- The school zone in front of your school has a posted speed limit of 25 mi/h, which is about 11 m/s. Let's
examine the stopping of a car in several different situations.
a. The crossing guard holds up her stop sign, and the driver is paying attention well. The car moves at a
constant velocity of 11 m/s for 2.3 seconds while the driver reacts, then slows down at a constant rate
of -4.5 m/s2. What is the stopping distance for the car in this situation?
Answer:
s = 38.7 m
Explanation:
First we calculate the distance covered during uniform motion of reaction time.
s₁ = vt
where,
s₁ = distance covered during uniform motion = ?
v = uniform speed = 11 m/s
t = time = 2.3 s
Therefore,
s₁ = (11 m/s)(2.3 s)
s₁ = 25.3 m
Now, we calculate the distance covered during decelerated motion:
2as₂ = Vf² - Vi²
where,
a = deceleration = -4.5 m/s²
s₂ = distance covered during decelerated motion = ?
Vf = Final Velocity = 0 m/s
Vi = Initial Velocity = 11 m/s
Therefore,
2(-4.5 m/s²)s₂ = (0 m/s)² - (11 m/s)²
s₂ = (-121 m²/s²)/(-9 m/s²)
s₂ = 13.4 m
the total distance will be:
s = s₁ + s₂
s = 25.3 m + 13.4 m
s = 38.7 m
What is an atom? What it is made of? Explain with a paragraph.
Answer:
An atom makes up almost everything; it is the building block of this universe. An atom is made out of protons, electrons, and neutrons. Protons are positively charged particles, Electrons are negatively charged particles, and Neutrons are neutral. The protons, and neutrons are found in the very center of the atom, which is called the nucleus. The electrons orbit the nucleus.

The 500 pages of a book have a mass of 2.50 kg. What is the mass of each page A in kg B in mg?
Answer:
A.
Mass per page = mass of book / number of pages
Mass per page = 2.5kg / 500 pages = 0.005kg
B.
Mass per page = mass of book / number of pages
Total mass = 2.5kg = 2,500grams = 2,500,000mili grams
Mass per page = 2500000mg / 500 pages = 5000mg
If size of an image is 10 cm and the magnification produced by a mirror is +1, what will be the size of object?
Answer:
h = 10 cm
Explanation:
The magnification produced by a mirror is given by :
[tex]m=\dfrac{h'}{h}[/tex]
h' is the image size and h is the object size
We have, h = 10 cm, m = +1
So,
[tex]m=\dfrac{h'}{h}\\\\h=\dfrac{10}{1}\\\\h=10\ cm[/tex]
So, the size off the object is same as that of the size of the image i.e. 10 cm.

The elements least likely to form bonds are found in which group?
O 15
O 16
017
O 18
The element that is least likely to form bonds is found in group 18. Thus, the correct option for this question is D.
What is group 18 of the periodic table known?The elements of group 18 in the modern periodic table are known as noble gases. These gases are colorless, odorless, tasteless, and nonflammable under standard conditions.
They were once labeled group 0 in the periodic table because it was believed they had a valence of zero, meaning their atoms cannot combine with those of other elements to form compounds.
Due to this fact, they would not have any ability to form bonds with other elements in order to produce compounds or molecules. They are the most stable elements because they have a full outer shell of valence electrons, so they have no need to bond with other elements.
Therefore, the element that is least likely to form bonds is found in group 18. Thus, the correct option for this question is D.

An ant is Dragging a Housefly and Elephant is pushing a big tree which is not moving. who is doing work? The ant or the elephant? Justify Your Answer!
Answer:
the ant
Explanation:
because work is done when there will be involvement of displacement in the direction of the force.
Answer:
The ant is doing work but the elephant is not
Explanation:
Work done = Force × Displacement
In case of ant and housefly,
Ants are dragging the housefly , so they are displacing the housefly from one point to the other by applying certain force , so we can say that they are doing work
In case of elephant and tree,
When the elephant is pushing the tree( applying force) , the tree is not moving which means that there is no Displacement, so work done will be
Work done = Force × Displacement
= Force × 0
= 0

Answer:
can someone help me with physics to
Answer:
equation D=mass/volume
D=m/v
example sample : D=m/v= 250/100 = 2.5 g/cm³
1- D=m/v = 454/2274 = 0.2 g/cm³
2- 1 liter = 1000 cm³
D=m/v=1000/1000= 1 g/cm³
3 - d=m/v
0.6 g/cm³=m / 1.2 cm³
m=0.6*1.2 = 0.72 g
4: a:171/15 = 11.4 g/cm^3 lead
b:148/40 = 3.7 g/cm^3 Aluminum
c:475/250 =1.9 g/cm^3 Bone

Quiz 1
As shown in the figure below, Justin walks from the house to his truck on a windy day. He walks 20 m
toward the truck, 15 m back to retrieve his wind-blown hat, and another 20 m to reach the truck. He
walked a total time of 75 s.
20 m
15 m
20 m
What is Justin's average velocity over the 75 s period?
Answer:
v = 1/3 m / s = 0.333 m / s
in the direction of the truck
Explanation:
The average speed is defined by the variation of the position between the time spent
v = Δx / Δt
since the position is a vector we must add using vectors, we will assume that the displacement to the right is positive, the total displacement is
Δx = 20 - 15 +20
Δx = 25 m
therefore we calculate
v = 25/75
v = 1/3 m / s = 0.333 m / s
in the direction of the truck

Answer:
4 seconds
Explanation:
Given:
v₀ = 12 m/s
v = 32 m/s
a = 5 m/s²
Find: t
v = at + v₀
32 m/s = (5 m/s²) t + 12 m/s
