What is the primary disadvantage of outdoor advertising? it provides low flexibility it permits low repeat exposure it provides poor positional selectivity it provides little audience selectivity?

[ad_1]

Answered by answersmine AT 22/10/2019 – 05:18 AM

The primary disadvantage of outdoor advertising is that it provides little audience selectivity. It is because in outdoor advertising, they try to advertise or make known of their products by placing it on billboards, placing it on vehicles or any exterior places that could be placed on. What makes it have little audience selectivity is that the people who could only notice it is those who could be able to see the advertisement. With that, it makes only few people see it and does not target a lot of consumers.

Which of the following does OSHA require employers to do to reduce employee ‘s risk of exposure to bloodborne pathogens?

[ad_1]

Answer:

a) The time the police officer required to reach the motorist was 15 s.

b) The speed of the officer at the moment she overtakes the motorist is 30 m/s

c) The total distance traveled by the officer was 225 m.

Explanation:

The equations for the position and velocity of an object moving in a straight line are as follows:

x = x0 + v0 · t + 1/2 · a · t²

v = v0 + a · t

Where:

x = position at time t

x0 = initial position

v0 = initial velocity

t = time

a = acceleration

v = velocity at time t

a)When the officer reaches the motorist, the position of the motorist is the same as the position of the officer:

x motorist = x officer

Using the equation for the position:

x motirist = x0 + v · t (since a = 0).

x officer = x0 + v0 · t + 1/2 · a · t²

Let´s place our frame of reference at the point where the officer starts following the motorist so that x0 = 0 for both:

x motorist = x officer

x0 + v · t = x0 + v0 · t + 1/2 · a · t²      (the officer starts form rest, then, v0 = 0)

v · t = 1/2 · a · t²    

Solving for t:

2 v/a = t

t = 2 · 15.0 m/s/ 2.00 m/s² = 15 s

The time the police officer required to reach the motorist was 15 s.

b) Now, we can calculate the speed of the officer using the time calculated in a) and the  equation for velocity:

v = v0 + a · t

v = 0 m/s + 2.00 m/s² · 15 s

v = 30 m/s

The speed of the officer at the moment she overtakes the motorist is 30 m/s

c) Using the equation for the position, we can find the traveled distance in 15 s:

x = x0 + v0 · t + 1/2 · a · t²

x = 1/2 · 2.00 m/s² · (15s)² = 225 m

Carbo-loading is good for athletes that do aerobic activities that are NOT IMMEDIATE.  
                                         ———-Explanation———–
        This is because carbohydrates are polysaccharides, and they take longer to break down and turn into energy.  That’s why it is better to eat carbs the night before a big race/game/meet/regatta/competition, because then you get the benefits f the energy the following.  An example of this would be a runner.  The athlete may eat pizza Friday night for a Saturday track meet.  They wouldn’t feel energized Friday night, but the following day because their body had time to break down the carbs.  If you need quick energy(i.e. a couple hours before a race, then you should eat monosaccharides, such as a banana or an apple.  This is because monosaccharides take less time to break down, and therefore give you a quicker burst of energy.

Answer : Option B) Nonhuman life in an urban ecosystem differs from that in an undeveloped forest ecosystem.

Explanation : From the above information given, it can be simply concluded that humans have changed the environment around them. The human habitats are very different from the nonhuman life habitats.

The bacteria and fungi digests the organic part of the ecosystem. This is the primary function of the bacteria that is found in the food web.
