Answer:

The "distance" is the answer to the question,

Explanation:

Answer:

14.4m/s

Explanation:

To calculate the final velocity (V), we use the formula:

v = u + at

Where; v = final velocity (m/s)

u = initial velocity (m/s)

a = acceleration (m/s²)

t = time (s)

According to the provided information in this question, v = ?, u = 0m/s, a = 1.8m/s², t = 8s

Hence, v = u + at

v = 0 + (1.8 × 8)

v = 0 + 14.4

v = 14.4m/s

Therefore, his final velocity at the end of those 8 seconds is 14.4m/s.

Answer:

1. Which limiting factor(s) in this lab simulation are biotic?

The limiting factors in this lab that are biotic are predators and food.  

2. Which limiting factor(s) in this lab simulation are abiotic?

The limiting factor in this lab that is abiotic is pollution.  

3. Which limiting factor impacted the cricket frog population the most? Use evidence to support your answer.

The limiting factor that impacted the cricket frog population the most is the predators because the population went to 90K and then all the way down to 15K.

4. Which limiting factor impacted the cricket frog population the least? Use evidence to support your answer.

The limiting factor that impacted the cricket frog population the least is pollution because it stayed the same then went down to 35K.

5. Mosquitoes can carry and transmit disease to animals and humans. Explain how the cricket frog plays an important role in limiting the spread of mosquito-borne illnesses like West Nile virus and malaria.

The cricket frogs play an important role in limiting the spread of mosquito borne illnesses because they consume the mosquitos and decrease the population of contaminated mosquitos.  

6. Predict the long-term effects of these limiting factors on the cricket frog population in the pond ecosystem.

Eventually the cricket frog population may die out because of all the negative factors. If there are too many mosquitoes, then the frog population can begin to die out. With pollution, the frogs do not have a safe and clean environment to leave in and can get infected, sick, and can die after a while. Crocodiles need to eat, so they are also bringing down the population.

Answer:

Inertia of an object depends on the mass of the object.

Explanation:

Inertia is the property that is possessed by a matter( anything that has weight and occupies space) that enables it to be at rest or in a state of continuous uniform motion.

The inertial of a body is the resistance that is present in the body, that forces acting on the body have to overcome for the body to move or continue moving.

The inertia of a body depends on the mass of such a body, which is directly proportional. The mass of an object is the measure of inertia,  the bigger the mass of an object the bigger the inertia.

Therefore the Inertia of an object is largely dependent on the mass of such an object.

Answer:

The amount of moisture air can hold is dependent on its temperature and pressure. The warmer the air the greater the quantity of water vapour it can contain. The air temperature is measured with a normal thermometer this is the Dry-Bulb reading. The actual amount of moisture known as the mixing ratio is measured in grams of water per kilogram of dry air. When air at a certain temperature is saturated it cannot hold any more moisture. The relative humidity of the air is the ratio of the actual amount of moisture in the air to the fully saturated amount.

We can use evaporation to measure the amount of moisture in the air. A wet cloth is placed over the bulb of a thermometer and then air is blown over the cloth causing the water to evaporate. Since evaporation takes up heat, the thermometer will cool to a lower temperature than a thermometer with a dry bulb at the same time and place. The depression in Wet-Bulb temperature allows the humidity to be calculated. If the air is fully saturated (100% relative humidity) the water cannot evaporate, so both the wet and dry bulb temperatures are the same. If the dry and wet bulb temperatures are set to the same value the calculator will show the saturation mixing ratio the amount of water in saturated air at that temperature.

If partly saturated air is cooled without changing its pressure or amount of water vapour, a point is reached when it becomes saturated. The moisture will be given up as dew or ice crystals. This temperature is the Dew Point. This is why condensation will form on a bottle of cold beer, as the air in the vicinity of the bottle is cooled below its dew point. Meteorological reports usually quote the temperature and dew point as well as the station pressure. Moisture content and relative humidity can be calculated from these figures.

The Psychrometer is the name of a device containing both a wet and dry bulb thermometer. This can be a fixed device for meteorology or a handheld sling psychrometer that is often used in air conditioning applications.

Explanation:

Answer:

The air around you has weight, and it presses against everything it touches. That pressure is called atmospheric pressure, or air pressure. It is the force exerted on a surface by the air above it as gravity pulls it to Earth.

Atmospheric pressure is commonly measured with a barometer. In a barometer, a column of mercury in a glass tube rises or falls as the weight of the atmosphere changes. Meteorologists describe the atmospheric pressure by how high the mercury rises.

An atmosphere (atm) is a unit of measurement equal to the average air pressure at sea level at a temperature of 15 degrees Celsius (59 degrees Fahrenheit). One atmosphere is 1,013 millibars, or 760 millimeters (29.92 inches) of mercury.

Atmospheric pressure drops as altitude increases. The atmospheric pressure on Denali, Alaska, is about half that of Honolulu, Hawai'i. Honolulu is a city at sea level. Denali, also known as Mount McKinley, is the highest peak in North America.

Answer:

Rahul is wrong.

