The gravitational potential energy of Sara at the given height is 10594.8J.
Given the data in the question;
- Mass of Sara;

- Distance from ground;

- Acceleration due to gravity;

- Gravitational potential energy;

<h3>Gravitational Potential Energy</h3>
Gravitational potential energy is the potential energy an object with mass posessses relative to another object with mass due to gravity.
It is expressed as;

Where m is mass, h is height and g is acceleration due to gravity.
To determine the gravitational potential energy of Sara, we substitute our given values into the expression above.

Therefore, the gravitational potential energy of Sara at the given height is 10594.8J.

Answer:
D) Chisel
Explanation:
chisel-A metal tool with a sharpened, beveled edge that used to cut and shape wood, stone, or metal
Dual visual system:
Dual visual system is nothing but the different visual systems that our brain is meant to direct.
The two visual systems are
- Dorsal Stream
- Ventral Stream
Dorsal Stream:
Dorsal stream is mainly referred as a vision of action. This visual system is involved in moment by moment analysis. It is also known as where stream.
Ventral Stream:
Ventral stream is mainly referred to as the vision of perception. This visual system is meant to analyse and recognize shape and object etc. It is also known as What stream
Blindness:
Blindness is a defined as the lack of vision. Such type of vision loss can't be corrected either by contact lens or through glasses.
There are two type of blindness,
- Temporary Blindness
- Permanent Blindness
Temporary blindness is a condition where the vision of an individual vision is limited.
Permanent Blindness is a condition where an individual can't see anything even the light
