Answer: The hexagon will rotate onto itself at 60°.
Step-by-step explanation:
A hexagon is a regular polygon with six sides) having all its sides and all its angles are equal.
For a regular polygon , Order of rotation of the figure = Number of sides .
i.e. Order of rotation for hexagon = 6
Let be the angle at which hexagon rotate onto itself, then we have
[∵One complete rotation=
]
Hence, The hexagon will rotate onto itself at 60°.

Answer:
The average acceleration of the cyclist was 0.6 m/s².
Step-by-step explanation:
Acceleration:
The rate change of velocity per unit time is call the acceleration of the object.
u= initial velocity
v= final velocity
t= time taken change of velocity.
During the final 5 seconds of a race cyclist increased her velocity from 4m/s to 7 m/s
Here v= 7 m/s and u=4 m/s t=5 seconds
=0.6 m/s²
The average acceleration of the cyclist was 0.6 m/s².
