D a process by which plants make their own food

Answer:

Explanation:

According to me, humans visiting an alien planet is more likely. This is because the allien planets may not have higher levels of technology.

Whereas in today's world, the technology have come to aqquire a very high position. So it likely that humans could visit the alien planets because of the technology evolved by them.

Answer:

A soccer player kicks a ball with an initial velocity of 10.0 meters per second at an angle of 30.0° above the horizontal. The magnitude of the horizontal component ofthe ball's initial velocity is which of the following?

9.8 m/s

0.50 m/s

15 m/s

7.4 m/s

Explanation:

Answer:

The answer is cool.

Explanation:

If you look at the diagram then you can see that the star being pointed to is orange-ish. Red and orange stars are the more cooler ones.

Cool is the characteristic that describes the stars indicated by the arrow in the image. Therefore, the correct option is option A.

A star is an extremely bright ball of primarily hydrogen and helium-based gas that is kept together through its own gravity. The star is supported against gravity by nuclear fusion events at its core, which also yield photons, heat, and trace quantities of heavier elements.

The star is created when hydrogen nuclei start to fuse into helium nuclei at a temperature of roughly 10 million K (18 million °F) in the gas. The expanding star's core emits energy through nuclear fusion, which eventually slows the gas cloud's collapse. Cool is the characteristic that describes the stars indicated by the arrow in the image.

Therefore, the correct option is option A.

The question does not ask for anything in particular. I will calculate the acceleration and distance.

Answer:

The acceleration of the car is [tex]-7\ m/s^2[/tex]

The distance traveled before stopping is 350 m

Explanation:

Constant Acceleration Motion

It's a type of motion in which the velocity of an object changes by an equal amount in every equal period of time.

Being a the constant acceleration, vo the initial speed, vf the final speed, and t the time, the following relation applies:

[tex]v_f=v_o+at\qquad [1][/tex]

The distance traveled by the object is given by:

[tex]\displaystyle x=v_o.t+\frac{a.t^2}{2}\qquad [2][/tex]

The car has an initial speed of v0=70 m/s when the driver sees a cow in the road and steps on the brakes with an (assumed) constant acceleration during t=10 seconds before stopping (vf=0).

With the information provided, we can calculate the value of the acceleration and the distance traveled.

Using the equation [1] we can solve for a:

[tex]\displaystyle a=\frac{v_f-v_o}{t}[/tex]

Substituting the numerical values:

[tex]\displaystyle a=\frac{0-70}{10}=-7\ m/s^2[/tex]

The acceleration of the car is [tex]-7\ m/s^2[/tex]

The distance is now calculated by using [2]

[tex]\displaystyle x=70\cdot 10+\frac{(-7)\cdot 10^2}{2}[/tex]

[tex]\displaystyle x=700-\frac{700}{2}=350\ m[/tex]

The distance traveled before stopping is 350 m

Answer:

the answer is 19 ,30 (second) times 0.5= 15

15+4= 19

After Paco drives his scoter west with an initial velocity of 4 m/s and then accelerates at 0.5 m/s² for 30 s, his final velocity is 19 m/s, so the correct option is the fourth.  

The final velocity of Paco can be calculated with the following equation:

[tex] v_{f} = v_{i} + at [/tex]

Where:

[tex] v_{f}[/tex]: is the final velocity =?

[tex]v_{i}[/tex]: is the initial velocity = 4 m/s

a: is the acceleration = 0.5 m/s²

t: is the time 30 s

Hence, the final velocity is:

[tex] v_{f} = 4 m/s + 0.5 m/s^{2}*30 s = 19 m/s [/tex]

Therefore, the correct option is 19 m/s.

Answer:

84 J

Explanation:

Work by mover:

W = Fd

W = 496 J (2.1 m)

W = 1042 J

Work by dolly and ramp:

W = Fd

W = (mg)d

W = 115 kg (9.8 m/s/s) (0.85 m)

W = 958 J

1042 J - 958 J

= 84 J

The amount of work  spent in overcoming friction is 83.65 J.

From the question,

The amount of work spent in overcoming friction = work done by the mover-potential energy of the refrigerator.

This is expressed mathematically as,

W' = Fd-mgh................... Equation 1

Where W' = work spent against friction, F = force applied, d = distance, m = mass of the refrigerator, g = acceleration due to gravity, h = height.

From the question,

Given: F = 496 N, d = 2.10 m, m = 115 kg, h = 0.85 m

Constant: g = 9.8 m/s².

Substitute these values into equation 1

W' = 496(2.1)-(115×9.8×0.85)

W' = 1041.6-957.95

W' = 83.65 J.

Hence, the amount of work  spent in overcoming friction is 83.65 J

Answer:

because plants or living things cant reflect with a red light

Explanation:

Answer:

Explanation:

Red has the longest wavelength so it has the lowest energy of any color.

Given parameters:

Force applied to the mass = 25N

Mass of the body = 1.4kg

Frictional force  = 5N

Unknown:

Acceleration of the object = ?

Solution:

The net force on the object;

     Fapplied - Frictional force = net force (m x a)

 m is the mass of the body

 a is the acceleration

Input the parameters and solve;

    25 - 5 = 1.4 x a

         1.4a  = 20

             a = [tex]\frac{20}{1.4}[/tex]   = 14.3m/s²

The magnitude of the acceleration of the object is 14.3m/s²

The idea behind capitalism is that the free market of products and ideas is owned and driven by private citizens. A capitalist society is a social order in which private property rights and the free market serve as the basis of trade, distribution of goods, and development.

Answer:

In ideal terms: In a capitalist economic system, the owner of production is the individual, and the benefactors of production are first the individual and second the society. In a socialist or communist economic system, the owner of production is the state or the society, and the benefactor is the society.

Answer:

51kg

Explanation:

So his mass is Weight/gravity=500 N / 9.8 m/s^2 = 51 kg.

Answer:

No.

Explanation:

Because the acceleration of falling objects is constant and is not affected by mass

Answer: no

The acceleration of an object is equivalent to the gravitational acceleration. The size, shape, and weight of an item are not a cause in the motion of the object. So all objects, regardless of its mass, size, or shape fall freely with the same acceleration.
