Answer:

13.5 m

Explanation:

First, convert km/h to m/s:

64 km/h × (1000 m / km) × (1 h / 3600 s) = 17.8 m/s

Distance = rate × time

d = 17.8 m/s × 0.761 s

d = 13.5 m

Answer:

13.5 m

Explanation:

64 km * 1000 m/km

-----------------------

1 hr * 3600 s/hr

= 17.8 m/s

d = vt

= (17.8 m/s)(0.761 s)

= 13.5 m

Answer: The mass is eleven with a negative 3 charge

Explanation:

Add the protons and neutrons. This makes 11. In a stable molecule, the protons and electrons would have the same number, but this is not a  stable molecule, so subtract the number of protons from the number of electrons. this makes your negative charge. Electrons are not counted when calculating molecular mass.

An element with 5 protons, 6 neutrons and 8 electrons has a mass number of 11. The mass number is the sum of the protons and neutrons in an atom's nucleus.

The concept of the mass number in the realm of atomic structure is indeed a fundamental one, as it serves as a vital identifier for each element. The mass number of an element is the result of adding up the number of protons, which defines the element's identity, and the neutrons, found within the atomic nucleus. This addition yields the overall mass of the atom.

In response to your query, an element characterized by 5 protons and 6 neutrons indeed boasts a mass number of 11. The rationale behind this calculation is rooted in the minute mass of electrons relative to protons and neutrons. Electrons, which orbit the atomic nucleus, make a negligible contribution to the overall mass of the atom. As a result, when determining the mass number, they are rightfully omitted from the equation, and the sum of protons and neutrons stands as the decisive factor.

This core concept of mass number elucidates the distinction between various isotopes of an element, where the number of neutrons may vary, while the number of protons remains constant. It plays a pivotal role in our understanding of atomic structure and the organization of the periodic table, guiding the systematic classification of elements based on their mass characteristics.

Answer:

-40°F = -40°C

Explanation:

To convert Celsius to Fahrenheit, the following equation is used:

F = 1.8C + 32

When the temperature on the Fahrenheit scale is the same on the Celsius scale, that means F = C.  Substituting:

C = 1.8C + 32

0 = 0.8C + 32

-0.8C = 32

C = -40

Therefore -40°F = -40°C.

Answer:-40°F = -40°C

Explanation:

The inflated balloon shrinks when it is placed in an ice bath with no change in atmospheric pressure.  

Explanation:

        When the inflated balloon is subjected to an ice bath, it shrinks. This is due to the fact that smaller volume gets occupied by the air/gas inside the balloon as the temperature decreases. Hence, causes the balloon walls to collapse.  

         An ice bath also lowers the overall air temperature of the balloon inside. As the temperature decreases, the air molecules move more slowly and with lower energy. Because of the particle's lower energy, their collisions with the walls are not enough to keep the inflated balloon.

Answer:

Explanation:

givens

vf = 310 m/s

vi = 480 m/s

d = 0.1 m

formula

vf^2 = vi^2 + 2*a*d

Solution

310^2 (m/s)^2 = 480^2 (m/s)^2 + 2 * a * 0.1 meters

96100  = 230400  + 2*a * 0.1

96100 - 230400 = 2*a*0.1

-134300 = 2*0.1*a

-134300 = 0.2 *a

-134300/0.2 = a

a = -671500 m/s^2

The important thing to notice is that the acceleration is minus which means the bullet is slowing down.

Answer: [tex]1.50075*10^{-10}\ N[/tex]

Explanation:

For this exercise we need to use the Gravitational Force Formula. This is:

[tex]F_g=G(\frac{m_1*m_2}{r^2})[/tex]

Where [tex]F_g[/tex] is the gravitational force between two objects, [tex]G[/tex] is the gravitational constant ([tex]G=6.67*10^{-11}\ \frac{Nm^2}{kg^2}[/tex]) and [tex]r[/tex] is the distance between the objects.

We know that:

[tex]m_1=6.0\ kg\\\\m_2=6.0\ kg\\\\r=4.0\ m[/tex]

Therefore, in order to calculate the magnitude of the gravitational force between the two masses, we must substitute these values into the formula.

Then we get:

[tex]F_g=(G=6.67*10^{-11}\ \frac{Nm^2}{kg^2})(\frac{(6.0\ kg)(6.0\ kg)}{(4.0\ m)^2})\\\\F_g=1.50075*10^{-10}\ N[/tex]

Answer:

The answer to your question is: F = 6.69 x 10²⁰ N

Explanation:

To solve this problem we need to use the Newton's law of universal gravitation.

F = G(m1m2)/r²

where

F = ?

