Answer:
It can change negative attitudes to positive ones
Explanation:
When an advert is done to target audience, some of the consumers may have developed a negative attitude towards the product or services before. However, when an advert is properly conveyed, there are chances that the consumers may change to have a positive attitude towards the advertised product or service. In conclusion, advertising can affect attitudes but cannot alter values or force people to do things they do not want to do or believe are wrong.
Answer:
The space station must turn at 0.24 rad/s to give the astronauts inside it apparent weights equal to their real weights at the earth’s surface.
Explanation:
In circular motion there’s always a radial acceleration that points toward the center of the circumference, so because the space station is spinning like a centrifuge it has a radial acceleration towards the center of the trajectory. To imitate the weight of the passengers on earth, they should turn the station in a way that the radial acceleration equals earth gravitational acceleration; this is:
And radial acceleration is also defined as:
with v the tangential velocity of the station and R the radius of the ring, solving for v:
We can find the angular velocity using the following equation:
That is the angular velocity the space station must turn.
The first one is d or the 4th answer choice and the second one is false. Hope this helps!
