u right u right, curious what color shade that is
Answer:
Hey
Good question
How can we know if I planet was once inhabited by life? There diferent tequnecs for this. The first would be searching in the soil for fossilized microbes. in June of 19, 1976 Viking 1 was launched on its way to mars to began the search of life els wear. What this little lab did was drill a hole in the marsion terrain and take a sample of its soil to search for microbes or microbe fosles. Sadly it did not find anything. Other technics are to search for ruins on the planet or exoplanet. I do not have much to say about this method because it has never been used.
Hope it helped (i wrote all that).

Below is a picture of Carl Sagan next to the Viking Voyager 1. Obveosly this is just a modal. you could not breathe on mars.
Close proximity to the equator leads to very mild winters. Hotter climate year round and snow being extremely rare
Answer:
C. It triples in magnitude (PLATO)
2. The object's volume.
3. The density of the liquid.
Remember what the buoyant force is. It's the lifting force caused by the displacement of a fluid. I'm using the word fluid because it can be either a liquid or gas. For instance a helium balloon floats due to the buoyant force exceeding the mass of the balloon. So let's look at the options and see what's correct.
1. Object's mass
* This doesn't affect the buoyant force directly. It can have an effect if the object's mass is lower than the buoyant force being exerted. Think of a boat as an example. The boat is floating on the top of the water. If cargo is loaded into the boat, the boat sinks further into the water until the increased buoyant force matches the increased mass of the boat. But if the density of the object exceeds the density of the fluid, then increasing the mass of the object will not affect the buoyant force. So this is a bad choice.
2. The object's volume.
* Yes, this directly affects the buoyant force. So this is a good choice.
3. The density of the liquid.
* Yes, this directly affects the buoyant force. You can drop a piece of iron into water and it will sink. You could also drop that same piece of iron into mercury and it will float. The reason is that mercury has a much higher density than water. So this is a good choice.
4. Mass of the liquid
* No. Do not mistake mass for density. As a mental exercise, imagine the buoyant force on a small piece of metal dropped into a swimming pool. Now imagine the buoyant force on that same piece of metal dropped into a lake. In both cases, the buoyant force is the same, yet the lake has a far greater mass of water than the swimming pool. So this is a bad choice.
