Answer:

Both substance will melt and become a solution.

Explanation:

When a mixture of iron filings (black substance) and sulphur powder (yellow substance) are heated in a test tube under a bunsen burner, usually they will undergo a chemical reaction where they will melt to form a new solution of ferrous sulphide.

Thus, we can say what happens is that both substances melt to form a solution.

Answer:

The force of gravity exerts a downward force. The floor exerts an upward force. Since these two forces are of equal magnitude and in opposite directions, they balance each other.

Answer:

The number of air molecules in her lung compared with the number she had in a full breadth at the surface is;

C. Twice as many

Explanation:

The depth at which the scuba diver fills her lungs with air, d = 10 m

Pressure of fluid = Density, ρ × Acceleration due to gravity, 'g' × Depth, 'd'

Where;

ρ = 970 kg/m³

g ≈ 9.81 m/s²

∴ The pressure of the water of the 10 m water column = 970 kg/m³ × 9.81 m/s² × 10 m = 95,157 Pa

The atmospheric pressure, P₁ = 101,325 Pa

The total pressure at the 10 m depth = The atmospheric pressure + The pressure of the water of the 10 m water column

∴ The total pressure at the 10 m depth, P₂ = 95,157 Pa + 101,325 Pa = 196,482 Pa

By the combined gas law, we have;

P₁·V₁/n₁ = P₂·V₂/n₂

Where;

P₁ = The atmospheric pressure

P₂ = The pressure at 10 m depth

V₁ = V₂ = The volume of her lungs

n₁ = The number of air molecules at the surface that fills her lungs

n₂ = The number of air molecules that fills her lungs at the 10 m depth

Therefore, we have;

P₂/P₁ = n₂/n₁ × V₁/V₂

From V₁ = V₂, we have;

P₂/P₁ = n₂/n₁ × V₁/V₁ = n₂/n₁ × 1

∴ P₂/P₁ = n₂/n₁

P₂/P₁ = 196,482/101,325 ≈ 2

∴ P₂/P₁  = n₂/n₁  ≈ 2

n₂ ≈ 2 × n₁

The number of air molecules that fills her lungs at the 10 m depth, n₂ is approximately 2 times (twice) as many as the number of air molecules at the surface that fills her lungs, n₁

Therefore the correct option is twice as many molecules as she had in a full breath at the surface is required to fill her lungs at the 10 m water depth.

This question involves the concepts of pressure, the equation of state, and the number of molecules.

The number of molecules in hr breathe are "C. twice as many" as compared to the number of molecules in her lungs when she had a full breath at the surface.

According to the equation of state:

[tex]\frac{P_1V_1}{n_1}=\frac{P_2V_2}{n_2}[/tex]

where,

n₁ = no. of molecules in lungs at surface

n₂ = no. of molecules in lungs at depth

P₁ = Pressure at surface = Atmospheric Pressure = 101325 Pa

P₂ = Pressure at depth = 101325 Pa + ρgh

P₂ = 101325 Pa + (1000 kg/m³)(9.81 m/s²)(10 m) = 199425 Pa

V₁ = V₂ = V = Volume of lungs

Therefore,

[tex]\frac{(101325\ Pa)V}{n_1}=\frac{(199425\ Pa)V}{n_2}\\\\[/tex]

n₂ = 2 n₁

Answer:

Jupiter Neptune moon Uranus

Explanation:

Answer:

i) b. 14.3 Hz

ii) d. 0.4625 m/s

Explanation:

f = c / λ

f = frequency

c = speed

λ = wavelength

first question:

the given values,

λ = 2.17 m

c = 31 m/s

f = c / λ

f = 31 / 2.17

f = 14.28

∴ f = 14.3 Hz

second question:

given,

λ = 0.25 m

f = 1.85 Hz

f = c / λ

rearranging,

c = f × λ

c = 1.85 × 0.25

c = 0.4625

∴ c = 0.4625 m/s

Answer:

Time = 2.6 minutes

Explanation:

Given the following data;

Speed = 0.65 m/s

Distance = 15 meters

To find the time to get to the canteen;

Mathematically, time is given by the formula;

Time = distance/speed

Substituting into the formula, we have;

Time = 15/0.65

Time = 23.08 seconds

To minutes = 60/23.08 = 2.6 minutes

Answer:

The force exerted by the block on the floor is 38.4 Newtons

Explanation:

The given parameters are;

The area of the box in contact with the floor, A = 2.4 m²

The pressure exerted by the block on the floor, P = 16 N/m²

The force exerted by the box on the floor is given as follows;

[tex]Pressure, P = \dfrac{Force, F}{Area, A}[/tex]

∴ F = P × A

From the question, P = 16 N/m², and A = 2.4 m²

∴ F = 16 N/m² × 2.4 m² = 38.4 N

The force exerted by the block on the floor, F = 38.4 N.

Answer:

b im pretty sure (let me know if this is correct!) :)

Explanation:

Answer:

A trees food and air source would be deprived because of this. Trees need leaves to perform photosynthesis, so besides their roots soaking up water and nutrients, they wouldn't have any other form of food until those leaves grow back. If they don't and the locusts continue to eat up the tree, it will eventually starve and die.

Explanation:

Imagine the trees trunk and roots as your body and the leaves as your mouth/food source. God Forbid you catch a cold or some sickness. You probably won't have the appetite to eat. Despite that, you'll still have to. But, if you get so sick to the point that eating just makes you throw it up before your body can take in the nutrients and beneficial stuff, you will eventually get to the point where eating is nearly impossible. This will lead up to the sickness taking over your body, as there's no energy going in to help it fight it off, and you would die.
