Final answer:
According to Freud, "the id is the largest part of a person's personality" because it encompasses instinctual drives and operates entirely in the unconscious.
Explanation:
According to Freud, the largest part of a person's personality is the unconscious, which includes the id, ego, and superego. While the ego operates in the conscious and serves as the mediator between the id and the superego, it is the id that forms the largest component, as it encompasses basic instinctual drives and is entirely unconscious. Freud's theory posits that the unconscious mind holds repressed memories and desires that significantly influence conscious behavior and personality development, with the id being a primary force driving pleasure-seeking behavior.

a plane travels 2.5 km at an angle of 35 degrees to the ground and then changes Direction and travels 5.2 km and an angle of 22 degrees to the ground what is the magnitude and direction of the Plains total displacement
We can solve for the resultant x and y components by using the sine and cosine functions.
resultant x = 2.5 cos 35 + 5.2 cos 22 = 6.87 km
resultant y = 2.5 sin 35 + 5.2 sin 22 = 3.38 km
The resultant displacement is calculated using hypotenuse equation:
displacement = sqrt (6.87^2 + 3.38^2)
displacement = 7.66 km
The resultant angle is:
θ = tan^-1 (3.38 / 6.87)
θ = 26.20°
Therefore the magnitude and direction is:
7.66 km, 26.20° to the ground
What is acceleration?
a) the change of velocity over distance
b) the change of inertia over time
c) the change of velocity over time
d) the change of speed over time
C) The change of velocity over time
Final answer:
Acceleration is the rate of change of velocity over time. It is a vector quantity that can signify speeding up or slowing down and is measured in meters per second squared. So the correct option is c.
Explanation:
Acceleration is the rate at which velocity changes over time and can involve a change in speed, direction, or both. The formula for average acceleration is given by the change in velocity (∆v) divided by the time interval (∆t) over which this change occurs. It is important to note that acceleration is a vector quantity, meaning it has both magnitude and direction. Thus, acceleration can be positive (speeding up) or negative (slowing down, also known as deceleration). The SI unit for acceleration is meters per second squared (m/s2).
Therefore, the correct answer to the question 'What is acceleration?' is c) the change of velocity over time.

why did dalton devise his own element symbols
Final answer:
John Dalton created his own element symbols to visually represent the atoms and their combinations as part of his atomic theory. These symbols were crucial for the systematization of chemistry and preceded other symbol systems such as those of G. N. Lewis, which illustrate valence electrons and chemical bonding.
Explanation:
John Dalton, an English scientist, devised his own element symbols as part of his pioneering work in atomic theory. Dalton's atomic theory posited that elements are composed of indivisible atoms, that matter combines in fixed ratios, and that compounds always have consistent proportions. His element symbols, depicted in Dalton's book A New System of Chemical Philosophy, were an early attempt to represent these atoms and their combinations visually. These symbols laid the groundwork for the systematization of chemistry and were a precursor to later representations such as the Lewis dot symbols. Unlike Dalton's symbols, Lewis dot symbols focus on representing the valence electrons of atoms to predict chemical bonding and formation, as G. N. Lewis published in 1916.
Without Dalton's work, our understanding of the chemical composition of matter and the development of subsequent theories of chemical bonding, such as those proposed by G. N. Lewis, might have been significantly delayed. Dalton's dedication to empirical evidence and experimentation set his atomic theory apart from the philosophical ideas of ancient Greeks like Democritus and Leucippus, contributing greatly to the advancement of modern science and chemistry.

answer these questions "type of heat transfer that occurs between the sun and venus" "measure of the average value of the kinetic energy of the molecules in a substance" "materials like aluminium pans and metal spoons that easily transfer heat" "measure of how well a substance absorbs heat" "type of energy that depends on how fast the molecules in a substance are moving" " temperature scale in which a reading of 0 equals the freezing point of water" "what does a doctor use to measure the average kinetic energy of the molecules in your body"
please please answer all of them and go in order
Heat transfer from the Sun to Venus occurs via radiation, and the measure of molecular kinetic energy in a substance is temperature. Conductors like aluminium transfer heat efficiently, specific heat denotes a substance's heat absorption capacity, thermal energy depends on molecular motion, and a thermometer is used by doctors to measure body temperature.
The type of heat transfer that occurs between the Sun and Venus is known as radiation. This is the transfer of energy by electromagnetic waves, which does not require a medium to travel through space.
The measure of the average value of the kinetic energy of the molecules in a substance is called temperature. Higher temperatures correspond to higher average kinetic energy among the molecules of a substance.
Materials like aluminium pans and metal spoons that easily transfer heat are called conductors. These materials are efficient in transferring thermal energy through direct contact.
The measure of how well a substance absorbs heat is known as its specific heat. It is the amount of heat per unit mass required to raise the temperature by one degree Celsius.
The type of energy that depends on how fast the molecules in a substance are moving is called thermal energy. Higher speeds of molecular motion correlate with higher thermal energy.
The temperature scale is which a reading of 0 equals the freezing point of water is the Celsius scale, also known as Centigrade.
To measure the average kinetic energy of the molecules in your body, a doctor would use a thermometer. The reading is a direct indication of your body's temperature.

On a hot summer day several swimmers decide to jump into a river. They step off the bridge and strike the water at 1.5s later. Ignore air resistance. What is the height of the bridge?
I did it but I don’t know if it’s right
When on a hot summer day several swimmers decide to jump into a river. They step off the bridge and strike the water 1.5 seconds later. Ignore air resistance, then the height of the bridge would be 11.03 meters.
What are the three equations of motion?There are three equations of motion given by Newton,
v = u + at
S = ut + 1/2×a×t²
v² - u² = 2×a×s
As given in the problem, when on a hot summer day several swimmers decide to jump into a river. They step off the bridge and strike the water 1.5 seconds later. Ignore air resistance,
By using the Second equation of motion,
S = ut + 1/2×a×t²
S = 0 + 0.5*9.81*1.5²
S = 11.03 meters
Thus, the height of the bridge would be 11.03 meters.

Is it possible for you to take a hike and have the distance you cover be equal to the magnitude of your displacement?
Distance can be equal to displacement ... if the motion is all in a straight line ... but distance can never be greater than displacement.
Yes, it is possible that the distance can be equal to the displacement. a further explanation is given below.
A intervals metric that is taken somewhere across a track could be determined as the Distance, and the measurement of just a specific duration or short timeframe could be considered as a Displacement.Whenever you walk down the road throughout the one manner, the distance, as well as the size of the whole movement, become equivalent or comparable.
