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.

Answer:
limbic system
Explanation:
The "limbic system" is situated under the cerebrum. It is responsible for the person's emotions and memories. Its primary structures include: hippocampus, amygdala, thalamus and hypothalamus.
The "hippocampus" is responsible for obtaining new memories. It is also associated with mental functions like "learning."
The "amygdala" is responsible for emotional memories.
The "thalamus" and "hypothalamus" are responsible for reactions towards the emotions.

It is determined that a certain light wave has a wavelength of 3.012 ×10−12 m. The light travels at 2.99 ×108 m/s. What is the frequency of the light wave? (Round your answer to three significant figures.)
Answer:
Explanation:
velocity=frequency*wavelength
velocity = 2.99*10^8 m/s
frequency = ?
wavelength = 3.012*10^-12
2.99*10^8m/s = (f)(3.012*10^-12)
f=9.58*10^19 Hertz

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!

Answer:
what are the options??? to choose the answer from?
Explanation:
Answer:
so its 0.098*C
Explanation:
Let m gram be the mass of water.
Then potential energy of water is:
P.E.=mgh
=m×980×8400
Since potential energy is converted to kinetic energy
P.E.=K.E.
K.E.=m×980×8400
Half of kinetic energy is converted into heat.
Then heat energy:

A limousine driver notices a stop sign while traveling 55 km/h. What
is the acceleration (in m/s) of the limousine if it comes to a complete
stop in 4.3 52
Interpret the sign of the acceleration - what does it mean?
Answer:
a= -12.64 m/s²
The negative sign means deceleration, which shows that the limousine was slowing down to stop.
Explanation:
The formula for acceleration is :
a= change in velocity / time
[tex]a=v_f-v_i/t\\[/tex]
where;
[tex]v_f=0km/h\\\\v_i=55km/h\\\\t=4.352s[/tex]
a= 0-55 /4.352 = -55/4.352 = -12.64 m/s²
The negative sign means deceleration, which shows that the limousine was slowing down to stop.

Answer:
imma take a guess
Explanation:
- For every force exerted on an object, that object exerts the equal and opposite amount of force back.
or like
- The force exerted is an action, and there will always be a force back, the reaction, in an equal and opposite amount.
1. An object accelerates 5.0 m/s when a force of 20.0 newtons is applied to it.
What is the mass of the object?
2. An object accelerates 2.0 m/s when a force of 12.0 newtons is applied to it.
What is the mass of the object?
3.An object accelerates 16.3 m/s when a force of 4.6 newtons is applied to it.
What is the mass of the object?
Answer:
1. mass = 4
2. mass = 6
3. mass = 0.28
Explanation:
All these questions require the equation:
F=ma
Where F is force, m is mass and a is accleration. If we do some algebra, we can modify this equation to find mass by dividing both sides by a.
[tex]F=ma --> \frac{F}{a} =\frac{ma}{a} --> \frac{F}{a} = m[/tex]
The a on the left side cancels out and leaves us with [tex]\frac{F}{a}=m[/tex]. Now we can plug in the numbers given to find the mass.
1.[tex]\frac{F}{a} =m-->\frac{20.0}{5.0}=m-->m=4[/tex]
2.[tex]\frac{F}{a} =m -->\frac{12.0}{2.0} =m -->m=6[/tex]
3.[tex]\frac{F}{a}=m--> \frac{4.6}{16.3}=m--> m=0.28[/tex]
So the answers are m=4, m=6, and m=0.28.

How much tension must a rope withstand if it is used to accelerate a 960 kg car horizontally along a frictionless track at 1.20 m/s²?
Answer:
The tension of the rope is 1152 N
Explanation:
Force
Newton's second law states that the acceleration of an object is directly proportional to the net force and inversely related to its mass.
The law can be written as:
F = m.a
The rope must apply a force F to accelerate the car of m=960 Kg at [tex]a=1.2~ m/s^2[/tex]. Given the track is frictionless, all the force applied produces acceleration, thus:
[tex]F = 960~Kg\cdot 1.2~ m/s^2[/tex]
F = 1152 N
The tension of the rope is 1152 N
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.
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.

Calculate the net acceleration acting on a 40 kg box being pushed across a horizontal floor. There is a 400 N normal force, a 195 N applied force, and a 55 N force of friction resisting any sliding motion. Assume g = 10 m/s ^ 2
Answer:
Net acceleration = 3.5m/s²
Explanation:
Given the following data;
Mass, m = 40kg
Normal force, Fn = 400N
Applied force, Fapp = 195N
Force of friction, Ff = 55N
Mathematically, the net force is given by the formula;
[tex] F_{net} = F_{app} - F_{f}[/tex]
Substituting into the equation, we have;
[tex] F_{net} = 195 - 55 [/tex]
[tex] F_{net} = 140 [/tex]
To find the acceleration;
[tex] F_{net} = ma[/tex]
Making acceleration "a" the subject of formula;
[tex]a = \frac {F_{net}}{m} [/tex]
[tex]a = \frac {140}{40} [/tex]
Net acceleration, a = 3.5m/s²
Vinegar contains 5.00% acetic acid (by mass) and its density is 1.02g / mL
What is the mass of acetic acid, in measured grams, in 185 mL of vinegar?
The mass of acetic acid would be 9.435 grams, in 185 mL of vinegar if Vinegar contains 5.00% acetic acid (by mass) and its density is 1.02g / mL
What is density?It can be defined as the mass of any object or body per unit volume of the particular object or body. Generally, it is expressed as in gram per cm³ or kilogram per meter³.
Generally, the density of any substance is expressed by the greek symbol ρ. The density is the reciprocal of the specific volume of any substance.
.
By using the above formula for density
ρ = mass / volume
As given in the problem Vinegar contains 5.00% acetic acid (by mass) and its density is 1.02g / mL
The total mass of the vinegar
mass= ρ×volume
=1.02×185
=188.7
As given Vinegar contains 5.00% acetic acid (by mass)
the mass of acetic acid = 5×188.7/100
=9.435 gram
Thus, the mass of acetic acid comes out to be 9.435 grams
