The particles of a substance in which state of matter have the least energy?

A. Liquid
B. Solid
C. Gas
D. Vapor

Answer:

A pair of oxygen atoms is a molecule of oxygen. A molecule is the smallest particle of a substance that exists independently. Molecules of most elements are made up of only one of atom of that element. Oxygen, along with nitrogen, hydrogen, and chlorine are made up of two atoms.

Incomplete question. However, I inferred you want an explanation for the assertion above.

Explanation:

Interestingly, humans have a diverse thought process, it is this diversity that makes part of us want to control how others behave forgetting that humanity is part of nature; which is also diverse.

For example, we know humans do not wings to fly, it is not part of our nature. Similarly, others do not display affection the same we do today and are so we need to respect their nature; their personality.

Answer:

684.5 is the weight on mars and 1813 on earth

Explanation:

185*3.7=684.5 185*9.8=1813 you multiply for earth by 9.8 because that's the gravity on earth and you multiply by 3.7 because that's the gravity on mars

684.5 is the weight on mars and 1813 on earth

Weight on mars:

[tex]= 185 \times 3.7[/tex]

= 684.50

And, weight on earth is

 [tex]= 185\times 9.8[/tex]

=1813

Question:

What happens to electrical energy that is used by objects in our homes? (1 point)

a It is absorbed by batteries.

b It is destroyed.

c It is stored in solar panels.

d It is transformed into other forms of energy.

Answer:

D

d. It is transformed into other forms of energy.

When electrical energy is used by objects in our homes, it is transformed into other forms of energy depending on the specific device or appliance. For example:

This transformation of electrical energy into other forms is governed by the principles of conservation of energy, which state that energy cannot be created or destroyed, only converted from one form to another. So, while electrical energy is consumed and "used up" by the devices in our homes, it is not destroyed but rather converted into different forms of energy that serve various purposes.

Answer:

height = 1.5 x 10⁶ m = 1500 km

Explanation:

We can use the formula of gravitational force from the Newton's Gravitational Law:

[tex]F = \frac{Gm_{1}m_{2}}{r^2}[/tex]

where,

F = Gravitational Force = 6.6 x 10³ N

G = Universal Gravitational Constant = 6.67 x 10⁻¹¹ N.m²/kg²

m₁ = mass of earth = 6 x 10²⁴ kg

m₂ = mass of satellite = (1.02 tons)(1000 kg/1 ton) = 1.02 x 10³ kg

r = distance between center of earth and satellite = ?

Therefore, using these values in the equation, we get:

[tex]6.6\ x\ 10^3\ N = \frac{(6.67\ x\ 10^{-11} N.m^2/kg^2)(6\ x\ 10^{24} kg)(1.02\ x\ 10^3\ kg)}{r^2}\\\\r^2 = \frac{(6.67\ x\ 10^{-11} N.m^2/kg^2)(6\ x\ 10^{24} kg)(1.02\ x\ 10^3\ kg)}{6.6\ x\ 10^3\ N}\\\\[/tex]

[tex]r = \sqrt{61.84\ x\ 10^{12}\ m^2 }[/tex]

[tex]r = 7.86\ x\ 10^6 m[/tex]

The distance between center of earth and the satellite is equal to the sum of height of satellite and radius of earth:

[tex]r = height + radius\ of\ earth\\7.86\ x\ 10^6 m = height + 6.36\ x\ 10^6 m\\height = 7.86\ x\ 10^6 m - 6.36\ x\ 10^6 m[/tex]

height = 1.5 x 10⁶ m = 1500 km

Explanation:

Answer:

The maximum radius the asteroid can have for her to be able to leave it entirely simply by jumping straight up is approximately 1782.45 meters

Explanation:

Whereby the height the astronaut can jump on Earth = 0.500 m, we have the following kinematic equation;

v² = u² - 2·g·h

Where;

v = The final velocity

u = The initial velocity

g = The acceleration due to gravity ≈ 9.8 m/s²

h = The height she jumps

At the maximum height, [tex]h_{max}[/tex] = 0.500 m, she jumps, v = 0, therefore, we have;

