Answer:

The ball is rolling at a speed of 0.02 meter per second.

Step by step explanation:

We are given that there is a 800 gram bowling ball rolling in a straight line. If its momentum is given to be 16 kg.m/sec, we are to find its velocity.

For this, we will use the formula of momentum.

Momentum = mass × velocity

16 = 800 × velocity

Velocity = 16/800 = 0.02 meter per second

1.41176471

Explanation:

r=v/I plug it into the formula

Speed of mechanical wave (sound wave) is given by the formula

[tex]v = \sqrt{\frac{E}{\rho}}[/tex]

here we can say that speed of sound wave depends on two factors

1). E = elasticity

2). [tex]\rho[/tex] = density

also we can have the string wave speed given by the equation as

[tex]v = \sqrt{\frac{T}{\mu}}[/tex]

here we can say it will depends on

1). T = tension in the string

2)[tex]\mu[/tex] = linear mass density

Also we will have the speed of sound in gases given as

[tex]v = \sqrt{\frac{\gamma RT}{M}}[/tex]

here it depends on two factors as

1). [tex]\gamma[/tex] = Type of gas

2). T = temperature of gas

The speed of a mechanical wave is predominantly determined by the medium through which it travels and the energy of the wave itself, which is dependent on its amplitude and frequency. Changes in these factors will result in changes in the speed of the wave.

The two primary factors that can alter the speed of a mechanical wave are the characteristics of the medium through which it is traveling and the energy of the wave itself, which is related to its amplitude and frequency. For instance, the speed of sound waves can change when they travel from one medium to another, however the frequency typically remains constant. Therefore, if the speed changes but the frequency remains the same, the wavelength has to adjust accordingly.

For example, in a guitar, the strings vibrate to produce sound. The speed of the waves on the strings, along with the wavelength, determines the frequency of the sound that we hear. All strings may be made of similar material, but they have different thicknesses and thus, different linear densities. The linear density is defined as the mass per length, and can influence the speed of the wave.

Ultimately, waves are energy in motion and their speed can be affected by any change in the medium they travel through or the energy they carry.

Answer:

Squats involve flexion (forward motion) and extension (backward on the way up), so would fit into the sagittal plane. Frontal plane motion would include leaning from left to right as in sidebends and lateral raises, or perhaps you might picture jumping jacks for a good image of movement along the frontal plane.

The Sagittarius plane, or sagittal plane, movements occur side to side, frontal (coronal) plane movements happen front to back, and transverse plane movements are rotational, involving the upper and lower sections of the body. An MRI scanner moves in corresponding directions to produce images in these planes.

The movements associated with the sagittal plane, frontal plane (coronal plane), and transverse plane are crucial in anatomical and clinical settings such as MRI scanning, which uses these planes to create sectional images of the body.

The Sagittarius plane, or more accurately referred to as the sagittal plane, is a vertical plane that divides the body into right and left portions. An MRI scanner would move along the medial-lateral axis (side to side) to produce images in the sagittal plane. Flexion and extension movements, such as bending and straightening of the joints, occur within this plane.

The frontal plane, also known as the coronal plane, splits the body into front (anterior) and back (posterior) sections. To capture images in the frontal plane, an MRI scanner would need to move in an anterior-posterior direction (front to back).

The transverse plane divides the body into upper and lower parts, cutting across the long axis at a right angle to both the sagittal and frontal planes. Rotational movements, like rotating the head or the trunk of the body, take place in this plane.

Answer:

The difference in potential at two points in a wire causes electric current in a wire.

Explanation:

Electric Current:

The flow of Electric charges is called Electric Current.

An electric current is said to exist when there is a net flow of electric charge through a region. In electric circuits this charge is often carried by electrons moving through a wire.

Electrons move in a wire from lower potential to higher potential because, positive charge attracts the negative charge and causes it to move towards itself.

Answer:

25 cm

Explanation:

about the size of a basket ball

vf = 10 m/s. A ball with mass of 4kg and a impulse given of 28N.s with a  intial velocity of 3m/s would have a final velocity of 10 m/s.

The key to solve this problem is using the equation I = F.Δt = m.Δv, Δv = vf - vi.

The impulse given to the ball with mass 4Kg is 28 N.s. If the ball were already moving at 3 m/s, to calculate its final velocity:

I = m(vf - vi) -------> I = m.vf - m.vi ------> vf = (I + m.vi)/m ------> vf = I/m + vi

Where I 28 N.s, m = 4 Kg, and vi = 3 m/s

vf = (28N.s/4kg) + 3m/s = 7m/s + 3m/s

vf = 10 m/s.

