Velocity answer. please explain steps​

Physics
1 answer:
spin [16.1K]3 years ago
5 0

As it is a position time graph

So, it's slope represents velocity

During last 15 seconds

it passes through (5,17) (20,2)

Slope = -15/15 = -1

So Velocity= -1 m/s

The Coriolis effect
alexandr402 [8]
The coriolis effect is due to the rotation of the earth. Look up youtube videos on it, its pretty cool. If we didn't have coriolis effect then hurricane's wouldn't even form! Also it affects the trajectory of hurricanes. If you look at a path a hurricane takes it always curves quite a bit. That's also because of the coriolis affect. Imagine you're on a merry go round or on some spinning disk. You throw a ball towards the center. The ball will seem to curve away from your target because you're spinning. Now its not because the ball curved and you missed, the ball goes in a straight line but because of the spinning the target you aimed at shifted.

Explain how birds, bats, insects, airplanes, rockets, and hot air balloons achieve their flight.
Oksi-84 [34.3K]

The birds, bats, insects, airplanes, rockets, and hot air balloons achieve their flight by creating high pressure below the aircraft and low pressure above it

<h3>What are living and non-living things?</h3>

They both consist of fundamentally simple building blocks. They are composed of substances or mass. Atmospheric and molecular building blocks make up the world.

In order to create high pressure below the aircraft and low pressure above it, airplanes employ specially built wings.

The wing receives sufficient airflow past it to counteract the weight and drag of the aircraft by utilizing a device to provide thrust, such as a propeller.

High pressure underneath the aircraft and low pressure above it is produced by specially constructed wings used by airplanes.

The wing receives enough airflow through it by the use of a thrust-generating device, like a propeller, to overcome the weight and drag of the aircraft.

The differences between how living and non-living things fly;

1. Moving both living and non-living objects consumes energy. Flying animals utilize their wings to create both lift and propulsion by moving them in relation to the body.

In contrast to most air vehicles, where the components that generate lift, wings, and thrust engines or propellers are distinct, the wings stay stationary.

Animal aviators like birds as well as natural parachuters like patagial as well as human inventions like aircraft as well as rockets that can power spacecraft and spaceplanes are just a few examples of the many things that can fly.

Hence, birds, bats, insects, airplanes, rockets, and hot air balloons achieve their flight by creating high pressure below the aircraft and low pressure above it
