Answer:

100 g

Explanation:

Let the mass of density 1.2 g/cm³ be x gram and let the mass of density 1.8 g/cm³ be y gram

Applying

Density (D) = mass(m)/Volume (V)

Volume (V) = mass(m)/Density(D)

V = m/D........................... Equation 1

From the question,

x+y = 400...................... Equation 1

Volume of the liquidis

V = 400/1.6 = 250 cm³

(x/1.2)+(y/1.8) = 250

(1.8x/1.2)+y = 450............... Equation 1

Solving both equation simultaneously,

Subtract equation 1 from equation 2

x-(1.8x/1.2)+(y-y) = 400-450

x-1.5x = -50

-0.5x = -50

x = -50/-0.5

x = 100 g.

Hence the mass of the liquid of density 1.2 g/cm³ is 100 g

Answer:

7. 5 pa

8. 5 pa

9. 5 pa

10. 75 pa

11. 25 N

Explanation:

7.

P = F/ A

= 15 / 3

= 5 pa

8.

P = F/ A

= 35 / 7

= 5 pa

9.

area of floor = l × b

= 1 × 4

= 4m^ 2

P = F / A

= 20 / 4

=5 pa

10.

area in m^2 = 400/100 = 4m^2

P = F/A

= 300 / 4

= 75 pa

11.

F = P×A

= 25×1

= 25 N

just completed a assignment on this hope it helped lol.

The position of a charge an electric field that gives an electric potential energy.

Energy is the ability or capability to do tasks, such as the ability to move an item (of a certain mass) by exerting force. Energy can exist in many different forms, including electrical, mechanical, chemical, thermal, or nuclear, and it can change its form.

A potential energy that arises from conservative Coulomb forces and is connected to the arrangement of a specific set of point charges inside a given system is known as electric potential energy.

The position of a charge an electric field that gives an electric potential energy.

Answer:

Su Donarken Neden Genleşir?

Çevremizdeki maddelerin neredeyse tamamı sıcaklıkları arttığı zaman genleşir ve hacimleri artar. Bu durumu maddelerin sıcaklıklarıyla birlikte enerjilerinin de artmasıyla açıklayabiliriz.

Katı ya da sıvı haldeki bir maddenin taneciklerini bir arada tutan ana kuvvet elektromanyetik etkileşimdir. Maddelerin yoğun fazlar (katı, sıvı) oluşturmalarından da anlaşılabileceği gibi, tanecikler arasındaki çekme kuvvetleri itme kuvvetlerine baskın gelir. Isıtma sırasında maddeye verilen enerji, taneciklerin maddeyi bir arada tutan kuvvetleri kısmen de olsa yenmesini ve taneciklerin birbirinden uzaklaşmasını sağlar. Bu nedenle, genel olarak sıcaklığı artan maddelerin hacimleri de artar.

Su ise yukarıda anlatılan duruma bir istisna oluşturur. Soğutulan sıvı suyun hacmi 4ºC’ye kadar beklendiği gibi azalırken, 4ºC’den sonra artmaya başar. Hacimde soğumayla beraber yaşanan bu artış donma sırasında da devam eder. Bu olguyu açıklayabilmek için su moleküllerinin katı haldeki kristal yapısına bakmak gerekir. Sudaki hidrojen ve oksijen atomları arasında oluşan hidrojen bağları, su katı haldeyken hidrojen atomlarının farklı iki su molekülünün oksijen atomlarını birleştiren doğrusal çizgiye yakın bir nokta etrafında konumlanmasını sağlar. Oluşan bu hidrojen bağları katı halde hayli boşluklu bir yapı oluşmasına neden olur. Sıcaklık artışıyla moleküllerin enerjisi arttığı zaman ise, hidrojen bağları sebebiyle oluşan boşluklu yapı bozulur ve hacim azalır.

X-Ray

Explanation:

ON EDGE 2021

The electromagnetic wave that the CT scans are based on is called an X-ray.

