Since the horizontal velocity is what is doubled, that does not affect the fall of the ball, thus the fall is still 5 seconds long.
Question: How will heat flow between objects?
from the colder object to the warmer object
from the bottom object to the object on top
from the warmer object to the colder object
back and forth between objects of equal temperature
Answer: Without an external agent doing work, heat will always flow from a hotter to a cooler object. Two objects of different temperature always interact. There are three different ways for heat to flow from one object to another. They are conduction, convection, and radiation.
Conduction: The process by which heat or electricity is directly transmitted through a substance when there is a difference of temperature or of electrical potential between adjoining regions, without movement of the material.
Convection: The movement caused within a fluid by the tendency of hotter and therefore less dense material to rise, and colder, denser material to sink under the influence of gravity, which consequently results in transfer of heat.
Radiation: The emission of energy as electromagnetic waves or as moving subatomic particles, especially high-energy particles that cause ionization.
Hope this helps, have a good day. c;
The inner planets are;- Mercury, Venus, Earth and Mars. Earth is the only planet which has atmosphere, water on the surface or know of to have water(Mars might have water underground), and life.
Mercury is pretty much a small planet on fire by day, but freezes at night.
Venus is a gas planet which is usually on fire in places too, but has mass ice craters on the surface.
Earth, well just look out your window.
Mars may have been an earth like planet at one stage, (still unknown) but is known as the red planet due to its volcanic activity. Mars also has the biggest mountain/volcano on any known planet called Mt Olympus. It's 3 times the size of Mt Everest.
Hope this helps!! :)
The correct answer to the question is A) Electrons.
EXPLANATION:
The electrical conductivity of a metal or any substance depends on the free electron concentration of the metals.
Free electrons are those electrons which are present in the conduction band of the metals. These electrons experience less amount of force attraction from the nucleus. Protons and neutrons do not contribute anything to the current conduction in a metal.These sub atomic particles are bound to the nuclei of atoms.
When we maintain potential difference across the two ends of a conductor, the free electrons are drifted towards the positive terminal of the battery.
Hence, electrical conductivity of a substance is the ability of the electrons to move inside the substance.
More is the conductivity of the substance, the lesser is the resistance to the flow of electrons inside the substance, and vice versa.
