B. They were told that they had very severe cases of stuttering.
The Monster Study was conducted by Dr. Wendell Johnson to learn more about why children developed a stutter and to see if stuttering was a result of learned behavior. However, there are several ethical problems with the the Monster study.
In this study, psychologists tell the group of orphans who did not suffer from stuttering that they had very severe cases of stuttering.

Answer:
They were told that they had very severe cases of stuttering.
Explanation:
The monster study conducted in 1939 was a certain stuttering experiment that was done by Wendell Johnson on 22 Orphan at the University of Iowa, United States. Eleven of the children got positive speech therapy while the other half was seen to have negative speech therapy which belittled them for their speech imperfections.
The experiment was called monster because many people were horrified that such experiments could be done on children who were orphans.
Answer;
-kinetic energy transformed to mechanical energy
Explanation;
-When the blades are moved or spins (rotational motion) some part of the kinetic energy of the wind is transformed into rotational kinetic energy of the the blades, which makes an axis rotate generating the electricity.
-KInetic energy is mechanical energy (mechanical energy is basically kinetic energy and gravitational potential energy).
-Therefore, the kinetic energy of the wind is transformed into kinetic energy of the windmill (mechanical energy) and it is then transformed into electrical energy.
Wind power is produced from the wind turbines or sails that uses air flow to convert it into mechanical power. It is an alternative to fossil fuel burning, it is all around, renewable, clean, produces no greenhouse gases and uses little land. The advantages of wind power have been greatly praised by many. However, it has disadvantages. Wind power especially at farm is noisy and may spoil the view for their neighboring people. Also the amount of electricity depends on the strength of the wind. If no wind is around, no electricity is produced.
B. 13.7 millimeters
C. 51 millimeters
D. 189 millimeters
Answer:
Electro-negativity is the tendency of an atom to attract the shared pair of electron in a covalent bonding while forming a molecule.
Explanation:
In a covalent bonding the atoms share the electrons mutually without actually transferring it to one of the atom to gain a stable configuration. In such a case when one atom is more electro-negative than the other then the shared pair of electron gets slightly shifted towards the more electro-negative developing a denser cloud of electrons near the nucleus of that atom which we denote as partial negative () in the superscript.
In water molecules we have a similar case where the oxygen atom is more eletro-negative (value=3.44) than the hydrogen atom (value=2.2). This leads to a higher electron density near the oxygen atom. A part from the shared pairs, the oxygen atom also possesses 2 lone pairs of electrons which tend tp makethe shape a tetrahedron in a 3D structure. This results in molecular shape being bent with an H-O-H angle of 104.5°.
B. compound
C. composite
D. mixture
Answer:
A. element
Explanation:
A molecule is formed when two or more atoms join together chemically. If atoms combine that are of two or more different elements, we call that a compound. All compounds are molecules, but not all molecules are compounds.

The frequency at which the stationary listener will hear the sound of the plane as it approaches is 5.54 KHz
Applying the equation of Doppler effect, the observer's frequency can be obtained as follow:
f₀ = [(v + v₀) / (v – vₛ)]f
f₀ = [(334 + 0) / (334 – 114)] × 3.65
f₀ = [334 / 220] × 3.65
f₀ = 5.54 KHz
Learn more about Doppler effect:
Answer:
Explanation:
velocity of source, Vs = 114 m/s
original frequency, f = 3.65 kHz
velocity of observer , Vo = 0 m/s
velocity of sound, v = 334 m/s
let the frequency is f'.
The formula for the doppler effect is given by
where, v is the velocity of sound.
f' = 5.54 kHz
