Answer: B
Explanation: Gravitational force depends on the mass of the objects and the distance between them. The greater the mass, the greater the force. The shorter the distance, the greater the force. To find which would have the most force, you want to find the option where the objects have the most mass and the shortest distance, and the second choice fits the criteria.

Explanation:
a. In subtropical areas like the Caribbean Sea and the Gulf of Mexico, maritime tropical air develops.
Explain about the characteristics air mass?Large air masses are capable of engulfing substantial portions of a continent's or a body of water's land surface. They penetrate the troposphere far up.The mass as a whole experiences similar temperatures and humidity levels. Nonetheless, as an air mass shifts away it from point of origin, its temperature and humidity do change.A: In subtropical areas like the Caribbean Sea and the Gulf of Mexico, maritime tropical air develops. It is connected to thunderstorms and warm, muggy weather.
B: Continental Large, high-latitude land masses, like northern Canada or Siberia, are where polar air masses form. It comes from northern Canada or Alaska in the Northern Hemisphere. It transports dry weather to the United States as it goes south. Low humidity and temperature are both present.

“How can I describe and
compare objects and materials based on odor and taste?
Answer:
There are several ways to describe and compare materials based on odor and taste. This includes adjectives that describe the object/materials,
Explanation:
You can definitely describe and compare objects and materials based on odor and taste with the help of adjectives.
How many types of objects are there based on taste?There are five types of objects or materials that are based on the attribute of taste. This is because of taste receptors in the mouth sense the five taste modalities. It incudes sweetness, sourness, saltiness, bitterness, and savoriness (also known as savory or umami).
Scientists have classified odors into 10 basic categories: fragrant, woody/resinous, minty/peppermint, sweet, chemical, popcorn, lemon, fruity (non-citrus), pungent and decayed.
Both taste and odor of the materials and objects are represented with the help of a part of speech known as adjectives. Adjectives can be used to describe the qualities of someone or something independently or in comparison to something else, such as taste, color, odor, etc.
Therefore, you can definitely describe and compare objects and materials based on odor and taste with the help of adjectives.

I need help to know if I put enough information into my concept map or I need to add more?
Here are the instructions:
Your concept map will compare the manner in which energy is transferred by mechanical waves and electromagnetic waves. Include the following somewhere in your concept map:
types of energy transferred
medium required (if applicable) for transfer of energy
speed of energy transfer through various mediums (solid, liquid, gas)
Explanation:
One of the various ways that energy moves through space is by electromagnetic radiation.
Electromagnetic radiation includes the heat from a blazing fire, the sun's light, the X-rays used by your doctor, and the energy used to cook food in a microwave.
Waves are recognizable to anyone who has ever gone swimming in the ocean.
Electromagnetic waves are similar, however they differ in that they are made up of 222 waves that oscillate perpendicular to one another.
An oscillating magnetic field is one of the waves, while an oscillating electric field is the other.
Mechanical waves travel in a vacuum, whereas electromagnetic waves travel in a vacuum. Mechanical waves require the assistance of a medium to travel and can only travel at the speed of that medium whereas electromagnetic waves can pass through any medium.

How do you find the mechanical advantage of a gear?
Answer:
we can find by using formula load upon effort
Answer:
Calculate the mechanical advantage of a gear train. The mechanical advantage of a gear couple is given by MA = T_o/T_i where T_x is the number of gear teeth on gear x, o=output, and i=input. For stacked gear couples the overall mechanical advantage is the product of the individual mechanical advantages

write down everything that you know about heat temperature pressure and heat transfer
Answer:
Heat is always transferred from the object at the higher temperature to the object with the lower temperature. For a gas, the heat transfer is related to a change in temperature. The temperature, pressure, and volume of the gas determine the state of the gas. Heating a gas changes the state of the gas.
Explanation:
This is something I know about heat temperature pressure and heat transfer
The object with the higher temperature always transfers heat to the thing with the lower temperature. The heat transfer for gas is connected to a temperature change.
What is meant by heat transfer?Heat transfer is defined by thermodynamic systems as "The transfer of heat over the system boundary caused by a temperature difference between the system and its surroundings."There are several ways for heat to go from one place to another. The many heat transmission mechanisms consist of:Conduction: Thermal energy is transferred from an area with higher kinetic energy to an area with lower kinetic energy. Slow-moving particles gain kinetic energy as a result of collisions between high-speed and slow-moving particles. This common type of heat transmission occurs when two objects physically touch. Convection: The flow of fluid molecules from higher temperature regions to lower temperature regions is referred to as convection.Radiation: Radiant heat is the name for thermal radiations. Emission of electromagnetic waves results in the production of thermal radiation. The energy from the producing body is removed by these waves. A vacuum or transparent media, which can be made of solid or liquid, is used for radiation transmission.To learn more about heat transfer, refer to:

A . hydrogen : 1 amu
B. Nirtogen 14 amu
C . Oxygen 16 amu
D. Boron 10 amu
Answer:
The element that has the highest combined number of protons and neutrons is Oxygen: 16 amu
Explanation:
The atomic mass unit (amu) of an element is the sum of the number of protons and neutrons in the atom of that element.
The atomic mass unit of the element reveals the total number of protons and neutrons in the element.
Since oxygen (16 a.m.u) has the highest atomic mass unit among the given elements in this question, therefore, it has the highest combined number of protons and neutrons.

Answer:
Radio waves and the are various frequencies of radio waves are used for television and FM and AM radio broadcasts, military communications, mobile phones, ham radio, wireless computer networks, and numerous other communications applications. They are important because Radio waves are very widely used in modern technology for fixed and mobile radio communication, broadcasting, radar and radio navigation systems, communications satellites, wireless computer networks and many other applications.
Microwaves are widely used in modern technology, for example in point-to-point communication links, wireless networks, microwave radio relay networks, radar, satellite and spacecraft communication. They are important because microwaves play an increasingly wide role in heating and cooking food. They are absorbed by water and fat in foodstuffs (e.g., in the tissue of meats) and produce heat from the inside. In most cases, this reduces the cooking time a hundredfold.

Why is it less noisy stomping on carpet than stomping on tile floors?
Answer:
Carpet softens harsh sounds and creates a quieter, more peaceful indoor environment. The installation of carpet and underlay is the only method available for eliminating excessive noise generated by floor impacts such as noise produced from footfalls, chairs scraped across the floor and objects dropped on the floor.
Explanation:
Carpets are thicker. That's why when you stomp it's more quieter because the impact of your foot will hit the thickness.
