Which of the following examples could be represented by this free body diagram? (check all that apply)a person skydiving with an open parachute an elevator accelerating as it goes up one floora rocket blasting offa ball accelerating as if falls off a cliff

Since in the given FBD we can see there are four forces on it

There are two horizontal forces on it which are equal and opposite to each other so it is balanced in horizontal direction

And as per given FBD we can also see there are two vertical forces in which vertically upward force will be more than the vertically downward force

So here we have to choose such situation where four forces are acting on it and out of which two horizontal forces must be balanced

so in case

1. An elevator accelerating upwards as it goes up

there is no horizontal force on it so this is not possible

2. A rocket blasting off

there is only gravitational forces on it as an external force so it is also not possible

3. ball accelerating as if falls off a cliff

there is again only gravitational force on it so it is also not possible

So the correct answer will be

A person skydiving with an open parachute  

scorpions are,

c.arachnids

  scorpions are animals in the order scorpiones, under the class arachnida, which makes them a distant cousin of spiders