0² = u² - 2·g·[tex]h_{max}[/tex]

u² = 2 × 9.8 × 0.5 = 9.8

u = √9.8 ≈ 3.13

u = 3.13 m/s

Her initial jumping velocity ≈ 3.13 m/s

Escape velocity, [tex]v_e = \sqrt{\dfrac{2 \cdot G \cdot M}{r} }[/tex]

Where;

M = The mass of the asteroid

G = The Universal gravitational constant = 6.67408 × 10⁻¹¹ m³/(kg·s²)

r = The radius of the asteroid

The average density of the Earth = 5515 kg/m³

The mass of the asteroid, M = Density × Volume = 5515 kg/m³× 4/3 × π × r³

The escape velocity, she has, [tex]v_e[/tex] ≈ 3.13 m/s is therefore;

[tex]3.13 = \sqrt{\dfrac{2 \times 6.67408 \times 10^{-11} \times 5515 \times \frac{4}{3} \times \pi \times r^3}{r} } = r \times \sqrt{3.084 \times 10^{-6}}[/tex]

[tex]r = \dfrac{3.13}{ \sqrt{3.084 \times 10^{-6}}} \approx 1782.45[/tex]

Therefore, the maximum radius of the asteroid can have for her jumping velocity to be equal to the escape velocity for her to be able to leave it entirely simply by jumping straight up = r ≈ 1782.45 meters.

The statement that belongs to region X is  option (d)

(d) The main charge carriers are negative electrons

The reason for the selection is as follows;

The given region marked X belong to the NPN Transistor that has the following characteristics

The NPN transistor consist of a P-Type semiconductor sandwiched between two N-Type semiconductors

The charge carriers in a NPN transistor are negative electrons, while the charge carriers in a PNP transistor are holes

NPN transistor is the most commonly used type of BPT transistor due to the high mobility of electrons compared to holes

Electrons are passed from the emitter to the collector in an NPN transistor

Therefore, the statement that belongs only of the region marked X is that the main charge carriers are negative electrons

The student hears the wave that is transmitted by the desk

Explanation:

Mechanical waves need a material medium to be able to be transmitted, in the case of sound waves, one of the most common media is air, but it is also transmitted in other media in this case, stationery is transmitted.

The student hears the wave that is transmitted by the desk

The speed of the wave is proportional to the density of the material, so the wave that the student hears arrives much faster through the desk than through the air

Answer:

The greater wax moth developed the ability to hear frequencies up to 300kHz to trick bats, their chief predators.

Explanation:

Dogs commonly listen to frequencies of about 30 kHz. But nothing matches the moths 300-kHz maximum. Since there aren't any noises in an environment that get close, scientists hypothesize that greater wax moths developed super sensitive hearings to trick bats, their chief predators. it can hear wavelengths up to 300 kHz, well exceeding the range of any other creature and higher than any bat can sound.

Answer:

v = 28.87 m/s

Explanation:

Given that,

Mass of a cubic tiger, m = 146 kg

Initial velocity, u = -22 m/s

Acceleration, a = -0.43 m/s²

Distance moved, s = -407 m

We need to find the final velocity of the tiger. Using third equation of motion to find it. Let v is the final velocity of the tiger.

[tex]v^2-u^2=2as\\\\v^2=(-22)^2+2\times (-0.43)\times (-407)\\\\=28.87\ m/s[/tex]

So, the final velocity of the tiger is 28.87 m/s.

Good Luck!!

The child's radial/centripetal acceleration at the lowest point of the swing is

a = (3.00 m/s)² / (7.00 m) = 1.29 m/s²

By Newton's second law, the tension in the rope is

T = (3.5 kg) (1.29 m/s²) = 4.5 N

(Does the question really say the child's mass is 3.5 kg? That's little more than the average mass of a newborn, about 3.3 kg. Not exactly a good idea to put a newborn on a swinging rope...)
