How do different aspects and variables of energy (ex. intensity, distance from source, angle of incidence,...
5. By how many decibels do you reduce the sound intensity level due to a source of sound if you double your distance from it? Assume that the waves expand spherically. dB 6. The sound in a classroom is 63000 times as intense as the minimum threshold of hearing. What is the intensity level of this sound in decibels? dB
How are sound intensity, I and distance from the source, R related? Write hypotheses or claims about why each of these three relationships are linear or not linear: I vs. 1/R I vs. 1/R^2 I vs. R^2 Then, explain which one of these relationships is linear and why.
Show that the average intensity of the Sun's disk as seen from a distance D from the Sun's center is given by P/ (4π2T2), where the total radiant power output is P (joules per second) and the solar radius is r. For simplicity, assume that the Sun's intensity I is the same at all points on the visible disk. You will need to derive an exact expression for the solid angle subtended by the Sun's disk for R > r....
1. List at least two building energy rating systems and briefly explain from what aspects they evaluate the sustainability of a building 2. What is a net-zero energy building (NZEB)? 3. List at least eight technologies that can be applied to reduce energy consumptions in a NZEB 4. In your opinion, what are some main challenges for NZEB? 5. How do factors such as climates and building occupants affect the energy consumptions in a residential building? 6. Pick two NZEB...

Help please!!!! By how many decibels do you reduce the sound intensity level due to a source of sound if you double your distance from it? Assume that the waves expand spherically.
How do we find the slope distance, given the horizontal distance and the zenith angle? For example, From Station 40 to Station 41 HD=148.04 ft ZA=89.4013
11. How much energy from the Sun would the Curiosity Rover collect at Mars' average distance from the Sun of 1.52 AU, compared to how much that solar panel would collect at Earth? (Ignore any losses in energy due to the atmospheres of either body.) (The /is the division symbol.) a. 1/1.52 = 0.66) as much as received at Earth b. 1/(1.52 x 2) as much (= 0.33) as received at Earth c. 1/1.52 times as much (= 0.43) as...
What do you think? What do you think Compare the size, shape, energy, and distance from the nucleus between the Is and 2s orbitals. Explain. 2. Orbitals with the same energy are said to be degenerate. Which of the orbitals in beryllium are degenerate? 3. Compare the size, shape, and energy between the 2s and 2p orbitals. Explain. 4. How do the three 2p orbitals differ from one another? How are they similar?
Using a graph, illustrate how the number of species on an island can be affected by its size and distance from a mainland. Which two important demographic variables vary with the size of an island and its distance from a mainland? How might addition of a corridor between islands affect this relationship?
