The density of the substance is obtained by dividing its mass by its volume. Density is an intensive property which means that its value does not depend on the amount of substance and will always stay the same for same conditions.
d = 84.7 g / 46.7 cm³ = 7.75 g / x cm³
The value of x is approximately 4.27 cm³.
Answer:
the answer is calcium....
Answer:
C)The side that the charge is on, the top.
Explanation:
As we know that
1)More flux is possible, when the field is perpendicular to the cross sectional area.
2)Electrical field lines are more power full in this side because the charge is near to the top side.
3)Those sides are electric field parallel to area that sides have minimum flux.
So
The side that the charge is on, the top ,have least flux traverse.
Option C is correct.
Answer:
Speed of second car will be 57.17 m/sec
Explanation:
We have given lead car travels = 44 laps
1 laps = 1.34 km = 1340 m
So total distance = 1340×44 = 58960 m
Speed of lead car = 55.9 m/sec
We know that 
As the second car is 1 lap behind so distance traveled by second car = 45×1340 = 60300 m
So speed of second car will be
