Answer:

The sun generates energy from a process called nuclear fusion. During nuclear fusion, the high pressure and temperature in the sun's core cause nuclei to separate from their electrons. Hydrogen nuclei fuse to form one helium atom. ... The sun provides more energy in an hour than the United States can use in a year!

Explanation:

Answer:

Explanation:

Like most stars, the sun is made up mostly of hydrogen and helium atoms in a plasma state. The sun generates energy from a process called nuclear fusion. During nuclear fusion, the high pressure and temperature in the sun's core cause nuclei to separate from their electrons. ... Yet this amount of energy is enormous.

Explanation:

if you have a force at an angle in order to get it with the horizontal you get the Force times cosine the angle and if you want it with the vertical you got the Force times sine the angle

Answer:

[tex]2\times 10^{8}\ \text{m/s}[/tex]

Explanation:

[tex]n[/tex] = Refractive index of glass = 1.5

[tex]c[/tex] = Speed of light in vacuum = [tex]3\times 10^8\ \text{m/s}[/tex]

Refractive index is given by

[tex]n=\dfrac{c}{v}\\\Rightarrow v=\dfrac{c}{n}\\\Rightarrow v=\dfrac{3\times 10^8}{1.5}\\\Rightarrow v=2\times 10^{8}\ \text{m/s}[/tex]

The speed of light in the glass is [tex]2\times 10^{8}\ \text{m/s}[/tex].

Answer: This is simply false.

Explanation:

Newton's Law of inertia is NOT sufficient to cause a planet to orbit the sun because gravity  already does that.

Answer:

Decaying

Explanation:

Dead plants and animals go through decaying process as their body is broken down into many pieces which later becomes the part of soil. Decaying process is done by decomposers like bacteria, fungi, etc.

Answer:

Veterbrate

Explanation:

Oxygen has an atomic number 8, because it has 8 protons and 8 electrons.

The first shell of an atom can hold up to 2 electrons but oxygen has 8 electrons, in that eight electrons 2 are in the first shell, so it has 6 more electrons left. The second shell can hold up to 8 electrons, oxygen has only 6 more electrons after the first shell is full, so it will have 6 electrons in the second shell

From this we know that oxygen has 2 shells so it is in period 2, and by counting from left to right, the sixth box in period 2 lies on group 16

Therefore Oxygen lies on group 16 and period 2

Answer: This is MECHANICAL type of weathering.

Explanation:

Weathering is defined as the process by which rocks breakdown into smaller quantities due to different atmospheric and biological activities.

There are different types of weathering which include:

--> MECHANICAL WEATHERING: This type of weathering is also called physical weathering. Here, rocks are being broken down into smaller pieces but the mineral composition of the rock remains the same. This type of weathering can occur in two ways:

• By Ice wedging: this is one of the easiest ways rocks can be broken into smaller pieces. It occurs at the earth polar regions (climate that regularly cycles above and below the freezing point) and in areas of higher elevations such as the mountains. Ice wedging of rocks occurs when water seeps into cracks, it freezes and expands. This results in wedging (splitting) the rocks apart with repeated freezing.

• By Abrasion: this is another form in which mechanical weathering occurs. Abrasion occurs when strong winds carrying pieces of sand sandblast mountain surfaces. Also moving water, gravity, biological activities can cause abrasion of rock surfaces leading to its weathering.

Therefore, small pieces of sand hitting the side of a mountain and weathering the rock is an example of mechanical weathering by abrasion.

Answer:

Kinda? Depends what the question is fully asking

Explanation:

Acceleration is a change in velocity. So I guess if the velocity of something is -2 m/s and its positively accelerating at a value of +1 m/s, then that means every second its velocity changes by +1m/s.

So that -2 m/s thing after one second will be going -1 m/s.

After another second it'll be going 0 m/s.

After another itll be going +1 m/s and so on.

So at one point for a brief moment, it can have an acceleration but be at 0 m/s velocity.

Answer:

Presión = 175,97 N/m²

Explanation:

Dados los siguientes datos;

Peso del alumno (fuerza) = 725N

Área de zapatos = 412 cm² a metros cuadrados = 412/100 = 4.12 metros

Para encontrar la presión, usaríamos la siguiente fórmula;

Presión = fuerza / área

Presión = 725 / 4.12

Presión = 175,97 N/m²

The correct answer is sea breeze

Answer:

Land breeze.

