Answer:
Positive velocity and negative acceleration
Explanation:
An object moving in the positive direction has a positive velocity.
An object that's slowing down while moving in the positive direction has a negative acceleration.
As you approach the event horizon, your body would be pulled towards the black hole. It's a process called sphagettification.
Here's a quote from an article explaining this.
And gravity from the black hole is starting to pull on your feet more than your head. "The gravity wants to sort of stretch you in one direction and squeeze you in another," says Joe Polchinski.<span>

As for what you see, that is hard to explain without showing a video, at least for me, but you would see this black hole (ha) and whatever is outside starts to flatten and condense (from your POV) then you would fall into the black hole and then it's complete blackness.
But all of this is just educated guessing, and honestly, you'd be dead before anything would happen.
The upward force exerted by the elevator floor on the passenger is 7.6 times mass of the passenger.
<h3>What is force?</h3>
A force in physics is an effect that has the power to alter an object's motion. An object with mass can change its velocity, or accelerate, as a result of a force. An obvious way to describe force is as a push or a pull. A force is a vector quantity since it has both magnitude and direction.
Given in question elevator accelerates downwards with an acceleration of 1.2 m/s². There is acceleration due to gravity working downward which is 9.8 m/s².
So, net acceleration due to gravity is given as 9.8 - 1.2 = 7.6 m/s²
The upward force exerted by the elevator floor on the passenger is mass times acceleration, 7.6 times mass of passenger.

Answer:
Solving arithmetic problems or thinking logically.
Explanation:
The right cerebral hemisphere of the brain is responsible for coordinating reasoning and other task such as calculation, functional communication, which include problem solving, memory, and reasoning. Also, people with right hemisphere damage have difficulty changing their perception of a whole pertaining to an image and making critical decisions.
lets assume
L = length of the object = 5 cm
h = height of the object = 3 cm
w = width of the object = 2 cm
V = Volume of the object
Since the dimensions of object suggest it to be a cuboid
Volume of the object is given as
V = L w h
inserting the values
V = 5 x 3 x 2
V = 30 cm³
m = mass of the object given = 10 g
ρ = density of the object = ?
density of the object is given as
density of object = mass of object / Volume of object
ρ = m/V
inserting the values
ρ = 10/30
ρ = 0.33 g/cm³
