A. Quartz is harder than chalk.
B. Water has a higher surface tension than salty water.
Explanation:
did the test !
The two statements about the substances in the experiment are true are
Quartz is harder than chalk and the Water has a higher surface tension than salty water. Therefore the correct options are option A and option B.
What is the matter?Anything which has mass and occupies spaces is known as matter, mainly there are four states of matter solid liquid gases, and plasma.
These different states of matter have different characteristics according to which they vary their volume and shape.
The hardness of quartz is more than that of chalk.
The surface tension is because of the cohesive force of the molecules among them, surface tension can be defined as force per unit length and represented in the unit N/s.
The cohesive force of attraction is more in water as compared to that of salty water therefore the surface tension of the water is more than that of salty water.

[tex] \underline{ \bf{\underline{\large{Terminal \: Velocity}}}}[/tex]
The maximum constant velocity acquired by a body while falling through a viscous medium is called it's terminal velocity. It is usually denoted by [tex] \sf V_T [/tex].It is directly proportional to the square of the radius of the body (a²) & the difference of the densities of the body and the fluid [tex] \sf (\rho - \sigma) [/tex].It is inversely proportional to the viscosity of the medium [tex] \sf (\eta) [/tex].Formula of Terminal Velocity:[tex] \boxed{ \bf{V_T = \dfrac{2}{9} \dfrac{ {a}^{2} }{ \eta} ( \rho - \sigma)g}}[/tex]if a truck hits a bug, they exert the exact same force on each other. That force is strong enough to squish the bug, but not strong enough to damage the truck. The force makes the bug accelerate very rapidly, but the truck keeps moving at a constant velocity.

Which temperature is the hottest? 98 F or 39 C or 303K?
F= 1.8C + 32
C= (F-32)/1.8
Answers
Answer:
The hottest temperature is [tex]T_2 = 39^o C[/tex]
Explanation:
From the question we are given
[tex]T_1 = 98 F[/tex]
[tex]T_2 = 39^oC[/tex]
[tex]T_3 = 303 \ K[/tex]
Generally converting [tex]T_3[/tex] to Fahrenheit
[tex]T_3' = (T_3 -273 ) * \frac{9}{5} + 32[/tex]
=> [tex]T_3' = (303 -273 ) * \frac{9}{5} + 32[/tex]
=> [tex]T_3' = 86 F[/tex]
Converting [tex]T_2[/tex] to Fahrenheit
[tex]T_2' = T_2 * \frac{9}{5} + 32[/tex]
=> [tex]T_2' = 39 * \frac{9}{5} + 32[/tex]
=> [tex]T_2' =102.2 F[/tex]
Now comparing the temperature in Fahrenheit we see that [tex]T_2[/tex] is the hottest

C. New cells are created but quickly die during cell growth.
D. Humans are born with all the cells they will ever need.
Answers
Answer:
B. New cells are created from pre-existing cells in the human body.
Explanation:
According to the cell theory, the correct assumption from the student's investigation is that "new cells are created from pre-existing cells in the human body".
One of the postulates of the cell theory is that all cells originated from pre-existing cells. Also, a cell is the fundamental unit of life.So, the student is correct to say that new cells are created from pre-existing cells in the human body.

Which label part represents the wavelength
Answers
Answer:
Q
Explanation:
To know which symbol defines the wavelength, we must know the definition of wavelength.
Wavelength can be defined as the distance between two successive crests (i.e the highest part) or troughs (the lowest part) of a wave.
Considering the diagram given above, Q shows the distance between two successive crests (i.e the highest part) of the wave. Therefore, Q is the wavelength of the wave given in the diagram above.

A ball is thrown upward with a speed of 40 m/s. Approximately how much time does it take the ball to travel from the release location (A). Till its highest point (B)? Approximately how much total time is the ball in the air before it returns back to its original height (C)?
Answers
I'm going to assume that this gripping drama takes place on planet Earth, where the acceleration of gravity is 9.8 m/s². The solutions would be completely different if the same scenario were to play out in other places.
A ball is thrown upward with a speed of 40 m/s. Gravity decreases its upward speed (increases its downward speed) by 9.8 m/s every second.
So, the ball reaches its highest point after (40 m/s)/(9.8 m/s²) = 4.08 seconds. At that point, it runs out of upward gas, and begins falling.
Just like so many other aspects of life, the downward fall is an exact "mirror image" of the upward trip. After another 4.08 seconds, the ball has returned to the height of the hand which flung it. In total, the ball is in the air for 8.16 seconds up and down.
HELP ME PLEASE
I don’t know what the answer is.
Answers
Answer:
Hey buddy, here is your answer. Hope it helps you.
Explanation:
Solids.Sound travels fastest through solids. This is because molecules in a solid are packed against each other. When a vibration begins, the molecules of a solid immediately collide and the compression wave travels rapidly.Sound moves slowest through a gas. That’s because the molecules in a gas are spaced very far apart. In order for sound to travel through air, the floating molecules of matter must vibrate and collide to form compression waves. Because the molecules of matter in a gas are spaced far apart, sound moves slowest through a gas.
Sound travels faster in liquids than in gases because molecules are packed more closely together. This means that when the water molecules begin to vibrate, they quickly begin to collide with each other forming a rapidly moving compression wave.

How do the individual forces compare when the rider experiences a normal
sensation of weight? What is the acceleration value when this occurs?
Answers
Answer:
The rider experiences weight or does not experience weight depends upon the direction of the elevator in which it moves and its acceleration.
Explanation:
Consider the mass of a rider as m. So its actual weight is mg and it acts vertically downward. The apparent weight of the rider is depended on the acceleration of the elevator and its direction of movement.
When elevator moves with a constant speed i.e. its acceleration is zero, the apparent weight of the rider is equal to the actual weight. Thus the rider's sensation is normal.
If the elevator is moving upward with an acceleration a, then the apparent weight of the rider will be more and the rider will experience an increase in weight or the sensation is heavy.
Or when the elevator moves downward with an acceleration a, the apparent weight of the rider is less. And the rider sensation is lighter.
The acceleration will become "0 (zero)". A further solution to the question is provided below.
Individual pressures neutralize or negate each other out if somehow the riding experiences stable weight, implying that perhaps the rider's cumulative acceleration will be zero,Now,
→ [tex]mg= W+F[/tex]
or,
→ [tex]g= a+g[/tex]
then,
→ [tex]a =0[/tex]
This means that the rider isn't moving. Thus the response above is appropriate.

Calculate the acceleration in meters per second-squared, of a car moving at 10 m/s that accelerates to 24 m/s over a time of 7 second--
Answers
Explanation:
v = u + at
24 = 10 + a * 7
24 = 10 * 7 a
a = 24 - 10/7
a = 14/7
a = 2m/sec^2
hope it helps you
Answer:
First calculate change in velocity:
final velocity = 20 m/s.
initial velocity = 30 m/s.
change in velocity = (20 - 30) = -10 m/s.
acceleration = -10 ÷ 25.
acceleration = -0.4 m/s 2
The acceleration value is negative here because the car is slowing down or decelerating.

Can frictional forces ever increase an object’s kinetic energy?
Answers
Explanation:
friction opposes the relative motion between two bodies,hence it decreases the kinetic energy but, in the view that friction supplies the force that accelerates the object , for example friction helps in walking we can say that friction causes an increase in kinetic energy
Answer:
In most situations, frictional forces tend to reduce the kinetic energy of an object. However, frictional forces can sometimes increase an object's kinetic energy.
