Explanation:

Electricity is the [tex]\sf{\underline{flow}}[/tex] of electrons, because electrons [tex]\sf{\underline{passes}}[/tex]  from atom to atom.

Answer:

Explanation:

The radius of the smaller bubble, r1 will decrease and that of the bigger bubble, r2 will increase.

The pressure that is present in the smaller bubble usually is greater than the pressure that exists inside that of the bigger bubble. This then makes air to flow from r1 to r2 thereby making the radius of the smaller bubble r1, to decrease while keeping that of the bigger bubble r2 higher.

Increasing the distance between the objects

here's the Answer :

=》Increasing the distance between the objects.

since, gravitational force is inversely proportional to the distance between the objects, so if the distance increases the force will decrease.

[tex]gravitational \: force \: \: \dfrac{1}{ \alpha } \: \: distance[/tex]

Answer:

It is (a) pull because when we are on earth we have gravity and it is pulling us down hope you have a great day!! :)

Answer:  

Exothermic Reaction  

Explanation:  

ENDOTHERMIC REACTION: A chemical reaction is considered endothermic if the energy is absorbed during the reaction. In other words, if the energy is required by the reactants to proceed with the reaction, then the reaction is endothermic.

The value of enthalpy change ΔH is positive in such reactions showing intake of energy.

EXOTHERMIC REACTION: A chemical reaction is considered exothermic if the energy is released during the reaction. In other words, if the energy is produced as a product of the reaction, then the reaction is exothermic.

The value of enthalpy change ΔH is negative in such reactions showing the release of energy.

Since, the value of ΔH = -125 KJ, is negative for the given reaction.

Therefore, it would be considered as Exothermic Reaction.

please mark brainliest

Answer:

1)    v = 2.5 m / s, 2)  v = -0.5 m / s

Explanation:

For this exercise we will use the kinematics relations

1) velocity is defined by

         v = [tex]\frac{dx}{dt}[/tex]dx / dt

this definition serves for the instantaneous and the average velocity if the displacements are linear in time

         v = 20/8

         v = 2.5 m / s

b) for this part we use

          v = [tex]\frac{\Delta x}{\Delta t}[/tex]

         Δx = x_f -x₀

we must place a reference system, where the direction to the right is positive

         x_f = -2 m

         x₀ = +3 m

         Δx = -2 -3

         Δx = -5 m

we calculate

         v = -5 / 10

         v = -0.5 m / s

this value is a scalar

Answer:

Exothermic because energy is a product

Explanation:

Since energy is a product, heat was released, meaning that the reaction is exothermic.

Answer: Newton

Explanation:

Isaac Newton is viewed as one of history's most persuasive researchers. During his lifetime, Newton created the hypothesis of gravity, the laws of movement (which turned into the establishment of material science), another strategy for arithmetic known as analytics, and leap forwards in optics like the reflecting telescope.

Answer:

The answer is B.

Explanation:

It has a central nucleus composed of 29 protons and 35 neutrons, surrounded by an electron cloud containing 29 electrons.

Answer:

86N

Explanation:

The bird is going south and the wind is also blowing south so all the force is acting in the same direction thus it all adds up.

Answer:

On a distance time graph, the distance will always be the dependent variable on the y- axis. Time is the independent variable and will always be placed on the x-axis. The lines on the graphs can tell you many different things.

Explanation:

ANSWER:

the dependant variable is on the y axis and the independent variable is on the x axis.

Answer

Explanation:

As the three resistors are connected in series, the expression to be used for the  

calculation of RT equivalent resistance

is:  

RT = R1 + R2 + R3

We replace the data of the statement in the previous expression and it remains:  

5 10 15 RT + R1 + R2 + R3 + +

We perform the mathematical operations that lead us to the result we are looking for:  

RT - 30Ω

Answer:

its "up, then down, then up"

Explanation:

Answer:

Explanation:

Inertia is the property of a body by virtue of which it opposes any agency that attempts to put it in motion or, if it is moving, to change the magnitude or direction of its velocity.

The more mass, the more inertia. If you increase the mass of the object then you increase the inertia.

Answer:

12 N

Explanation:

Given that a 12 kg object's velocity changes from 5 m/s to 10 m/s in 5 s, what amount of force was applied to increase the speed of the object?

Solution

M = 12 kg

T = 5 s

The formula to use will be

F = ma

Where

Acceleration a = change in velocity/ time

Acceleration a = ( 10 - 5 ) / 5

Acceleration a = 5 / 5

Acceleration a = 1 m/s^2

Substitutes a into the formula above

F = ma

F = 12 × 1

F = 12 N

Therefore, the amount of force applied to increase the speed of the object is 12 N.

Answer:

, pfx = pix + Jx.

Explanation:

The momentum principle tells us that impulse transfers momentum to an object.

If an object has 2 kgm/s of momentum, a 1 kgm/s impulse delivered to the object

increases its momentum to 3 kgm/s. That is, pfx = pix + Jx.

Just as we did with energy, we can represent this “momentum accounting” with a

momentum bar chart. For example, the bar chart of FIGURE 11.6 represents the ball

colliding with a wall in Figure 11.4. Momentum bar charts are a tool for visualizing

an interaction
