Answer:

a = -4/5 m/s^2

Explanation:

Acceleration = change in velocity / time

change in velocity = final velocity - initial velocity

a = (20 m/s - 60 m/s) / 50 s

a = -40 m/s / 50 s

a = -4/5 m/s^2

hope this helps! <3

Answer:

<u>- 4/5 m/s^2 </u>

Explanation:

It is going from 60 to 20 m/s   so ACCELERATION is negative

   acceleration = change in velocity / time

                          = -40 m/s / 50 s =  <u>- 4/5 m/s^2 </u>

If an object is moving eastward and slowing down, then the direction of its acceleration vector is
iragen [17]
It would still be eastward because The direction of the velocity vector is always in the same direction as the direction which the object moves.

The velocity of blood flow is ________. A) in direct proportion to the total cross-sectional area of the blood vessels B) slower
Leto [7]

Answer:

Option (D)

Explanation:

The velocity at which blood flows in the blood vessels is inversely proportional to the total cross-sectional area of the blood vessels present in the body. This means that if the cross sectional area of the vessels low, then there will be high rate of blood flow, and vice versa. This blood flow is minimum in the case of capillaries, where it gets enough time for the exchanging of essential nutrients as well as gases.

Thus, the correct answer is option (D).
