if your mass is 72kg your textbooks in Madison has 3.7 kg and you and your textbook are separated by a distance of 0.33 M what is the gravitational force between you and your textbook

Answer:

Option A. 500

Explanation:

From the question given, we obtained the following:

Numbers of home with pet dogs = 250

Percentage with pet dogs = 50%

Total number of homes =.?

Thus, we can obtain the total number of homes represented by the chart as follow:

Let T be the total number of Homes.

Number of homes with dog = percentage of homes with dog × total number

Numbers of home with pet dogs = 250

Percentage with pet dogs = 50%

Total number of homes = T

250 = 50% × T

Divide both side by 50%

T = 250 ÷ 50%

T = 250 ÷ 50/100

T = 250 × 100/50

T = 250 × 2

T = 500

Therefore, the total number of homes represented by the chart is 500.

Answer:

3149.181 N

Explanation:

the force exerted by the atmosphere can be calculated as

F = PA

Where P is the atmospheric pressure and A is the area of the sheet of paper.

The atmospheric pressure is P = 101325 Pa

And the area is equal to

A = Length x Width

A = 0.148 m x 0.210 m

A = 0.03108 m²

Because 14.8 cm = 0.148 m and 21.0 cm = 0.210 m

Now, we can calculate the force as

F = (101325 Pa)(0.03108 m²)

F = 3149.181 N

So, the force exerted is 3149.181 N

The wavelength of a cell-phone signal with a frequency of 847.2 MHz is approximately 3.54 x 10^-1 meters or 0.354 meters.

1. To find the frequency of light with a wavelength of 668 nm, you can use the formula:

Frequency (f) = Speed of light (c) / Wavelength (λ)

The speed of light (c) is approximately 3.0 x 10^8 meters per second (m/s), and the wavelength (λ) is given in nanometers (nm). First, convert the wavelength to meters:

668 nm = 668 x 10^-9 meters

Now, apply the formula:

f = (3.0 x 10^8 m/s) / (668 x 10^-9 m)
f ≈ 4.49 x 10^14 Hz

So, the frequency of light with a wavelength of 668 nm is approximately 4.49 x 10^14 Hz.

2. To find the wavelength of a cell phone signal with a frequency of 847.2 MHz, you can use the same formula. First, convert the frequency to Hz:

847.2 MHz = 847.2 x 10^6 Hz

Now, rearrange the formula to find the wavelength (λ):

Wavelength (λ) = Speed of light (c) / Frequency (f)

λ = (3.0 x 10^8 m/s) / (847.2 x 10^6 Hz)
λ ≈ 3.54 x 10^-1 meters

The direction of the magnetic field in a magnet is determined by using use a compass. Place the compass near the magnet and the needle will point in the direction of the magnetic field.

There are two ways to determine the direction of the magnetic field in a magnet. The magnetic field of a magnet can be determined by two methods:

The compass method: The north end of a compass always points in the direction of the magnetic field line, and the south end points in the opposite direction. Therefore, the magnetic field direction of a magnet may be determined by positioning a compass near it.

The right-hand rule method: Consider a current-carrying wire. If the right-hand thumb points in the direction of the current, the magnetic field lines follow the direction of the curled fingers. This is true only for a straight wire, and if the current is changing or there is a gap in the wire, the magnetic field lines are different.

Therefore, if you have a magnet and you know the direction of the current or movement, you may use the right-hand rule to determine the magnetic field direction.

Identification of compounds can benefit from density. It is also a useful feature since it connects (or acts as a conversion factor between) a substance's mass and volume. Volume and mass are extended (or extrinsic) qualities of matter that are quantity dependent.

The force of an air mass acting on the earth's surface is known as atmospheric pressure. Remember that wind currents are created when the densities of two separate air masses differ.

Our wind currents are driven by the atmospheric pressure density, and denser air exerts a higher pressure than less dense air. Compared to the cold and dry air, the warm and humid air is less dense. The less dense air will then float on top of the thicker air in certain regions.

Therefore, Warm air masses rise while cold air masses descend because they are less dense.

It is FALSE that the proportionality dependence of the current (i) through any conductor to the voltage (v) across it and its resistance (r) is true for all conductors regardless of temperature.

When the conductors have a higher temperature, the molecules in the conductor will be more crowded and the result is the resistance of the conductor will rise. Hence, the current flowing through the conductor will decrease in the same voltage.

In the lower temperature, the resistance of the conductor will decrease and lead to more current flowing through the conductor in the same voltage.

Thus, the conductor temperature has an effect on its resistance.

The correct answer is frequency.