G = 6.674×10−11 N · (m/kg)2  is the gravitational constant

m1 = Neptune mass = 1.02 x 10²⁶ kg

m2 = Sun mass = 1.99 x 10³⁰ kg

r orbital distance among the planets = 4.50 x 10¹² m

Substitution

F = 6.674×10−11 N · (m/kg) x 1.02 x 10²⁶ kg x 1.99 x 10³⁰ kg / (4.50 x 10¹² m)²

F = 1.355 x 10⁴⁶ / 2.025 x 10²⁵

F = 6.69 x 10²⁰ N

The average magnitude of the force of gravity on Neptune due to the Sun is approximately [tex]\( 6.714 \times 10^{20} \, \text{Newtons} \).[/tex]

The average magnitude of the force of gravity F on the planet Neptune due to the Sun can be calculated using Newton's law of universal gravitation, which states that the force between two masses is proportional to the product of their masses and inversely proportional to the square of the distance between their centers. The formula is given by:

[tex]\[ F = G \frac{m_1 m_2}{r^2} \][/tex]

Plugging in the values, we get:

[tex]\[ F = (6.674 \times 10^{-11} \, \text{Nm}^2/\text{kg}^2) \frac{(1.99 \times 10^{30} \, \text{kg}) (1.02 \times 10^{26} \, \text{kg})}{(4.50 \times 10^{12} \, \text{m})^2} \] \[ F = (6.674 \times 10^{-11} \, \text{Nm}^2/\text{kg}^2) \frac{2.03 \times 10^{56} \, \text{kg}^2}{2.025 \times 10^{25} \, \text{m}^2} \] \[ F = 6.697 \times 10^{-11} \times 1.003 \times 10^{31} \, \text{N} \]\\ \[ F \approx 6.714 \times 10^{20} \, \text{N} \][/tex]

The temperature at which the sample of liquid turns to gas at 135 °C is termed as boiling point.

Answer: Option A

Explanation:

The observation of conversion of liquid to gas indicates that there is occurrence of change in the state of matter. The inter-conversion from one state to another can be done by either varying the temperature or by varying the pressure.

In this case, the liquid on heating gets converted to gaseous state after attaining a particular temperature say 135 °C. So, this process of conversion from liquid to gaseous state on heating is termed as boiling.

The temperature at which a liquid converts to gas is termed as the boiling point of that liquid.

Answer:

option a

Explanation:

Answer:

i think it's weakest

EDIT: It's net. I answered weakest but it was wrong and the correct answer was net. oops

Explanation:

if a strong force is acting on something it will push it away, meaning the object would go towards the weaker force

An object will move towards the strongest force acting on it. Option B is correct.

In physics, the net force on an object determines its motion. The net force is the vector sum of all the individual forces acting on the object. When there is a stronger force in a particular direction compared to the other forces, the object will accelerate in that direction.

Newton's second law of motion states that the acceleration of an object is directly proportional to the net force applied to it and inversely proportional to its mass. Mathematically, this can be expressed as

F=ma, where

F is the net force,

m is the mass of the object, and

a is the acceleration.

When multiple forces act on an object, they can either be in the same direction, adding up to create a stronger net force and causing acceleration, or they can be in opposite directions, balancing each other out and resulting in no net force and no acceleration (balanced forces).

In summary, an object will move towards the direction of the strongest force acting on it because that force will result in the greatest acceleration, according to Newton's second law of motion.

Answer:

because you don't got gravity in space that's why you float in space

Astronauts float in space due to being in a state of free-fall, experiencing weightlessness as a result.

Weightlessness in space occurs because astronauts and their spacecraft are in a state of free-fall, falling towards Earth without resistance. This creates the sensation of weightlessness as everything inside the spacecraft falls at the same rate, hence objects float. Weightlessness in space, often referred to as microgravity or zero gravity, occurs due to the conditions experienced by astronauts and objects in orbit around the Earth or other celestial bodies. Here's a more detailed explanation:

Free-Fall: Objects in orbit around a planet are essentially in a continuous state of free-fall towards that planet. This is because they are moving forward at a sufficient velocity to balance the force of gravity pulling them towards the planet's center. As a result, they are constantly falling towards the planet but are also moving tangentially at a high speed, causing them to continuously miss the planet.

Climate

Explanation:

I am pretty sure this is climate because climate is what the temperature over time while weather is what the temperature is today. For example, it may we windy today. That is an example of weather. It is hot in Arizona and Cold in Idaho. This is an example of climate.

Final answer:

The increase of the Earth's surface temperature by about 1 degree Fahrenheit over the past century is an example of a change in Earth's climate, which is a long-term trend, as opposed to weather which is short-term. This change is indicative of global warming and has profound effects on the environment and living organisms.

