Answer:

The answer will be D/ Carbon is constantly recycled from dead organisms back into the

environment.

The source of most of Earth's available carbon is: carbon is constantly recycled from dead organisms back into the environment. Hence, option (D) is correct.

The carbon cycle is the exchange of carbon compounds between the earth's biosphere, geosphere, pedosphere, hydrosphere, and atmosphere.

The following are the major steps in the carbon cycle process:

Answer:

option d is the answer of given statement

The surface area of the right cone is 54π units². Hence option D correct.

The surface area of a solid object is a total area measured that the surface of the object occupies. the surface area of the cube is 6 times side², cause it has 6 faces.

The surface area is total area occupied by the surface of the object.

A cone is geometrical shape which is having circular base and cone shaped body. when a line is drawn from tip to the center of the base it will make right angle between radius and height of the cone. We can apply Pythagoras theorem to get values of radius, height and hypotenuse.

The total area of the cone is nothing but area of the base plus curved area of the body.

Hence area of the cone is,

A = πr²+πr[tex]\sqrt[]{r^{2}+h^{2} }[/tex]

Given,

r = 3

hypotenuse = [tex]\sqrt[]{r^{2}+h^{2} }[/tex] = 15

A = ?

A = π3²+π3*15

A = π (9+45)

A = 54π units²

Hence area of the cone is 54π units².

There are too many batteries in the circuit, which increased the emf of the circuit and in turn increased the current in the circuit.

The current in the circuit is determined by applying Ohms law as shown below;

V = IR

where;

I = V/R

At a constant resistance of the circuit, the current in a circuit will increase when the emf of the circuit increases.

Thus, we can conclude that, there are too many batteries in the circuit, which increased the emf of the circuit and in turn increased the current in the circuit.

Answer:

c = 3.00E8 m/s      speed of light

c = f * λ        frequency ^ wavelength

f = c / λ  = 3.00E8 m/s / .01 m = 3.00E10 / sec

f = 30,000,000,000 /sec

If the resistance of the circuit were halve and the voltage remains constant, the new current in the circuit would be 240 mA.

The current in the circuit is inversely proportional to the resistance of the circuit. This implies that the increase in the resistance of the circuit decreases the current in the circuit.

V = IR

At constant voltage;

I₁R₁ = I₂R₂

when, R₂ = 0.5R₁

I₂ = I₁R₁ /R₂

I₂ = I₁R₁ /0.5R₁

I₂ = 2I₁

I₂ = 2 x 120 mA

I₂ = 240 mA

Thus, if the resistance of the circuit were halve and the voltage remains constant, the new current in the circuit would be 240 mA.

Answer:

1.32% error

Explanation:

You can derive the relativistic kinetic energy by integrating the velocity function over a differential change in momentum. Then use integration by parts to get the answer of:

[tex]KE=mc^2[gamma-1][/tex]

Gamma is the lorentz factor equal to:

[tex]gamma=\frac{1}{\sqrt{1-(v/c)^2}}[/tex]

Therefore the relativistic kinetic energy would be:

[tex]KE=mc^2[\frac{1}{\sqrt{1-(v/c)^2}}-1][/tex]

Plug everything in to get:

[tex]KE=(17000)(3x10^8)^2[\frac{1}{\sqrt{1-(0.14c/c)^2}}-1][/tex]

[tex]KE=(17000)(9x10^{16})[\frac{1}{\sqrt{1-0.0196}}-1][/tex]

[tex]KE=1.53x10^{21}[\frac{1}{\sqrt{1-0.0196}}-1][/tex]

[tex]KE=1.52x10^{19}J[/tex]

The classical non-relativistic formula for kinetic energy is:

[tex]KE=\frac{1}{2} mv^2[/tex]

Therefore the classical kinetic energy is:

[tex]KE=1.50x10^{19}J[/tex]

Use the error percentage formula, found online if you dont recall:

[tex]error=\frac{|KE_c-KE_r|}{KE_r} \frac{100}{1} =1.32[/tex]

When an item is raised, the work is done in opposition to gravity. When an item is worked on, energy is transmitted to it, and it develops gravitational potential energy. If the same thing falls from that height, gravity must do the same amount of effort to bring it back to the Earth's surface.

Answer:

D. Push Factor

Explanation:

Weather hazards and natural disasters are horrendously negative things that people actively seek to avoid; they make people want to leave or depart from an area in order to escape them. As such, they are considered push factors.

(Weather hazards and natural disasters are not pull factors because when discussing push vs pull we are specifically describing the mentioned factor. This aspect is not considered both because the migration factor mentioned in this question actively makes people want to move to any area that avoids their issue. Remember that pull factors make people want to move to a specific place for a unique advantage, while push factors make people want to move to any general place for a common advantage.)

Answer:

420J

Explanation:

The formula (useful output ÷ total output) × 100 is used. We need to find the the useful output. So:

(useful ÷ 600) × 100 = 70(%)

We rearrange the formula so that 'useful' is the subject of the equation.

useful ÷ 600 = 0.7 {70 ÷ 100}

useful = 0.7 × 600

useful = 420J
