Answer:
43.96 L
Explanation:
We are given that





We know that


Substitute the values


Hence, the volume of balloon at -14.8 degree Celsius=43.96 L
If both nuggets have the same mass and different densities then it can be concluded that the volume with the highest density is smaller.
For, so to speak, density is a relation of how much mass is there in a given volume. So the more the mass and the smaller the volume, the greater the density.
To verify this, let us calculate the volumes of iron pyrite and gold pyrite.
For the iron pyrite nugget:
density = mass / volume
volume = mass / density
volume = 50/5
volume = 10cm3
For the gold nugget:
volume = mass / density
volume = 50 / 19.3
volume = 2.59cm3
Therefore it is found that the nugget with the highest density (gold) is the one with the lowest volume.
Answer:
3469.788 m
Explanation:
t = Time taken
u = Initial velocity
v = Final velocity
s = Displacement
a = Acceleration
First rocket

Second rocket

When this will collide the total distance they would have covered would be 6000 m.


Hence at 13.72 seconds they will collide assuming they are launched at the same time.

The second rocket would have gone 3469.788 m when they collide
