The most common oxidation numbers for a given element

When the temperature in a liquid is increased this means that the average kinetic energy of the particle that composed the liquid is increased. The increase in the kinetic energy is associated with an increase in the random movement of the particles and therefore an expansion of the liquid. Therefore, what causes the liquid to expand is th thermanl expansion.

Answer:

10m

Explanation:

let's take the acceleration as a constant throughout the complete motion...

therefore first let's find the acceleration

\(s = ut + \frac{1}{2} a {t}^{2} \\ 2 = \frac{1}{2} a {1}^{2} \\ a = 4m {s}^{ - 2} \)

then we have to find v1

apply V = u + at

v = 4×1

= 4ms^-1

lets find the distance travel by the object DURING THE TIME INTERVAL 1-2

\(s = ut + \frac{1}{2} a {t}^{2} \\ s = 4 \times 1 + \frac{1}{2} \times 4 \times {1}^{2} \\ s= 6m \)

then let's find the V2

\( {v}^{2} = {u}^{2} + 2as \\ {v}^{2} = {4 }^{2} + 2 \times 4 \times 6 \\ {v}^{2} = 64 \\ v = \sqrt{64} = 8m {s}^{ - 1} \)

\(s = ut + \frac{1}{2} a {t}^{2} \\ s = 8 \times 1 + \frac{1}{2} \times 4 \times {1}^{2} \\ s = 10m \)

The distance traveled by the object during the time interval from t = 2 seconds to t = 3 seconds would be 10 meters, therefore the correct answer is option B.

There are three equations of motion given by  Newton

v = u + at

S = ut + 1/2×a×t²

v² - u² = 2×a×s

As given in the problem, an object released from rest at time t = 0 slides down a frictionless incline a distance of 2 m during the time interval from t=0 seconds to t = 1 seconds.

2 = ut + 1/2*a*t²

2 = 0 + 0.5×a×1²

a = 2 / 0.5

a = 4 meters / second²

Now to find the velocity after the 2 seconds,

v = u + at

v = 0 + 4×2

v = 8 m/s

Now by using the second equation of motion,

S = ut + 1/2×a×t²

S = 8×1 + 0.5×4×1²

S = 8 + 2

S = 10 meters

Thus, The distance traveled by the object during the time interval from t = 2 seconds to t = 3 seconds would be 10 meters, therefore the correct answer is option B.

Answer:

Gravitational forces: Earth: \(W = 650.969\,N\), Mars: \(W = 246.449\,N\), Pluto: \(W = 38.504\,N\)

Explanation:

The weight (\(W\)), measured in newtons, experimented by the person on the surface of the planet is defined by Newton's Laws of Motion:

\(W = m\cdot g\) (1)

Where:

\(m\) - Mass, measured in kilograms.

\(g\) - Gravitational acceleration, measured in meters per square second.

From Newton's Law of Gravitation we derive this expression for gravitational acceleration:

\(g = \frac{G\cdot M}{R^{2}}\) (2)

Where:

\(G\) - Gravitational constant, measured in cubic meters per kilogram-square second.

\(M\) - Mass of the planet, measured in kilograms.

\(R\) - Radius of the planet, measured in meters.

By (2) we calculate the gravitational acceleration for each planet:

Earth (\(G = 6.674\times 10^{-11}\,\frac{m^{3}}{kg\cdot s^{2}}\), \(M = 5.97\times 10^{24}\,kg\), \(R = 6.38\times 10^{6}\,m\))

\(g = \frac{\left(6.674\times 10^{-11}\,\frac{m^{3}}{kg\cdot s^{2}} \right)\cdot (5.97\times 10^{24}\,kg)}{(6.38\times 10^{6}\,m)^{2}}\)

\(g = 9.789\,\frac{m}{s^{2}}\)

Mars (\(G = 6.674\times 10^{-11}\,\frac{m^{3}}{kg\cdot s^{2}}\), \(M = 6.42\times 10^{23}\,kg\), \(R = 3.40\times 10^{6}\,m\))

\(g = \frac{\left(6.674\times 10^{-11}\,\frac{m^{3}}{kg\cdot s^{2}} \right)\cdot (6.42\times 10^{23}\,kg)}{(3.40\times 10^{6}\,m)^{2}}\)

\(g = 3.706\,\frac{m}{s^{2}}\)

Pluto (\(G = 6.674\times 10^{-11}\,\frac{m^{3}}{kg\cdot s^{2}}\), \(M = 1.25\times 10^{22}\,kg\), \(R = 1.20\times 10^{6}\,m\))

\(g = \frac{\left(6.674\times 10^{-11}\,\frac{m^{3}}{kg\cdot s^{2}} \right)\cdot (1.25\times 10^{22}\,kg)}{(1.20\times 10^{6}\,m)^{2}}\)

\(g = 0.579\,\frac{m}{s^{2}}\)

