Answer:
Explanation:
No, not any of these substance will float in Methanol , simply because Methanol has a density of 0.79 g, if you put any substance that weighs more than 0.79 g, it will sink, it all depends on the weight if it is more or less than methanol
2: D=m/v
D=135/50 = 2.7 g/cm³ ( Aluminum)
D=M/V
if two objects has the same mass but one has larger volume, then te one with larger volume has less density
example : 2 objects
mass of both=350
volume of the first one=500 and the other 750
D1=M1/V1 = 350/500 =0.7
D2 = M2/V2 = 350/750 = 0.4666

3. Do the pictures show the same species?
4. How are they similar?
5. How are they different?
Answer:
u need it now?
Explanation:
I'll answer it
Based on the diagram above, the organisms that are shown are elephants.
What is a species?A species simply refers to a biological classification of related organisms that have the same (similar) characteristics and they are capable of mating (breeding) with one another in a cycle (different seasons).
Based on the diagram above, we can logically deduce that the organisms shown are species of elephants and they look similar due to the following points:
They both have a single tail.They both have ears.They both have four legs.They both have tusk.However, an obvious difference between them is the number of tusk.

Explanation:
A 3.00 kg mass is traveling at an initial speed of 25.0 m/s. What is the
magnitude of the force required to bring the mass to rest in a distance of 62.5m?
Answer:
The magnitude of the force required to bring the mass to rest is 15 N.
Explanation:
Given;
mass, m = 3 .00 kg
initial speed of the mass, u = 25 m/s
distance traveled by the mass, d = 62.5 m
The acceleration of the mass is given as;
v² = u² + 2ad
at the maximum distance of 62.5 m, the final velocity of the mass = 0
0 = u² + 2ad
-2ad = u²
-a = u²/2d
-a = (25)² / (2 x 62.5)
-a = 5
a = -5 m/s²
the magnitude of the acceleration = 5 m/s²
Apply Newton's second law of motion;
F = ma
F = 3 x 5
F = 15 N
Therefore, the magnitude of the force required to bring the mass to rest is 15 N.

Which explains how to calculate the average acceleration of a moving object?
1.Divide the change in velocity by the change in time.
2.Multiply the change in time by the change in velocity.
3.Divide the change in time by the change in velocity.
4.Subtract the velocity from the change in time.
Answer Multiply the acceleration by time to obtain the velocity change: velocity change = 6.95 * 4 = 27.8 m/s . Since the initial velocity was zero, the final velocity is equal to the change of speed.

The minus sign indicates the average velocity is also toward the rear of the plane.
The average velocity of an object does not tell us anything about what happens to it between the starting point and ending point, however. For example, we cannot tell from average velocity whether the airplane passenger stops momentarily or backs up before he goes to the back of the plane.

A force of 200N is creating a pressure of 50Pa on a surface. Calculate the area of the surface.
Answer:
4kg
Explanation:
pressure=50pa
force=200N
Area=?
now,
pressure=force/area
50=200/area
area=200/50
area=4kg
The pressure is the forces acting on a given area. Hence, the area of the surface with a pressure of 50 Pa by a force of 200 N is 4 m².
What is force?Force is an external agent acting on a object to deform it or to change its state form motion or rest. Force is a vector quantity and it is characterised by its magnitude and direction. The unit of force is Newton (N).
Pressure is the force applied on unit area. Thus, as the force increases, pressure increases. Pressure can have the units in atm, pa, N/m² etc.
Pressure = Force / area.
Given that force = 200 N
pressure = 50 Pa = 50 N/m²
Therefore, area = force/pressure
= 200 N / 50 Pa
= 4 m²
Therefore, the area of the surface is 4 m².

