Answer:
The least efficient light bulb is the first one (25 W - 210 Lumen)
Explanation:
Efficiency can be defined as what you want to obtain over what you need to produce it. In this case Eff= Wattage / Lumen. For each light bulb, their efficiency is: 8.4 / 11.12 / 15.7 Lum/W
Both are temples designed to inspire reflection, meditative thought and are places of significant art and design. The Ryoanji garden uses asymmetry, spacial composition, minimalism and little color that arranges three small islands in a perfectly kept graveled garden with a prominent cherry blossom; the stained glass window at Chartres Cathedral, however, uses light, complicated symmetrical patterns, figuration, lots of color on the two-dimensional form of the glass.
Answer:
Wave speed = 50 m
Explanation:
Given
Wavelength = 5 m
Frequency = 10 Hz = 10
wave speed = ?
We know that all waves have same relationship among wavelength λ, frequency f and speed v , which is given by
v = fλ
Therefore wave speed = 10 x 5 m = 50 m