The number of cycles or vibrations per unit of time is known as the frequency in a system undergoing simple harmonic motion. Frequency is a fundamental characteristic of oscillatory motion and is measured in hertz (Hz).In simple harmonic motion, an object oscillates back and forth around an equilibrium position, following a sinusoidal pattern. The frequency of the motion determines how quickly the object completes one full cycle or vibration.The relationship between frequency (f), period (T), and angular frequency (ω) in simple harmonic motion is as follows:

f = 1/T

ω = 2πf

Where T is the period, representing the time taken to complete one full cycle, and ω is the angular frequency, representing the rate of change of angle with respect to time.The frequency of a system in simple harmonic motion describes the number of cycles or vibrations completed by the object per unit of time. It is an important parameter that characterizes the oscillatory behavior of the system.

Answer:

Explanation:

Answer:

brooo it is rotation .............

The angular momentum of a particle rotating with a central force is constant due to the conservation of angular momentum. This principle states that the total angular momentum of a system remains constant if no external torque acts on it.

When a particle is rotating with a central force, such as in the case of an object moving in a circular orbit under the influence of gravitational force, the net external torque acting on the particle is zero. This means that there are no external forces causing the object to rotate faster or slower.

The angular momentum of a rotating particle is given by the product of its moment of inertia (a measure of its resistance to rotation) and its angular velocity. Since the net external torque acting on the particle is zero, the angular momentum remains constant.

In simple terms, this means that as the particle moves in its orbit, its angular velocity may change, but the product of its moment of inertia and angular velocity remains the same. For example, if a planet moves closer to the sun, its angular velocity increases to compensate for the decrease in its distance from the sun.

The initial observation of a purple-colored solution formed when a potassium permanganate particle was added to water is due to the dissolution of the compound, which releases colored MnO4- ions into the solution.

(a)

(i) The observation made after two hours of leaving the potassium permanganate particle in water would be the formation of a purple-colored solution.

(ii) The above observation can be explained by the dissolution of the potassium permanganate particle in water. Potassium permanganate is a water-soluble compound.

When it is added to water, the particles of potassium permanganate dissociate into potassium (K+) and permanganate (MnO4-) ions. The purple color of the solution is due to the presence of the MnO4- ions, which are intensely colored.

(b)

(i) The observation made when water is continually added to the solution formed in (a) until in excess would be the disappearance of the purple color and the formation of a colorless solution.

(ii) This observation suggests that the particulate nature of matter is such that the excess water added to the solution causes further dilution of the solution. As more water is added, the concentration of the potassium permanganate ions decreases.

Eventually, when enough water is added, the concentration of the ions becomes extremely low, resulting in a colorless solution. This indicates that the color of the solution was dependent on the concentration of the colored ions.

In summary, the initial observation of a purple-colored solution formed when a potassium permanganate particle was added to water is due to the dissolution of the compound, which releases colored MnO4- ions into the solution. The subsequent observation of a colorless solution upon adding excess water suggests that the concentration of the colored ions has decreased to a point where they are no longer visible to the eye.

Answer:

Option C.   10 m/s²

Explanation:

First we need to find the mass of the object.

We can use Newton's second law to evaluate the mass of the object.

Newton's second law says that the net force of is equal to the mass times it acceleration.

\(F_{net} =ma\)

Lets solve for \(m\).

Divide each side by \(a\).

\(m=\frac{F_{net} }{a}\)

We are given

\(F_{net} =45\\a=5\)

Lets evaluate \(m\).

\(m=\frac{45}{5}\)

\(m=9\)

Now we can find the object's acceleration if the force doubles.

\(F_{net} =ma\)

Lets solve for \(a\).

Divide each side by \(m\).

\(a=\frac{F_{net} }{m}\)

Doubling the force of 45 N leaves us with a force of 90 N.

\(a=\frac{90}{9}\)

\(a=10\)

We can see that the object's acceleration is directly proportional to the net force and inversely proportional to the object's mass.

A force of 6 N was applied to a regulation FIFA soccer ball and it has the 0.4 kg of mass.

The formula that can be used to solve this problem is Force = mass x acceleration (F=ma).

By rearranging the formula to solve for mass, we get m = F/a.

Using the values given in the question, we have:

F = 6 N (the applied force) and a = 15 m/s² (the acceleration of the ball).

Therefore, m = F/a = 6/15 = 0.4 kg.

Thus, the mass of the soccer ball is 0.4 kg.

The soccer ball is an example of an object that is subject to air resistance when it moves. Due to the air resistance, the acceleration of the ball will decrease as it moves further away from the kicker.

Moreover, the ball will eventually reach its terminal velocity when the force of air resistance equals the force applied by the kicker.
