Answer:
1 / 3 or 0.33
that is if you meant that the object accelerates at 3 m / s² not 3 m / s
for the unit of acceleration is m / s²
Explanation:
m = ?
a = 3
f = 1N
where;
m = mass ( kg )
a = acceleration ( m / s² )
f = force ( N )
from all the parameters we are given, we can use Newton's second law of motion to solve it
that is;
a = f / m
to make m the subject of the formula, we have to cross multiply to give us;
m( a ) = f
divide through by a to give us;
m ( a ) / a = f / a
therefore,
m = f / a
so, we substitute our values to give us;
m = 1 / 3
therefore. m = 1 / 3 or 0. 33
hope this helps
thank you!!!!
How much work is done on an object that is moved to acquire a displacement of 5 meters when 500 Newtons of force was exerted?
Answer:
2,500 Joules (J) or Newton Meter (N M)
Explanation:
Work = Force x Distance
The force in this equation is 500 Newtons. The distance (displacement) is 5 meters. Plug it into the equation above.
Work = 5m x 500n
Work = 2,500 Joules or Newton-Meters.
Therefore 2,500 Joules or Newton Meters of work is done on an object.

Answer:
acceleration = 3v 125 m/s^
final speed= 50 m/s
final speed in km/hr = 180 km/hr
Explanation:
A new model BMW can start from rest and travel 400 m in 16 s.then the acceleration during this time would be 1.5625 m/s²
What are the three equations of motion?There are three equations of motion given by Newton
The first equation is given as follows
v = u + at
the second equation is given as follows
S = ut + 1/2×a×t²
the third equation is given as follows
v² - u² = 2×a×s
As given in the problem, A new model BMW can start from rest and travel 400 m in 16 s
distance covered by BMW = 400meters
initial velocity(u) = 0 m/s
time = 16 seconds
acceleration(a) =? m/s²
By using the second equation of motion given by newton
S = ut + 1/2at²
S = 400 m ,u= 0 m/s , and t =16seconds
400 = 0 + a16²
a =400/256
a = 1.5625 m/s²
For the final speed of the car
v= u + at
v = 0 + 1.5625×16
v = 25 m/s
For calculating the speed in km /h
v = 25 ×3600/1000
= 90 km/h
Thus, the acceleration during the first 16 s time would be 1.5625 m/s²

A block of mass 1kg is placed on an inclined plane at an angle of 30° to the horizontal. Calculate the frictional force, normal reaction, the coefficient of the static friction
Question:
A block of mass 1kg is placed on an inclined plane at an angle of 30° to the horizontal. Calculate the frictional force, normal reaction, the coefficient of the static friction
Answer:
Break the mg force into components in the plane of the inclined plank. Now force acting parallel is mgsin37°. Perpendicular force is mgcos37° which is equal to normal force.
Now calculate max value of friction force which is 0.8*mg cos37°. Since its greater than pulling force mgsin37°, the body will be at rest and acceleration is zero.
Force applied by surface is vector sum of normal force and friction force acting.

1-Atoms with few valence electrons
tend to lose them and then the next
energy will be the outer level and it is
full. This is more stable for the atom.
Remember that atoms are neutral,
which means that they have the
same number of positive protons and
negative electrons. If an electron is
lost, the atom will no longer be
neutral. What will happen to the
valence electron of Na and what will
it form? What will the resulting
charge be?
Answer:
An atom that loses one or more valence electrons to become a positively charged ion is known as a cation, while an atom that gains electrons and becomes negatively charged is known as an anion.
Explanation:
Atoms that lose electrons acquire a positive charge as a result because they are left with fewer negatively charged electrons to balance the positive charges of the protons in the nucleus.

What is the total distance travelled? What is the displacement of the object?
Hi there!
Distance and displacement are different.
Distance is WITHOUT direction (scalar quantity)
Displacement TAKES INTO ACCOUNT direction (vector quantity), and is RELATIVE to the initial point.
DISTANCE:
Add up each segment's position:
0 - 2 sec: 0 m
2 - 5 sec: 10 - 4 = 6 m
5 - 6 sec: 0 m
6 - 8 sec: 10 - 2 = 8 m
8 - 9 sec: 0 m
9 - 12 sec: 5 - 2 = 3 m
Add up:
6 + 8 + 3 = 17 m
DISPLACEMENT:
To find displacement, simply look at the position at the final point (t = 12 sec) and compare to the initial position:
At t = 12: Position = 5 m
At t = 0: Position = 4 m
5 - 4 = 1 m

An object has an acceleration of 12.0 m/s/s. If the net force
acting upon this object were tripled, then its new acceleration
would be m/s/s.
Answer:
F=ma
Explanation: Let X stand for the new acceleration with the tripled force.
F = m*(12.0 m/s/s)
3F = m*(X)
3F = 3*m*(12.0 m/s/s)
3F = m*(X)
3F = m*(3*12.0 m/s/s)
X = (3*12.0 m/s/s)
a for 3X the force is = (3*12.0 m/s/s), or 36.0 m/s/s

Students take measurements of the force F0 , directed to the left, needed to hold the cart in place as well as the tension FT in the horizontal section of string. The students take three measurements for each force. Write down the sets of measurements that would provide the most precise determination of the correct relationship between the net force and the vector sum of the individual forces exerted on the cart?
The characteristics of the random error allow to find the result for the best value of the forces is:
Using the average values gives the best results.
In a measurement in physics some type of instrument is used, therefore all measurements have a precision due to the minimum amount that can be measured with the given instrument, the correct way to give the measurement is
m = m ± Δm
Where m is the measure and Δm the error due to the appreciation of the instrument.
In the measurement process there are variables type that can affect the results, in general they can be divided into two groups:
Systematic errors. They are problems that can be reduced or solved, in general they move the result to a specific side, for example: calibration problems, problems with the measurement method, etc. Random errors. They are variables that change during the measurement that cannot be foreseen or controlled, for example: temperature, humidity, deformation of bodies, etc.
Statistical methods can be applied to the random type of processes to reduce their effect on the final result, one of the most efficient way is to carry out the measurement several times and since the errors are random, if we obtain the average it must be closer to the true value.
[tex]m_{average} = \frac{\sum m_i}{n}[/tex]
Where m_i is each measurement and n is the number of measurements.
As a result it is
[tex]m = m_{average} \pm \sigma[/tex]
Where σ is the standard deviation.
It indicates that three measurements were made of each force, suppose that their values are: F₀₁, F₀₂ and F₀₃, and the best value is
[tex]F_{o \ average} = \frac{1}{3} (F_{o1} + F_{o2} + F_{o3} )[/tex]
For the tension of the body also takes three measurements.
[tex]F_{t \ averag} = \frac{1}{3} (F_{t1} + F_{t2} + F_{t3} )[/tex]
The best value of the net forces should be obtained using the average values.
[tex]\Delta F = F_{t \ average} - F_{o \ average}[/tex]
In conclusion using the characteristics of the random error we can find the result for the best value of the forces is:
Using the average values gives the best results.
