Comparing objects in a related group can reveal patterns among them. These patterns in turn can help us learn more about those o

bjects than we could by studying each individually.
With this goal in mind, watch this animation of the planets in the Solar System and select all of the following choices that describe the patterns that you've observed. As you do so, think about the implications of how the Solar System may have formed.
Choose one or more:
A. The orbits of the outer planets (those most distant from the Sun) are spaced farther apart from one another than the orbits of the inner planets.
B. Planets orbit the Sun in random directions.
C. All planets orbit the Sun in the same direction.
D. The size of all planets increases with distance from the Sun.
E. The orbits of the planets are evenly distributed in distance from the Sun.
F. All planets orbit the Sun in a roughly flat plane.
G. The closest planets to the Sun are much smaller than the planets that are farther away.
H. All planets orbit the Sun in a spherical distribution.

Answer:

C. All planets orbit the Sun in the same direction.

E. The orbits of the planets are evenly distributed in distance from the Sun.

F. All planets orbit the Sun in a roughly flat plane.

Explanation:

As we can see that due to big bang theory of planet formation we can say all planets revolve around the sun in circular orbit with almost in same plane

Size of the planets are unevenly distributed and they all revolve around the sun in same directions

so here correct options are

C. All planets orbit the Sun in the same direction.

E. The orbits of the planets are evenly distributed in distance from the Sun.

F. All planets orbit the Sun in a roughly flat plane.

A gymnast is swinging on a high bar. The distance between his waist and the bar is 0.905 m, as the drawing shows. At the top of
Citrus2011 [14]

Answer:

5.959 m/s

Explanation:

m = Mass of gymnast

u = Initial velocity

v = Final velocity

h_i = Initial height

h_f = Final height

From conservation of Energy

\frac{1}{2}mv^2+mgh_f=\frac{1}{2}mu^2+mgh_i\\\Rightarrow\frac{1}{2}mv^2+mg0=\frac{1}{2}m0^2+mgh_i\\\Rightarrow \frac{1}{2}mv^2=mgh_i\\\Rightarrow v=\sqrt{2gh_i}

h_i=2r

v=\sqrt{4gr}\\\Rightarrow v=\sqrt{4\times 9.81\times 0.905}\\\Rightarrow v=5.959\ m/s

Velocity of gymnast at bottom of swing is 5.959 m/s

When two or more different capacitors are connected in series across a potential source, which of the following statement must b
vova2212 [387]

Answer:

C. Each capacitor carries the same amount of charge.

Explanation:

When two or more different capacitors are connected in series across a potential source, each capacitor carries the same amount of charge.

In a series connected capacitor, sane amount of charge flows through the capacitors while different potential difference is passed across them.

The capacitors have the same charge as the charge flowing out directly from the potential source called emf since the emf is the driving force of charge in a circuit.

A skateboarder who travels 60 meters in 30 seconds has a speed of
natulia [17]

2m/s

Explanation:

Given parameters:

Distance traveled = 60m

time taken = 30seconds

Unknown:

Speed of skateboarder = ?

Solution:

Speed is the rate of change of distance with time taken. It is a scalar quantity that only revers magnitude;

    Speed = \frac{distance}{time}

    Speed = \frac{60}{30} = 2m/s
