Answer:
Inertia.
Explanation:
Inertia can be defined as the tendency of an object or a body to continue in its state of motion or remain at rest unless acted upon by an external force.
In physics, Sir Isaac Newton's first law of motion is known as law of inertia and it states that, an object or a physical body in motion will continue in its state of motion at continuous velocity (the same speed and direction) or, if at rest, will remain at rest unless acted upon by an external force.
For example, the inertia of an object such as a shopping cart is greatly dependent or influenced by its mass; the higher quantity of matter in a shopping cart, the greater will be its tendency to continuously remain at rest.
What happens to the particles in water as the water is heated and turns to vapor? (2 points)
Answer:
The particles will more likely to move faster since they are converted from a liquid to gas.
Rules for States of Matter:
1. Solid particles always are packed close together and don't have much space to move.
2. Liquid particles have space to move around but are still packed together, but not as close as solid.
3. Gas particles are moving freely, in fact they are in the air! Gas particles are free to move wherever. For example, the air has gas particles that are constantly bumping into each other.

A +6.33 uC charge q1 is attracted by a force of 0.115 N to a second charge q2 that is 1.44 m away. What is the value of q2?
Answer:-4.1858
Explanation: I hate Acellus
If A +6.33 μC charge q₁ is attracted by a force of 0.115 N to a second charge q2 that is 1.44 m away. then the value of q₂ = 4.23 μC.
What is coulomb's law ?Electrostatic force is a force of attraction or repulsion between two unlike or like charges respectively. when like charges come closer to each other, they gets repel by one another and it gets attracted for unlike charges. Force of attraction or repulsion between two point charges are given by coulomb's law. The force of attraction between two charges are given by coulomb's law.
the law states that the force of attraction or repulsion between two point charges is directly proportional to product of magnitude of both the charge and inversely proportional to square of the distance between them.
i.e. F ∝ q₁q₂
F ∝ 1/r²
F ∝ q₁q₂/r²
F = kq₁q₂/r²
where k is proportionality constant k = 1/4π∈₀ = 8.9×10⁹
In this problem,
Given,
q₁ = 6.33×10⁻⁶ C
F = 0.115N
r = 1.44m
q₂ = ?
putting this values in the equation,
0.115 = 8.9×10⁹×6.33×10⁻⁶ ×q₂÷1.44²
q₂ = 4.23 μC.

The speed of a wave with a frequency of 2 Hz (2/s), an amplitude of 3 m, and a wavelength of 10 m is
options:
0.2 m/s.
12 m/s.
5 m/s.
20 m/s.
Answer:
5 m/s
Explanation:
your welcome
The speed of a wave equals to Wavelength and Frequency. The SI unit of speed of wave is m/s. Thus, option D is correct.
What is speed of wave?The speed of wave is distance travelled by the wave in given time. It is related to both wavelength and frequency. Wavelength is measured in meters and frequency in hertz.
From the givens:
Frequency(f) = 2 Hz.
Wavelength(λ) = 10m.
Amplitude = 3m ( Amplitude does not affect the speed of wave)
Speed (v) = λ × f
= 10 × 2
= 20 m/s.
Therefore, the speed of the wave is 20 m/s. Hence, Option D is correct.

A student charges a balloon and then brings it near a metal sphere hanging from the
ceiling. She brings it near the sphere, but does not touch. The sphere moves toward
the balloon. What are the charges on the balloon and the metal sphere?
a) The balloon has a positive charge and the metal sphere has a negative charge.
b) The balloon has a negative charge and the metal sphere has a positive charge.
c) Both are negatively charged.
d) Both are positively charged.
Answer:
B
Explanation:
the balloon has a negative charge and the metal sphere has a positive charge
Answer: B
Explanation:
The balloon will pick up stray electrons, so it will become negatively charged. Since it is attracted to the metal sphere, the sphere must be positively charged.

A set of data is collected from a simple circuit with a
20 Ω resistor and is represented in the table.
The current at 5.0 V is
A.
The current at 15 V is
A.
Answer:
A. Recall Ohm's Law: V = IR
If V = 45 volts, and I = 5 amps, the R = V/I = 45V/5A = 9Ω
B. We know the potential difference and the resistance, both of which have good units. All we have to do is plug the known values into the equation and solve for the current:
I=15V9Ω
Thus, the electric current is: 1.67A

6. An excited dog runs full-speed toward his owner who has just returned home from
school. If he runs north along their driveway for a distance of 45 m and takes 5.2 s to get
there, what is his average velocity?
Please answer in comments with work !!:)
Answer:
v = 8.65 m/s
Explanation:
Given that,
Distance covered by the doge, d = 45 m
Time taken, t = 5.2 s
We need to find its average speed. The total distance covered divided by the total time taken is called the average speed of an object. So,
[tex]v=\dfrac{45\ m}{5.2\ s}\\\\=8.65\ m/s[/tex]
So, the average speed is 8.65 m/s.

Sound waves travel through steel railroad rails a distance of 2350 m in 0.383 s. What is the speed of sound in the rails?
(units = m/s)
Answer:
Speed of sound ways in railroad = 6,135.8 m/s
Explanation:
Given:
Distance cover by sound wave = 2,350 meter
Time taken by sound wave to cover distance = 0.383 seconds
Find:
Speed of sound ways in railroad
Computation:
Speed = Distance / Time
Speed of sound ways in railroad = Distance cover by sound wave / Time taken by sound wave to cover distance
Speed of sound ways in railroad = 2,350 / 0.383
Speed of sound ways in railroad = 6,135.77
Speed of sound ways in railroad = 6,135.8 m/s
Sound travels at different speeds in different mediums. Rank the three mediums sound can travel to from fastest to slowest.
Answer:
Sound travels at different speeds depending on what it is traveling through. Of the three mediums (gas, liquid, and solid) sound waves travel the slowest through gases, faster through liquids, and fastest through solids.
Sound waves fall into three categories: longitudinal waves, mechanical waves, and pressure waves.

Which of ONE of the following four elements has the most metallic properties?
The atomic numbers of the elements are listed below.
12
14
16
17
Answer:
12 (Magnesium- Mg)
Explanation:
Looking at the four numbers, we have:
Magnesium, Silicon, Sulfur, and Chlorine.
We can eliminate two of the answers immediately just by looking at the periodic table.
Sulfur and Chlorine are on the nonmetal side of the periodic table. So that's definitely not it. That leaves Magnesium and Silicon.
Silicon is a Metalloid. Magnesium is an Alkaline earth Metal.
Metaloids are elements that have a mix of both metal and nonmetal properties (luster, how it feels, etc.). Since it's a MIX and Magnesium is just straight METAL-
We can say Magnesium has the most metallic properties.
