Answer:

hey

A national park is a place in which you can visit.

Conservation areas are places of special architectural or historic interest where it is desirable to preserve and enhance the character and appearance of such areas.

An office heater puts out 2090 Btu (British thermal units) of energy in the form of heat per hour. Given that 1 Btu=1.055 kJ, ho
lesya692 [45]

Answer:

Total energy produced  19135.362 MJ/year

Explanation:

given details:

total energy produced = 2090 Btu per hour

1 Btu = 1.055kJ

Total energy produced per year in mega joule is = 2090*1.055 *365*24

                                                                                = 19315362 KJ/year

In mega joule per year = \frac{19315362}{1000}

mega joule per year = 19135.362 MJ/year

Black_prince [1.1K]
The speed of light is approximately 3.00 x 10^8 m/s. Then the next step is to convert m/s into km/s.To determine the time, the distance must be divided with velocity. It will take the light signal 3.3*10^-6 seconds to reach his assistant.

Calculate the normal force pushing up from the table in each example 8 kg
garik1379 [7]

The correct answer to the question is: 78.4 N.

EXPLANATION:

As per the question, the mass of the object is given as m = 8 Kg.

We are asked to calculate the normal force of the object.

The object is resting on the table.

Hence, the object pushes the table downward with a force equal to it's weight.

The table, in turn, pushes the object with the same force as given by the object, but in the upward direction.

The force given by the table on the object is known as the normal reaction of the object which acts perpendicular to the surface of the object.

Hence, the normal reaction is equal to the weight of the body.

The weight of a body is the product of it's mass with acceleration due to gravity.

So, the weight of 8 Kg object is calculated as -

Weight = mg

= 8 × 9.8 N.

= 78.4 N.

Here, g is known as acceleration due to gravity.

Hence, the normal force pushing up from the table is 78.4 N.

An incompressible fluid is flowing through a horizontal pipe with a constriction. The velocity of the fluid in the wide section
lapo4ka [179]

The Bermoulli's  equation allows us to find the pressure in the narrow part of the pipe through which water circulates is:

             P = 500 Pa

Bernoulli's equation is the work-energy relationship for fluids that are liquids and gases.

           P_1 + \frac{1}{2} \rho v_1^2 + \rho g y_1 = P2 +  \frac{1}{2} \rho v_2^2 + \rho g y_2

Where the subscripts 1 and 2 represent points of interest, P is the pressure, ρ the density of the fluid, v the velocity and y the height.

They indicate that the pipe is horizontal, that the pressure in the wide part P₁ = 200 kPa and the velocity is v₁ = 5 m / s and in the narrow part v₂=8.00 m/s, see attached.

Since the pipe is horizontal y₁ = y₂

           P₁ + ½ ρ v₁² = P₂ + ½ ρ v₂²

           P₂ = P₁ + ½ ρ (v₁² - v₂²)

Let's calculate

          P₂ = 200 10² + ½ ρ (5² - 8²)

          P₂ = 2 10⁴ - 19.5 ρ

For a specific calculation the value of the density of the fluid is needed, suppose that the fluid is water ρ = 1000 kg / m³

           P₂ = 2 10² - 19.5 1000

           P₂ = 500 Pa

In conclusion using the Bermoulli equation we can find the pressure in the narrow part of the pipe through which water circulates is:  

             P = 500 Pa
