Answer:
0.403ft/day
Explanation:
Area = 250 miles = 250 × 5280^2= 6.9696e9 ft
Rise per sec = (Flow in - Flow out)/Area of lake = (40,000 - 7,500)/(6.9696e9) = 4.663e-6ft/s
Therefore in 24 hours = 4.663e-6 × 3600 × 24 = 0.403ft/day
Answer:
Advertising campaign.
Explanation:
An advertising campaign is a group of advertisements, commercials, and related promotional materials and activities
, which are designed as part of a coordinated advertising plan to meet the specific goals of a company.
The purpose of the Advertising Campaign Event is to prepare an advertising campaign of any length for a real product, service, company, or business for a prospective client/advertiser.
The critical part of making an advertising campaign is determining a champion theme as it sets the tone for the individual advertisements and other forms of marketing communications that will be used.
The campaign theme is the central message that will be communicated in the promotional activities. The campaign themes are usually developed with the intention of being used for a substantial period but many of them are short lived due to factors such as being ineffective or market conditions and/or competition in the marketplace and marketing mix.
Answer:
a. radius = 0.0006m = 0.6mm and length =0.393m = 393mm
b. frequency =377.86Hz
Explanation:
Given:
mass of steel= 4g = 0.004kg
density of steel = 7890kg/m3
tensile stress of steel 7.0x10⁸
tension load =900N
from the density, we will calculate for the Volume of the steel string
density = mass/volume
volume = mass/density = 0.004/7890 = 5.07 x 10⁻⁷ m³
from the tensile stress will can get the maximum base Area of the string ,
tensile stress = load/area =
7x10⁸ = 900/A
A = 900/7x10⁸ = 1.29x10⁻⁶ m²
Area = πr²
area/pi = 4.105x10-7
radius = 0.0006m = 0.6mm
volume = Area x length
length = vol/area =(5.07 x 10⁻⁷ m³)/1.29x10⁻⁶ m² = 0.393m
b. the highest possible frequency is given by:
F = 
where T= tension, m=mass, L=length
F = 
= 297.04/0.786
frequency =377.86Hz
Hi!
To solve this multiply
7.5 x 8 = 60
The answer is C. 60 hours
Hope this helps! :)
