Answer:
4. Becomes softer as temperature rises
Explanation:
An amorphous solid is any noncrystalline solid in which the atoms and molecules are not organized in a definite lattice pattern. Such solids include glass, plastic, and gel. Solids and liquids are both forms of condensed matter; both are composed of atoms in close proximity to each other.

The magnitude of the centripetal acceleration of the car as it goes round the curve is 4.8 m/s²
<h3>Circular motion</h3>
From the question, we are to determine the magnitude of the centripetal acceleration. 
Centripetal acceleration can be calculated by using the formula

Where  is the centripetal acceleration
 is the centripetal acceleration 
 is the velocity
 is the velocity 
and  is the radius
 is the radius 
From the given information

and 
Therefore, 



Hence, the magnitude of the centripetal acceleration of the car as it goes round the curve is 4.8 m/s²
