Which of the following terms represents the debate between genetic and environmental influences on behavior?
A.
stability versus change
B.
continuity versus stages
C.
nature versus nurture
D.
general versus multiple
Answer:
I believe it is nature vs nurture
Explanation:
The term that represents the debate between genetic and environmental influences on behavior is nature versus nurture. Thus, the correct option for this question is C.
What do you mean by Genetic influences?Genetic influences may be defined as the types of concerns that significantly deal with the behavioral and psychological characteristics of an individual which include their intellectual ability, personality, and risk for mental illness with respect to their genetic sequences.
When you talk about the debate between genetic and environmental influences on behavior, the term nature reflects the environmental aspect of the debate while the term nurture reflects the genetic aspects of the debate.
Therefore, nature versus nurture is the term that represents the debate between genetic and environmental influences on behavior. Thus, the correct option for this question is C.

Typically, people think of a lava flow when they think of volcanoes. However, some eruptions are mostly ash and steam released into the atmosphere. This type of volcanic eruption is blamed for causing what is referred to as a "Little Ice Age" starting in the 13th century. The ash and steam blocked the sun's rays causing extreme cold and agricultural difficulty which lead to massive decreases in populations.

What are the relationships between the different wave properties (frequency, wavelength, wave speed, period, amplitude)
Ex) As ___ increases, ___ increases/decreases/remains the same.
Answer:
As frequency (cycles per second) increases the wavelength decreases.
As frequency increases the period also decreases
If wave speed or velocity increases, so too does the frequency
Amplitude of a wave is totally independent of frequency, period etc. So it remains the same as frequency shifts. Like FM radio the amplitude remains the same as the frequency of the broadcast modulates.
Explanation:
F= 1/t Frequency is inversely proportional to time (wavelength)
Period is the time it takes for one wave cycle to complete Period is 1/f
++++++++++++++++++++++++++++++++++++
vw=λT Speed of propagation vw= wavelength x T time
vw=fλ Knowing frequency multiply times wavelength to get wave speed.
++++++++++++++++++++++++++++++++
Amplitude varies only as the energy applied varies. Like transmission power, in a 60 hz power feed the amplitude can be 120, 230, 460 volts (note these nominal amplitudes are RMS root mean squared or .707 of the peak of the waveform).

For a substance to change from a liquid to a solid, what must happen to its
particles?
O A. They must lose enough of their kinetic energy that their movement
is influenced by the attractions between them.
B. They must gain enough kinetic energy to allow them to move
freely while still being attracted to one another.
C. They must lose enough of their kinetic energy so that the
attractions between them hold in place as they vibrate.
D. They must gain enough kinetic energy to break out of their rigid
structure and move independently.
Answer:
C. They must lose enough of their kinetic energy so that the attractions between them hold in place as they vibrate.
Explanation:
The "kinetic energy" refers to the energy of an object when it is moving. This is directly proportional to the object's "thermal energy." If the kinetic energy of an object increases, the thermal energy increases and if the kinetic energy decreases, the object's thermal energy decreases as well.
Changing the phase of an object from liquid to solid means that the object will be subjected to low temperature. This means the thermal energy will decrease as well as the kinetic energy. This is known as "freezing." The object needs to lose enough kinetic energy. This results to its particles moving closer together in an attractive force.
So, this explains the answer.

B. Semiconductors reflect all forms of electromagnetic radiation.
C. Semiconductors serve as a source of electrons to form an electrical current.
D. Current flows from the positively charged semiconductor to the air above the glass covering
Two statements describe reasons a solar cell must contain semiconductors :
A. Semiconductors form a path for the electrons that are released by the photoelectric effect.
C. Semiconductors serve as a source of electrons to form an electrical current.
What is Photoelectric effect?Photoelectric effect, phenomenon in which electrically charged particles are released from or within a material when it absorbs electromagnetic radiation.
When the semiconductor is exposed to light, it absorbs energy and transfers it to the material, due to which energy reaches to negatively charged particle (electron), which allows the electron to flow in the material as electric current .
hence , correct option will be :
A. Semiconductors form a path for the electrons that are released by the photoelectric effect.
C. Semiconductors serve as a source of electrons to form an electrical current.

4. Vector A is 7.00 units in length and points along the positive x-axis. Vector B is 5.00 units in length and points along the negative x-axis. find the magnitude and direction of A+2B 1 point
Answer:
Since the two vectors form a right angle, no components need to be found for the resultant vector - we already have them!
Vector R's x-component = 3.00 units
Vector R's y-component = 4.00 units
To solve for the magnitude of the displacement, use the distance formula: Square Root of [(3)^2 + (4)^2], which equals 5 units.
To solve for the direction of the displacement, plug in -4 (remember where it was pointing) for y and 3 for x. Tan-1(-4/3) = -53.13°, or 53.13° south of east.Please Mark as Brilliant
The magnitude of vector C is |C| = 3 and It is directed along the negative x - axis.
What is vector quantity?
A vector quantity is a quantity with both magnitude and direction.
Given is vector A is 7.00 units in length and points along the positive x-axis. and vector B is 5.00 units in length and points along the negative x-axis.
Vector A = 7 a[x]
Vector B = - 5 a[x]
Therefore, the given expression to be evaluated is -
C = A + 2B
C = 7 a[x] + 2(- 5 a[x])
C = 7 a[x] - 10 a[x]
C = - 3 a[x]
So, the magnitude of vector C is -
|C| = 3
It is directed along the negative x - axis.
Therefore, the magnitude of vector C is |C| = 3 and It is directed along the negative x - axis.

hows a 170 g hamster sitting on an 830 g wedge-shaped block. The block, in turn, rests on a spring scale. An extra-fine lubricating oil having μs=μk=0 is sprayed on the top surface of the block, causing the hamster to slide down. Friction between the block and the scale is large enough that the block does not slip on the scale.
The complete question with the scale is missing, so i have attached it.
Answer:
930 g
Explanation:
The block surface is frictionless, therefore, the only force that can possibly be applied to the block from the hamster will be the normal force.
Now, the force of gravity on the hamster acts downward and equals mg. Hence, The normal component will be;
F_n = mgcosθ.
Now, if we Assume that the scale does not respond to horizontal force component, the downward component of the normal force will be expressed as;
F_d = F_n(cosθ)
The scale measures the downward component.
Earlier, we saw that; F_n = mgcosθ
Thus; F_d = mgcosθ × cosθ
F_d = mg(cos²θ)
Now, when the friction was high, the measurement of the scale was;
(m+ M)g
Where ;
m = mass of hamster
M = mass of block
Therefore, when the friction is removed the scale measurement is;
mgcos²θ + Mg or (mcos²θ + M)g
But this is in units of Newton's.
Thus;
Measurement in kg is;
(mcos²θ + M)
We are given;
m = 170 g = 0.17 kg
M = 830 g = 0.83 kg
From the attached scale image,
θ = 40°
Thus;
Measurement = (mcos²θ + M) = ((0.17 cos²40) + 0.83) = 0.93 kg or 930g