Explanation:

The National Academy of Sciences report stating that the Earth's surface temperature has risen by about 1 degree Fahrenheit in the past century is an example of a change in Earth's climate. This rise in temperature represents a long-term trend that affects ecosystems, weather patterns, and geological processes on a global scale. In contrast, weather refers to short-term atmospheric conditions. The concept of global warming is closely related to this change, as it describes the increase in Earth's average surface temperature due to activities such as burning fossil fuels which release gases that warm the planet. Notably, the increase in global temperatures has implications for habitats, species survival, and agricultural practices. Regional variations in climate change are expected, with some areas, like the Arctic, experiencing more rapid warming.

Answer:

36 km/h

Explanation:

If d is the total distance, then the time spent driving at 20 km/h is:

t₁ = (d/3) / 20

t₁ = d / 60

And the time spent driving at 60 km/h is:

t₂ = (2d/3) / 60

t₂ = d / 90

So the total time is:

t = t₁ + t₂

t = d/60 + d/90

t = d/36

The average speed is the total distance divided by total time:

s = d / t

s = d / (d/36)

s = 36

The average speed is 36 km/h.

Answer:

Two factors effecting the magnitude of the force of gravity between 2 objects are the product of their masses and square of distance between them.

Explanation:

According to Newton's law of universal gravitation

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

where F is the gravitational force, G is the universal gravitational constant and its value is 6.6743 × 10⁻¹¹ Nm²/kg₂ , m₁ and m₂ are masses of bodies and r is the distance between them.

It can be seen from the above equation that F is directly proportional to the product of the masses and inversely proportional to the square of distance between them.

                       F ∝ m₁m₂

                        F ∝ 1/r²

As far as the masses of the bodies increase, magnitude of the Gravitational force increases and if distance between them increase then Gravitational force between them decreases.

The magnitude of the force of gravity between two objects is affected by the product of their masses and inversely by the square of the distance between them, in accordance with Newton's Universal Law of Gravitation.

Two factors that affect the magnitude of the gravitational force between two objects are: the product of their masses (M1 and M2) and the square of the distance (R²) between their centers.

According to Newton's Universal Law of Gravitation, the force of gravity (Fgravity) is directly proportional to the product of the two masses and inversely proportional to the square of the distance between them.

This is mathematically represented as Fgravity = G * (M1 * M2) / R², where G is the constant of proportionality, known as the gravitational constant.

The mass of an object contributes to its gravitational pull; the more mass an object has, the greater its gravitational force. Similarly, distance plays a crucial role; as the distance between objects increases, the force of gravity decreases exponentially.

For example, if the distance between two objects is doubled, the gravitational force between them becomes one fourth of what it was at the initial distance.

Answer:

Global dependence on fossil fuels has associated social costs.

Explanation:

Increased dependence on fossil fuels reduces their availability. When the demand is high and the availability is low, the price rises. Not every nation would then be able to afford buying fossil fuels at such high costs.

Developing and underdeveloped countries would then be left behind and only the wealthy nations would be able to afford fossil fuel purchase. This would be the immediate impact of global dependence on fossil fuels.

Fossil fuels are mainly coal, petroleum and natural gas. Since fossil fuels are non-renewable in nature over exploitation may lead to fossil fuels getting exhausted.

Aristotle's theory of everything falling to its 'natural place' lasted more than 1,000 years even though it was incorrect for several reasons. One reason is that no one else pointed out the inconsistencies in the theory, as scientific methods and knowledge were limited during that time. Additionally, the idea of the Sun as the center of the solar system was not yet established, so alternative explanations were scarce.

The image result of an object reflected by a convex mirror is typically virtual, upright, and smaller. Discover how moving the object farther away from the mirror's surface affects the size of the virtual image formed behind the mirror

Explanation:

Final answer:

Convex mirrors have specific properties such as a virtual focal point behind the mirror, a negative focal length and power, and they always form virtual, upright, and smaller images compared to the object, which enables a wider field of view.

Explanation:

Properties of Convex Mirrors

A convex mirror, also known as a diverging mirror, has several distinct properties that are useful in various applications, such as security and automotive mirrors. The most notable characteristics of a convex mirror include:

The focal point (F) of a convex mirror is virtual and located behind the mirror.

Parallel rays of light after reflecting off the mirror appear to originate from this focal point.

The focal length (f) and power of a convex mirror are negative because it diverges light rays.

All images formed by a convex mirror are virtual, upright, and smaller than the object, allowing a larger area to be viewed.

Ray diagrams for convex mirrors show that all reflected rays diverge and seem to be coming from a point behind the mirror, creating a virtual image.

This set of properties makes the convex mirror a staple in situations where a wide field of view is crucial, such as security mirrors in stores and side-view mirrors on vehicles.
