Answer:
2.6 seconds
Explanation:
You have to divide the distance by the velocity to find the time:
46/18 = 2.55 ≈ 2.6 seconds
The answer you are looking for is approximately 2.6 seconds.
Solution/Explanation:
To get the correct answer, you must divide the distance and velocity.
This means that 46÷18=2.5556.
2.5556≈2.6.
So, therefore, the final answer is approximately 2.6 seconds.
I hope that this has helped you. Enjoy your day, and take care.

PLEASE HELP DUE IN ALMOST AN HOUR PLEASE
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

1000 mm =
covert the following into metres with working
Answer:
1m
Explanation:
The conversion is 1mm = 0.001m. So all we need to do to find how many mm there are in a meter, all we need to do is divide by a 1000;
1000 / 1000 = 1m

Why is the sun considerad as the main source of energy?
Answer:
The sun is considered as the main source of energy since it is the source of nearly all the earth's energy. Plants produce food using sunlight, and the food we get from plants and animals also has its primary sunlight source.
Hoped it helps you.
Answer:
It is because it supplies most of our energy that we use today, directly or indirectly. It radiates light and heat or solar energy, which makes it possible to exist life on earth.

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?
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]

During which portion of its motion-A, B, or C- does the train have the smallest speed?
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.

wat is the difference between resultance and equilibrum
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.
what's is meant by relative motion?
Relative motion means a motion relative to a reference point. We can also say, relative motion means motion referred or observed from a reference point.
For example, Alex is in a train and Ace is at the station, when the train starts moving, for Ace it is moving at a speed of 10 m/s, but for Alex it is moving at 0 m/s, or we can say that it is at rest for Alex, but in motion for Ace. This is relative motion.
Answer:
relative motion is the motion of an object compared to that of another object.for example two cars driving in the same highway in the same direction.

science (Friction/Forces)
which option is correct?
Answer:
A
Explanation:
At constant speed, acceleration=0
From the formula, Fnet=ma (Resultant force= mass x acceleration), sub a=0
Fnet=0
Since the resultant force=0, the pushing force is equal to the frictional force
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?
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

can sound waves propagate in vacuum if yes why if no why not??
Answer:
please mark me brainliest
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.
