B because B is showing that polarization would happen since hydrogen bubbles form that way.
It is boiling point for celsius
The distance travelled by the object in the time interval of 3 second is 44.15m
The airresistance would try to decrease the acceleration and thus would decrease the distance the ibject has fallen in 3 seconds.
Explanation:
The object is falling vertically down. Hence the acceleration would be replaced by the acceleration due to gravity "g".
We know that distance "s"= ut +1/2*g*t²
where u- initial velocity of the object
g- acceleration due to gravity= 9.81m/s²
t- time period
Since the object is falling from initial rest position hence u=0
thus the equation reduces to 1/2gt²
S=1/2*(9.81)(3)²
Thus the distance =44.145 m(approximately 44.15 m)
If a small amount of air resistance is present in between it would obstruct the falling of the object. hence, in turn, would oppose "g".
This opposition to "g" would decrease the acceleration and thus body would travel less distance in the same time frame i.e. 3 sec
Answer:
d
Explanation:
this is just common sense, why did you even need to ask?
Keona donates 1 ml of blood 473.176 times.
Each ml of blood has 1.06 gm of mass in it.
So the total mass of the blood is
(1.06 gm/ml) x (473.176 ml) = 501.566 grams
Rounded to the nearest hundredth, that's 501.57 grams.
