White raven [17]

Answer:

The more negative in content a schema is, the more likely it is to be accessible.    

Explanation:

A schema is an already existing mental framework which are developed in an individuals memory based on past experiences and they are very useful in the organization and storage of new information.

Schemas are accessible if they are related to our current goals or information, for example if a recent information is given about your friend, it will trigger or help you access the existing schema about him.

Priming also stimulates existing schemas about a topic or object of discuss.

Lastly, schemas can be assessed due to an individuals past experience, For example, an individual who has had an accident before will easily access the schema relating to that information.

A velodrome is built for use in the Olympics. The radius of curvature of the surface is 20.0 m. At what angle should the surface
kati45 [8]

Answer:\theta =57.37^{\circ}

Explanation:

Given

Radius of curvature=20 m

Speed of cyclist=17.5 m/s

we know that velocity during a turn is given by

v=\sqrt{\frac{rg\left (tan\theta +\mu_s\right )}{1-\mu_stan\theta }}

where v=speed

r=radius  of curvature

\theta=angle of banking

\mu_s=coefficient of friction

g=acceleration due to gravity

here \mu_s=0

thus

v=\sqrt{rgtan\theta }

\tan\theta =\frac{v^2}{rg}

tan\theta =\frac{17.5^2}{20\times 9.8}=1.562

\theta =57.37^{\circ}
