Answer:

b. they can be observed and measured

Explanation:

Matter is anything that has weight and occupy space. There are three states of matter namely Solid, liquid and gas.

The properties of matter are both physical and chemical in nature. Both properties can be measured and observed. Phhysical properties are anything that can be measured without changing the state of the matter. Example of physical properties includes mass, volume, length, color etc.

Chemical properties is another properties of matter. This is the ability of the states of matters to combine with other substance to form a new product for example, rusting of iron, formation of salt etc.

All this as discussed are both measurable and can be observed.

How do you determine the acceleration of an object?

Gelneren [198K]

Are you familiar with any basic calculus? If so, we can just look at this derivative and see what's happening with our units here..

$a = \frac{dv}{dt}$

Here it shows that acceleration is the derivative of velocity with respect to time. In other words, we can say that:

$a=\frac{\Delta v}{\Delta t}$

We can read that equation as: "acceleration is the change of velocity divided by the change in time (aka the time interval)."

If you're not familiar with calculus, we can use a simple equation of motion:

$v_f = v_i+at$

where:

vf = final velocity

vi = initial velocity

a = acceleration

t = observed time interval

We can rearrange this equation to find:

$a = \frac{v_f - v_i}{t}$

This is the same exact thing we wrote before!

Nuclear fusion and gravitational contraction

<span>constituent of star is hydrogen(including isotope) or helium. nuclear fission is almost impossible. D(deuterium; isotope of hydrogen) and T(tritium; also isotope of hydrogen) reacts and helium is formed. During this reaction, severe energy is generated. Heavier elements are formed and pulls each other. Gathered elements forms core of star. Gravity of the core prevents the gas to run away.</span>

A car traveling at 23 m/s starts to decelerate steadily. It comes to a complete stop in 5 seconds. What is its acceleration?

kykrilka [37]

We could determine the acceleration using this formula
$\boxed{a= \dfrac{v_{1}-v_{0}}{t} }$

Given from the question v₀ = 23 m/s, v₁ = 0 (the car stops), t = 5 s
plug in the numbers
$a= \dfrac{v_{1}-v_{0}}{t}$
$a= \dfrac{0-23}{5}$
$a= \dfrac{-23}{5}$
a = -4.6
The acceleration is -4.6 m/s²
