((Psychology))According to Sternberg, consummate love includes:
A. attraction and low commitment.
B. intimacy, commitment, and passion.
C. passion, romance, and little responsibility.
D. passion and high commitment.
Answer:
The correct answer is B. According to Sternberg, consummate love includes intimacy, commitment, and passion.
Explanation:
The triangular love theory of the American psychologist Robert Sternberg characterizes love in an interpersonal relationship according to three different components, which are intimacy, passion and commitment:
-Intimacy, understood as those feelings within a relationship that promote the approach, the link, the connection and mainly the self-revelation. Or in other words, the affection towards another person that arises from feelings of closeness, affective bond and relationship, implies the desire to give, to receive, to share, and so on.
-Passion, as a state of intense desire for union with the other, as an expression of desires and needs, great sexual or romantic desire accompanied by psychological excitement.
-Commitment, the decision to love another person and the commitment to maintain that love. This component implies maintaining the relationship in good times and bad times

chemistry
forensic science
legal
medical
Final answer:
In the early 1800s, forensic scientists, such as chemists and medical doctors, began to provide evidence in court related to physical evidence from crime scenes. Option b
Explanation:
During the early 1800s, forensic science was a field where professionals, including medical doctors and sometimes chemists, provided scientific evidence in courts to assist legal proceedings.
These individuals would analyze physical evidence from crime scenes, such as hair, blood, and other body fluids, and increasingly, DNA. They played crucial roles in determining the facts of criminal cases by examining forensic evidence left at crime scenes.
This period marked the beginning of the systematic application of science to legal processes, a practice that would grow significantly with advancements in technology and methodology. Option b
ASAP Which of the following has kinetic energy? a. a rock poised for a fall b. an archer’s bow that is drawn back c. a rolling bowling ball d. a car waiting at a red light
The correct answer is c. a rolling bowling ball.
Explanation:The correct answer is c. a rolling bowling ball.
Kinetic energy is the energy an object possesses due to its motion. It depends on the mass and velocity of the object. In this case, a rolling bowling ball has kinetic energy because it is moving. The other options do not involve motion and therefore do not have kinetic energy.
For example, a rock poised for a fall has only potential energy, as it does not possess motion. An archer's bow that is drawn back also has potential energy stored in the stretched bowstring, but it does not have kinetic energy until the arrow is released. A car waiting at a red light is stationary and not in motion, so it does not have kinetic energy.

Explanation:
what do waves transmit?
Answer:
Waves only transport a portion of energy.
Explanation:
Let's think about some examples related to waves in nature:
An electromagnetic wave is a combination of electric and magnetic fields, both of them oscillate through space and time. That oscillation transport energy, that is bounded in little "packets" of energy called photons. So this wave transmits energy.In the case of a solid, the periodic oscillation of the molecules, this kind of oscillation transport energy too and in this particular case it is called phonons. It is just a quantum of energy related to a compression wave, as a sound or a vibration lattice in a crystal.In conclusion, waves only transport a portion of energy.

Why is it inadvisable to make a horseshoe magnet from a flexible material? 1. a flexible material is not easily magnetized. 2. a flexible material is easily loses its magnetism. 3. none of these 4. the poles of the magnet attract each other and will cause the magnet to bend. 5. a flexible material cannot be easily made into a horseshoe shape?
Different magnetic poles are drawn to one another. The magnet will bend if it is too flexible, possibly allowing the poles to touch and reducing the magnetic field around it.
What horseshoe magnet from a flexible material?Since a horseshoe magnet's design naturally provides more strength than a bar magnet does, it quickly superseded the bar magnet in use. The magnet's poles are situated closer to one another and in the same plane thanks to the U-shape.
The majority of horseshoes are constructed of steel, though there are a few outliers. Because aluminum horseshoes are lighter and perform better when speed is the primary goal, racehorses typically wear them.
At the magnet's poles are concentrated its strongest elements. Because of this, a horseshoe shape is thought to be the strongest.
Therefore, particularly handy to produce if you need to carry heavy goods or strengthen a bar magnet.

