1. Air resistance (therefore, the air density, shape (aerodynamic or not), and surface area affected
2. The gravitational acceleration constant (g = 9.8 m/s^2 on Earth)

What was the first logical for the ways things moves in the solar system?
inn [45]

Answer:

depends the ancient humans or the start of the solar system

Explanation:

if its the humans the earth was in the middle of everything.

but the beginning of the solar system lets say when earth just formed the orbits where unstable and planet ending impacts happed a lot.

ill do the proto planetary disc too

Problem 21-40a:
Greeley [361]

Answer:

Part a)

\frac{F_e}{F_g} = 2.74 \times 10^{12}

Part b)

q = 3.37 \times 10^{-4} C

Explanation:

As we know that electric force on electric charge is given as

F = qE

here we have

q = 1.6 \times 10^{-19}C

E = 153 N/C

now force is given as

F = (1.6 \times 10^{-19})(153) = 2.45 \times 10^{-17} N

Gravitational force on electric charge near surface of earth is given as

F_g = mg

F_g = (9.1 \times 10^{-31})(9.81) = 8.93 \times 10^[-30} N

now the ratio of two forces is given as

\frac{F_e}{F_g} = \frac{2.45 \times 10^{-17}}{8.93 \times 10^{-30}}

\frac{F_e}{F_g} = 2.74 \times 10^{12}

Part b)

Now the ball is balanced by the electric force and the force of gravity on it

so here we have

F_g = qE

mg = qE

(5.25 \times 10^{-3})(9.81) = q(153)

here we have

q = 3.37 \times 10^{-4} C

Choose two features of the sun and describe them.
Fofino [41]
Okay, I am going to use solar prominence and solar flares.

So, Solar Prominence is a large, bright, gaseous feature extending outward from the Sun's surface, often in a loop shape. Prominence are anchored to the Sun's surface in the photo-sphere, and extend outwards into the Sun's corona.

A solar flare is a sudden flash of brightness observed near the Sun's surface. It involves a very broad spectrum of emissions, requiring an energy release of up to 6 × 10²⁵ joules of energy (roughly the equivalent of 160,000,000,000 megatons of TNT, over 25,000 times more energy than released from the impact of Comet Shoemaker–Levy 9 with Jupiter).



Hope this helps
