Avg acceleration; under constant acceleration condition only; = Vf-Vi/time
a=Vf-Vi/time=(15m/s-6m/s)/(3s)=
(9m/s)/(3s)=3m/s^2
Hope this helps. Thanks.
Answer:
38,437.5
Explanation:
Density(d)= 102.5g/ml
Volume (v)=375ml
Mass(m) = ?
D =m/v
102.5= m/375
102.5*375=m
38,437.5=m
therefore Mass = 38,437.5g/ml.
Answer:
How Urgent are we talking?
Explanation:
Explanation:
12N by first law of newton is net force after colloision
Answer:
Natural frequencies of oscillation and typical earthquake frequencies should be different.
Damping on the structure should be large.
Explanation:
The natural frequency of the structure must be different from the typical earthquake frequency, the more different the better. This is because if both frequencies were the same or similar there is a risk that the building will <u>resonate </u>and collapse.
As for the damping, it must have a high value. This so that the building resists earthquakes better and prevents it from moving dangerously, thus damping on the structure should be large.
