which force produces acceleration in falling bodies?​

Answer:

d

Explanation:

Answer:

9.8 m/s/s

Explanation:

As such, all objects free fall at the same rate regardless of their mass. Because the 9.8 N/kg gravitational field at Earth's surface causes a 9.8 m/s/s acceleration of any object placed there, we often call this ratio the acceleration of gravity

Answer:

1) Lithospheric plates move in the asthenosphere due to rising and sinking of materials is 1.

2) The decomposition of radioactive elements causes heat in the interior part of the Earth

3) Heat slowly rises to the mantle and creates convection current.

4). Heat moves to the core

5) The process repeats as cycle.

Explanation:

Mantle convection is the gradual slow creeping of movement of the Earth's mantle which is as a result of convection current which transfer heat from the interior to the surface of the Earth .

The process of mantle convection start with

1. Lithospheric plates move in the asthenosphere due to rising and sinking of materials is and thus form the two component of the mantle.

2) The decomposition of radioactive elements causes heat in the interior part of the Earth. This is as a result of accretion which is associated to sea flooding

3) Heat slowly rises to the mantle and creates convection current.

4). Heat moves to the core, cools down by conduction and convection of heat.

5) The process repeats as cycle.

The proper and correct arrangement of events in the mantle convection process are:

1. The decomposition of radioactive elements causes heat in the interior part of  the Earth.

2. Heat moves to the core

3. Heat slowly rises to the mantle and creates convection current.

4. Lithospheric plates move in the asthenosphere due to rising and sinking of  materials.

5. The process repeats as a cycle.

Convection is considered to be one of the most efficient ways through which heat is transported from the interior of planet Earth to the surface.

Mantle convection can be defined as the very slow transfer of heat due to the movement of Earth's solid silicate material within the mantle.

Basically, the slow creeping of the mantle causes a transfer of heat from the white-hot core to the brittle lithosphere during mantle convection.

Furthermore, the heating of the mantle takes place from below (the core) and it rises upward in hotter regions while it sinks down in colder regions.

The proper and correct arrangement of events in the mantle convection process are:

1. Heat is caused in the interior part of  the Earth due to the decomposition or decay of radioactive elements.

2. Heat moves to the core.

3. Heat slowly rises from the Earth's core to the mantle and creates convection current in the asthenosphere, which is the plastic layer of the mantle.

4. Lithospheric plates move in the asthenosphere due to rising and sinking of  materials.

5. The process is then repeated as a cycle.

Hey!

Your answer is that the ATOMIC MASS of Helium is 4 u ROUNDED to 2 decimal places!

Explanation:

The precise amount is 4.002602 u.

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:

 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

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:

The resultant of the vector is 6.63 km

Explanation:

Given;

vector A = 2.3 km 45°

vector B = 4.8 km 90°

The vectors in the x - direction is given by;

Aₓ = 2.3 km Cos 45° = 1.6263 km

Bₓ = 4.8 km Cos 90° = 0

The sum of the vectors in x -direction is given by;

∑X =  1.6263 km + 0 = 1.6263 km

The vectors in the y - direction is given by;

Ay = 2.3 km Sin 45 = 1.6263 km

By = 4.8 km Sin 90° = 4.8 km

The sum of the vectors in y -direction is given by;

∑Y =  1.6263 km + 4.8 km = 6.4263 km

The resultant vector is given by;

R = √(X² + Y²)

R = √[(1.6263)² + (6.4263)²]

R = 6.63 km

Therefore, the resultant of the vector is 6.63 km

The resultant displacement of the two vectors A and B is 6.63 Km and this can be determined by using the given data.

Given :

The two vectors: A = 2.3 km at 45 degrees B = 4.8 km at 90 degrees.

In order to determine the resultant displacement, first, determine the vector in x-direction:

[tex]\rm A_x=2.3cos45=1.6263 \;Km[/tex]

[tex]\rm B_x=4.8cos90=0 \;Km[/tex]

Now, the sum of the vectors is given by:

[tex]\rm \sum X=1.6263+0=1.6263\;Km[/tex]

In order to determine the resultant displacement, first, determine the vector in y-direction:

[tex]\rm A_y=2.3sin45=1.6263 \;Km[/tex]

[tex]\rm B_y=4.8sin90=4.8 \;Km[/tex]

Now, the sum of the vectors is given by:

[tex]\rm \sum Y = 1.6263+4.8=6.4263[/tex]

Now, the resultant vector is given by:

[tex]\rm R = \sqrt{X^2+Y^2}[/tex]

[tex]\rm R=\sqrt{(1.6263)^2+(6.4263)^2}[/tex]

R = 6.63 Km

The resultant displacement of the two vectors A and B is 6.63 Km.

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.

Three (3).

Explanation:

The octet rule is a rule in chemistry that states that, chemical elements would either gain or loss electrons in their outermost shell in order to attain a stable electronic configuration i.e having eight (8) valence electrons in their outermost shell such as chemical elements found in group 8 (2-8-8) known as noble gas.

A phosphorus atom needs to gain three (3) electrons to achieve a full octet because the atomic number of phosphorus is 15 and as such it has the electronic configuration of 2-8-5 and needs three electron in order to become a stable element.
