swell is more regular than waves in the wind-generated area because of what?

The efficiency of the washing machine would be 7.41%.

The efficiency of any machine is a measure of the useful energy of the machine.

More specifically, the efficiency of a machine is the ratio of the input energy to the output energy.

Mathematically:

Efficiency = output energy/input energy x 100%

For a machine that uses 1039 W of energy, this simply means that the input energy of the machine is 1039 W. However, not all of this energy will be used to work.

Hence, the amount of useful energy of the machine can be calculated as:

1039 - (274+688) = 77 W

Thus:

Efficiency = 77/1039 x 100

                = 7.41 %

In other words, the efficiency of the washing machine is 7.41% when rounded to 2 decimal places.

Explanation:

red light is better able to pass completely through Earth's atmosphere and reach the moon

According to the law of conservation of angular momentum, the period of a revolving object is directly proportional to the square root of its moment of inertia. Moment of inertia depends on the mass and distribution of mass of the object, and thus, changing the revolving mass while keeping the path radius and radial force constant will affect the moment of inertia and hence the period of the revolving object. Specifically, increasing the mass will increase the moment of inertia, which in turn will increase the period of the revolving object.

This theoretical relationship has been observed experimentally in numerous situations, such as in pendulum clocks, where changing the mass of the bob affects the period of oscillation, and in rotating disks, where adding or removing mass affects the period of rotation. These observations are consistent with the law of conservation of angular momentum and confirm the theoretical prediction that increasing the revolving mass will increase the period of the revolving object.

In conclusion, changing the revolving mass while keeping the path radius and radial force constant will affect the period of the revolving object, with an increase in mass leading to an increase in period. This relationship has been observed experimentally in various contexts and is supported by the law of conservation of angular momentum.

Friction may be defined as a type of force that resists the sliding or rolling of one solid object over another through the surface that acts on it.

Friction is a force that takes place as the resistance of motion when one object rubs over another. Friction force always opposes the motion along with air resistance.

Friction can also be somehow reduced with the impact of lubrication over the rubbing surface. It is true that air resistance is greater the faster the object is traveling.

Air resistance does not depend on the blowing of the wind. It does not mean that if there is no wind blowing, the air resistance is negligible.

Answer:

The new volume of the \( NH_{3}\) sample is 3.27mL.

Explanation:

Given the following data;

Original Volume, V1 = 2.50-mL

Original Temperature, T1 = 325K

New Temperature, T2 = 425K

To find new volume V2, we would use Charles' law.

Charles states that when the pressure of an ideal gas is kept constant, the volume of the gas is directly proportional to the absolute temperature of the gas.

Mathematically, Charles is given by;

\( VT = K\)

\( \frac{V1}{T1} = \frac{V2}{T2}\)

Making V2 as the subject formula, we have;

\( V_{2}= \frac{V1}{T1} * T_{2}\)

\( V_{2}= \frac{2.50}{325} * 425\)

\( V_{2}= 0.0077 * 425\)

V2 = 3.27mL

Therefore, new volume of the \( NH_{3}\) sample is 3.27mL.

Answer:

Newton's laws of motion describe the relationship between the motion of an object and the forces acting on it. These laws can be applied to the concepts of displacement, velocity, and acceleration as follows:

-First Law: The law of inertia

This law states that an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force. This law implies that if there is no net force acting on an object, the object will remain at rest or in uniform motion in a straight line. In terms of displacement, this law means that an object's displacement will not change unless acted upon by an external force. In terms of velocity, an object's velocity will remain constant unless acted upon by an external force. In terms of acceleration, an object's acceleration will be zero unless acted upon by an external force.

-Second Law: The law of force and acceleration

This law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. In terms of displacement, this law means that the displacement of an object is directly proportional to the force acting on it. In terms of velocity, this law means that the change in velocity of an object is directly proportional to the force acting on it. In terms of acceleration, this law means that the acceleration of an object is directly proportional to the force acting on it and inversely proportional to its mass.

-Third Law: The law of action and reaction

This law states that for every action, there is an equal and opposite reaction. In terms of displacement, this law means that if an object exerts a force on another object, the other object will exert an equal and opposite force on the first object, resulting in a displacement. In terms of velocity, this law means that if an object exerts a force on another object, the other object will exert an equal and opposite force on the first object, resulting in a change in velocity. In terms of acceleration, this law means that if an object exerts a force on another object, the other object will exert an equal and opposite force on the first object, resulting in a change in acceleration.

In summary, Newton's laws of motion have numerous applications to the concepts of displacement, velocity, and acceleration. These laws can help us understand how objects move and how they respond to external forces. They are essential for fields such as physics, engineering, and astronomy, where the motion of objects is of critical importance.

Explanation:

Newton’s First Law of Motion

“An object at rest will stay at rest, and an object in motion will stay in motion unless acted on by a net external force"

This means that motion cannot change or decrease without the effect of an unbalanced force. If nothing happens to you, you will never go anywhere. If you’re going in a certain direction, unless something happens to you, you’ll always go that way forever.

That is, if the resultant force (the vector sum of the forces acting on the body) is zero, then the velocity of the object is constant. When we say that the velocity of an object is constant, we mean that both magnitude and direction are constant.

Examples

The electric fan continues to move for a period after the electricity is turned off.

Fall back forward when the stationary bus starts to move.

Newton’s Second Law of Motion

“If a force affects an object, the object gains acceleration, proportional to its strength and inversely proportional to its mass.”

