1 answer:

4 0

They utilize and apply the scientific method in gathering, interpreting and analyzing empirical evidence.

Empirical evidence, data or knowledge is an obtained set of facts or figures or existing and presenting data that was yielded during the process of experimentation or scientific discovery. These empirical data or evidence is further studied and investigated by the scientist in a formal scientific approach which follows the steps of observation, making a hypothesis, gathering data, interpreting data and evaluating the data. These steps of the scientific approach are vital in the course to explain and discuss the result and evidence obtained during the process.

Help asap!

patriot [66]

Answer:

220 V

Explanation:

$r_{1} = 20 ohm\\r_{2} = 30ohm\\r_{3} = 60ohm$

As the resistors are connected in series,

$R_{eq} = r_{1} +r_{2} +r_{3}$

= 20 + 30 + 60

= 110 ohms

V = IR

= 2 * 110

= 220 V

Hope it helps

The momentum of an object is determined to be 7.2 X 10-3 kg m/s. Express this quantity as provider or use any equivalent unit.

olasank [31]

There could be more than just one answer, since kilograms can be converted to grams, to miligrams, etc.

$7.2\frac{g.m}{s}$

$7200\frac{mg.m}{s}$

Why?

Let's remember some conversion factors to work with kilograms (kg)

$1kg=1000g=1x10^{3}g \\1kg=1,000,000mg=1x10^{6}mg \\1g=1000mg=1x10^{3}mg$

So, we are given the momentum:

$momentum=7.2x10^{-3} \frac{kg.m}{s}$

We can rewrite the units of the momentum (equivalent) as follow:

$momentum=7.2x10^{-3}kg \frac{m}{s}=7.2x10^{3} x10^{-3}g\frac{m}{s}=7.2\frac{g.m}{s}$

and

$momentum=7.2x10^{-3}kg \frac{m}{s}=7.2x10^{3} x10^{6}mg\frac{m}{s}=7.2x10^{3}\frac{mg.m}{s}$

Note: There could be more equivalent units for the momentum, in example, we could work with equivalent units for meters (distance) and seconds (time).

Have a nice day!

H2SO4 + NaOH > Na2SO4 + H2O. Balance this reaction if necessary. A) balanced B) 1,2,1,2 C) 1,2,1,4 D) 1,2,2,2

Aleksandr [31]

Answer:

B) 1,2,1,2

Explanation:

The balanced chemical equation will be;

H2SO4 + 2NaOH → Na2SO4 + 2H2O

The equation for the reaction is balanced by using coefficients; 1,2,1,2

According to the law of conservation of mass the mass of the reactants should be equal to the mass of the products.
For the law of conservation of mass to be obeyed, chemical equations must always be balanced.
