Answer: Aplitude

Explanation: Loudness depends on the amplitude,or height, of sound waves. The greater the amplitude, the louder the sound perceived. Amplitude is measured in decibels.

Answer:

Amplitude

Explanation:

The loudness of a sound is determined by the amplitude of the wave. In terms of the pattern of a transverse wave, amplitude refers to how "high" and "low" the waves go from the center line.

Hi there!

a = -9.81 m/s²

When throwing a ball into the air (ignoring air resistance), the acceleration in the vertical direction is ALWAYS constant and equal to the acceleration due to gravity.

In this instance, the acceleration due to gravity is downward, resulting in the object falling. So, we must put a negative sign:

Thus, a = -9.81 m/s².

Answer:

No time interval???

Explanation:

convert from km/h to m/s (speed)

27×1000/3600

27000/3600

=7.5m/s

a= v-u/t

a= 30-7.5/t

a= 22.5/t (m/s²)

Answer:

F = M a    is a vector equation

F has the same sign as A and is in the same direction as the vector a

If a is positive then F must also be positive

If an object has an increasing positive acceleration, then  we can assume that there is some unbalanced increasing force acting on it as the force is the product of the mass of the object and the acceleration.

Newton's Second Law states that The resultant force acting on an object is proportional to the rate of change of momentum.

The acceleration of an item rises proportionately to the force applied to it. So, doubling the force also doubles the acceleration.

Since the force is equal to the product of the item's mass and acceleration, if an object is moving at an increasing positive acceleration, we may infer that there is an imbalanced growing force acting on it.

Hi there!

We can use the derived equation to solve:

[tex]t = \sqrt{\frac{2h}{g}}}[/tex], where:

h = height

g = acceleration due to gravity

Plug in the given values. Remember to CONVERT km to m:

32 km = 32 km * 1000 m / 1 km = 32,000 m

t = √(2(32000)/3.4) ≈ 137.199 sec

Part 2:

Use the derived equation:

vf = √2gh

vf = √(32000)(3.4) = 329.848 m/s

Answer:

Neutral

Explanation:

A neutral atom has an equal number of protons and electrons so that the positive and negative charges exactly balance. Since it is the electrons that determine how one atom interacts with another, in the end it is the number of protons in the nucleus that determines the chemical properties of an atom.

Answer:

This reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen. Add 2 molecules of hydrogen peroxide and 2 molecules of water. Since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

Explanation:

The largest input of solar energy strikes the Earth at the equator.

Answer:

When a ball is thrown up in the air, the ball's velocity is initially upward. Since gravity pulls the object toward the earth with a constant acceleration g, the magnitude of velocity decreases as the ball approaches maximum height.

Answer:

In order to determine if the cathode ray consisted of charged particles, Thomson used magnets and charged plates to deflect the cathode ray. He observed that cathode rays were deflected by a magnetic field in the same manner as a wire carrying an electric current, which was known to be negatively charged.

Explanation:

According to the right-hand rule, the magnetic field causes the electrons to be refracted. Turn on the power strip to learn about the Cathode Ray (electron beam) Deflection by an Electric Field.

Magnetic forces can be seen in a magnetic field, an electric current, a changing electric field, or a vector field around a magnet. Magnetic compass needles and other permanent magnets align in the direction of magnetic fields like the one found on Earth. Electrically charged particles are forced to move in a circular or helical pattern by magnetic fields. The operation of electric motors is caused by this force, which is applied to electric currents in wires in a magnetic field.

The Lorentz Force, which is explained by the left-hand rule, has an impact on what happens inside the tube. In accordance with this law, an electron or other charged particle travelling in a magnetic field will be deflected by the field at a right angle to both the field's direction and the direction of the particle.

Answer:

Because it filters

Explanation:

it filters out the urine, and changes it into nutrients I'm pretty sure

Explanation:

theta = 90-53(we are getting horizontal angle)

=37

force(F)=23N

vertically =Fsin(theta)=23sin(37)=13.84N

horizontally=Fcos(theta)= 23cos(37)=18.37N

If a cart was pushed in a ramp exerting 23 Newtons upward creating an angle of 53° north of the west, then the horizontal component of the force would be 13.84 Newtons, and the vertical component of the force would be 18.36 Newtons.

Newton's Second Law states that The resultant force acting on an object is proportional to the rate of change of momentum.

As given in the problem if a cart was pushed in a ramp exerting 23 Newtons upward creating an angle of 53° north of the west,

The horizontal component of the force = 23 × cos 53° Newtons

                                                                 =13.84 Newtons

The vertical component of the force =  23 × cos 53° Newtons

                                                           =18.36 Newtons

Thus, the horizontal component of the force would be 13.84 Newtons, and the vertical component of the force would be 18.36 Newtons.

The characteristics of the magnetism allow to find the results for the questions related to the division of the magnetic bar are:

The magnetic field is understood today as the effect of the movement of electric charges, in this sense there is no magnetic monopole since the orbital or spin movement of the charges is continuous.

The dipole or magnetic moment is caused by the movement of the electrons around the nucleus, in some cases the movements are in the opposite direction and can be annulled and the electrons grinding on themselves called spin.

A magnet is a material where there is a permanent magnetic field formed by the sum of all the microscopic contributions, this sum gives a dipole or total magnetic moment different from zero.

They indicate that a bar-shaped magnet is cut into four parts, each part forms a smaller magnet, that is, each part is a magnetic dipole.

In conclusion, using the characteristics of magnetism we can find the results for the questions about the division of the magnetic bar are:
