wat is the difference between resultance and equilibrum
Answers
Explanation:
A resultant force is the sum of the forces on an object.
Forces are said to be in equilibrium when the resultant force is zero. This means the object will not accelerate.

Force = Mass x Acceleration
i. Mass as subject.
ii. Acceleration as subject.
Answers
Answer:
1) mass = force / acceleration
2) acceleration = force / mass
Explanation:
Part 1)
Force = Mass x Acceleration
Divide both sides by acceleration
force / acceleration = mass
mass = force / acceleration
Part 2)
Divide both sides by mass
force / mass = acceleration
acceleration = force / mass

~AH1807Peace!A wombat runs south in a straight line with an average velocity of 5 m/s for 4
minutes and then with an average velocity of 4 m/s for 3 minutes in the same
direction.
What is the wombats total displacement?
What is the average velocity during that time?
Answers
We have that
The wombats total displacement is
[tex]d_t=2100m[/tex]
The average velocity during that time is
[tex]v_{avg}=5m/s[/tex]
From the question we are told that:
initial Velocity [tex]V_1=5m/s[/tex]
initial Time [tex]T_1=4min=>240sec[/tex]
Final Velocity [tex]V_2=4m/s[/tex]
Final time [tex]T_2=3min=>180sec[/tex]
a)
Generally, the equation for displacement is mathematically given by
d_t=(Initial +final) displacement
Where
initial displacement
[tex]d_1=V_1*t_1\\\\d_1=5*240[/tex]
[tex]d_1=1200m[/tex]
Final displacement
[tex]d_2=V_2*t_2\\\\d_2=5*180[/tex]
[tex]d_2=900m[/tex]
Therefore
[tex]d_t=(Initial +final) displacement[/tex]
[tex]d_t=1200+900[/tex]
[tex]d_t=2100m[/tex]
b)
Generally, the equation for Average velocity is mathematically given by
[tex]v_{avg}=\frac{d_t}{t_1+t_2}[/tex]
[tex]v_{avg}=\frac{2100m}{240+180}[/tex]
[tex]v_{avg}=5m/s[/tex]
in conclusion
The wombats total displacement is
[tex]d_t=2100m[/tex]
The average velocity during that time is
[tex]v_{avg}=5m/s[/tex]

PLEASE HELP DUE IN ALMOST AN HOUR PLEASE
Answers
Answer:
Below
Explanation:
4. You can use this formula to calculate the acceleration of an object
acceleration = velocity / elapsed time
Plugging our values in....
acceleration = 1700 m/s / 25 s
= 68 m/s^2
5. You can use this formula to calculate the final velocity of an object
finalvelocity = initialvelocity + (acceleration) (time)
Plugging our values in....
finalvelocity = 1.5 m/s + (2.4 m/s^2) ( 3 seconds)
= 8.7 m/s

During which portion of its motion-A, B, or C- does the train have the smallest speed?
Answers
Answer:
1
Explanation:
B is -1 m/s but it transfers to 1
During portion B of its motion, the train would have the smallest speed because the slope of the position time graph is the lowest for portion B.
What is speed?The total distance covered by any object per unit of time is known as speed. It depends only on the magnitude of the moving object.
As given in the problem we have to find out for which portion of the motion the train would have the smallest speed,
As we know that speed is given by the slope of the position-time graph.
For portion C the slope of the given position-time graph is highest therefore the speed of the train would be largest for portion C.
For portion B the slope of the given position-time graph is lowest therefore the speed of the train would be lowest for portion B.

Explanation:
No, sound waves cannot travel in a vacuum. This is because sound waves are mechanical waves that need a medium (such as air and water) to travel. Sound in physics is defined as a vibration that propagates as an audible wave of pressure, through a medium such as a gas, liquid or solid.

If a ball is rolling at a velocity of 1.5 m/s and has a momentum of 10.0 kg times m/s, what is the mass of the ball?
Answers
Answer:
Mass of the ball, M = 6.667 kg
Explanation:
Given data:
Momentum, Mo = 10.0 kgm/s
Velocity of the rolling ball, V = 1.5 m/s
Mass of the body, M = ?
Momentum, Mo = Mass, M x Velocity, V
10.0 kgm/s = M x 1.5 m/s
Divide each side by 1.5 m/s
M = 10.0 kgm/s / 1.5 m/s
M = (6⅔) kg
:. Mass of the ball, M = 6.667 kg
