image distance,di=10 cm
object distance,do=20cm
magnification, m=di/do
=10/20
=0.5
since the image is virtual, magnification is negative.
therefore m=-0.5
a self contained living thing is called adaptataion is true

Answer:
<em>the centripetal acceleration will now be four times its initial value</em>
Explanation:
v=velocity
a=centripetal acceleration
r=radius to the center
take note tat a centripetal force is the force tat is needed to keep a body moving along a circular path
centripetal force is given by f=mv^2/r
a=v^2/r
v=v
wen v
is doubled , we ave
2v
substituting into the previous equation of centripetal force
a=(
/r
a=4
^{2}/(r)
from the equation, is can be discovered that the centripetal acceleration will now be four times its initial value
