Answer:cross-sectional area, and thus surface area, increases the amount of air resistance an object experiences
Explanation:
I think it would be yes because the drum is submerged in water and the water would slow the sound waves, making the sound softer. Right?
When you know both the speed and direction of an object’s motion, you know the velocity of an object. speed in a given direction is called velocity
hope this helps :)
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.
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).
