Which materials allow electrons to flow through them?
A. Insulators only
B. Semiconductors and conductors
C. Conductors only
D. Semiconductors and insulators
The materials which allow electrons to flow through them are Semiconductors and conductors. Hence Option (B) is correct.
What are conductors ?A conductor, or electrical conductor, is a substance or material that allows electricity to flow through it.
In a conductor, electrical charge carriers, usually electrons or ions, move easily from atom to atom when voltage is applied.
Therefore, The materials which allow electrons to flow through them are Semiconductors and conductors. Hence Option (B) is correct.

Answer choice 'C'
Explanation:
As the ball slows after kicking generates maximum Kinetic Energy, the ball slows due to its Kinetic Energy being transferred to surroundings because of atmospheric and surface friction until it stops in a state of static equilibrium.
Increased concentrations of greenhouse gases will lead to HIGHER global temperatures.
True
or
False
Answer:
[tex]\huge\boxed{\sf True}[/tex]
Explanation:
If the concentrations of greenhouse gases keep increasing, They will absorb more and more long wave energy coming from the sun and radiating from the earth's surface and thus will cause an increase in temperature.

Find a part of the article that describes signals that are sent within Diego’s body. Where does the signal come from, and how does it cause Diego to feel or react?
Answer:
The sensory receptors send signals to Diego's brain cells. These signals are messages that help Diego figure out what to do next. As Diego thinks, more signals move from one brain cell to another.

What are sensory receptor?The capacity to react to stimuli is one of the traits of a living thing. The highly developed sensory system of humans can concurrently analyze thousands of incoming messages.
Dendrites of sensory neurons are specialized for receiving particular types of stimuli and are known as sensory receptors. There are three ways to classify sensory receptors.
Exteroceptors are located at or close to the skin's surface and are responsive to stimuli coming from the outside or the body's surface. These receptors include those for vision, hearing, smell, and taste as well as those for touch, pain, and temperature.
Therefore, The sensory receptors send signals to Diego's brain cells. These signals are messages that help Diego figure out what to do next. As Diego thinks, more signals move from one brain cell to another.

Copper has a specific heat of 0,900 J(g C). How much energy in kJ is needed to raise the temperature of a 700 g block of aluminum from 30.7°C to 82,1C?(show your steps)
Answer:
32.4 kJ
Explanation:
Given that:
Specific heat capacity fo copper, c = 0.9
Mass of copper, m = 700 g
Temperature change, dθ ;t2 - t1 = (82.1 - 30.7) = 51.4
Energy required, E = mcdθ
E = 700 * 0.9 * 51.4
E = 32382 J
Energy required on kJ
32382 / 1000
= 32.382 kJ
= 32.4 kJ

HELPPP HURRY FIRST GET BRAINLEST The rusting of steel wool occurs when the iron in the steel wool combines with what substance?
carbon dioxide
hydrogen
nitrogen
oxygen
Answer:
iron oxide. aka. oxygen
Explanation:
Rust is the result of a chemical reaction between iron and oxygen, otherwise known as iron oxide. Since steel wool -- and steel in general -- is largely made of iron, steel wool is prone to rust if it doesn't have a rustproof coating on it. The actual reaction that creates rust happens when two iron atoms mix with three oxygen atoms in water; the oxygen bonds to the metal, and a new compound is formed.
The type of potential energy related to an object's height
Answer:
the answer is gravitational potential energy
Answer:
Since the gravitational potential energy of an object is directly proportional to its height above the zero position, a doubling of the height will result in a doubling of the gravitational potential energy. A tripling of the height will result in a tripling of the gravitational potential energy.
