Answer:
Given:
Initial velocity of the asteroid, v = 19.9 km/s = 19900 m/s
(since, 1km = 1000 m)
Final velocity of the asteroid, v' = - 18.3 km/s = -18300 m/s
time period, T = 1.97 years
Solution:
(a). Total change in velocity, :
= v' - v
= - 18300 - 19900 = - 38200 m
here, negative sign is indicative of the fact that the motion of the asteroid is in the downward direction.
(b) Asteroid's average acceleration, a:
a =
a =
a =
Here, the negative sign is the indication of deceleration of the asteroid in the downward direction.
It should be 12 N. the force of the book on the table should be the same as the force of the table on the book.
Depends on how steep the roof is , maybe the egg will just stay where it is but if the roof is more to the left it will fall to the left and same goes for right !
Answer:
1.18
Explanation:
The flow rate of blood is proportional to the fourth power of its radius as given the Poiseuille's law.
The law is :
It is given here that the flood flow rate is been reduced to half its normal value. Therefore,
So, for the radius and , the ratios of their flow rates are :
It is given that the flow rate is reduced to half. So we have,
or
So the radius changes by a factor of 1.18