What type of radiation can penetrate deepest into exposed materials?
An airplane flies 930 miles in 75 minutes. how many miles does it fly in 5 hours and 45 minutes assuming a constant speed?
First, calculate the average speed of the airplane, which is 12.4 miles per minute. Then, convert 5 hours and 45 minutes into minutes which is 345 minutes. Multiple the speed by this time to find the distance the airplane would fly, which is 4278 miles.
Explanation:To solve this problem, we first need to figure out the average speed of the airplane. Average speed is calculated by dividing the total distance by total time. In this case, the airplane travels 930 miles in 75 minutes. So the speed is 930 miles/75 minutes = 12.4 miles/minute.
Now that we have the speed per minute, we can calculate how many miles the airplane would travel in 5 hours and 45 minutes. This time converts to 345 minutes (since 1 hour = 60 minutes). So, the airplane would fly 12.4 miles/minute * 345 minutes = 4278 miles.

Final answer:
Answer to Question 8 is B) Integrated circuit. Answer to Question 9 is C) 180 watts, calculated using the power formula P = IV where I is current and V is voltage determined by Ohm's law.
Explanation:
Solution for Question 8:
A thin slice of silicon that contains many solid-state components and is referred to in the question is known as a(n) Integrated Circuit (IC). This is because an integrated circuit consists of numerous semiconductor devices like transistors, diodes, and resistors that are fabricated onto a single piece of semiconductor material, typically silicon. Therefore, the correct answer is B) Integrated circuit.
Solution for Question 9:
To calculate the power consumed by a motor when a current of 6.0 amps passes through it and it has a resistance of 5.0 ohms, we use the formula for electrical power, P = IV (Power = Current × Voltage). Since we know the current (I) and the resistance (R), we first need to find the voltage (V) using Ohm's law, V = IR (Voltage = Current × Resistance). Plugging in the values, we get V = 6.0 A × 5.0 Ω = 30.0 V. Now we can calculate the power, P = 6.0 A × 30.0 V = 180 watts. Thus, the correct answer is C) 180 watts.

Which of the following are disadvantages of solar energy?
The disadvantages of solar energy primarily include its dependency on weather, need for large space, requirement of rare-earth minerals for photovoltaic cells, and potentially high costs.
Explanation:The main disadvantages of solar energy are largely tied to its dependence on weather conditions and the requirement of considerable space. Solar energy generation is chiefly affected by cloud cover, nightfall, and incident angle strike at high altitudes that influence the amount of light energy available. While solar energy conversion does not necessarily require connection to large-scale power grids, making it beneficial for remote locations, it does rely on the creation of photovoltaic cells which require rare-earth minerals that can be difficult to obtain. Additionally, the price of solar energy, despite falling dramatically, may still present as a financial barrier for some.

Explanation;Mosses are located in the ground zone of the deciduous forests.Deciduous forests is a biome that has a soil that is rich and the leaves are dropped from the trees to provide a source of organic matter for the soil.Mosses plants are types of plants which belongs to the bryophyta group of plants. They lack roots and are evergreen plants that grow in a wide range of environments but are commonly found covering the ground, along the stream beds, and also at the bases of the trees in deciduous forests.How much heat is required to warm 1.40 l of water from 20.0 ∘c to 100.0 ∘c? (assume a density of 1.0g/ml for the water.)?
The amount of heat required to warm the water can be calculated using the formula Q = mcΔT, where Q is the heat energy, m is the mass of water, c is the specific heat capacity of water, and ΔT is the change in temperature. Therefore, the amount of heat required to warm 1.40 L of water from 20.0 °C to 100.0 °C is 468,352 J.
Explanation:The amount of heat required to warm the water can be calculated using the formula:
Q = mcΔT
Where Q is the heat energy, m is the mass of water, c is the specific heat capacity of water, and ΔT is the change in temperature.
Given that the density of water is 1.0 g/mL and the volume of water is 1.40 L, the mass of water can be calculated as:
m = density × volume = 1.0 g/mL × 1.40 L × 1000 mL/L = 1400 g
The change in temperature is 100.0 °C - 20.0 °C = 80.0 °C.
Substituting the values into the formula:
Q = (1400 g)(4.184 J/g °C)(80.0 °C) = 468,352 J.
Therefore, the amount of heat required to warm 1.40 L of water from 20.0 °C to 100.0 °C is 468,352 J.
