Answer:
option D.
Explanation:
The correct answer is option D.
When an object is in equilibrium torque calculated at any point will be equal to zero.
An object is said to be in equilibrium net moment acting on the body should be equal to zero.
If the net moment on the object is not equal to zero then the object will rotate it will not be stable.
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
A. inelastic, since the girl moves in the same direction as the thrown ball
Answer:
A psychoanalyst would see the 4-year-old as having an unresolved conflict where the brain judges or evaluates how good or bad the darkness is, or the usefulness of sleeping in the dark at night based on a comparison, due to the child's exploration of the world around him. A psychoanalyst might see the child's refusal to sleep at night due to the dark as a fear created for instance when the child sleeps alone without the parent. This might change if the child sleeps at night beside the parent in the dark.
While behaviorists would look at how having previous negative experiences in the dark influences a child's behavior towards staying in the dark. This fear would be reinforced with more negative experiences in the dark such as having a bad nightmare whenever the child sleeps in the dark, a feeling of hearing, or seeing strange things while in the dark. These examples would have built a behavioral pattern where the child would be conditioned to respond fearfully to being in the dark.
