The resulting acceleration is 6m/s^2 , when a net force of 18 N is applied to a 3.0 kg mass.
Fnet = 18N
m= 3kg
Fnet = ma
18 = 3a
6m/s^2 = a
What is acceleration ?"Acceleration is the rate of change of the velocity of an object with respect to time. Accelerations are vector quantities. The orientation of an object's acceleration is given by the orientation of the net force acting on that object."
What is force ?"A force is an influence that can change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity."

At night, within how many feet of approaching a vehicle from the rear must you dim your high beam headlights
Answer: 500 ft
Explanation:
High beam headlights help one to see better at night as the range of vision is greatly expanded. They can however, blind drivers coming on the opposite lane.
It is therefore prudent to ensure that when using high beam headlights, you dim them when a car is coming towards you. The appropriate distance to do so is a minimum of 500 ft from the car.

Answer:
the answers should be B and D
Answer:
Q. 1 is transform
Q. 2 is plates move past each other sideways
Explanation:
Q12. How much force is applied on the body when 150 joule of work
is done in displacing the body through a distance of 10m in the
direction of force?
Force = Work/distance
Force = 150/10
= 15 Newtons
Force = 15 Newtons
Therefore, 15 newtons of force is applied to the body when 150 joules of work
is done in displacing the body through a distance of 10m in the direction of the force.

1. How much heat is produced if you heat .25 kg water from 25 degrees C to 100 degrees C. The specific heat of water is 4180 J/kg C.
Answer:
Q = 78375 [J]
Explanation:
To solve this problem we must use the following ideal equation for the thermal energy of an element or substance depending on the temperature change.
[tex]Q=m*C_{p}*(T_{final}-T_{initial})[/tex]
where:
Q = heat [J]
m = mass = 0.25 [kg]
Cp = specific heat = 4180 [J/kg*C]
Tinitial = 25[°C]
Tfinal = 100 [°C]
[tex]Q =0.25*4180*(100-25)\\Q = 78375 [J][/tex]

HELP PLEASE BOYLES LAW
Answer:
3 L
Explanation:
From the question given above, the following data were obtained:
Initial volume (V₁) = 2 L
Initial pressure (P₁) = 0.75 atm
Final pressure (P₂) = 0.5 atm
Final volume (V₂) =?
Using the Boyle's law equation, the new volume (i.e final volume) of the Ne gas can be obtained as:
Initial volume (V₁) = 2 L
Initial pressure (P₁) = 0.75 atm
Final pressure (P₂) = 0.5 atm
Final volume (V₂) =?
P₁V₁ = P₂V₂
0.75 × 2 = 0.5 × V₂
1.5 = 0.5 × V₂
Divide both side by 0.5
V₂ = 1.5 / 0.5
V₂ = 3 L
Thus, the new volume of the Ne gas is 3 L
what is potential displacement?
Answer:
The answer to this question is given below in this explanation section.
Explanation:
"potential displacement"
in geometry and mechanics a displacement is a vector whose length is a shortest distance from the initial to the final position of a point p undergoing motion.it quantifies both the distance and direction of the net or total motion along a straight line from the initial position to the final position of the point trajectory.A displacement may be identified with the translation that maps the initial position to the final position.
A displacement ,may also described as a relative position that is as the final position xf of the point to the point relatively to its initial position xi.The corresponding displacement vectors can be defined as the difference between the final and initial positions.
s=xf-xi=Δx
in considering motion of objects over time,the instantaneous velocity of the object is the rate of change of the displacement as a function of time.The instantaneous speed then is distinct from velocity or the time rate of change of the position vector.if one considers a moving initial position or equivalently a moving origin.
From motion over a given interval of time,the displacement divided by the length of the time interval defines the average velocity which is a vector and differ thus from the average speed,which is a scalar.

Why is it generally easy to filter out particles in suspension?
Answer: A suspension is a heterogeneous mixture in which some of the particles settle out of the mixture upon standing. The particles in a suspension are far larger than those of a solution, so gravity is able to pull them down out of the dispersion medium (water).

Static stretching is done by slowly moving a joint towards its maximum range of motion. You will feel a gentle pulling sensation in the muscle being stretched.
True or False
Answer:
True
Explanation:
It is true that you will feel a gentle pulling sensation in the muscle being stretched when Static stretching is done by slowly moving a joint.
What is static stretching?Static stretching is most likely the most well-known and time-honored method of stretching. This entails extending a muscle to its maximum length and then maintaining that position for at least 15 to 20 seconds.
With each stretch, the emphasis is frequently on focusing on a specific muscle group.
Hence it is true that you will feel a gentle pulling sensation in the muscle being stretched when Static stretching is done by slowly moving a joint.

A child tugs on a rope attached to a 0.62 kg toy with a horizontal force of 16.3 N. A puppy pulls the toy in the opposite direction with a force of 15.8 N. What is the acceleration of the toy
Answer:
[tex]a=51.77\ m/s^2[/tex]
Explanation:
Given that,
The mass of a toy, m = 0.62 kg
Force with which a child pull the toy = 16.3 N
The force with which the toy pulled in the opposite direction = -15.8 N
We need to find the acceleration of the toy. Let F be the net force acting on the toy. It is equal to :
F = 16.3 N - (-15.8 N)
= 32.1 N
Let a be the acceleration of the toy. Using Newton' second law of motion to find it.
F = ma
[tex]a=\dfrac{F}{m}\\\\a=\dfrac{32.1}{0.62}\\\\a=51.77\ m/s^2[/tex]
So, the acceleration of the toy is [tex]51.77\ m/s^2[/tex].

So the word equation is as follows;
Magnesium oxide + carbon ----> carbon dioxide + magnesium
In a sentence form;
One mole of magnesium oxide reacts with one mole of carbon to yield one mole of carbon dioxide and one mole of magnesium metal.

Explanation:
An electric heater is rated at 1500 W. If the heater is rated as 80% efficient, calculate the output
rate of energy
Answer:
Power = 1200 [W].
Explanation:
The efficiency of an electrical equipment is defined as the relationship between the power realized, over the power that is consumed. For this case, they give us the data of consumed power and efficiency in this way we can calculate the power that the equipment performs.
[tex]Efficency=\frac{Power_{done}}{P_{consumed}}\\0.8 = \frac{Power_{done}}{1500} \\Power_{done}=1500*0.8\\Power_{done} = 1200 [W][/tex]
This means that of the 1500 [W], 1200 [W] are actually used to get the job done. This is established by means of the first law of thermodynamics.

Assuming a constant force, and hence a constant acceleration a, we have by Newton's second law,
4.0 N = (1.2 kg) a → a = (4.0 N) / (1.2 kg)
and by definition of average velocity,
a = (5.0 m/s - 2.0 m/s) / t
where t denotes the time for which the force is applied.
So,
(4.0 N) / (1.2 kg) = (3.0 m/s) / t → t = (3.0 m/s) (1.2 kg) / (4.0 N) = 0.90 s
