1. applied research

Physics
1 answer:
ladessa [460]3 years ago
7 0

Answer:

Applied Research: It is a research conducted to find solutions for specific problems in a particular field of studies. Example, health effects on food that are genetically modified.

Basic research: It is basic research on any field to have a clear understanding of something from the existing knowledge. Example, the study on evolution of the living organisms.

Control:  To increase the reliability of the result the scientific experiments decrease the number of variables (depending factors) in the experiment.

Dependent variable: This is a variable that determines the outcome of the result of an experiment depending on the independent variables. For example,  stress influence the heart rate. Heart rate is a dependent variable.

Empirical evidence: It is the collection of scientific facts directly or indirectly. These facts support the scientific nature of the research. For example,  measuring temperature, water freezing at a particular temperature and pressure.

Hypothesis: It is an explanation or assumption of a phenomenon based on limited empirical evidence. This is the first step of the research.

Independent variable: This is a variable that the experimenter has control to change. For example, stress influence the heart rate. Stress is an independent variable.

wo fixed charges, A and B are located at x axis. A is at x = 0 m, B is at x = 4 m. QA = +4.0 μC and QB = -5.0 μC. Calculate the
lys-0071 [83]

Answer:

10250 N/C leftwards

Explanation:

QA = 4 micro Coulomb

QB = - 5 micro Coulomb

AP = 6 m

BP = 2 m

A is origin, B is at 4 m and P is at 6 m .

The electric field due to charge QA at P is EA rightwards

E_{A}=\frac{KQ_{A}}{AP^{2}}=\frac{9\times10^{9}\times4\times10^{-6}}{6^{2}}=1000 N/C (rightwards)

The electric field due to charge QB at P is EB leftwards

E_{B}=\frac{KQ_{B}}{BP^{2}}=\frac{9\times10^{9}\times5\times10^{-6}}{2^{2}}=11250 N/C (leftwards)

The resultant electric field at P due the charges is given by

E = EB - EA

E = 11250 - 1000 = 10250 N/C leftwards

Longitudinal sound waves cannot propagate through
strojnjashka [21]

Answer:

A vacuum

Explanation:

Sound waves are examples of mechanical waves. Mechanical waves are waves which are transmitted through the vibrations of the particles in a medium.

For example, sound waves in air consist of oscillations of the air particles, which vibrate back and forth (longitudinal wave) along the direction of propagation of the wave itself.

Given this definition of mechanical wave, we see that such a wave cannot propagate if there is no medium, because there are no particles that would oscillate. Therefore, among the choices given, the following one:

a vacuum

represent the only situation in which a sound wave cannot propagate through: in fact, there are no particles in a vacuum, so the oscillations cannot occur. In all other cases, instead, sound waves can propagate.