The average kinetic energy of particles in an object is determined by the average energy of each particle due to its motion, which can be calculated using the equation K = 1/2*m*v². This energy is directly proportional to the particle's absolute temperature and can be influenced by changes in mass, velocity, or temperature.

The average kinetic energy of particles in an object refers to the average amount of energy that each individual particle has due to its motion. This energy, denoted as K, can be calculated using the equation K = 1/2*m*V² where m is the particle's mass and V is its velocity. The kinetic energy of a particle is directly proportional to its absolute temperature.

For example, in the context of thermodynamics, an air molecule at room temperature (approximately 293 K) will have an average kinetic energy of (1.38 × 10-23 J/K)(293 K) = 6.07 × 10-21 J. Meanwhile, immediately following the Big Bang, when the universe's temperature was approximately 10³² K, the average thermal energy of a particle would have been 10¹⁹ GeV.

The average kinetic energy of particles in an object can vary based on factors such as changes in mass, velocity, or temperature. For example, in the image provided (Figure 11.4), the higher-temperature region contains particles with higher kinetic energy, while those in the lower-temperature region have lower kinetic energy. Collisions between particles can cause energy to transfer from higher-energy to lower-energy particles, thereby changing the average kinetic energy of the particles in the system.

Metabolism is the answer

Answer:

Friction

Explanation:

Friction is rubbing two objects together. When this happens electrons from one object goes to the other. When one object loses electrons, it will have more protons, so it will be positively charged. When one object gains electrons it becomes negatively charged.

This is what happens when you rub a rubber balloon on your hair, or even on the wall. Because one will be negatively charged and the other positive, the objects then attract each other and they stick together, like what happens when you rub the balloon on your hair, you hair will stick to the balloon, or vice-versa.

20 J

Explanation:

First find the acceleration:

F = ma

20 N = (10 kg) a

a = 2 m/s²

Now find the final velocity:

v = at + v₀

v = (2 m/s²) (1 s) + 0 m/s

v = 2 m/s

Inertia is the physical property that describes an object's resistance to changes in motion, related to its inertial mass.

The measure of resistance to motion by an object is often referred to in Physics as inertia. Inertia is the property of an object that quantifies how much it resists a change in its state of motion. It is directly related to an object's inertial mass, which is a numerical measure of this resistance. When a force is applied to an object, the inertial mass determines how difficult it is to change the object's motion, whether the object is at rest or in motion.

In more detailed terms, rotational inertia (symbolized as I) is the resistance of an object to changes in its angular velocity. In electrical terms, resistance, commonly measured in ohms (Ω), is a measure of the opposition that a piece of wire, for example, offers to the flow of electricity. Both inertia and electrical resistance are foundational concepts in Physics that deal with how an object resists changes imposed upon it, either in terms of motion or electric current.

In summary, concepts such as inertia, inertial mass, and resistance are essential to understanding the motion of objects and the flow of electric current in physical systems. These concepts are also critical for measurements, which include figures like the kilogram for mass or ohms for electrical resistance.

Answer:

E=252J

Explanation:

The total mechanical energy of an object or system is given by:

E mech=K+U

Where K is the kinetic energy of the object and U is the potential energy of the object. The carriage, sitting motionless at the top of the hill, has only potential energy in the form of gravitational potential energy.

Gravitational potential energy is given by:

Ug=mgh

Where m is the mass of the object, g is the gravitational acceleration constant, and h is the height of the object above some specific reference point, in this case the ground 21 m below.

The weight of a stationary object at the surface of the earth is equal to the force of gravity acting on the object.

W=→Fg=mg

We are given that the carriage weighs 12 N, therefore mg=12N.

Ug=12N⋅21m

⇒Ug=252Nm=252J

Hope it helped, God bless you!

The baby carriage at the top of the hill possesses gravitational potential energy. Using the formula for potential energy (PE = m x g x h) and given values for mass, gravity, and height, we find the energy of the carriage is 823.2 Joules.  The carriage has gravitational potential energy.

The energy of the baby carriage at the top of the hill is known as gravitational potential energy, which can be calculated using the formula PE = m x g x h where m is the mass, g is the acceleration due to gravity and h is the height above the ground.

In this case, the mass (m) is 4 kg, the gravitational acceleration (g) is approximately 9.8 m/s², and the height (h) is 21 m. Plugging these values into the formula gives us a potential energy (PE) of PE = 4 kg x 9.8 m/s² x 21 m = 823.2 Joules.
