Calculate the force of gravity on a 1–kilogram box located at a point 1.3 × 10^7 meters from the center of Earth. (The value of G is 6.673 × 10^-11 newton meter^2/kilogram^2. The mass of Earth is 5.98 × 10^24 kilograms.)

Answer:

q = 0.384 C

Explanation:

The total charge present at the head can be easily found out by multiplying the charge on a single electron with the total number of electrons present on the head:

\(q = ne\)

where,

q = total charge on head = ?

n = total no. of electrons on the head = 2.4 x 10¹⁸

e = charge on 1 electron = 1.6 x 10⁻¹⁹ C

Therefore,

\(q = (2.4\ x\ 10^{18})(1.6\ x\ 10^{-19}\ C)\)

q = 0.384 C

283.33Hz is the next frequency that will be canceled out upon reflection with this distance between rows.

The number of waves that pass through a fixed location in a specific amount of time is known as frequency. As a result, if a wave travels for 1/2 second, the frequency is 2 per second. 100 times per hour is the frequency if it takes 1/100 of an hour.

Given,

L = 1.5

n = 2

Vs = 340

By using following formula calculate λ:

L = (n+1/2)λ/2

1.5 = (2+1/2)λ/2

1.5 = 5λ/4

λ = 1.5×4/5

λ = 1.2

By using following formula calculate frequency:

Vs = fλ

f = 340/1.2

f = 283.33Hz.

Answer:

D

Explanation:

Now we know that Force is the rate of change of momentum meaning

F= mv/t

But

mv/t = Ke

v/t = ke/m

a= ke/m

Where a is acceleration

K is constant of proportionality of tension on a spring

e is the extension substended by a string.

From the formula of acceleration we can see that as mass decreases acceleration increases so we can see that m = 1

We would have a maximum value of acceleration.

Explanation:

The reaction shown is an endothermic reaction. In such reaction, they require an input of energy.

If a flexible air-filled container at 100 feet of sea water has a volume of 10 cu ft,  if it were transported to the surface it would be 10cu.

Volume is a three-dimensional measurement that is used to determine the capacity of a solid shape. It means that the amount of space a closed form can occupy in three dimensions depends on its volume.

For instance, a cup's capacity is stated to be 10 ml if it can hold 10 ml of water in its brim. The quantity of space occupied by a three-dimensional object can also be used to describe volume.

A three-dimensional object's volume is the area it takes up, and it is expressed in cubic units. Cm3 and in3 are two examples of cubic units. The amount of matter in an item can be determined by its mass, on the other hand. The weight of an object is a common way to determine mass.

The true statements about exomoons are:

A. Exomoons are likely to exist

D. Exomoons have been used as locations within science fiction stories

C. Exomoons must be only made of ice

A. Exomoons are likely to exist: It is believed that exomoons could exist in planetary systems beyond our own. While the detection and confirmation of exomoons remains a challenge, their existence is considered plausible based on the understanding of moon formation and the prevalence of exoplanets.

D. Exomoons have been used as locations within science fiction stories: Exomoons, being a fascinating concept, have captured the imagination of science fiction writers. They have been depicted in various stories and movies as intriguing and potentially habitable worlds.

E. Exomoons are moons that orbit exoplanets: An exomoon refers to a moon that orbits an exoplanet, which is a planet outside our solar system. Just like moons in our own solar system, exomoons are expected to orbit exoplanets, providing additional complexity and dynamics to the planetary systems.

C. Exomoons must be only made of ice: This statement is not true. Exomoons can be composed of various materials depending on their formation and composition. While some exomoons could have icy surfaces or subsurface oceans, others may be rocky or have diverse compositions.

It is important to note that our understanding of exomoons is still limited, and further research and observations are required to confirm their existence and study their characteristics.

Answer:

Explanation:

To determine if the shooter could have come from the penthouse, we need to calculate the angle of elevation from the penthouse to the tree. We can use trigonometry to do this.