When an electric field combines with a magnetic field, electromagnetic waves are created. An electromagnetic wave's magnetic and electric fields are oriented in a way that both are at right angles to each other and to the wave's direction.

Here,

A CT scan can be used to visualize almost every region of the body, and it is used to plan medical, surgical, or radiation treatments as well as detect diseases and injuries.

A narrowly focused, extremely sensitive x-ray beam that is employed in CT scanners scans the body in one particular plane. A rotating x-ray tube is used to operate the scanner as it revolves around the patient. Through the area of the body being examined, an x-ray beam is sent out in the shape of a fan.

Electromagnetic radiation includes X-rays. The highly intense X-ray photons can destroy live cells by fracturing molecules when emitted with tremendous energy.

Hence,

The electromagnetic wave that the CT scans are based on is called an X-ray.

Explanation:

Given that,

Initial volume = 60dm³

Initial pressure = 30 kPa

We need to find the new volume when pressure changes to 40 kPa (say).

We know that the mathematical relation between volume and pressure is given by :

[tex]\dfrac{P_1}{P_2}=\dfrac{V_2}{V_1}[/tex]

Put all the values,

[tex]V_2=\dfrac{P_1V_1}{P_2}\\\\V_2=\dfrac{30\times 60}{40}\\\\V_2=45\ dm^3[/tex]

So, when pressure of the gas increases, its volume get decreased.

Answer:

The force of the ball on the bat is same as the force of the bat on the ball.  

Explanation:

A bat hits the ball and the ball moves to the out filed.

According to the Newton's third law, for every action there is an equal and opposite reaction.

The action and the reaction forces acts on the two different bodies but the magnitude of the force is same.  

As the ball is hitted by the bat, the bat exerts the force on the ball and the same force is exerted on the bat by the ball according to the Newton's third law.

So, the force of the ball on the bat is same as the force of the bat on the ball but the direction of force is opposite.

Explanation:

Respuesta:

a) 12.3 m/s²

b) 153.75 m

c) 36.9 m/s

Explicación:

Paso 1: Información provista

Paso 2: Calcular la aceleración (a) del cochecito

Usaremos la segunda ley del movimiento de Newton.

F = m × a

a = F/m = 8 N / 0.650 kg = 12.3 m/s²

Paso 3: Calcular el espacio recorrido (x) en 5 segundos (t).

Usaremos la siguiente fórmula cinemática para un movimiento rectilineo uniformemente acelerado.

x = 1/2 × a × t²

x = 1/2 × 12.3 m/s² × (5s)² = 153.75 m

Paso 4: Calcular la velocidad (v) a los 3 segundos si parte del reposo

Usaremos la siguiente fórmula cinemática para un movimiento rectilineo uniformemente acelerado.

v = a × t

v = 12.3 m/s² × 3 s = 36.9 m/s

Los cálculos dados serían los siguientes:

a). Aceleración = 12,3 m / s ^ 2

B). Distancia recorrida en 5 segundos = 153,75 m

C). Velocidad en 3 segundos = 36,9 m / s

Dado que,

Fuerza aplicada = 8N

Peso de la silla de paseo en gramos = 650g

a). To find the aceleración,

[tex]F = m[/tex] × [tex]a[/tex]

[tex]a = F/m[/tex]

[tex]= 8 N/0.650 kg[/tex]

[tex]= 12.3 m/s^2[/tex]

Now,

b). :-espacio recorrido en 5 segundos y

Using the Kinematic formula:

[tex]x = 1/2[/tex] × [tex]a[/tex] × [tex]t^2[/tex]

[tex]x = 1/2[/tex] × [tex]12.3 m/s^2[/tex] × [tex](5s)^2[/tex]

= 153.75 m

c). Using the same formula,

velocidad a los 3 segundos si parte

[tex]v = a[/tex] × [tex]t[/tex]

[tex]v = 12.3 m/s^2[/tex] × [tex]3 s[/tex]

= 36.9 m/s
