Someone help me with this ASAP!

Answer:

so he can know where to put the heating things so he will know which place will trap the most heat. He will also need to know that depending on where he puts the cooling system, where it will make the most use.

Explanation:

For the first question it is the fourth option. Cryosphere is a term for the portions of earth that are covered in water when the water is in solid form. this includes both snow and ice.

For the second question the answer is a delta is formed at the mouth of the river a sediment is carried down stream. The hydrosphere refers to all water on earth.

Explanation:

Chitin nanowhiskers are primarily used to reinforce polymer nanocomposites, but they are also used to prepare scaffolds, hydrogels, and sterile gauze, as sorbent materials in industry, water purification, and so on.

Nanowhiskers are a type of crystal nanofiber with a diameter less than 100nm and a length-to-diameter ratio greater than 100.

Fullerene nanowhiskers (FNWs) are thin crystalline fibers made up of C60, C70, endohedral, or functionalized fullerene molecules.

The Nanowhiskers repel stains by creating an air cushion around each cotton fiber. When something is spilled on the fabric's surface, the miniature whiskers actually prop up the liquid drops, allowing them to roll off.

Chitin nanowhiskers are principally sometimes used reaffirm nanocomposite, but they are also employed to make scaffolds, hydrogels, and sterile gauze, as well as sorbent materials in industry and water purification.

Thus, these are some of the uses of nano-whiskers.

Answer:

D

Explanation:

Energy is never created nor destroyed.

If an object falls through the air, gaining speed as it falls. A student claims that this creates new energy, and so it breaks the law of energy, then the statement describing why the student is incorrect is "Energy is converted from other forms not created, therefore the correct answer is option D.

Mechanical energy is the combination of all the energy in motion represented by total kinetic energy and the total stored energy in the system which is represented by total potential energy.

As given in the problem statement If an object falls through the air, gaining speed as it falls. A student claims that this creates new energy, and so it breaks the law of energy.

"The energy is neither created nor destroyed it can only convert from one form to another".

Thus, the correct answer is option D.

1._Light behaves as a wave - it undergoes reflection, refraction, and diffraction just like any wave would. Yet there is still more reason to believe in the wavelike nature of light

2._Light behaves as a particle When UV light hits a metal surface, it causes an emission of electrons. Albert Einstein explained this "photoelectric" effect by proposing that light

Explanation:

The mass of Liquid 1 + mass of Liquid 2 = mass of solid + mass of gas supports the law of conservation of mass option (D) is correct.

A tangible body's mass is the amount of matter it possesses. It's also a metric of inertia or the resistance to velocity when a net force is exerted.

As we know,

The law of conservation of mass is also known as the principle of mass conservation.

In physics and chemistry state that for any system close to all transfers of matter and energy.

The mass of the system must remain constant over time because the mass of the system cannot change and therefore quantity cannot be added to or subtracted.

Thus, the mass of Liquid 1 + mass of Liquid 2 = mass of solid + mass of gas supports the law of conservation of mass option (D) is correct.

Explanation:

Friction helps to move

and friction hurt if you if the floor is washed by washing powder and floor is wet and you can fell....

Answer:

Explanation:

Advantages/uses/helpful ;

•Being able to walk across a surface without slipping. This is static friction.

•Writing on a piece of paper with a pencil or a pen. This is sliding friction.

•Driving a car across the road surface. This is rolling friction.

Disadvantage/hurts you;

•Static friction must be overcome, by either muscle tension or gravity , in order to move. Once moving, kinetic friction acts to oppose motion, cause wear on joint surfaces, generate thermal energy , and make the body less efficient.

•Friction produces unnecessary heat leading to the wastage of energy.

Answer:

vf = 27.4 [m/s]

Explanation:

Para poder simplificar tiene que identificar las unidades que tiene en la ecuacion:

0.08 [m/s²] = aceleracion

180 [s] = tiempo

13 [m/s] = velocidad

al multiplicar aceleracion por tiempo podemos obtener velocidad ya que el tiempo se elimina con segundos al cuadrado

[tex][\frac{m}{s^{2} } ]*[s] = [\frac{m}{s} ][/tex]

vf = 13 + (0.08*180)

vf = 13 + 14.4

vf = 27.4 [m/s]
