What concept does the image above show?
What is inertia and how can you increase an object's inertia?
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.

Three resistors of resistances, R1=10Ω, R2=5Ω, R3=20Ω are connected in a circuit in such way that same amount of current flows through them. Draw a circuit diagram showing the correct connections of the three resistors, a cell of 2.5V, an ammeter and a voltmeter across R3. Calculate the potential difference across R3.
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

If 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?
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.
Would the following reaction be endothermic or exothermic? Why?
CH4 + 02 --> CO2 + H2O + Energy
A. Exothermic because energy is a reactant
B. Endothermic because energy is a reactant
C. Endothermic because energy is a product
D. Exothermic because energy is a product
Answer:
Exothermic because energy is a product
Explanation:
Since energy is a product, heat was released, meaning that the reaction is exothermic.
Consider two soap bubbles having radii r1 and r2 (r1 < r2) connected via a valve. What happens if we open the valve?
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.
Who do you think had the most influence on modern science: Descartes or Newton? And why? i'll give brainliest
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.
What is the kinetic energy of a 78kg object moving at a velocity of 2.5m/s
Answer:
[tex]\boxed {\boxed {\sf 243.75 \ J }}[/tex]
Explanation:
Kinetic energy is energy an object has due to motion. The formula is:
[tex]KE=\frac {1}{2}mv^2[/tex]
The mass of the object is 78 kilograms and the velocity is 2.5 meters per second.
[tex]m= 78 \ kg \\v= 2.5 \ m/s[/tex]
Substitute the values into the formula.
[tex]KE= \frac {1}{2} (78 \ kg)*(2.5 \ m/s)^2[/tex]
Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction. Solve the exponent first.
(2.5 m/s)²= 2.5 m/s * 2.5 m/s = 6.25 m²/s²[tex]KE= \frac {1}{2}(78 \ kg)*6.25 \ m^2/s^2[/tex]
Multiply all three numbers together.
[tex]KE=39 \ kg * 6.25 \ m^2/s^2\\[/tex]
[tex]KE=243.75 \ kg*m^2/s^2[/tex]
1 kilogram meter squared per second squared is equal to 1 Joule. So, our answer of 243.75 kg *m²/s² is equal to 243.75 Joules.
[tex]KE=243.75 \ J[/tex]
The object has 243.75 Joules of kinetic energy.
On a distance-time graph, which is your independent and dependent variable?
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.

If a chemical reaction has a AH value of -125 kJ, it would be considered what?
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.

A bird flies South for the winter at a constant force of 51 N. Suddenly a wind with a force of 35 N blows due South. What is the net force of the bird?
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.
1. Un móvil se desplaza 20m e invierte 8 segundos en hacerlo. ¿Cuál es su velocidad instantánea? 2. Un móvil parte a 3 metros después del origen y se detiene a 2 metros antes de este. Si demora 10 segundos en su desplazamiento. Calcular su rapidez.
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

Calculate the total momentum of the three-sphere system if the three spheres are swung at −1.0 msto the left.
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
