MatroZZZ [7]2 years ago
7 0

Answer:

Explanation:

Speed and medium are properties of a wave which is in common within an area of the spectrum of visible light. i.e;

Their medium of propagation

They both travel at the same speed ( speed of light )

The properties mentioned above are properties that define that wave is found within an area spectrum for visible light.

Diano4ka-milaya [45]

Answer: You don't do work.

Explanation: If you don't do the work you don't have to ask this question. With work comes labor. With labor comes change. With change comes resistance and people do not like change. IT causes anger, so if you stop doing work and stick to the important supply like food, water, and shelter you don't have to go through the trouble of this and we can live in a peaceful environment for this world to be better than it is. People do to much, it's a natural fact but you can change the entire picture. If you read all of this thank you for accepting the fact of life.

50 points and brainleist
Elodia [21]

Answer:

Because it makes our lives easier.

Explanation:

When we talk about nonrenewable resources, it's usually fossil fuels that derive from crude oil. After dividing the useless crude oil into different fractions, you get gases, petrol, kerosene, diesel, fuel oil and bitumen. Each fraction has their own unique purpose i.e: petrol as a fuel for cars.

We use plastic bags for our ease. They consist of a long chain of 'alkenes' that's called poly(ethylene). The long chain was made by smaller molecules from crude oil.

When these bags are burnt for disposal, they release toxic fumes. One being carbon monoxide.

A solid weighs 237.5 g in air and 12.5 g in a liquid in which it is wholly submerged. The density of the liquid is 900 kg/m³.
djyliett [7]

(i) The density of the solid is 950 kg/m³

(ii) the density of another liquid in which the same solid would float is 200 kg/m³

The given parameters;

mass of the solid in air, Ma = 237.5 g

mass of the solid in liquid, Ms = 12.5 g

density of the liquid, \rho_l = 900 \ kg/m^3

(i) The density of the solid is calculated as follows;

Weight in air - Weight in liquid = upthrust

\frac{\rho_o}{\rho_l}  = \frac{Ma}{M_a - Ms} \\\\\frac{\rho_o}{900}  = \frac{237.5}{237.5 - 12.5}\\\\\frac{\rho_o}{900}  =1.0556\\\\\rho_o = 1.0556 \times 900\\\\\rho_o = 950 \ kg/m^3

(ii) the density of another liquid in which the same solid would float with one-fifth of its volume exposed above the liquid surface.​

This is a low density liquid, because one-fifth of the solid is above the liquid surface while four-fifth is below the liquid surface.

the specific gravity of the liquid = ¹/₅ = 0.2

density of water , \rho_w = 1000 \ kg/m^3

S.G = \frac{\rho_l}{\rho_w} \\\\0.2 = \frac{\rho_l}{1000} \\\\\rho_l = 0.2 \times 1000\\\\\rho_l = 200 \ kg/m^3

Thus, the density of another liquid in which the same solid would float is 200 kg/m³

se lanza un cuerpo desde el origen con velocidad horizontal de 40 m/s, y con un ángulo de 60º. calcular la máxima altura y el al
EastWind [94]

Answer:

1. h = 244.8 m    

2. x = 564.8 m  

Explanation:

1. La altura máxima se puede calcular usando la siguiente ecuación:

v_{f}^{2} = v_{0}^{2} - 2gh     (1)                        

Where:

v_{f_{y}}: es la velocidad final = 0 (en la altura máxima)  

v_{0_{y}}: es la velocidad inicial horizontal en "y"

g: es la gravedad = 9.81 m/s²          

h: es la altura máxima =?

La velocidad incial en "y" se puede calcular de la siguiente manera:

tan(\theta) = \frac{v_{0_{y}}}{v_{0_{x}}}

v_{0_{y}} = tan(60)*40 m/s = 69.3 m/s                    

Resolviendo la ecuación (1) para "h" tenemos:

h = \frac{v_{0_{y}}^{2}}{2g} = \frac{(69.3 m/s)^{2}}{2*9.81 m/s^{2}} = 244.8 m          

2. Para calcular el alcance horizontal podemos usar la ecuación:

x = v_{x}*t

Primero debemos encontrar el tiempo cuando la altura es máxima (v_{f_{y}} = 0).

v_{f_{y}} = v_{0_{y}} - gt    

t = \frac{v_{0_{y}}}{g} = \frac{69.3 m/s}{9.81 m/s^{2}} = 7.06 s      

Ahora, como el tiempo de subida es el mismo que el tiempo de bajada, el tiempo máximo es:

t_{m} = 2*7.06 s = 14.12 s          

Finalmente, el alcance horizontal es:

x = 40 m/s*14.12 s = 564.8 m                                                            

Espero que te sea de utilidad!
