A Tale f Two Elephants

1. what organisms are shown?

2. Do they look the same?

3. Do the pictures show the same species?

4. How are they similar?

5. How are they different?​

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 element that is least likely to form bonds is found in group 18. Thus, the correct option for this question is D.

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.

Answer:

Explanation:

a particular kind of matter with uniform properties.

Answer:

a particular kind of matter with uniform properties or the real physical matter of which a person or thing consists and which has a tangible, solid presence.

Explanation:

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.

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:

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

t = 4 s

0 to 60 mph in 4.5 seconds

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

   d: 680/1000 = 0.68 g/cm^3   Gasoline (lithium)

5: the density of a substance equal to the mass of the substance divide by volume

The answer is increase.

d = m/v. if you increase the mass without changing the volume, the density will increase.

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

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.

Answer:

What is Justin’s average velocity over the 75 s period?

Answer: 0.33  m/s

What is Justin’s average speed over the 75 s period?

Answer: 0.73  m/s

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