Explanation:

The breeze that blows from the land toward the sea after sunset. The land cools more quickly than the ocean, cooling the air above it. The warmer air above the water continues to rise, and cooler air from over the land replaces it, creating a breeze.

Answer:

a)   τ₁ = 660 N m,  b)  τ’= 686 N m,  c)    F = 623.6 N

Explanation:

a) For this exercise let's use the concepts of torque and rotational balance.

For this we set a reference system at the base and assuming that the counterclockwise rotations are positive

where the force F = 600 N, the distance to the axis is x = 1.1 m, the mass of the system m = 70g and the weight is placed at the point of the center of  gravity x_{cm} = -1.0 m

The torque at the front is

          τ₁ = F x

          τ₁ = 600 1.1

          τ₁ = 660 N m

b) let's write the rotational equilibrium condition

           ∑ τ = 0

           τ'- W x_{cm} = 0

           τ ’= mg x_{cm}

            τ’= 70 9.8 1.0

            τ’= 686 N m

c) the greatest force Matt can apply

           τ’= F x

           F = τ’/ x

           F = 686 / 1.1

           F = 623.6 N

Answer:

g = 4,10 m/s

Explanation:

Este es un ejercicio de péndulo simple, donde la velocidad angular esta dada por

          w = [tex]\sqrt{ \frac{g}{L} }[/tex]

la velocidad angular esta relacionada con el periodo

         w =2π/T

sustituimos

         [tex]\frac{2\pi }{T} = \sqrt{ \frac{g}{L} }[/tex]2pi/T = Ra g/L

         T² = [tex]4\pi ^2 \frac{ L}{g}[/tex]

          g = [tex]4\pi ^2 \ \frac{L}{T^2}[/tex]

el periodo es el tiempo de una oscilación completa, osea desde el punto donde se suelta hasta que regresa al mismo punto, en este caso tenemos medio periodo, desde donde se suelta hasta donde se detiene

       T/2 = 1,9

       T = 2  1,9

       T = 3,8 s  

calculemos

        g = 4π²  1,5 /3,8²

        g = 4,10 m/s

Explanation :

F1 = 20 N

F2 = 30 N

F = F2 - F1 = 30 - 20 = 10 N

Answer:As we galn mass, the force of gravity on us increases.

Explanation:

Answer:

Increasing the sample size could make a small difference between means reach statistical significance because;

a) As N increases the standard error gets smaller reflecting less variability in sample means, which allows greater sensitivity to detect small but significant differences

Explanation:

The p-value of a test statistic is used to express the level of significance of the test result. A significant result is typically considered as one with a small p-value of less than or equal to 0.05 at which point we reject the null hypothesis

The p-value can be made smaller by either

1) Increasing the size of the sample (N)

2) Decreasing the standard error

3) Increasing the difference between the hypothesized parameter and the statistic of the sample

The standard error, SE, is given as follows;

[tex]SE = \dfrac{\sigma}{\sqrt{N} }[/tex]

Where;

σ = The standard deviation of the sample

n = The sample size

Therefore the standard error decreases, gets smaller,  with increasing sample size, N

Therefore, the small difference between the sample mean could reach statistical significance with a large sample because as N increases the standard error gets smaller reflecting less variability in sample means, which allows greater sensitivity to detect small but significant differences.

Answer:

equal to 1

Explanation:

When any ray of light falls or strikes on a surface, the ray is reflected back and the angle of reflection is equal to angle of the incidence, where both the angles are always measured from the path of light that is normal to surface of the point at which the ray of light strikes the surface. This is called as the laws of reflection of light.

And therefore, the ratio of the angle of incidence to the angle of reflection is always equal to 1.

Answer:

9.9 m

Explanation:

From the question given above, the following data were obtained:

Force (F) = 40 N

Workdone (Wd) = 395 J

Height (h) =?

The height can be obtained as follow:

Potential energy = mgh = Fh

395 = 40 × h

Divide both side by 40

h = 395 / 40

h = 9.9 m

Thus, the height is 9.9 m.

The answer is A. Type of coke (Diet or Coca-Cola) is the correct answer.
