How do you find the volume of a doghouse? You can find volume by multiplying length times width time height. How do you find the volume of a hut? Multiply length x width x height The formula for the volume of the rectangular structure is L x W x H1. The example structure is 80 […]

Is a 10 mW laser dangerous? If you look at the dot from a 10,000 mW (10 W) visible laser within 1.8 feet (60 cm) for more than 10 seconds, this could potentially cause a retinal burn. In summary, looking at a diffuse line of red light from a Class IIIa (3R) laser, even for […]

How accurate is TLE? A value of 1 arcsec (2:8 10 4 deg), which equals in GEO 0.18 km, and is well below the intrinsic errors for GEO and HEO objects. The data in TLE format itself are limited to an accuracy of 35 m as explained previously. How accurate is SGP4? An Accuracy Analysis […]

What is the relationship between colonialism and exploitation? Exploitation colonialism is the national economic policy of conquering a country to exploit its population as labour and its natural resources as raw material. How did European exploit America? Europeans traded for slaves with the slave capturers of the local native African tribes in exchange for rum, […]

What are 3 differences between fixed and growth mindsets? “In a fixed mindset students believe their basic abilities, their intelligence, their talents, are just fixed traits. In a growth mindset students understand that their talents and abilities can be developed through effort, good teaching and persistence. What is a fixed mindset What is a growth […]

Why are continuously moving ecosystems unique? Rivers and streams are unique among ecosystems as they are continuously flushed with a fresh supply of water from upstream. Organisms must either swim continuously against the current or attach themselves to the bottom or some other fixed object (Figure 1). Lakes and ponds are classified based on their […]

What are the 8 levels of classification? The major levels of classification are: Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species. What are the 7 levels of taxonomy? There are seven main taxonomic ranks: kingdom, phylum or division, class, order, family, genus, species. In addition, domain (proposed by Carl Woese) is now widely used as […]

Are LED lights wired in series or parallel? Unlike LEDs that are wired in series, LEDs wired in parallel use one wire to connect all the positive electrodes of the LEDs your using to the positive wire of the power supply and use another wire to connect all the negative electrodes of the LEDs your […]

Why is green light not absorbed by plants? In conclusion, plant leaves are green because green light is less efficiently absorbed by chlorophylls a and b than red or blue light, and therefore green light has a higher probability to become diffusely reflected from cell walls than red or blue light. Chlorophylls do not reflect […]

What is use of diode? The most common function of a diode is to allow an electric current to pass in one direction (called the diode’s forward direction), while blocking it in the opposite direction (the reverse direction). Forms of rectifiers, diodes can be used for such tasks as extracting modulation from radio signals in […]
