Explanation:

The sun is what makes the water cycle work. The sun provides what almost everything on Earth needs to go—energy, or heat. Heat causes liquid and frozen water to evaporate into water vapor gas, which rises high in the sky to form clouds... clouds that move over the globe and drop rain and snow.

Answer:

"The sun is what makes the water cycle work. ... Heat causes liquid and frozen water to evaporate into water vapor gas, which rises high in the sky to form clouds... clouds that move over the globe and drop rain and snow. This process is a large part of the water cycle."

Explanation:

Answer:

The acceleration is g.

Taking the upward direction as positive

V = Vy y - 1/2 g t^2

Taking the downward direction as positive

V = -V y + 1/2 g t^2

One can choose either direction as positive, but the acceleration is

the same as g (it is g) while the projectile is in the air.

When a projectile reaches the highest point the vertical component of the acceleration is negative g (acceleration due to gravity). Thus, the correct option is D.

Projectile motion is the motion of an object which is thrown or projected high into the air. After the initial force applied on the object that launches the object, the object only experiences the gravitational force. The object is called a projectile and the path of the object is called trajectory.

When a projectile reaches the highest point the vertical component of the acceleration is negative g (acceleration due to gravity). When the object achieves highest point, then the vertical acceleration of a projectile is zero meter per second square when it is at the peak of its trajectory motion.

Therefore, the correct option is D.

Explanation:

The characteristics of the Big Bang allow you to find the correct answers for the different questions are:

1.  The galaxies are moving away from each other.

2.  There is a large amount of weak background radiation in the universe

3. The temperature of the universe has cooled over time

The Big Bang model says that initially the universe was born from a great initial explosion about 14 10⁹ years ago, with this idea several facts arise:

Let's apply these ideas to the different questions, to find the correct answers.

1) What phrase about galaxies provides evidence of the expansion of the universe proposed by the Big Bang

the correct answer is:

As there is no friction, the initial forces create a speed in the galaxies, therefore they must move away from each other at this speed

2) What phrases give evidence of the expansion of the universe

the correct answer is:

3) What evidence of expansion

In conclusion with the characteristics of the Big Bang we can find the correct answers for the different questions are:

    1.  The galaxies are moving away from each other.

Step 1 First Draw a Diagram.

Step 2 Identify the givens

g= -9.8 m/sec2

x0 = 0 m

Y-Yo= 80m

V0 = 800m/s -30o inclined from horizontal

Xf= ?

t = ?

Step 3  * A 2 dimensional problem so break it down into x component and y component

Step 4   x component  

x= [Vox ][cos 30o][t]

x= [800m/s][cos 30o][tsec]

x=[692.8m/s][tsec]       <---------------Need t

Step 5 y component

Y-Yo= Voy - 1/2gt2

80m= -[v][sin30o][t] -1/2gt2

1/2gt2+[v][sin30o][t]+80m=0   <-------Form Quadratic Equation

Solve for t

t=   -[v sin 30]  +/-   [(v sin 30)-(4)(1/2)(9.8)(80)]1/2

                      (2)(1/2)(9.8)

4.9 m/s to the right

Explanation:

We are going to use the conservation law of linear momentum to find her velocity. Initially, they are motionless so their initial total momentum is zero. Let's assume that anything moving to the left has a negative velocity and anything moving to the right has a positive velocity. We can write the conservation law of momentum as

[tex]0 = M_mv_m + M_wv_w[/tex]

where

[tex]M_m[/tex] = mass of the man = 55 kg

[tex]v_m[/tex] = velocity of the man = -4.3 m/s

[tex]M_m[/tex] = mass of the woman = 48 kg

[tex]v_w[/tex] = velocity of the woman

[tex]\Rightarrow 0 = (55\:\text{kg})(-4.3\:\text{m/s}) + (48\:\text{kg})v_w[/tex]

Solving for [tex]v_w,[/tex]

[tex]v_w = \left(\dfrac{55\:\text{kg}}{48\:\text{kg}}\right)(4.3\:\text{m/s}) = 4.9\:\text{m/s}[/tex]

Answer:

Static equilibrium.

Explanation:

B. A model can be used for things that are too small to see clearly

The statements which are false from the choices above are:

In scenarios of like charges, the potential energy is always positive, that is because we need to put energy in the system to bring like charges closer together.

Conversely, for unlike charges, the potential energy of the pair of unlike charges is negative, as a result of the energy expended by the system in pushing the charges away from each other.

Answer:

First scenario,

From 2nd Newton's law

F = ma

from the above eqn, it's evident

a = F/m

that is to say, acceleration is inversely proportional to mass

The greater the mass, the smaller the acceleration and the higher the acceleration, the smaller the mass.

Thus, You was in the wagon when it had the greatest acceleration because You has the smaller mass and thus the acceleration will be greater.

Second scenario,

Since Sara pulls with greater force and Force is directly proportional to acceleration according to the second Newton's law,

F = ma

then, when You is in the wagon it had greater acceleration since they have the same mass.

All the best!

The Planck model for the black body and the emission spectrum of the atoms allows to find the results for the peaks in the spectrum of stars is:

The stars are very hot celestial bodies by nuclear fusion processes, in a good approximation they approximate an ideal body that absorbs or emits all the radiation called black body.

A black body is a cavity in thermal equilibrium at a dated temperature with a small hole, this hole is the so-called black body and its emission spectrum was explained by Planck, with the assumption that the energy is

             E = h νν

Where h is Planck's constant and ν is the frequency of the radiation. In the attachment we see the emission spectrum of a black body for various temperatures.

If in the material under study we have in addition the emission characteristics of some elements, it is energy appears as peaks in the emission spectrum and as black bands o valley in an absorption spectrum, therefore the existence of the structure is in a test of the existence of chemical elements within the stars.

In the attachment we can see the spectrum of a dwarf star where we can appreciate the spectrum of the black body and the emission and absorption lines of the chemical elements inside the star.