Newton’s second law studies the movement of an object when external forces affect it. When a constant force affects a huge object, it causes it to accelerate, that is, to change its speed, at a constant rate.

In the simplest case, the force acting on an object at rest causes it to accelerate in the direction of the force. However, if the object is indeed in motion it may appear that the object is speeding up, slowing down, or changing its direction depending on the direction of force, directions taken by the object, and the frame of reference in which it is moving Relative to each other.

This relationship applies the principle of preserving the momentum, which is that when the sum of the resultant forces acting on the object is equal to zero, the momentum of the object remains constant. The resultant force is equal to the rate of change in the momentum.

This law also means that when two equal forces act on two different bodies, the object with greater mass will have less acceleration and slower motion, and the object with less mass has greater acceleration. For example, to illustrate:

If we have two similar engines, one for a large car and the other for a small car, then the small one will have more acceleration because its mass is less and the large one will have less acceleration because its mass is greater.

Newton’s Third Law of Motion

“For every action, there is an equal and opposite reaction.”

All forces in the universe occur in equal but oppositely directed pairs. There are no isolated forces; for every external force that acts on an object there is a force of equal magnitude but opposite direction which acts back on the object which exerted that external force.

In the case of internal forces, a force on one part of a system will be countered by a reaction force on another part of the system so that an isolated system cannot by any means exert a net force on the system as a whole. A system cannot “bootstrap” itself into motion with purely internal forces, to achieve a net force and an acceleration, it must interact with an object external to itself.

Engineers apply Newton’s third law when designing rockets and other devices, for example, the rush of gases from the rocket to the top when it ignites causes it to increase its speed.

When a person walks it affects the earth strongly and the earth also strongly affects it so both the earth and the person affect each other.

When you jump, your feet apply force to the ground, and the earth applies an equal and opposite reaction force that pushes you into the air.

When a person is in water, the water pushes the person forward while the person pushes the water back, both affect each other.

Pls mark brainlist...    A graph showing Kepler's 3rd law. ... Kepler's 3rd law is a mathematical formula. It means that if you know the period of a planet's orbit (P = how long it takes the planet to go around the Sun), then you can determine that planet's distance from the Sun (a = the semimajor axis of the planet's orbit).

Explanation:

The square of the orbital period of a planet is proportional to the cube of the semi-major axis of its orbit” That's Kepler's third law. In other words, if you square the 'year' of each planet, and divide it by the cube of its distance to the Sun, you get the same number, for all planets

There are actually three, Kepler's laws that is, of planetary motion: 1) every planet's orbit is an ellipse with the Sun at a focus; 2) a line joining the Sun and a planet sweeps out equal areas in equal times; and 3) the square of a planet's orbital period is proportional to the cube of the semi-major axis of its ..

T=2π√r3GME. For an ellipse, recall that the semi-major axis is one-half the sum of the perihelion and the aphelion.

Johannes Kepler proposed some laws based on the revolution of planets and according to his third law, the time taken for a new planet that is 3.68 x 107 km to travel around the Earth will be 0.121 years.

According to third law of Kepler, if the distance a travelled by a planet is expressed in astronomical unit and period of travel p in years then the relation between these two parameters is written as follows:

P²= a³

Kepler proposed that the planets in the solar system is revolving around the sun in an elliptical orbit and this is somewhat contradictory to the circular orbit model of Copernicus.

The distance of travel is given in 3.68 × 10⁷ km. One kilometer is 6.68 × 10⁻⁹ astronomical unit. Thus the given distance is 3.68 × 10⁷ × 6.68 × 10⁻⁹ = 0.2459 Au

Now, the time period P can be calculated as follows:

P² = (0.2459 Au)³

    = 0.0145

p   = 0.1249 years.

Therefore,  according to Kepler's third law the time taken for a new planet that is 3.68 x 107 km to travel around the Earth will be 0.121 years.

Claim: It would be easier to float in the Dead Sea than in fresh water.

Evidence: The buoyant force acting on an object depends on the density of the fluid it is immersed in. The Dead Sea has a higher density than fresh water due to the high concentration of salt and minerals, which makes it denser. The density of the Dead Sea is around 1.24 kg/L, while the density of fresh water is around 1.00 kg/L.

Reasoning: Since the buoyant force acting on an object in a fluid depends on the density of the fluid, it would be easier to float in a denser fluid than in a less dense fluid. Therefore, due to the higher density of the Dead Sea, it would be easier to float in it than in fresh water. This is supported by the fact that people are able to easily float on the surface of the Dead Sea due to its high salt concentration and density.

That is acceleration due to the horizontal component of velocity is 0

When the body is on the projectile we tend to take components on the initial velocity for ease of calculation. The velocity is then divided into its components u sinФ and u cosФ where the horizontal component of the velocity of the projectile is shown by u cosФ while the vertical component of the velocity of the projectile is shown by u sinФ

To calculate the acceleration of either component of the velocity is very easy. In this case, we use the third equation of Newton's Equation of motion.

\(V^{2}\)-\(U^{2}\)=2as

When we calculate the acceleration of the horizontal component of velocity, we find that since the velocity remains the same at both the endpoint and the start no acceleration takes place.

\(U^{2}\)\(Sin^{2}\)Ф-\(U^{2}\)\(Sin^{2}\)Ф=2as

Thus, 2as=0

That is acceleration due to the horizontal component of velocity being 0
