2. The emissive power varies with wavelength, the total spectral blackbody power does not. A. True B. False

A wind turbine with cut-in velocity of 8m/s and cut-out velocity of 30 m/s is installed at a
site with Weibull shape factor 2.4 and scale factor of 9.8 m/s. for how many hours in a day,
will the turbine generate power, estimate the probability of wind velocity to exceed 30 m/s.

What composition of lead-tin solder is the best choice for joining electronic components?

Why is this composition chosen?

what are the obstacles that might inhibit the collection and evaluation of Agile process metrics and production analysis matrices?

The creep rate of a viscoelastic material is measured under a load P at 25 °C and 100 °C, respectively. What material property causes the strain rate measured at 100 °C to be greater than that measured at 25 °C? According to what relationship does this material property change with temperature?

hydrofracking involves impregnating the shale with water (which contains some additives) at high pressure which opens cracks in the shale. explain why, to a natural gas company, hydrofracking might seem more feasible than drilling into the shale?

snowboards are typically made out of a thermosetting polymer (i.e. a three dimensionally connected glassy polymer). what type of mechanical behavior would you expect from that type of polymer and why do you suppose reinforcing the polymer with fiber would alleviate problems that might occur due to the mechanical behavior of the polymer?

how can I mount a 3" wheel on a motor with a 52mm dc motor

True False Question

1 Pneumatic energy is the power created by the release of water from a pond.

2 AD- Anaerobic Digester is the conversion of biodegradable waste matter into

compost in the absence of water.

3 Ocean Renewable Energy only includes Wave energy, current energy and

tidal energy.

4 Matching Renewable energy to aquaculture requires using rated kW and loads.

5 A Fish farm is sustainable when the aquaculture energy from the fish-fish

products is less than the energy used to power the farm.

6 For Desalination systems the main energy requirement is electricity.

7 For aquaculture farms, the two main energy areas are heating and electricity.

8 Offshore wind harvesting can be improved by using large floating wind turbines.

The acceleration of a rocket traveling upward is given by a = (8 + 0.02s) m/s2, where s is in meters.(Figure 1). Initially, v = 0 and s = 0 when t = 0.

Determine the time needed for the rocket to reach an altitude of s = 100 m .

Write a brief description of Hindrance to Oil and Gas Flow in Pipelines

1. A square-based pyramid has the volume V. If the vertical height is H (the normal distance from the square base to the point), write a MATLAB function that:

has V and H as input arguments

calculates the length of the side of the square (S)

has S as an output argument

Write MATLAB code that tests the function for the values:

V = 10 m³ and H = 2 m.

V = 2.586×10⁶ m³ and H = 146.6 m (the original dimensions of the Great Pyramid of Giza).

2. Repeat SPIDER 2 Q1, but write a function that accepts a year as an input argument and determines whether that year is a leap year. The output should be the variable extra_day, which should be 1 if the year is a leap year and 0 otherwise.

You must write a script file that thoroughly tests whether your function works correctly.