Explanation:

From Newton's universal law of gravitation, we know that the force of attraction between two falling body masses is directly proportional to product of masses of two bodies and has an inverse proportional relation with the square of the distance between the masses.

If the 2 masses are M1 & M2, while distance between them is d, this can be written as;

F ∝ M1•M2

And F ∝ 1/d²

We also know that the acceleration due to gravity is given as;

g = GM/r²

Where;

M is the mass of earth

r is the radius of earth

From the above 3 formulas, we can deduce that the value of the acceleration due to gravity(g) is independent of the 2 masses of the falling body as it depends on only the mass of the earth and radius of the earth.

This means that the acceleration due to gravity will be the same whether the bricks are doubled or whether it remains single.

Thus, they will fall with same velocity in each case. So Rahul is wrong.

Answer

F (force of gravity) = M (mass of an object) × G (acceleration due to gravity)

Step-by-step explanation:

Force of gravity (F) = Mass (M) × Gravitational acceleration (G)

Explanation:

Answer:

[tex]F_{g} = \frac{m}{d^{2} }[/tex] shows the relationship between gravity and mass.

Explanation:

According to the Newton's law of gravitation, the gravitational force between two bodies is,

       [tex]F_{g} = G.\frac{m_{1}.m_{2} }{d^{2} }[/tex]

here [tex]m_{1} and m_{2}[/tex] are masses, d is distance between them.

It states that gravitational force acting two bodies is directly proportional to the product of masses and inversely proportional to the square of the distance between them.

In above formula ,

If [tex]m_{1} = 1 and[/tex]  [tex]m_{2} = m[/tex]

so [tex]F_{g} = G \frac{m}{d^{2} }[/tex]

Since G is constant ,

    [tex]F_{g}[/tex] ∝[tex]\frac{m}{d^{2} }[/tex]

Hence second option is correctly showing relationship between gravity and mass.

Answer:

Is it a sin to like them all...? haha

Answer:

Schlatt, Nikki, Tubbo, and Wilbur :O

Explanation:

how is this a question lol-

Answer:

The gravitational force between two objects, one of mass M1 and the other of mass M2, is:

F = G*M1*M2/R^2

Where G is a constant:

G = 6.6x10^11 m^3*/(kg*s^2)

And R is the distance between the two objects.

M1 = 5.9742x10^24 kg

M2 = 7.36x10^22 kg

R = 382171 km = 382171000 m

Then the gravitational force is:

F = 6.6x10^-11 m^3*/(kg*s^2)*(5.9742x10^24 kg)*(7.36x10^22 kg)/(382171000 m)^2

F = 1.987x10^20 N

Answer:

The torque is  [tex]\tau = B * m sin(\phi )[/tex]

Explanation:

Generally when current flow through a rectangular loop the magnetic dipole generated we can denote this as  [tex]\vec m[/tex]

Here k is the length of the side of one side of the rectangular loop

Now when this loop is place in a magnetic field, the torque it experience is mathematically represented as

      [tex]\vec \tau = \vec B \ X \ \vec m[/tex]

Here  X stands for cross - product

From the question we are told that the angle between the vector ( [tex]\vec m[/tex])perpendicular to the plane of the coil and magnetic field(B) as [tex]\phi[/tex]

So

=>     [tex]\tau = B * m sin(\phi )[/tex]

Answer:

 E_aprox = 1.003 E_real

Explanation:

In this exercise we are given the expression for the electric field of a dipole in the axis direction of the dipole

         E_real = k 2q d / √(z² + d²)³

I think your equation has some errors.

In this case they indicate that d is the separation of the charges of the dipole

in the case of z »d this equations approximates

        E_aprox = k 2q  d/ z³

calculate the value for the two cases

         E_real = k2q  d / √[ ((23d)² + d²)³]  

         E_real = k2q  d / d³ 12201

         E_real = k2q   1/12201 d²

         E_aprox = k2q   d / (23.00d)³

         E_aprox = k2q   1/12167 d²

    the error between these quantities is

        E_aprox / E_real = 12201 d² / 12167 d²

        E_aprox / E_real = 1.003

        E_aprox = 1.003 E_real

Answer:

[tex]\boxed {\tt t\approx 38.89 \ s}[/tex]

Explanation:

Time can be found by dividing the distance by the speed.

[tex]t=\frac{d}{s}[/tex]

The distance is 350 meters.

The speed is 9 meters per second.

[tex]d= 350 \ m \\s= 9 \ m/s[/tex]

Substitute the values into the formula.

[tex]t=\frac{350 \ m}{9 \ m/s}[/tex]

Divide. Note that the meters or "m" will cancel each other out and the seconds or "s" will move to the numerator.

[tex]t=\frac{350 }{9 \ s}[/tex]

[tex]t=\frac{350 \ s}{9}[/tex]

[tex]t=38.8888889 \ s[/tex]

Round to the nearest hundredth. The 8 in the thousandth place tells us to round the 8 to a 9.

[tex]t \approx38.89 \ s[/tex]

It will take about 38.89 seconds to swim 350 meters at 9 meters per second.
