Benjamina started her walk from the front door of her ground-floor apartment. She walked 6 meters to the corner of the building and then turned the corner and walked 10 meters to her friend’s apartment. Identify the difference between the distance she walked and her displacement.
Answer:
The change in her position (from beginning to end), along with the direction, is considered her displacement.
Explanation:
Answer:
The change in her position ( from beginning to end), along with the direction, is considered her displacement. This value is a measurement and a direction. The total distance along the path from her starting point to her endpoint is considered her distance. This value is a measurement only.
A student walks to the right, 25-m along the C Hall in 15-s. They turn around and walk 15-m to the left in 8.0-s. What is the average speed and the average velocity? (V represents average speed and ΔV represents average velocity)
For the student that walks to the right 25 m in 15 s and then turns and walks to the left 15 m in 8.0 s, we have:
1. The average speed is 1.74 m.
2. The average velocity is 1.42 m.
1. The average speed is an scalar wich is given by:
[tex] V = \frac{d_{t}}{t_{t}} [/tex]
Where:
[tex]d_{t}[/tex]: is the total distance
[tex]t_{t}[/tex]: is the total time
The total distance and the total time can be calculated as follows:
[tex]d_{t} = d_{1} + d_{2} = 25 m + 15 m = 40 m [/tex]
[tex] t_{t} = t_{1} + t_{2} = 15 s + 8.0 s = 23 s [/tex]
Since V is a scalar, the direction of motion is not important to calculate the final value.
Then, the average speed is:
[tex] V = \frac{d_{t}}{t_{t}} =\frac{40 m}{23 s} = 1.74 m/s [/tex]
2. The average velocity is a vector, so the direction of motion is important here. This ΔV can be calculated with the following equation:
[tex] \Delta V = \frac{\Delta x}{\Delta t} = \frac{x_{f} - x_{i}}{t_{f} - t_{i}} [/tex]
Where:
x: is the displacement
f: is for final and i: is for initial
Hence, the average velocity is:
[tex] \Delta V = \frac{x_{f} - x_{i}}{t_{f} - t_{i}} = \frac{15 m - 25 m}{8.0 s - 15 s} = 1.42 m/s [/tex]

show that vector a + vector b = vector b + vector a.
Recall that vector addition can be visually represented by the head-to-tail method. This means that the head of one vector is glued to the tail of the other vector, to point us directly to the target vector we're after. Think of it like following instructions on a map.
A visual example is shown below. There are two pathways to arrive at the c = a+b vector. The patheway on the right is a+b while the path on the left is b+a. The order doesn't matter since we arrive at the same destination.
-------------------------------------
Here's an algebraic approach without the need of a drawing.
Consider that vectors a and b are defined like so
a = <p,q>
b = <r,s>
where p,q,r,s are real numbers. They define the coordinates of the two vectors.
Adding vectors a and b gets us
a+b = <p,q>+<r,s> = <p+r,q+s>
We add the corresponding coordinates. Since p+r is the same as r+p, we can say,
b+a = <r,s>+<p,q> = <r+p,s+q> = <p+r,s+q> = a+b
Therefore, a+b = b+a. Again, this all relies on the fact that addition of scalar numbers can be done in any order. So by extension, vector addition can be done in any order. This applies to multiple vectors and not just two of them.

A wheelbarrow of mass 20 kg accelerates from rest and reaches speed of 10m/S2 in 5 seconds.its force?
Answer:
[tex]\boxed {\boxed {\sf 40 \ Newtons}}[/tex]
Explanation:
We are asked to find the force of a wheelbarrow. According to Newton's Second Law of Motion, force is the product of mass and acceleration.
[tex]F= \ m \times a[/tex]
1. Calculate AccelerationThe mass of the wheelbarrow is 20 kilograms. We are not given the acceleration, so we must calculate it using the following formula.
[tex]a= \frac{v_f-v_i}{t}[/tex]
The wheelbarrow starts at rest or 0 meters per second (initial velocity) and accelerates to reach 10 meters per second (final velocity) in 5 seconds (time).
[tex]v_f=[/tex]10 m/s [tex]v_i=[/tex]0 m/s t= 5 sSubstitute these values into the formula.
[tex]a= \frac{ 10 \ m/s-0 \ m/s}{5 \ s}[/tex]
Solve the numerator.
[tex]a= \frac{10 \ m/s}{5 \ s}[/tex]
Divide.
[tex]a= 2 \ m/s/s[/tex]
[tex]a= 2 \ m/s^2[/tex]
2. Calculate ForceNow we know the mass and acceleration of the wheelbarrow
m= 20 kg a= 2 m/s²Substitute the values into the force formula.
[tex]F= 20 \ kg \times 2 \ m/s^2[/tex]
[tex]F= 40 \ kg*m/s^2[/tex]
Convert the units. 1 kilogram meter per square second is equal to 1 Newton, so our answer of 40 kilogram meters per square second is equal to 40 Newtons.
[tex]F= 40 \ N[/tex]
Answer:
40 N
Explanation:
We know that
F = ma
and
a = (v - u)/t
So,
F = m(v - u)/t
F = 20(10 - 0)/5
F = 20(10/5)
F = 20(2)
F = 40 N

