From the given options, Iron, sodium, and calcium are metals. (option d)

A. Iron (Fe): Iron is a metal. It is one of the most abundant elements on Earth and is widely used in construction, manufacturing, and various industries due to its strength and durability. Iron is an excellent conductor of electricity, which makes it essential for electrical applications.

B. Sodium (Na): Sodium is also a metal. It is a highly reactive metal and is commonly found in compounds like sodium chloride (table salt). Sodium is an essential element for living organisms and plays a crucial role in various biological processes.

C. Calcium (Ca): Calcium is a metal. It is an important element for the human body, as it is a major component of bones and teeth. Calcium is also involved in muscle contraction, nerve function, and blood clotting. Moreover, it is used in the production of alloys and as a deoxidizer in metallurgy.

D. All of these: The correct answer is D. All of the options (iron, sodium, and calcium) are metals. They exhibit typical metallic properties such as high electrical and thermal conductivity, metallic luster, and malleability.

Answer:

You know the distance from mean position.

Answer:

the equilibrium of one wave to the crest of the same wave.

Explanation:

The amplitude of a wave corresponds to the distance between the equilibrium position of the wave and the crest of the same wave (or the distance between the equilibrium position and the through of the same wave), therefore we see that this definition corresponds to option C,

the equilibrium of one wave to the crest of the same wave.

Answer:

False

Explanation:

According to Newton's First Law of Motion, a body at rest will continue to be at rest unless another force acts on it, and a body moving at a constant speed will continue to move in a straight path unless another force acts on it.

A body must be subject to an external force in order to accelerate (or decelerate) or alter its direction of motion. Net forces or imbalanced forces are other names for external forces.

Inertia is the quality that a body possesses that prevents it from moving when at rest or from speeding up or slowing down while in motion. The mass, or quantity of substance in a body, directly relates to inertia. A body has more inertia the more mass it possesses.

According to the Second Law of Motion, if an imbalanced force applies on a body, the body will accelerate (or decelerate), changing its speed. It is possible to state that a body at rest is thought to have zero speed ( a constant speed). Therefore, an imbalanced force is any force that causes a body to move. Additionally, an imbalanced force is any force that causes a body to move slowly or quickly, such as gravity or friction. The formula below can be used to demonstrate this law.

F= ma

The imbalanced force is F.

The object's mass is m.

The force's acceleration, a, is measured.

Let b be the height of the building, and y the height of the ball at time t, given by

y = b - 1/2 gt²

where g = 9.8 m/s² is the magnitude of the acceleration due to gravity.

It takes the ball 8 s to reach the ground, at which point y = 0, so that

0 = b - 1/2 (9.8 m/s²) (8 s)²

b = 1/2 (9.8 m/s²) (8 s)²

b = 313.6 m

Answer:

Explanation:

The answer is C because the liquid has to turn into gas which the liquid has volume and a variable shape. Gas does not have volume or shape.

An object has a fixed volume and a variable shape before it changes state. After the change, it can change in both shape and volume then the change of state occurred was liquid to gas

Anything which has mass and occupies spaces is known as matter ,mainly there are four states of matter solid liquid gases, and plasma.

These different states of matter have different characteristics according to which they vary their volume and shape.

Liquid has a fixed volume but it can change its shape to any form but gases can change their volume as well as shape, therefore the correct answer is C.

Lift is generated by every part of the airplane, but most of the lift on a normal airliner is generated by the wings. Lift is a mechanical aerodynamic force produced by the motion of the airplane through the air.

Answer:

0.30 m/s²

Explanation:

Given:

v₀ = 0.2 m/s

v = 1.6 m/s

t = 4.7 s

Find: a

a = (v − v₀) / t

a = (1.6 m/s − 0.2 m/s) / 4.7 s

a = 0.30 m/s²

Answer:

h = 20.36[m]

Explanation:

To solve this problem we must calculate the perimeter (length of a circumference) of the circumference, which is denoted by the following equation:

L = 2*π*r

where:

r = radius = 0.9[m]

π = 3.1416

L = 2*(3.1416)*(0.9)

L = 5.654[m]

Now we know that the pulley or circumference had to rotate 3.6 times to get the water out of the well. In this way the depth of the well can be calculated by means of the following equation:

h = 3.6*L

h = 3.6*5.654

h = 20.36[m]
