The single mark placed on the sidewalk by Julie has been acting as the reference point for detecting the motion of the snail. Thus, option D is correct.

The snail has been the shelled animal that has been mostly residing in the resting condition with limited movement. To evaluate the movement of the snail, there has been the consideration of a point that was the starting point from the movement.

The line that has been set across the sidewalk has been acting as the reference, and the distance traveled has been calculated from that point. Thus, option D is correct.

Answer:

Protons and neutrons have almost the same mass and are both located in the nucleus of the atom

Answer:

Protons and neutrons have almost the same mass and are both located in the nucleus of the atom. Protons are charged particles. Neutrons are neutral particles. ... The positive charge of the protons in the nucleus is balanced by the negative charge of the electrons.

The two terms apply to oceanic crust rather than continental crust C. Denser and D. Younger in age

Oceanic Crust Oceanic crust, extending 5-10 kilometers (3-6 kilometers) beneath the ocean floor, is mostly composed of different types of basalts. Geologists often refer to the rocks of the oceanic crust as “sima.” Sima stands for silicate and magnesium, the most abundant minerals in oceanic crust.

Oceanic crust is thin (6 km thick) and dense (about 3.3 g/cm), consisting of basalt, gabbro, and peridotite. They include oceanic sediments (e.g. radiolarites, turbidites) and oceanic crust (e.g. basalt, pillow lava).

Protons are positively charged, while electrons are negatively charged. Neutrons are electrically neutral, as the name suggests. The electric charge, noted Q , is a physical quantity.

[tex]7.408 \;X 10 ^ {-3} m^{-2} s^{-1}[/tex]  is rate of a reaction when k = 0.2, [A] = 3 M, [B] = 3 M, m = 1, n = 2 .

The rate at which the concentration of reactant or product participating in a chemical reaction alters is called the rate of reaction.

Rate of reaction = [tex]\frac{change \;in \;concentration}{time}[/tex] =  (mol/litre)/time.

m= 1 and n = 2

[tex]rate = K [A] [B]^2[/tex]

Answer:

The acid solution is a concentrated solution.

Explanation:

Acetic acid is a weak acid, because it ionizes partially in water as shown below:

CH3COOH + H2O —> H3O+ + CH3COO-

A solution containing a larger quantity of acetic acid is termed concentrated solution.

This is so because a concentrated solution is a solution that contains more of the solute than the solvent.

A solute is the substance which dissolves in the solvent.

A solvent is the substance which dissolves a solute.

In this case, acetic acid is the solute and water is the solvent.

Solution is simply the combination of solute and solvent

Solution => Solute + Solvent

More solute + Less solvent => Concentrated solution

Therefore, a solution containing a higher quantity of acetic acid ( i.e the solute) in water (i.e the solvent) is called a concentrated solution.

Answer:

One factor that affects that affects the direction of the current is the direction of motion of the wire

Explanation:

According to Fleming's right hand rule when a conductive wire which is within a circuit is moved through a magnetic field, due to Faraday's law of electromagnetic induction an electric current is induced in the wire such that the direction of motion of the wire, the direction of the magnetic field and the direction of the electric current are perpendicular to each other such that if the right hand has the thumb middle finger and the index finger held perpendicular to each other

The motion of the wire being in the direction of the wire

The first or index finger points in the direction of the magnetic field

The middle finger points in the direction of the induced electric current

Therefore, the direction of the the current depends on the direction of motion of the wire.

Answer:

Blue wave.

Explanation:

The nuclei of atoms become unstable when the repelling forces of the protons cannot be balanced by the number of neutrons in the nucleus. It then re-arranges itself randomly to a more stable configuration by emitting any of a series of particles. During radioactive decay, an atom does not collapse.

Since an atom is mostly empty space - that is it’s nucleus is relatively distant from the electron shells so, in the presence of extreme forces such as gravity inthe collapse of a large star, the inward pressures on the atom overcome the natural balance of the atomic structure and the ‘empty space’ disappears as nuclei are mashed together by the intense pressures and a neutron star is formed. Under even more external pressure, even the neutron star can collapse to form a black hole.

Answer:

B. reflection

Explanation:

Rigid transformations are methods involved in changing the dimensions or orientation of a given figure. The methods are; dilation, rotation, translation and reflection.

Reflection is the process in which a given figure is turned or flipped with respect to a point or line of reference.

In the given question,

ΔDEF ≅ ΔD'EF' (Side-Side-Side congruence property)

This implies that ΔDEF was reflected about point E to produce ΔD'EF'. Thus the required rigid transformation is reflection.

Answer:

A. increased competition for resources

Explanation:

Answer:

25 g

Explanation:

Mass percent implies the mass of solute dissolved in a solution

Mass percent = mass of solute/mass of solute + mass of solvent × 100/1

Since mass percent concentration= 20%

Mass of solvent = 100g

Let mass of solute = x

Hence;

20 = x/x +100 ×100/1

20/100= x/x + 100

0.2 = x/x + 100

0.2(x + 100) = x

0.2x + 20 = x

20 = x - 0.2x

20 = 0.8x

x= 20/0.8

x= 25 g

Answer:

727.7 torr

Explanation:

Since the gas was collected over water, it is likely to be saturated with water vapour and the total pressure is given as;

Ptotal = Pgas + Pwater

From the question;

Ptotal = 751 torr

Pgas = ?

Pwater = 23.8 torr

Making Pgas subject of equation, we have;

Pgas = Ptotal - Pwater

Pgas = 751 torr - 23.8 torr

Pgas = 727.7 torr

Answer:

The solubility of KCl is 1.93 mol/dm³

Explanation:

The information given are;

The mass of the potassium chloride, KCl = 144 g

The volume of the water solvent = 1000 cm³ = 1 dm³

The temperature of the solvent = 90 °C

The atomic mass of potassium, K = 39 u

The atomic mass of chlorine, Cl = 35.5 u

The number of moles of potassium in one mole of potassium chloride, KCl = 1 mole

The number of moles of chlorine in one mole of potassium chloride, KCl = 1 mole

The molar mass of the potassium chloride = 39 + 35.5 = 74.5 g/mol

The number of moles, n, of potassium chloride, KCl in 144 g of potassium chloride, KCl is given as follows

n = Mass/(Molar mass) = 144/74.5 = 1.93 moles

1.93 moles will dissolve in 1 dm³

Therefore, the solubility of KCl is 1.93 mol/dm³.

Answer:

0.020g de sulfato de plomo se requieren

La concentración de la solución diluida es de 3ppm

Explanation:

Las partes por millón (ppm) son definidas como:

miligramos soluto / 1L solución.

Si deseas preparar una solución a 100ppm de sulfato de plomo (II) necesitas 100mg de este sulfato en 1L. En 200mL = 0.200L vas a necesitar:

0.200L × (100mg / 1L) = 20mg de sulfato de plomo (II).

Como 1000mg = 1g,

20mg × (1g / 1000mg) = 0.020g de sulfato de plomo se requieren.

Ahora, se van a tomar 30mL de esta solución y se diluirán a 1000mL. Se diluye la solución:

1000mL / 30mL = 33.33 veces.

Como la solución inicial es de 100ppm, esta dilución genera una solución de concentración:

100ppm / 33.33 = 3ppm
