1. Plastic surgery (Used mostly by both genders to fill in the missing spots they have on/in their body or increase the size or decrease depending on whatever you want the doctor to do for you)

2. Plastic water bottles (Normal containers that we should recycle more and also are used to hold/store our water in to hold it for use while we drink, like a mobile water fountain)

3. Plastic Trumpet (Used to show younger children how to play the real instrument, like a preview of it).

The ____ connects the left and right sides of the cerebrum
Fofino [41]

Answer:

The left and right hemispheres of the cerebrum are connected by the Corpus Collosum.

Explanation:

The corpus collosum is a thick band of neurons that divides the cerebral cortex lobes into the left and right hemisphere. The corpus callosum allows for both hemispheres to communicate and transfer information! The primary function of the corpus callosum is to integrate sensory, motor, and cognitive performance between the cerebral cortex.  

Ins severe cases of epileptic seizures, a corpus callosotomy is performed, which cuts the corpus callosum in half. This prevents the seizures from becoming more severe, and the brain can reprogram, through neuroplasticity.

Which has more gravitational potential energy—a book sitting on a desk or the same
nydimaria [60]

Answer:

The book sitting on the desk

Explanation:

The gravitational potential energy of an object is the energy possessed by the object due to its position relative to the ground.

It is calculated as:

GPE=mgh

where

m is the mass of the object

g is the acceleration due to gravity

h is the height of the object with respect to the ground

From the formula, we see that the GPE of an object is directly proportional to the heigth h: so, the higher the location of the object, the larger the GPE.

In this problem, we are comparing a book sitting on a desk and the same book sitting on the floor. In the two situations, the mass of the book is the same; however, in the first case, the value of the height is h, while in the second case, the value of h is lower (because the book is located at a lower height, being on the floor).

Therefore, we can conclude that the first book must have a larger GPE, since it has a larger value of h.

What is the SI unit for acceleration?
aivan3 [116]

Answer: m/s^2 (metre per second square)

Explanation:

Acceleration is the rate of change in velocity per unit time. The standard unit of measurement for acceleration is m/s^2 (metre per second square).

It can be derived from:

Acceleration = velocity / Time

Acceleration = (metre per second / second)

Acceleration = metre per second square.

In short form, it is written as m/s^2
