Which of the following objects is in equilibrium?
Answer:
C) an object that moves at constant velocity.
Explanation:
It is equilibrium because acceleration is just the speed and force at the beginning, while velocity is the overall speed that has remained constant throughout the cycle of the object's movement.

The velocity of a car doubles over a short period of time. Which additional information is sufficient to determine the amount of acceleration during this time period?
Answer:
Time and velocity
Explanation:
The time taken for the velocity to double is very important to find the amount of acceleration the car acquires.
Acceleration is the rate of change of velocity with time.
Acceleration = [tex]\frac{v -u}{t}[/tex]
v is the initial velocity
u is the final velocity
t is the time taken
So, the velocity and time is needed to calculate the value of the acceleration the car undergoes.

La superficie de unas botas suman 400 cm2 y la persona que las usa tiene 45 kg de masa, calcula la presión que ejerce sobre el piso. NOTA: Se debe encontrar la fuerza, para lo cual, se debe obtener el peso utilizando la fórmula de masa por gravedad que es 9.8 m / s2
Answer:
11025 N / m²
Explanation:
Los siguientes datos se obtuvieron de la pregunta:
Área (A) = 400 cm²
Masa (m) = 45 Kg
Aceleración por gravedad (g) = 9,8 m / s²
Presión (P) =?
A continuación, determinaremos la fuerza aplicada. Esto se puede obtener de la siguiente manera:
Masa (m) = 45 Kg
Aceleración por gravedad (g) = 9,8 m / s²
Fuerza (F) =.?
F = m × g
F = 45 × 9,8
F = 441 N
A continuación, convertiremos 400 cm² a m². Esto se puede obtener de la siguiente manera:
1 cm² = 0,0001 m²
Por lo tanto,
400 cm² = 400 cm² × 0,0001 m² / 1 cm²
400 cm² = 0,04 m²
Por tanto, 400 cm² equivalen a 0,04 m².
Finalmente, determinaremos la presión ejercida de la siguiente manera:
Área (A) = 0.04 m².
Fuerza (F) = 441 N
Presión (P) =?
P = F / A
P = 441 / 0,04
P = 11025 N / m²
Por tanto, la presión ejercida es 11025 M / m²

Answer:
What was your sleep situation like during your time in space? Did you get more or fewer hours of sleep than when you were on earth? I would be very interested in learning about their answer because they still have to perform tasks that require energy and obviously they would need to sleep but do they have to strap themselves down on a bed so they don't float away? Is it easy to fall asleep in space or would your body be confused because time is so much different that it doesn't even follow the same time zones as on earth? That is why I find this to be interesting for them to answer.
Did you have any activities to do aside from researching and your tasks that were mandatory? What would they have done in their free time? I can’t imagine simply doing work the whole time, did they get to bring along certain games or time wasters to do while in space? I would just be really curious to find out how they occupied their free time or if they even had free time.
What was the most difficult part about being in space? Was it terrifying or was the work overwhelming? Was it scary thinking about returning to earth or staying in space for too long? There are so many ways to answer this question so I would be very interested in understanding their fears and their reason for being afraid.

Write an equation of a line that passes through the point (-9,2) and is perpendicular to the line y = 3x - 12
Answer:
y = (-1/3)x + 5
Explanation:
the gradient of required equation (m2)
the gradient of given equation (m1) = 3
m1*m2 = -1 ( they are perpendicular)
3*m2 = -1
m2 = -1/3
required equation
y = m2 + c
( 9,2) satisfy the above equation
2 = (-1/3)*9 + c
c = 5
y = (-1/3)x + 5

