a balloon filled with some liquid is inflated and immersed underwater. the balloon remains at rest underwater. what would happen if the volume of the balloon decreased while the mass remained the same?

the balloon would remain at rest because the mass stays the same and so the forces on the balloon would not change.

the balloon would float and accelerate upwards because there would be a greater buoyant force acting on it than before.

the balloon would float and accelerate upwards because the smaller volume means it would take less force to make it float.

the balloon would sink and accelerate downwards because there would be a smaller buoyant force acting on it than before.

The balloon would sink and accelerate downwards because there would be a smaller buoyant force acting on it than before.

Explanation:

The density of a body is the ratio between its mass and its volume. A body float if its density is low and sink if its density is high.

As the ballon remain its mass but its volume decrease, the density will increase doing the ballon sink.

Thus, right answer is:

The balloon would sink and accelerate downwards because there would be a smaller buoyant force acting on it than before.

I hope it helps!

what is the general relationship between a galaxy's distance from earth and its speed?

the answer is:

the farther away a galaxy is from us, the faster it is moving away from us.

you need to take a look at the periodic system in order to sort these elements into pairs that would most likely exhibit similar chemical properties. first, you need to find elements that are found in the same group (groups are vertical in the periodic system), and then to see whether they have the same valence number. if they meet these criteria, they will have similar properties.

the first pair: ne (neon) and kr (krypton), are noble gases found in group 8

the second pair: li (lithium) and k (potassium), found in group 1

the third pair: s (sulfur) and te (tellurium), found in group 6
