4- We measured the rockets range using a measuring tape. 5- Record the rockets range on the “varying wing size “ complete the data sheet, including calculating the average range for each wing size. 6- Analyze the data generated from the launches and write a conclusion explaning how the difference in wing size affects the rocket that achieved the greatest range. Data table – Size ~ Wingspan ~ Launch Rocket A- Small ~ 2mm ~ 533 Rocket B- Medium ~ 4mm ~ 376 Rocket C- Large ~ 5mm ~
Chapter 17 Vocabulary AP CHEMISTRY 1. Electromagnetic radiation: radiant energy that exhibits wave-like behavior and travels through space at the speed of light in a vacuum 2. Wavelength: the distance between two consecutive peaks or troughs in a wave 3. Frequency: the number of waves (cycles) per second that pass a given point in space 4. Planck's constant: the constant relating the change in energy for a system to the frequency of the electromagnatic radiation absorbed or emitted, equal to 6.626 X 10^-34 J 5.
An 1894 article proposed the idea of a fully metal aircraft, and in 1895, he turned his eyes toward settling space. In 1903, his manuscript "Exploration of the World Space with Reaction Machines" was published in Nauchnoe Obozrenie magazine. This and his follow-up articles are regarded as the world's first scientifically viable proposals to explore outer space with rockets. Tsiolkovsky's rockets were fuelled by a mixture of liquid hydrogen and liquid oxygen, the same mix used on the space shuttle, though hydrogen had only been liquefied for the first time in 1898. His manuscript included the equation now named for the scientist.
What is the energy of a photon with a frequency of 6·1014 Hz? Answer | | 4·10-20 J | | | 4·10-19 J | | | 4 J | | | 40 J | 1 points Question 6 1. Which of the following statements (related to the photoelectric effect) is FALSE? Answer | | There is a minimum amount of energy which is necessary to remove an electron from the surface. | | | The energy of a single photoelectron depends only on the frequency of the incident light.
This field is said to be active and frequently interrelating with the solar wind and channelling plasma into Mercury’s surface from the sun. The chemicals captured from the solar wind include Hydrogen and Helium, which help create Mercury’s extremely thin atmosphere. Scientists would argue that there is ‘no’ atmosphere on Mercury at all. The little amount of gas found on Mercury is trillions of times thinner than the gasses found on earth, and would not be able to be detected without exceptionally sensitive equipment. Although very thin, Mercury’s atmosphere is made up of trace amounts of gasses including 42% Oxygen, 29% Sodium, 22% Hydrogen, 6% Helium, and 0.5% Potassium.
The consequence is that only special values of radius and energy are allowed. The mathematical appendix explains how to calculate these values. According to classical electrodynamics, a charge, which is subject to centripetal acceleration on a circular orbit, should continuously radiate electromagnetic waves. Thus, because of the loss of energy, the electron should spiral into the nucleus very soon. By contrast, an electron in Bohr's model emits no energy, as long as its energy has one of the above-mentioned values.

BRM 5- Confirm Zero Purpose- Confirm 300m zero at ranges 200m and 300m, and allows shooter to see the effects of wind and gravity on their bullet. Note- If crosswind exceed 5mph, KD zeroing should not be attempted. ACTION: Confirm Zero for M16 Series Rifle CONDITIONS: Day; KD range with crosswind of 5mph or less; M16 rifle; KD targets at 200m/300m; 2 magazines; 40 rounds 5.56mm, ACU w/soft cap STANDARDS: Confirm zero with 300m zero by firing 1 set of 20 rounds at 200m. 5-round shot group to obtain 8 out of 10 rounds—within a 12 inch circle. 1 set of 20 rounds at 300m using 5-round shot groups to obtain 6 out of 10 rounds within 19-inch circle.
His space flight idea was came up at that time. In 1883, Konstantin Tsiolkovsky finished his first treatise “Free space” which mentioned rocket must use jet propulsion. And then his article “The Exploration of Cosmic Space by Means of Reaction Devices” is the first academic treatise on rocketry. He said the horizontal speed required for a minimal orbit around the Earth is 8,000 m/s, this can be achieved by liquid fuel rocket whit liquid oxygen and liquid hydrogen. He also provided Tsiolkovsky rocket equation.
The Geology of the Moon Approximately 4.5 billion years ago a large asteroid struck Earth and thus resulted in the Moon. This impact theory suggests that the collision ejected raw materials which in time became the Moon. With the Moon having no significant atmosphere, it can reserve a good record of the impact history. This information can provide geologists with clues to the history of the Earth. The crust of the Moon is composed of a variation of primary elements, including uranium, oxygen, thorium, potassium, silicon, magnesium, iron, titanium, calcium, aluminum and hydrogen.