A bowling lane is 18 meters long. How long would it take a 1.5 m/s bowling ball to
roll down that lane?
16.5 seconds
16.5 meters
12 seconds
27 seconds
27 meters
12 meters
Divide distance by speed:
18 meters / 1.5 meters/ second = 12 seconds
Answer: 12 seconds
A bowling lane is 18 meters long. it would take 12 seconds for a 1.5 m/s bowling ball to roll down that lane, therefore the correct answer is the third option
What is Velocity?The total displacement covered by any object per unit of time is known as velocity. It depends on the magnitude as well as the direction of the moving object.
The mathematical expression for velocity is given by
velocity= total displacement/Total time
As given in the problem a bowling lane is 18 meters long and the ball is moving with a velocity of 1.5 m/s in the roll-down lane we have to find the time period for the bowling ball to roll down that lane
Total displacement = 18 meters
the velocity of the ball = 1.5 m/s
time =?
By substituting the values in the formula of the velocity
1.5 = 18/t
t= 12 seconds
Thus , it would take 12 seconds for a 1.5 m/s bowling ball to roll down that lane

Explain an experiment you could run to test the Big Bang theory, including the design and execution, and any observations you can make of the world around you related to the scientific theory. And explain how the observations support of refute the theory!!! Will mark branliest
The big bang theory or great expansion explains the formation of the universe from a point with very high density where matter and space were created, it can be observed in an experiment
The Big Bang theory that can be adapted with some home experiments, specifically the expansion can be measured using an experiment with inflating balloons.
Materials
deflated balloons
marker
thread
measuring tape
Description of the experiment
The stars or galaxies are marked repeatedly with an initial separation and this distance is measured by a thread the length and the thread with a meter, this is used as measured by the fact that the surface is curved.
The balloon is inflated and measurements of the separation are made, observing that as the volume of the balloon increases (time increase) the separation of the galaxies increases
The increase in distance is explained by the Big Bang theory or great expansion.
There is also astronomical evidence:
* The redshift of the hydrogen spectral lines that is explained by the Dopler effect, which is a move away from objects
* Background radiation in the microwave range that comes from everywhere and would be the residue of a large initial explosion.

8. A girl is padaling her blcycle at a velocily of 0.10 km/min. How far will she travel in two hours?
Explanation:
2 h = 120 min
v = 0.1 km/m
distance = v × t
= .1 × 120
= 12 km
The speed of an object undergoing constant acceleration increases from 8.0 meters per second to 16.0 meters per second in 10. seconds. How far does the object travel during the 10. seconds?
Answer:
[tex] \boxed{d = 120\: meters} [/tex]
Explanation:
Given:
[tex] v_{0} [/tex] = 8.0 m/s[tex] v [/tex] = 16.0 m/s[tex] t [/tex] = 10 seconds[tex] d [/tex] = ?We can use this equation with the variables given to solve:
[tex] d \: = \frac{t \: (v + v_{0})}{2}[/tex] →
[tex] d \: = \frac{(10s) \: ((16.0 \: m/s) + (8.0 \: m/s))}{2} [/tex] →
[tex] d \: = \frac{(10s) \: (24 \: m/s)}{2} [/tex] →
[tex] d \: = \frac{(10 \: s \: • \: 24 \: m/s)}{2} [/tex] →
[tex] d \: = \frac{240 \: m}{2} [/tex] →
[tex] d \: = 120 \: m [/tex]
The distance traveled by the object in 10 seconds is 120 meters.
Given to us,
Final velocity of the object, [tex]v= 16\ meter/sec[/tex]
Initial velocity of the object, [tex]u= 8\ meter/sec[/tex]
Time for traveling, [tex]t= 10\ sec[/tex]
Using the first equation of motion, we can find out acceleration of the object [tex]a[/tex],
[tex]v=u+at\\16=8+a\times 10\\a= 0.8\ meter/sec^2[/tex]
Now using the second equation of motion and putting the value of [tex]a[/tex],
The distance[tex](S)[/tex] traveled by the object ,
[tex]\begin{aligned}S&= ut+\frac{1}{2}at^2\\&= 8\times 10+ \frac{1}{2}\times 0.8\times 10^2\\&= 120\ meters \\\end{aligned}[/tex]
Hence,The distance traveled by the object in 10 seconds is 120 meters.
