Hii!!!
So are like properties of matter different from physical properties?

Because I’m doing an assignment and I’m not so sure!

Answer:

Materials that allow most all light to pass through them are called transparent. Examples of transparent items are glass, water, and air. Those materials that allow some light to pass through them are called translucent and include things like frosted glass and wax paper.

Answer:

They are transparent

Explanation:

Because they simple allow light to pass though instead of obstructing it

Answer:

The second type of body wave is the S wave or secondary wave, which is the second wave you feel in an earthquake. An S wave is slower than a P wave and can only move through solid rock, not through any liquid medium.

Answer:

If I were a drop of water and present in the ocean or any other aquatic system I should have moved in the water cycle as due to heats the water of the aquatic system such as the ocean becomes hot and evaporated turning into vapour, a gaseous phase of water.

Then vapour colloids with cooler air, and become cooler and convert into drops of water again which is called condensation. Drops of water again get back to the earth surface it can be in the form of rain, snow (ice form of water) termed as precipitation.

The three phases of the water cycle are

---> evaporation ---- > condensation -----> precipitation----

Answer:

The number of protons in the nucleus of the atom is equal to the atomic number (Z). The number of electrons in a neutral atom is equal to the number of protons. The mass number of the atom (M) is equal to the sum of the number of protons and neutrons in the nucleus.

Explanation:

Answer:

I. Potencia mecánica = 20000 Watts.

II. Potencia mecánica = 26 caballos de fuerza.

Explanation:

Dados los siguientes datos;

Trabajo realizado = 60000 julios

Tiempo = 3 segundos

Para encontrar el poder;

I. En vatios:

Potencia mecánica = trabajo realizado / tiempo

Potencia mecánica = 60000/3

Potencia mecánica = 20000 Watts

II. En caballos de fuerza;

1 vatio = 0.0013 caballos de fuerza

20000 Watts = 20000 * 0.0013 = 26 caballos de fuerza.

Potencia mecánica = 26 caballos de fuerza.

Una grua que efectua un trabajo de 60000 J en 3 s, tiene una potencia mecánica de 20000 W o 27 HP.

Una grua efectua un trabajo (W) de 60000 Joule en 3 segundos (t).

La Potencia mecánica (P) se define como la cantidad de trabajo realizado por unidad de tiempo.

[tex]P = \frac{W}{t} = \frac{60000J}{3s} = 20000W[/tex]

Podemos convertir 20000 W a caballos de fuerza usando el factor de conversión 1 HP = 735.5 W.

[tex]20000W \times \frac{1HP}{735.5W} = 27 HP[/tex]

Una grua que efectua un trabajo de 60000 J en 3 s, tiene una potencia mecánica de 20000 W o 27 HP.

Answer:

option B is the correct option

Explanation:

According to momentum conversion,

momentum of one car= 6600×2=13,200kgm/s

momentum of another car=5,400×(-3)=16,200kgm/s

Then,

Momentum of second car-momentum of first car

=16,200-13200

=3000kgm/s

mass of first car -mass of second car

=6600-5400

=600kg

final velocity=3000/600=2.5 m/s

Answer:

the maximum height reached by the marble is 11.84 m.

Explanation:

Given;

mass of the marble, m = 0.02 kg

extension of the string, x = 0.08 m

force applied to the string, F = 58 N

Apply the principle of conservation of energy;

elastic potential energy = gravitational potential energy

¹/₂fx = mgh

[tex]h = \frac{Fx}{2mg} \\\\h = \frac{58 \ \times \ 0.08}{2 \ \times \ 0.02 \ \times \ 9.8} \\\\h = 11.84 \ m[/tex]

Therefore, the maximum height reached by the marble is 11.84 m.

Answer:

see solution below

Explanation:

The given resistors are connected in series.

Equivalent resistance in series = 30 + 55 + 15

Equivalent resistance in series Rt = 100 ohms

Since the potential difference in the circuit = 36V

Get the current in the circuit first

I = V/Rt

I = 36/100

I = 0.36A

Get the voltage across 30ohms resistor;

V30 = 0.36 * 30

V30  = 10.8volts

Hence the voltage across the 30ohms resistor is 10.8volts

Get the voltage across 55ohms resistor;

V55 = 0.36 * 55

V55  = 19.8volts

Hence the voltage across the 55ohms resistor is 19.8volts

Get the voltage across 15ohms resistor;

V15 = 0.36 * 15

V15  = 5.4volts

Hence the voltage across the 15ohms resistor is 5.4volts

Answer: 1 st law of motion

Explanation:

Given

The bike hits the pothole and the driver flies over the handlebar. This can be explained by Newton's first law of motion. This law states that a body in the state of rest or motion will remain in that state unless an external force is applied to it.

Here, the bike instantly comes to rest by contacting the pothole which is at rest. while the driver body continues to move in forward direction and as a result it flies over the handlebars.

Answer:

[tex]\frac{X}{2}[/tex]

Explanation:

The horizontal displacement for each sphere is given by [tex]v_x\cdot t[/tex], where [tex]v_x[/tex] is horizontal velocity and [tex]t[/tex] is time. There exists no other variables that will affect the horizontal displacement (where each object lands). Since the horizontal velocity of B is exactly half of A, its horizontal displacement should also be half A, because the following factors:

-mass of spheres are the same

-time in air will be the same because both the spheres begin with no vertical velocity

-rotational inertia is negligible (implied in the problem that spheres have equal density)

Thus, if sphere A lands at some spot X, sphere B must land at some position [tex]\frac{X}{2}[/tex].

Answer:

Because cosmic disaster are so vast, astronomers use light-years as their unit of distance. One light-year is defined as the distance a beam of light travels in one year. The nearest star is a little more than 4.37 light-years away from us. When we see light from a galaxy 2 million light-years away, it has taken 2 million Earth years to reach us. Light from the Sun takes approximately 8.4269 minutes to reach us

Explanation:

i) One light-year is defined as the distance a light beam travels in a time of one Earth year. One light year is equivalent to 6 × 10¹² miles or 9.7 × 10¹² km

ii) The distance to the nearest star =  4.37 light-years

iii) When a star located in a galaxy that is 2.3 million light years away is seen, it has taken 2.3 million light years to reach us

iv) The distance of the Sun to the Earth = 151.58 million kilometers

The speed of light, c = 299792.458 km/s

The time it will take light to reach us from the Sun, 't', is given as follows;

t = 151.58 × 10⁶ km/(299792.458 km/s) ≈ 8.4269 minutes.

Answer:

Yes.

Explanation:

Yes, our body breathe out carbondioxide gas because carbondioxide gas is a waste product produced by the cells of the body during the process of respiration. The concentration of carbondioxide gas is higher in the body as compared to the outside environment and oxygen concentration is lower inside the body so diffusion occurs between the lungs and environment so the carbondioxide gas releases in the air and oxygen is trapped by the hemoglobin cells.
