Answer:
There is some sort of "rollers" on the trail part that is used to make the roller coaster move when it is going up. Then because of that, the speed gets quicker when it drops down, so then it could move for a longer time until it reaches the next arch.

what is the magnitude of the eletrostatic force on an electron by another electron when they are 0.10 meter apart?
Answer:
[tex]F=2.30\times 10^{-26}\ N[/tex]
Explanation:
The distance between two electrons, d = 0.10 m
We need to find the magnitude of the electrostatic force on an electron by another electron.
The electrostatic force between two charges is given by :
[tex]F=k\dfrac{q_1q_2}{d^2}[/tex]
Substitute all the values,
[tex]F=\dfrac{9\times 10^9\times (1.6\times 10^{-19})^2}{(0.1)^2}\\\\F=2.30\times 10^{-26}\ N[/tex]
So, the magnitude of the electrostatic force between two electrons is [tex]2.30\times 10^{-26}\ N[/tex].
It is a force imposed by one charge on another as a result of the field. The magnitude of the electrostatic force will be 2.30×10⁻²⁶N.
What is the electrostatic force?
It is a force imposed by one charge on another as a result of the field. The electrostatic force produced by one line charge on another line charge is inverse of the square of the radius.
The electrostatic force is determined by the charge potency of each charge as well as the separation distance between them.
The given data in the problem is;
q=q₁=q₂ is the electric charge = 1.6×10⁻¹⁹C
r is the distance between the two charge=0.10 m
The formula for the electrostatic force is given by;
[tex]\rm F=\frac{ Kq_1q_2}{r^2} \\\\ \rm F=\frac{ 9\times 10^9 \times(1.6\times 10^{-19})^2}{(0.1)^2}\\\\ \rm F =2.30 \times 10^{-26} \ N[/tex]
Hence the magnitude of the electrostatic force will be 2.30×10⁻²⁶N.

the law of inertia states that an object in motion will stay in motion, and an object at rest will stay in rest unless acted upon by an unbalanced force which law of motion is this describing
Answer:
newton's first law of motion
Explanation:
this is because newton's first law of motion states that every object will continue in its state of rest or uniform motion in a straight line unless a resultant force acts on it so...
isn't this similar to the law of inertia?

Formula
F = m * a
Givens
F = 4900
a = 7 m/s^2
Solution
4900 = m * 7 Divide by 7
4900/7 = m
700 kg = m

What is the process of satellite orbiting?The goal of satellites is to achieve balance. They rotate around the globe quickly enough to avoid being entirely drawn down into the planet's center of gravity, yet slowly enough to avoid drifting out into space.
When a satellite is travelling at the right speed, the earth's gravitational attraction is just strong enough to keep it in place. A satellite must move quicker to maintain orbit the nearer it is to the earth's surface. Additionally, satellites' orbits are circular or elliptical due to the continual pull of the curved surface of the planet.
Therefore, gravity plays a crucial role in our daily lives, whether it's keeping us anchored to the planet's surface or keeping the satellites we use to communicate and learn more about our environment in orbit.

Explain the challenges in developing an accurate rating system for earthquakes. What kinds of variables are there?
Answer:
In turn, the main factors affecting earthquake shaking intensity are earthquake depth, proximity to the fault, the underlying soil, and building characteristics—particularly height. Let's take a look at the latter two (soil and buildings) and how they interact.
The challenge in developing an accurate rating system for earthquakes is due to complicated relationship between variables such as magnitude and intensity of earthquake.
Earthquakes are associated with magnitude and intensity.
The challenge in developing an accurate rating system for earthquake is due to complicated relationship and dependency between the magnitude and intensity of the earthquake.
Intensity of earthquake is the observed effects resulting from the earthquake such as; shaking of buildings, people etc. This intensity of the earthquake depends on the location of the observer with respect to earthquake epicenter.The magnitude of the earthquake relates to the amount of energy released during the earthquake.Thus, the challenge in developing an accurate rating system for earthquakes is due to complicated relationship between variables such as magnitude and intensity of earthquake.

What is the difference between a pure
substance, solution, and mixture?
A pure substance cannot physically be separated, and is made out of one atom (or molecule). Unlike a mixture, however, which are made out of two or more atoms or molecules. A solution in itself is the example of a mixture. (The composition of a pure substance being fixed, and a mixture's being varying depending on which.) And a solution branching off from a mixture into being either homogeneous mixtures or heterogeneous mixtures.

Calculate acceleration of a turtle going from 0.3 m/s to 0.7 m/s in 30 seconds.
Answer:
acceleration = 0.013 m/s²
Explanation:
formula for acceleration is
a = (v-u) / t
a= (0.7-0.3) / 30
= 0.013
The acceleration of a turtle going from 0.3 m/s to 0.7 m/s in 30 seconds is 0.0133m/s²
Acceleration is defined as the change in velocity of a body with respect to time. Mathematically:
[tex]a=\frac{v-u}{t}[/tex]
v is the final speed = 0.7m/s
u is the initial speed = 0.3m/s
t is the time taken = 30seconds
Substitute the given values into the formula:
[tex]a=\frac{0.7-0.3}{30}\\a=\frac{0.4}{30}\\a = 0.0133m/s^2[/tex]
Hence the acceleration of a turtle going from 0.3 m/s to 0.7 m/s in 30 seconds is 0.0133m/s²