If a small asteroid named ‘B612’ has a radius of only 20 m and mass of
1 × 104 kg, what is the acceleration due to gravity on its surface?
Acceleration produced in the motion of a body under the effect of gravity is called acceleration due to gravity.
It is a vector quantity and it's SI unit is m/s².
It is usually denoted by the symbol g.
Formula of Acceleration due to Gravity:
[tex] \boxed{ \bf{g = \dfrac{GM}{r^2}}}[/tex]
G → Universal Gravitational Constant [tex] \sf (6.67 \times 10^{-11} \ Nm^2/kg^2) [/tex]
M → Mass of the Asteroid (1 × 10⁴ kg)
R → Radius of the Asteroid (20 m)
By substituting values in the equation, we get:
[tex] \rm \longrightarrow g = \dfrac{6.67 \times {10}^{ - 11} \times 1 \times {10}^{4} }{20^2} \\ \\ \rm \longrightarrow g = \dfrac{6.67 \times {10}^{ - 11 + 4} }{400} \\ \\ \rm \longrightarrow g = 0.016675 \times {10}^{ - 7} \\ \\ \rm \longrightarrow g = 1.6675 \times {10}^{ -9} \: m {s}^{ - 1} [/tex]
[tex] \therefore [/tex] Acceleration due to gravity on the surface of small asteroid named ‘B612’ = [tex] \sf 1.6675 \times 10^{-9} \ m/s [/tex]
Acceleration produced in the motion of a body under the effect of gravity is called acceleration due to gravity. Acceleration due to gravity on the surface of small asteroid named ‘B612’ = 1.776 * 10 9 m/s2.
What is acceleration due to gravity?A free-falling item is one that is falling solely as a result of gravity, as was discovered in the previous section of this course. A free-falling object experiences a downward acceleration of 9.8 m/s. (on Earth).
The acceleration of any object moving only as a result of gravity is referred to as the acceleration of gravity.
In fact, this quantity, known as the acceleration of gravity, is so significant to physics that it has its own distinctive symbol, the letter g. The most precise measurement of the gravitational acceleration is 9.8 m/s.

The mass before a reaction is equal to the mass after a reaction? True or false?
Answer:
[tex]\boxed {\boxed {\sf True}}[/tex]
Explanation:
The Law of Conservation of Mass states that mass cannot be created or destroyed.
So, in a chemical reaction, the mass before a reaction and after cannot be different. In other words, the mass of the products must be equal to the product of the reactants.
So, this is a true statement.

The gas-phase reaction between nitrogen and oxygen was carried out in a device designed to maintain constant pressure. There are two cylinders of equal volume with a reaction arrow between them. The cylinder on the left has two molecules of O 2 and two molecules of N 2. The cylinder on the right has four molecules of N O. A constant pressure is applied to both cylinders Write the balanced chemical equation for the reaction between nitrogen oxygen. Include physical states.
Answer:
2N₂(g) + 2O₂(g) ----> 2NO(g)
Explanation:
Gaseous nitrogen and gaseous oxygen reacts in a molar volume ratio of 1 : 1 to produce nitrogen (ii) oxide.
In the reaction, two molecules of nitrogen gas combines with two molecules of oxygen gas in the cylinder to form two molecules of nitrogen (ii) oxide. The equation of the reaction is given below:
2N₂(g) + 2O₂(g) ----> 2NO(g)
Nitrogen (ii) oxide is formed naturally during lightning bolts. The heat released the lightning flashes causes the nitrogen and oxygen in air to combine to form nitrogen (ii) oxide. The nitrogen (ii) oxide formed however, quickly reacts with more oxygen to form nitrogen(ii) oxide.
Nitrogen (ii) oxide is a colorless, poisonous gas. It is slightly denser than air and almost insoluble in water. it is also neutral to litmus.
The balanced chemical equation for the reaction between nitrogen and oxygen is:
2N₂(g) + 2O₂(g) —> 4NO(g)
The equation between nitrogen and oxygen can be written as follow:
N₂(g) + O₂(g) —> NO(g)
The above equation can be balance as illustrated below:
There are 2 atoms of O on the left side and 1 atom on the right side. It can be balance by writing 2 before NO as shown below:
N₂(g) + O₂(g) —> 2NO(g)
Multiply the equation by 2, we have:
2N₂(g) + 2O₂(g) —> 4NO(g)The equation is balanced!

an average net force of 31.6 N is used to accelerate a 15.0 kg object uniformly from rest to 10.0 m/s leftward. What is the change in momentum?
Answer:
-150 kg m/s
Explanation:
The change of momentum is calculated as ;
Δp= m*Δv where
where
Δp= change in momentum
Δv = vf-vi
m= mass of the object
Change in momentum is also calculated when using the formula;
Δp = F * Δt when F is the net force applied and Δt is the time of action.
In this case;
m= 15 kg
vf= -10 m/s
vi= 0 m/s
Taking rightward direction to be positive, then leftward will be negative.
Applying the formula as;
Δp = m*Δv
Δp = 15 * { -10 -0} = 15*-10 = -150 kg m/s
Your task now is to look up the effects of the temperature on an equilibrium and how the reaction will shift when adding or removing heat. Explain in no less than 4 complete sentences the effect of the temperature and list at least on example.
Answer:
If you increase the temperature, the position of equilibrium will move in such a way as to reduce the temperature again. It will do that by favouring the reaction which absorbs heat. In the equilibrium we've just looked at, that will be the back reaction because the forward reaction is exothermic.
