At that moment‚ the resulting shape of the medium would be an upward displaced sine pulse with an amplitude of 2 units. The diagrams below depict

"Those Winter Sundays" by Robert Hayden is a poem about a how the author is recalling how his father would wake up early on Sundays‚ a day which is usually a reserved as a day of rest by many‚ to fix a fire for his family.

It also describes a home that isn’t very warm in feelings as well as the title" Those Winter Sundays" The author describes the

very less as compared to that of conventional welding process. The mode of welding process is governed by the process parameters like laser energy‚ pulse duration‚ pulse frequency‚ power and welding speed. This paper aimed at to examine the influence of welding speed and power on weld bead geometry and performance parameters such as duty cycle‚ pulse overlap‚ energy density and bead diameter. In this contest‚ first experiment is conducted on austenitic 304L stainless steel sheet by varying the

lab‚ we will put blackworms into the Nicotine to look at the differences in pulse rates when compared to a control. The proper name for blackworms is Lumbriculus Variegatus‚ they are freshwater worms most commonly found in North America and Europe. The blood in blackworms circulates from the dorsal blood vessel toward the head through a series of rhythmic contractions. A common pulse rate for the blackworm is 7 to 8 pulse/minute. Hypothesis- If a stimulant increases heart rate‚ then when the Lumbriculus
