To identify a pure liquid substance using the physical properties of solubility, density, and boiling point. The physical properties of a pure substance can be measured without changing the composition of the substance. In this experiment you will learn techniques for determining solubility, density, and boiling point.

How do I convert 498.82 cg to mg

mezya [45]

Answer:
498.82 cg is equivalent to 4988.2 mg

Explanation:
cg stands form centigrams
mg stands for milligrams

From the standards of conversion, to convert from centi to milli, we multiply the amount ny 10

This means that:
1 centigram = 10 milligram

To convert 498.82 cg to mg, all we have to do is cross multiplication as follows:
1 cg ..................> 10 mg
498.82 cg .........> ?? mg

498.82 cg = $\frac{498.82*10}{1}$ = 4988.2 mg

Hope this helps :)

A box slides down a frictionless ramp.if it starts at rest, what is it’s speed at the bottom?

zhenek [66]

8.854 m/s is the speed of the box after it reaches bottom of the ramp.

Explanation:

From the figure we came to know that height of the block is 4 m.

We know that,

Total "initial energy of an object" = Total "final energy of an object "

Total "initial energy of an object" is = "sum of potential energy" and "kinetic energy" of an object at its initial position.

$\text { "g" acceleration due to gravity is } 9.8 \mathrm{m} / \mathrm{s}^{2}$

$\text { Total initial energy }=\mathrm{m} \times \mathrm{g} \times \mathrm{h}_{\mathrm{i}}+\frac{1}{2} \mathrm{m} v_{i}^{2}$

Initial velocity is “0” as the object does not have starting speed

$\text { Height of the block where the object is placed initially }\left(h_{i}\right) \text { is } 4 \mathrm{m} \text { . }$

$\text { Total initial energy }=\mathrm{m} \times 9.8 \times 4+\frac{1}{2} \mathrm{m} 0^{2}$

Total initial energy = 39.2 × m

$\text { Total final energy }=\mathrm{m} \times \mathrm{g} \times \mathrm{h}_{\mathrm{f}}+\frac{1}{2} m v_{f}^{2}$

$\text { We need to find final velocity } v_f$

$\text { Height of the block where the object is travelled to bottom (h_) is } 0 \mathrm{m} \text { . }$

$\text { Total final energy }=\mathrm{m} \times 9.8 \times 0+\frac{1}{2} m v_{f}^{2}$

Now, Total initial energy of an object = Total final energy of an object

$39.2 \times \mathrm{m}=0.5 \mathrm{m} v_{f}^{2}$

$\frac{39.2}{0.5}=v_{f}^{2}$

$v_{f}^{2}=78.4$

$v_{f}=\sqrt{78.4}$

$v_{f}=8.854 \mathrm{m} / \mathrm{s}$

Final speed is 8.854 m/s.

Distance between bholu and golu house house 9 km . bholu has to attend golu birthday party at 7am . he started from his home at

navik [9.2K]

For the rest 3 km

Bholu need to run in 5 minutes so

He need to 3 × 1000 / 5 × 60 m/s

3000/ 300 = 10 m/s

So , his speed should be 1 m/s to reach in 5 minute

mark as brainliest 5 star

Why are the decomposers categorized as consumers? how do they differ from producers

QveST [7]

Hi! Decomposers (mainly soil bacterium, fungus, or invertebrate) are categorized as consumers due to the fact that they consume dead organic matter such as plants and animals. They differ from producers (green plants and some bacteria) because they do not produce their own food using photosynthesis or chemosythensis.
Hope this helped!
