I NEED HELP WIT MY SCIENCE GIZMO PAGE 4 QUESTION 3 THIS IS ALREADY LATE SO I NEED HELPPPP!!!!!!
In science, some quantities are known as vectors. Acceleration is one type of vector. Which of the following is an example of an acceleration vector?
Answer: 5 m/s 2 south
Explanation:
Vector quantities have both magnitude and direction.
Scalar quantities have only magnitude.
Distance is a scalar quantity. It refers only to how far an object has traveled. For example, 4 feet is a distance; it gives no information about direction. To say an object traveled 4 feet is somewhat ambiguous. To say the object traveled 4 feet west, for example, would be a displacement, and would then be a vector quantity. It gives a more complete picture of what happened.
Mass is a scalar quantity. Simply put, it refers to how much matter an object is made up of. It has magnitude but gives no indication of direction in any sense. The vector counterpart to mass is weight.
Weight is a vector quantity. Weight is a force, and forces are vectors, i.e. having both magnitude and direction. Perceived weight of an object at rest on earth is given by
W
=
→
F
g
=
m
g
, the product of the mass of the object and the free-fall acceleration constant,
g
, or simply equal to the force of gravity acting on the object. The force of gravity acts downward.
Time is a scalar quantity (as far as we are concerned at this level). It gives information about magnitude, i.e. how much time, but no information about direction.
Volume is a scalar quantity. It refers to the amount of space that an object occupies and therefore has magnitude, but gives no information about direction.
Density is a scalar quantity, having only magnitude and giving no information about direction. We can also reason that, because density is equal to mass divided by volume and both mass and volume are scalar quantities, density must also be a scalar quantity.
Speed is a scalar quantity, having only magnitude and giving no information about direction. For example,
40
m
s
is a speed, it tells us how fast an object is traveling, but nothing abut which direction the object is traveling in. The vector counterpart to speed is velocity.
Velocity is a vector quantity. Velocities have both magnitude and direction. For example,
40
m
s
NE is a velocity.
Acceleration is a vector quantity. Acceleration has both magnitude and direction. For example,
9.8
m
s
2
downward or
−
9.8
m
s
2
vertically is an acceleration.
Force is a vector quantity. Force has both magnitude and direction. Weight is an example of force given above. Another is the force of friction, which has some magnitude and acts in the direction opposite that of motion.
Temperature is a scalar quantity. A measurement of temperature has magnitude, but gives no information about direction.
Energy is a scalar quantity. It gives information about magnitude, e.g. how much energy an object has, but none about direction.
Note that certain quantities which are alone scalars can be represented as vectors when we discuss intervals or how the quantities change (e.g. measure of increase or decrease).
Resposta:
5 m/s2

Pick a key concept that you understand well and explain it in a way that an elementary school student could understand.
Elements can be considered as building blocks of compounds similar to the building blocks present in a game.
What is an element?An element is defined as a substance which cannot be broken down further into any other substance. Each element is made up of its own type of atom. Due to this reason all elements are different from one another.
Elements can be classified as metals and non-metals. Metals are shiny and conduct electricity and are all solids at room temperature except mercury. Non-metals do not conduct electricity and are mostly gases at room temperature except carbon and sulfur.
The number of protons in the nucleus is the defining property of an element and is related to the atomic number.All atoms with same atomic number are atoms of same element.

what are some of the uses of copper?
Answer:
Explanation:
Most copper is used in electrical equipment such as wiring and motors. This is because it conducts both heat and electricity very well, and can be drawn into wires. It also has uses in construction (for example roofing and plumbing), and industrial machinery (such as heat exchangers).

A car was at rest. It then started moving forward in a straight line. The table shows the change in velocity.
What is the average acceleration of the car?
0.2 m/s2
7.5 m/s
5 m/s2
15 m/s
Answer:
5 m/s 2
Explanation:
if the car moved from 00 to 1-5 then to 2_10 you can know that it is going up in velocity but 5 a second so 5 m a second. hope this helps

Why do radio telescopes convert radio waves (analog signals) to electrical (digital) signals for analysis?
Answer:
Radio telescopes convert radio waves (analog signals) to electrical (digital) signals for analysis because radio telescopes are devices used to capture radio light waves, bring it to focus, overdraw it and use the data for processing and analysis. These radio light waves, that are raw analog signals, are converted into digital signals to create and distinguish delicate details in the universe.

Describe the composition of Granite.
Answer: Granite is a light-colored igneous rock with grains large enough to be visible with the unaided eye. It forms from the slow crystallization of magma below Earth's surface. Granite is composed mainly of quartz and feldspar with minor amounts of mica, amphiboles, and other minerals.
The chemical composition of granite is typically 70-77% silica, 11-13% alumina, 3-5% potassium oxide, 3-5% soda, 1% lime, 2-3% total iron, and less than 1% magnesia and titania.
Explanation:
Answer: Granite is a light-colored plutonic rock found throughout the continental crust, usually found in mountain areas. It consists of coarse grains of quartz, potassium feldspar, and sodium feldspar. These minerals make up more than 80% of the rock.

The internal components of an eye are Lens which are transparent, biconvex attached to the ciliary body with the cornea it refracts light.
Retina is the innermost layer of the eye, light sensitive and acts as a film of a camera, ganglion, bipolar and photoreceptor cells are present in retina.
It involve in the conversion of the image into electrical nerve impulses used for the visual perception.
Optic nerve located at the posterior portion of the eyes which carry all the nerve impulses from the retina to the brain for perception.

Answer:
Mitosis
Explanation:
Mitosis is the cell division that forms (two) daughter cells each having the same type and number of chromosomes.
Mitosis is a way of making more cells that are genetically the same as the parent cell. It plays an important part in the development of embryos, and it is important for the growth and development of our bodies as well. Mitosis produces new cells, and replaces cells that are old, lost or damaged.
