explain how a metal chair can get too hot to sit on when it has been left out in direct sunlight
Answers
A piece of metal can feel much hotter than the surrounding air because metals and most solids are better conductors of heat than air. So, while the metal of the chair is absorbing photons from the sun, the air isn’t carrying much of that heat away.
Thermal conductivity is substantially higher for metals. Accordingly, at a given temperature differential, metals can transfer more heat than non-metal objects in a given unit of time.
Metals effectively conduct heat. Heat spreads quickly via materials that are good conductors. As a result, a metal chair that has been exposed to bright sunlight may become uncomfortably warm to sit on.
What are the characteristics of metals?In chemistry, an element is considered to be metal if it readily forms the positive ions known as cations and has a propensity to create metallic bonds. The chemical and physical characteristics of the metals, such as malleability, ductility, ionization, bonding qualities, etc., serve to identify them from one another.
Metals are good conductors of heat and electricity, as well as being malleable. Other features include: Metals are solids at ambient temperature, with the exception of mercury, which is a liquid at that temperature (Gallium is liquid on hot days).

Answers
Institutions can be effective by promoting transparency and protecting sports personalities' rights, but may be ineffective if poorly regulated.
Institutions can be effective in safeguarding sports personalities' rights by implementing transparent policies, promoting ethical practices, and ensuring compliance with relevant laws. This can protect athletes from undue media scrutiny and violation of their privacy.
However, some institutions may be ineffective due to inadequate regulations, inconsistent enforcement, or lack of resources, which can result in athletes' rights being compromised.
As for my position, I believe it is essential to strike a balance between the media's right to report and sports personalities' rights to privacy, with institutions playing a crucial role in maintaining that balance.

The correct answer is a Fold mountain.
Fold mountains are the mountains which are formed when two or more Earth's tectonic plates are pushed together. At the boundaries where this compression and collision has held, the rocks and debris get warped and folded into hills and mountains.
Fold mountains are mostly made up of sedimentary rocks and metamorphic rocks. These rocks are formed under high pressure and relatively low temperatures. Examples of Fold mountains include The Himalayas, the Rockies, The Alps, the Aravalli, etc.
Fold mountains are related to the continental crust as they are created at compression zones where the continental plate boundaries converge.

Answers
b) the game being hunted is a factor in determining a zone-of-fire.
A zone-of-fire is the region in which a hunter can shoot without risk. Hunters should decide on the zone-of-fire each member will cover prior to departing as a group.
A zone-of-fire is determined by a variety of elements, including the hunter's shooting skills, the prey being pursued, the hunting terrain, and the hunting tactics employed.
The zone of fire for a hunter shifts with each movement. Groups that go out to hunt small game, such as birds or rabbits, are especially susceptible to this.
Outside of the safe zone-of-fire, a hunter is not permitted to swing or fire. It's preferable to keep groups of hunters to three people or less for reasons of safety. Two is a safer number for novice hunters until they gain experience with maintaining a proper zone-of-fire.

“The use by states and localities of criminal laws to go after undocumented immigrants simply for being undocumented is generally unlawful, because the federal government has sole power to regulate immigration. For example, in 2005, two New Hampshire sheriffs arrested and prosecuted several undocumented immigrants for “criminal trespass,” accusing them of being in New Hampshire unlawfully solely because they were undocumented. The state court that heard the case concluded(PDF) that the state law could not be used in that way because only the federal government can regulate immigration”.

Answers
Sociology and psychology are the two different branches related with the study of science that deal with different aspects like human behavior and human interventions. This statement is True.
Sociology is the study of life, change and the social determinants and effects of human tendencies. Sociologists study how individuals interact in organizations and societies, as well as their group structures. All human behavior is social, hence sociology's subject matter spans from the close-knit family to the violent mob, from organized crime to religious cults, from racial, gender and social class distinctions to the shared values of a common culture.
Psychology is the study of the human mind and its functions. It includes everything that determines how people think, react and feel, including biological influences, societal forces and environmental circumstances. People can gain insights into their own behavior as well as a better knowledge of other people by developing a deeper understanding of the subject.