Lastly, we calculate the gravitational force for each case by (1):

Earth (\(m = 66.5\,kg\), \(g = 9.789\,\frac{m}{s^{2}}\))

\(W =(66.5\,kg)\cdot \left(9.789\,\frac{m}{s^{2}} \right)\)

\(W = 650.969\,N\)

Mars (\(m = 66.5\,kg\), \(g = 3.706\,\frac{m}{s^{2}}\))

\(W = (66.5\,kg)\cdot \left(3.706\,\frac{m}{s^{2}} \right)\)

\(W = 246.449\,N\)

Pluto (\(m = 66.5\,kg\), \(g = 0.579\,\frac{m}{s^{2}}\))

\(W = (66.5\,kg)\cdot \left(0.579\,\frac{m}{s^{2}} \right)\)

\(W = 38.504\,N\)

The relationship between total energy, kinetic energy, and potential energy can be described as follows:

Kinetic energy is the energy an object has due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity.

Kinetic energy is directly proportional to the mass of the object and to the square of its velocity: KE = 1/2 mv2. Kinetic energy is a property of a moving object or particle and depends not only on its motion but also on its mass. The higher the mass and the faster the object or particle is moving, the greater its kinetic energy will be.

Answer:

The forward motion of a body in space, such as a planet or moon, and the pull of gravity on it from another body in space.

Explanation:

Earth and many other bodies—including asteroids, comets, and the other planets—move around the sun in curved paths called orbits. Generally, the orbits are elliptical, or oval, in shape. Because of the sun’s relatively strong gravity, Earth and the other bodies constantly fall toward the sun, but they stay far enough away from the sun because of their forward velocity to fall around the sun instead of into it. As a result, they keep orbiting the sun and never crash to its surface. The motion of Earth and the other bodies around the sun is called orbital motion. Orbital motion occurs whenever an object is moving forward and at the same time is pulled by gravity toward another object.

The force acting on the system of two blocks connected by a rope passing over a pulley is -13.26 N.

The system of two blocks connected by a rope passing over a pulley are M1 and M2, where M1 rests on the triangle edge to the left of the pulley, which makes an angle of theta subscript 1 with the base of the triangle. The coefficient of friction between box M1 and the surface is mu subscript 1. M2 rests on the triangle edge to the right of the pulley, which makes an angle of theta subscript 2 with the base of the triangle.

The coefficient of friction between box M2 and the surface is mu subscript 2. The system sits atop a scalene triangle whose long edge forms the base. The pulley is attached to the apex of the triangle.M1 has a mass of 2.25 kg and is on an incline of angle 1=42.5∘ that has a coefficient of kinetic friction 1=0.205. M2 has a mass of 5.55 kg and is on an incline of angle 2=33.5∘ that has a coefficient of kinetic friction 2=0.105.The free-body diagram of M1 shows that the weight of M1 acts straight downwards (vertically) and the normal force acts perpendicular to the slope.

The force of friction opposes the motion and acts opposite to the direction of motion.M1 = 2.25 kgTheta subscript 1 = 42.5 degreesMu subscript 1 = 0.205g = 9.81 m/s²In the free-body diagram of M2, the normal force acts perpendicular to the incline of the slope, the weight of the object acts vertically downwards and parallel to the incline, and the force of friction opposes the motion and acts opposite to the direction of motion.M2 = 5.55 kgTheta subscript 2 = 33.5 degreesMu subscript 2 = 0.105g = 9.81 m/s²The tension in the string is the same throughout the rope.

a) The angle θ1 which the righthand cable makes with respect to the ceiling is  sin^(-1)(692 N / 530 N).

b) The angle θ2 which the left-hand cable makes with respect to the ceiling is  sin^(-1)(692 N / 570 N).

We may utilise the tension of the right-hand cable as well as its vertical and horizontal components to determine the angle 1. θ2 = sin^(-1)(692 N / 570 N).

We may apply the ideas of trigonometry and vector addition to address this issue.

a) The tension of the right-hand wire as well as its vertical and horizontal components can be used to determine the angle 1.

T1sin(1) calculates the vertical component of the right-hand cable's tension, which is equal to the object's weight (692 N).

T1sin(θ1) = 692 N

We may rearrange the equation to find 1:

θ1 = sin^(-1)(692 N / T1)

We can find 1 by substituting the given tension value, T1 = 530 N:

θ1 = sin^(-1)(692 N / 530 N)

b) Similarly, we can use the formula to determine the angle 2 the left-hand cable's tension and its vertical and horizontal components.

The vertical component of the left-hand cable's tension is given by T2sin(θ2), and it should also be equal to the weight of the object (692 N).

T2sin(θ2) = 692 N

To find θ2, we can rearrange the equation:

θ2 = sin^(-1)(692 N / T2)

Substituting the given tension value T2 = 570 N, we can solve for θ2:

θ2 = sin^(-1)(692 N / 570 N)