We know that the height of the penthouse is 85 feet, and the distance from the penthouse to the tree is 60 feet. We can use the tangent function to calculate the angle of elevation:

tan(angle of elevation) = opposite / adjacent

opposite = height of penthouse = 85 feet

adjacent = distance from penthouse to tree = 60 feet

tan(angle of elevation) = 85 / 60

angle of elevation = arctan(85/60)

Now we have the angle of elevation, we can determine if the shooter could have come from the penthouse. If the angle of elevation is greater than 90 degrees, the shooter would have had to shoot at an impossible angle, and the shots could not have come from the penthouse.

In this case, the angle of elevation is approximately 62.9 degrees, which is less than 90 degrees. So the shots could have come from the penthouse.

It's important to note that this is a simplified calculation based on the data provided, and it is not a conclusive evidence. A detailed investigation is required to gather all the facts and evidence before determining the shooter's location.

Doppler's effect:

The Doppler effect states that the frequency of sound increases as it source approaches you and it decreases as the source turns away from you.

When the ambulance drives past you, the pitch of the siren is lower. This is due to the fact that the frequency of the wavelength decreases.

A higher pitch means frequency increases and a lower pitch means frequency decreases.

65.3 kPa is  the new pressure of the helium.

V1=  4800 m3

V2= 7200 m3.

P1= 98 kPa.

P2=?

P1V1=P2V2

P2=P1V1/V2

P2= 98×4800÷7200

P2=65.3 kPa.

The definition of pressure is force/area. For instance, the weight of the snow divided by the area of the roof would represent the pressure from snow on a roof. Gases are often where pressure in chemistry originates from. Vacuum is the term for the lack of pressure. Since "nature abhors a vacuum," humans have believed that vacuums are both impossible and unnatural for hundreds of years. This isn't really the case.

The amount of pressure units is insane! The torr or mmHg is a common unit. Simply put, this refers to the height of a mercury column. The atmospheric pressure is about 760 torr, or mmHg. You may also see mmH2O, which employs the same notion, but in this instance the atmospheric pressure is around 10.3 mH2O since water is less dense than mercury.

Explanation:

En este ejercicio se pide calcular la aceleracion del cuerpo, usemos las ecuaciones de cinematica en una dimensión.

          v= v₀ + a t

como el corredor parte del reposo si velocidad inicial es cero

           v =  at

           a = v/t

          a = 12 /4,0

          a =  3,0 m/s²

The final temperature when 50 ml of water at 80°C is added to 25 ml of water at 25°C is approximately 61.67°C.

To calculate the final temperature, we can use the principle of energy conservation, which states that the total heat lost by one substance is equal to the total heat gained by another substance in a closed system.

First, we can calculate the heat lost by the water at 80°C using the formula:

Q₁ = m₁ * c₁ * ΔT₁

where Q₁ is the heat lost, m₁ is the mass of the water at 80°C, c₁ is the specific heat capacity of water, and ΔT₁ is the change in temperature. Since we have 50 ml of water, we can assume its mass to be 50 grams (as the density of water is approximately 1 g/ml). The specific heat capacity of water is 4.18 J/g°C. Thus:

Q₁ = 50 g * 4.18 J/g°C * (80°C - T)

where T is the final temperature.

Similarly, we can calculate the heat gained by the water at 25°C:

Q₂ = m₂ * c₂ * ΔT₂

where Q₂ is the heat gained, m₂ is the mass of the water at 25°C (25 ml ≈ 25 g), c₂ is the specific heat capacity of water, and ΔT₂ is the change in temperature (T - 25°C).

Since energy is conserved, we can set Q₁ equal to Q₂:

50 g * 4.18 J/g°C * (80°C - T) = 25 g * 4.18 J/g°C * (T - 25°C)

Simplifying the equation, we can solve for T:

50 * (80 - T) = 25 * (T - 25)

4000 - 50T = 25T - 625

75T = 4625

T = 4625 / 75

T ≈ 61.67°C
