Answer:
8 Newton
Explanation:
Weight = force
then, given,
weight= 0.495 kg
force= 7.28 N
Now,
the total force acting on the bird = (Weight + force)N
=(0.495 + 7.28)N
=8N
hence, the total force acting on the bird is 8 N.
THE FORCE IS REMOVED BUT THE BODY DOES NOT RETURN TO ITS' ORIGINAL SHAPE (ALSO CALLED PERMANENT DEFORMATION)
Answer:
The centripetal acceleration of the car will be 12.32 m/s² .
Explanation:
Given that
radius ,R= 57 m
Velocity , V=26.5 m/s
We know that centripetal acceleration given as follows
Now by putting the values in the above equation we get
Therefore the centripetal acceleration of the car will be 12.32 m/s² .
Answer: poor construction of houses
Explanation:
Majority of the people that died in Iran were as a result of poor building methods coupled with the fact that there was lack of proper regulation.
California experienced a similar earthquake but due to safer construction methods, about three people died.
Due to population boom in Iran and house shortage, this resulted in builders building cheap houses which were not strong enough.
