What the core muscles do and why it's important to have a strong set of core muscles.

Answers

Answer 1

Answer:

Answer:

The core muscles stabilize and protect the spine. They help control all movements and make it possible for us humans to walk and stand up right. The core helps us transfer energy, shift our body weight and reach/move in different directions. It is important to have a strong set of core muscles because it makes everyday activities easier.

What is cell division? Like what does it mean? And also if you know, what does it do? Like what's the purpose of it. THANKSSS!!!!!

Answers

Cell division is when one cell splits in half to create two cells. This process is how cells reproduce.

Cells cannot just be created out of nothing. Most cells in living organisms multiply by Mitosis. This process starts with 1 cell and splits into 2 new cells. Firstly, a single cell increases in size. it then replicates and copies everything that is inside it, like DNA. the cell then splits in 2, creating 2 identical new cells.

a person pushing a stroller starts from rest, uniformly accelerating at a rate of 0.500 m/s2. What is the velocity of the stroller after it has traveled 4.75 m ?

Answers

Answer:

Approximately $2.18 m\cdot s^(-1)$ .

Explanation:

Consider one of the equations for constant acceleration ("SUVAT" equations)

$v^(2) - u^(2) = 2 \; a \cdot x$ ,

where

$v$ is the final velocity of the object,
$u$ is the initial velocity of the object,
$a$ is the acceleration of the object, and
$x$ is the distance that the object had traveled while its velocity changed from $u$ to $v$ .

Note that unlike other SUVAT equations, this one does not ask for the time required for the speed of the object to change from $u$ to $v$ . Since in this problem, time isn't given, this time-less equation would particular useful.

Here

$v$ the final velocity needs to be found.
$u = 0$ for the stroller started from rest.
$a =\rm 0.500 \;m \cdot s^(-2)$ is the acceleration of the stroller, and
$x = \rm 4.75\; m$ is the distance that the stroller traveled while its velocity changed from $u$ to $v$ .

Rearrange the equation to isolate the unknown, $v$ :

$v^(2) = u^(2) + 2 \; a \cdot x$ .

Make sure that all units are standard, so that the unit of the output will also be standard. Apply the equation:

$v = \sqrt{u^(2) + 2 \; a \cdot x} = √(0^2 + 2 * 0.500 * 4.75 )\approx \rm 2.18\; m\cdot s^(-1)$ .

Hence the final velocity will be approximately $\rm 2.18 m\cdot s^(-1)$ .

When applying the process of science which of theseis tested 1.a question, 2.an observation, 3.a conclusion, 4.a prediction

Answers

4. a prediction

Explanation:

According to the scientific method, an experiment is conducted to test a prediction/hypothesis stemming from the previous question.

A conclusion ... usually called a "theory" ... is tested. (3)

One great way to test a conclusion is to follow up on its predictions, and see how they turn out.
