Answers
Answer:27
Explanation:
Use this sentence: On a summer day, the heat of the land heats the air, causing it to rise and spread before cooling over the ocean, creating a
breeze.
How is thermal energy transferred when this happens?
(1 point)
through radiation
Othrough refraction
through convection
O through conduction
Answers
Thermal energy may be transferred from one place to another in solids, liquids, or gases by conduction, convection, or radiation. Convection allows heat to be transferred from water to air and then distributed throughout the ocean. (Option C)
What is Convection?Convection currents are formed by radioactive decay in the core when heat rises and falls inside the mantle. The plates are moved by convection currents. Plates migrate apart where convection currents separate near the Earth's crust. Plates migrate towards each other when convection currents converge.
Temperature gradients form a specific fluid, the difference in densities of which causes convection currents. This suggests that convection currents play an important part in fluid circulation.
These currents aid in the transport of heat from one location to another by utilizing the mass motion of a specific fluid such as water, air, or even molten rock.
This heat transfer function of convection currents contributes to the Earth's ocean currents, atmospheric weather, and general geology. Convection currents in the Earth's mantle are considered to be the driving force behind the tectonic plates.

Answers
The mass, in grams, of the second piece of wood is; 180 grams
How to find the density of an object?We are given;
Mass of first wood = 30 grams
Volume of first wood = 40 cubic centimeters(cm³).
The formula for the density of an object is;
Density = mass/volume
Thus
Density = 30/40
Density = 0.75 g/cm³
Now, the second piece of wood has the same density (g/cm³) and a volume of 240 cm³.
Thus;
Mass of second wood/240 = 0.75
Mass of second wood = 240 * 0.75
Mass of second wood = 180 g

Explain the comparative uses of the USDA Hardiness Zones and the Koppen-Geiger Scale.
Answers
The USDA Hardiness Zones are a system developed by the United States Department of Agriculture (USDA) to define climate zones based on the average annual minimum temperature. This system is primarily used to help gardeners and farmers determine which plants will grow best in a particular area. The zones range from 1 (coldest) to 13 (warmest), with each zone having a 10-degree Fahrenheit range of average annual minimum temperature.
On the other hand, the Koppen-Geiger Scale is a more comprehensive system that classifies climates based on several factors, including temperature, precipitation, and vegetation. This system is used by climatologists and geographers to study climate patterns on a global scale. The Koppen-Geiger Scale divides climates into five major groups: tropical, dry, temperate, continental, and polar. Each group is further divided into subcategories based on additional climate factors.
Overall, while both the USDA Hardiness Zones and the Koppen-Geiger Scale are used to categorize climates, they serve different purposes and have different levels of complexity. The USDA Hardiness Zones are mainly used for agricultural purposes and focus on temperature, while the Koppen-Geiger Scale is a more comprehensive system used by scientists to study climate patterns on a global scale.

During an activity analysis, a human resources manager determined that an employee spent 1.7
hours making work calls one week, which was 4% of the employee's total work hours for the
week. How many hours did the employee work?
Answers
Answer: 42.5 hours
Explanation:
Let the number of hours that the employee work be represented by x.
Since the employee spent 1.7 hours making work calls one week, which was 4% of the employee's total work hours for the week, this can be represented in an equation as:
4% × x = 1.7
4/100 × x = 1.7
0.04 × x = 1.7
0.04x = 1.7
x = 1.7 / 0.04
x = 42.5 hours
The employee worked for 42.5 hours

What is Animation?
Animation is a method of creating the illusion of movement in a sequence by photographing successive drawings, models, or even puppets. Because our eyes can only hold an image for about a tenth of a second, when multiple images appear in quick succession, the brain merges them into a single moving image.
Traditional animation involves drawing or painting images on transparent celluloid sheets to be photographed. Early cartoons are examples of this, but most animated films today are created using computer-generated imagery, or CGI.
Frame rate, or the number of consecutive images displayed each second, is considered to create the appearance of smooth motion from these drawn, painted, or computer-generated images.
Moving characters are typically shot "on twos," which simply means that one image is displayed for two frames, for a total of 12 drawings per second. Motion is possible at 12 frames per second, but it may appear choppy. A frame rate of 24 frames per second is frequently used in film to achieve smooth motion.
