Answer:
Applied research
Explanation:
The process of developing a new vaccine involves the use of known scientific theories to address specific problems. Here, the outcome of several basic research are put into use to arrive at a targeted outcome. This outcome/product can be continuously modified (if it shows early promise) until the desired effect is achieved and if no "promise" is discovered at critical points of this research, work on this theory (for this research) is suspended another theory is pursued.
This process (described above) in which scientists continuously develop new treatments and/or vaccines and continuously subject it to testing until the desired effect is achieved can be referred to as Applied research.

The density of lead is 11.342 g/cm 3 . What would be the volume of a 200.0 g sample of this metal?
Answer:
The answer is
17.63 mLExplanation:
The volume of a substance when given the density and mass can be found by using the formula
[tex]volume = \frac{mass}{density} \\ [/tex]
From the question
mass of lead = 200 g
density = 11.342 g/cm³
It's volume is
[tex]volume = \frac{200}{11.342} \\ = 17.6335743...[/tex]
We have the final answer as
17.63 mLHope this helps you

Which phrase best describes an apple?
O homogeneous compound
O heterogeneous substance
O homogeneous mixture
O heterogeneous mixture
Answer:
an apple is best described as a heterogeneous mixture.
The phrase that best describes an apple is heterogenous mixture because it is made up of a different materials.
What is a mixture?A mixture is combination of different components that can be uniform or dispersed and homogenous or heterogenous. A homogenous mixture is the one in which the two or more components are dissolved together to form only one phase.
A heterogenous mixture is composed different phases with uniform or irregular arrangement of materials. Heterogenous mixtures look like a nonseparated random particles which are clearly distinguishable by eyes.
Apple is not a compound but is a mixture made up of different components such as water, pulp, seeds, pigments etc. and each forms their own phases.
Hence, Apple can be termed as a heterogenous mixture.

How do I convert 3.221×10^−3 mm to standard notation
Answer:
0.003221
Explanation:
When we multiply anything by 10 times a power, we follow the base 10 decimal system.
To convert 3.221 × 10⁻³ from scientific notation to standard notation, simply move the decimal place 3 places to the left:
3.221 × 10⁻³ = 0.003221

Predict the empirical formula of the ionic compound that forms from aluminum and oxygen.
A. AIO.
B. Al2O.
C. Al2O3.
D. Al3O2.
E. AlO2.
Answer:
A. AlO
Explanation:
The empirical formula of a compound is the simplest possible formula giving the ratio of atoms in a molecule of the compound.
We know that Aluminium forms [tex]Al^{3+}[/tex] and oxygen forms [tex]O^{2+}[/tex].
As such the formation of the ionic compound between a metal and non-metal results into [tex]Al_2O_3[/tex].
The empirical formula is as follows:
Element Aluminium Oxygen
% composition
by mass 26.98 16.0
mole ratio 26.98/26 16/16
= 1.04 = 1
divided by the
smallest number 1.04/1 1/1
1.04 1
The empirical formula is AlO

And experiment a student measures the speed of a toy car locations K through N as it rolls down a ramp based on the data collected in the table exclusion was shown by the student that the unbalanced forces acting on the toy car affect its average speed what reasoning lead to the interpretation of this data and conclusion
Answer:
B) The average speed of the car increases as distance traveled increases.
Explanation:
The unbalanced forces acting on the toy car affect its average speed, The average speed of the car increases as distance traveled increases. Therefore, option A is correct.
What do you mean by an average speed ?The term average speed is defined as the total distance traveled by the object in a particular time interval. The average speed is a scalar quantity. It is corresponded to the magnitude and does not have direction.
Average speed is calculated by dividing the total distance something travels by the total amount of time it spends traveling.
Average speed = Total distance covered / Total Time. The S.I. unit of speed is meter per second.
The unbalanced forces acting on the toy car impact its average speed, The average speed of the car increases as distance traveled increases.
Thus, option A is correct.

Two objects are moving in a straight line. One object has a faster speed than the other. They both have constant speeds (speed is not changing). Is either object accelerating?
Answer:
No
Explanation:
Acceleration refers to the increase in speed over time. Since both of the objects are moving at a constant speed (so the speed is not changing) neither are accelerating, because acceleration requires a positive change in speed.
They may be moving at different speeds, one faster than the other, but neither are changing their own speed so neither are accelerating.