What is the smallest part of a chemical compound that has all the properties
of that compound
A. A nucleus
B. A mineral
C. An atom
D. A molecule
Answer:
D. A Molecule
Explanation:
The smallest particle of a compound that still has the properties of the compound is a molecule. It is composed of two or more bonded atoms.
The smallest part of a chemical compound that has all the properties of that compound is a molecule (option d)
In the world of chemistry, substances are composed of tiny units called atoms, and these atoms bond together to form chemical compounds.
Option A, a nucleus, refers to the central core of an atom and consists of protons and neutrons. While essential for an atom, a nucleus alone does not represent a complete chemical compound.
Option B, a mineral, is a naturally occurring inorganic substance with a specific chemical composition and a definite atomic structure. However, minerals are not the smallest parts of a chemical compound.
Option C, an atom, is the fundamental building block of matter. It consists of a nucleus (containing protons and neutrons) surrounded by electrons. While atoms are crucial for forming compounds, they are not the smallest unit that retains all the properties of a compound.
Therefore, the correct answer is Option D, a molecule. A molecule is a group of two or more atoms bonded together, representing the smallest part of a chemical compound that possesses all the characteristics and properties of that compound.
Hence the correct option is (d).

An object is moving along a straight line. The graph shows the velocity of the object over
time.
What is the instantaneous acceleration of the object at time = 9.5 seconds?
A.-20 m/s2
B.0 m/s2
C.20 m/s2
D.-10 m/s2
Answer:
From 9 to 10 sec the velocity is decreasing at a constant rate.
Change in V = 20 m/s - 30 m/s = -10 m/s
Since acceleration is constant from point E to point F (straight line)
and t = 9.5 sec is on this line
a = (20 m/s - 30 m/s) / 1 sec = -10 m/s^2
The instantaneous acceleration of the object at time = 9.5 seconds is - 10 m/s².
What is acceleration?Acceleration is the rate at which speed and direction of velocity vary over time. A point or object going straight ahead is accelerated when it accelerates or decelerates. Even if the speed is constant, motion on a circle accelerates because the direction is always shifting.
From t = 9 second to t =10 second the velocity of the object decreases at a constant rate.
Change in velocity of the object = final velocity - initial velocity
= 20 m/s - 30 m/s
= -10 m/s
time interval is = 10 sec - 9 sec = 1 sec.
Hence, acceleration of the object is: a = Change in velocity/ time interval
= - 10 m/s/1s
= -10 m/s²
Therefore, the instantaneous acceleration of the object at time = 9.5 seconds is - 10 m/s².

A 95kg clock initially at rest on a horizontal floor requires a 560N horizontal force to set it in motion. After the clock is in motion, in horizontal force of 650N
Complete Question
A 95 kg clock initially at rest on a horizontal floor requires a 650 N horizontal force to set it in motion. After the clock is in motion, a horizontal force of 560 N keeps it moving with a constant velocity. Find the coefficient of static friction and the coefficient of kinetic friction.
Answer:
The value for static friction is [tex]\mu_s = 0.60[/tex]
The value for static friction is [tex]\mu_k = 0.70[/tex]
Explanation:
From the question we are told that
The mass of the clock is [tex]m = 95 \ kg[/tex]
The first horizontal force is [tex]F _s = 560 \ N[/tex]
The second horizontal force is [tex]F _k = 650 \ N[/tex]
Generally the static frictional force is equal to the first horizontal force
So
[tex]F _s = m * g * \mu_s[/tex]
=> [tex]560 = 95 * 9.8 * \mu_s[/tex]
=> [tex]\mu_s = 0.60[/tex]
Generally the kinetic frictional force is equal to the second horizontal force
So
[tex]F _k = m * g * \mu_k[/tex]
[tex]650 = 95 * 9.8 * \mu_k[/tex]
[tex]\mu_k = 0.70[/tex]

Answer:
100m/s
Explanation:
velocity = displacement/time
The average velocity of the race car around the circular track in the given time is 62.8m/s.
Hence, option D) None of the above is the correct.
What is Average Velocity?Average velocity is simply the displacement of a particle or object over time. It is the rate of change of position of an object with respect to time.
It is expressed as;
Velocity = displacement / time
It can also be expressed as;
Velocity = circumference / time = 2πr / t
Given the data in the question;
Radius of the track r = 500mTime elapsed t = 50sAverage velocity V = ?To determine the average velocity, we substitute our values into the expression above.
V = 2πr / t
V = ( 2 × 3.14 × 500m ) / 50s
V = 3140m / 50s
V = 62.8m/s
The average velocity of the race car around the circular track in the given time is 62.8m/s.
Hence, option D) None of the above is the correct.
