Answer:

Explanation:

Area of the window, A = 30 cm x 15 cm = 0.045 m²

depth, h = 1 km = 1000 m

Let P is the pressure

P = h x d x g

where d is the density of water

P = 1000 x 1000 x 9.8 = 9.8 x 10^6 Pa

Force, F = Pressure x Area

F = 9.8 x 10^6 x 0.045

F = 4.41 x 10^5 N

Answer:

F=441000\ N

Explanation:

Given:

dimension of the window, (30\times 15)\ cm

depth of window under water, d=1000\ m

<u>We know that the pressure due to liquid column is given as:</u>

P=\rho.g.d

where:

\rho= density of water

g= acceleration due to gravity

d= depth of the water column at the desired position

P=1000\times 9.8\times 1000

P=9800000\ Pa

Now the force acting on the area of the window:

F=P.A

where:

A= area of the window

F=9800000\times (0.3\times 0.15)

F=441000\ N

ANSWER 5 AND 8!!!!!;$$4$;$;
DedPeter [7]

Answer:

5 ) The mass, 6) with lubrication and using surfaces that are not rough

Explanation:

5) If two bodies are held regardless of their densities and can be combined by some chemical or physical process, the only physical property to be modified will be the mass of the resulting body.

8)

Friction depends on the contact between two surfaces and when a body has a relative motion with respect to a contact surface. In order to reduce friction the contact surface must be lubricated, also the friction depends on the coefficient of friction between surfaces and the normal force exerted by the surface parallel to the area of contact with the body. Mathematically it can be expressed with the following equation.

F_{f} = u*N\\where:\\u = friction coefficient\\N = normal force [Newtons]\\F_{f}= friction force [Newtons]

A spring is used to launch a coffee mug. The 20cm long spring can be compressed by a maximum of 8cm. The mug has a mass of 350 g
Zepler [3.9K]

Answer:

7503.13 N/m

Explanation:

Use principle of conservation of energy.

Here, energy stored in the spring due to compression shall be utilized in attaining the potential energy of the mug.

Given that,

Length of the spring = 20 cm = 0.20 m

Compression, x = 8 cm = 0.08 m

mass of the mug, m = 350 g = 0.35 kg

h = 7 m

use the expression for energy balance -

(1/2)*k*x^2 = m*g*h

=> k = (2*m*g*h) / x^2

input the values

k = (2*0.35*9.8*7) / 0.08^2

= 7503.13 N/m

The pumping of air into and out of the lungs in known as
sineoko [7]

Answer:

Respiration

Explanation:

The lungs and respiratory system allow us to breathe. They bring oxygen into our bodies (called inspiration, or inhalation) and send carbon dioxide out (called expiration, or exhalation). This exchange of oxygen and carbon dioxide is called respiration.
