The minimum amplitude of the resultant pulse is 10 cm.
What is amplitude of a pulse?The amplitude of a pulse is the maximum height of the waveform measured from the baseline, also known as the peak-to-peak amplitude. In the case of two pulses, A and B, the minimum amplitude of the resultant pulse is determined by the vector sum of the individual amplitudes of the two pulses.
When two pulses are in phase, the resultant pulse amplitude is the sum of the individual amplitudes, which in this case is 20 cm + 10 cm = 30 cm.
However, if the two pulses are out of phase, the minimum amplitude of the resultant pulse is determined by the difference between the amplitudes of the two pulses. In this case, the minimum amplitude of the resultant pulse would be |20 cm - 10 cm| = 10 cm.
So, the minimum amplitude of the resultant pulse is 10 cm.

What is the role of diffusion in the dialysis process?
A concentration gradient drives the ion-exchange membrane (IEM) separation procedure known as diffusion dialysis (DD).
Diffusion dialysis is referred to be a spontaneous separation technique since the concentration gradient primarily drives the separation process. A membrane separation procedure is DD.
Diffusion is the movement of a solute along a concentration gradient through a membrane. Small molecules are eliminated in this manner during hemodialysate. Diffusion is the net transfer of a substance from a location of high concentration to a region of low concentration, according to physicists and chemists.
Diffusion in hemodialysis is formally defined as the transport of solutes as a result of random molecular motions down its concentration gradient through a semipermeable membrane. Diffusion is how most toxins are removed during dialysis.

After the field is switched off, the object and string eventually return to their original orientation. Once again, it is observed that iron filings and a compass needle are not attracted to the object. The object most likely is exhibiting the property of Diamagnetism.
Diamagnetism is a type of magnetism that is exhibited by all materials, and it is the weakest type. It results in a repulsive force between the material and an external magnetic field. This repulsion is what caused the object to partially align with the magnetic field when it was switched on.
The lack of attraction between the iron filings and the compass needle indicates that the object is not ferromagnetic or paramagnetic, which are both stronger types of magnetism. When the magnetic field was switched off, the repulsive force between the object and the field was no longer present, allowing the object and the string to return to their original orientation.

How does convection cause tectonic plates to move?
A
Convection keeps the plates thin enough to move.
B
Convection makes the plates solid enough to move.
C
The rising heat of convection currents moves the almost-liquid rocks.
D
The pressure of convection bends rocks until they break completely.
The plates become sufficiently stable by convection. The almost liquid rocks are moved by the convection currents' growing heat, hence option C is correct.
What are tectonic plates?Rocks flex under the pressure of convection until they entirely fracture. Radiation decay in the core causes convection currents, which are produced by heat rising and sinking inside the mantle.
In convection currents, the plates are moved. The separation of plates occurs when convection currents split close to the Earth's crust.
Therefore, the convergence of convection currents causes plates to move in the same direction.

4. Driving home from school one day, you spot a ball rolling out in the street. You brake for 1.20 s, slowing your 950 kg car from 16 m/s to 9.5 m/s. a. What was the average force exerted on your car during braking
As stated in the preceding statement When braking, an automobile experiences an average force of 5,145.8 N.
Describe acceleration:An object is considered to have been pushed if its velocity changes. Depending on whether an item is moving faster, slower, or in a new direction, its velocity may change. Examples of acceleration include a falling fruit, the moon orbiting the earth, and an automobile that has stopped at a stop sign.
v = v o + a t ( the acceleration will be negative )
9.50 = 16.0 + a * 1.2
a * 1.2 = -16.0 + 9.50
a * 1.2 = - 6.5
a = - 6.5 : 1.2
a = - 5.4167 m/s²
F = m * a
950 kg * 5.4167 m/s²
F = 5,145.8 N ( the average force exerted on a car during braking )

Four particles with masses 4 kg, 4 kg, 4 kg, and 7 kg are connected by rigid rods of negligible mass as shown. Assume the system rotates in the xy plane about the z axis (origin, O) with an angular speed of 9 rad/s. Find the rotational energy of the system about the x axis.
The rotational Kinetic energy of the system about X axis is 24624 J.
Let the distance of the mass 4kg, from O is r1,
r = √(4² + 4²)
r = √32m
The distances of masses to the rotation axis is same -
say,

Hence,
I = ∑ mi r1²
I = r² ∑(m1 + m + m3 + m4)

A truck with mass of 3,250 kg traveling with a velocity of 25.0 m/s hits a car at rest. After the collision, the truck moves with a velocity of 19.0 m/s. The car has a mass of 2,820 kg. If the two vehicles do not stick together, how fast is the car moving after the collision?
Answer:
6.9 m/s
Explanation:
This is a conservation of momentum problem, so the total momentum before the collision must equal the total momentum after the collision.
P = mv
m1v1 + m2v2 (before) = m1v1 + m2v2 (after)
(3250kg)(25.0 m/s) + (2820 kg)(0m/s) = (3250 kg)(19.0 m/s) + (2820 kg)(v2)
Now you can solve for the v of the car after the collision:
81250 kg·m/s + 0 = 61750 kg·m/s + (2820 kg)v2
19500 kg·m/s = (2820 kg)v2
v2 = 19500 kg·m/s / 2820 kg = 6.9 m/s

Why would a parcel of air rise relative to other air in the atmosphere?
a. A parcel of air will rise if it has a lower density than the surrounding air.
b. A parcel of air will rise if the air in the parcel has a lower mass than the surrounding air.
c. A parcel of air will rise if it has a higher density than the surrounding air.
d. A parcel of air will rise if the air in the parcel has a higher mass than the surrounding air.
A) A parcel of air will rise if it has a lower density than the surrounding air. is the relative order of air in the atmosphere.
In the atmosphere, air moves from high pressure to low pressure areas. When a parcel of air is heated, it expands and becomes less dense than the surrounding air. As a result, the parcel of air rises because it is less dense than the surrounding air, which creates a lower pressure area.
This process is known as convection and is responsible for many weather phenomena such as thunderstorms and cloud formation. In contrast, if a parcel of air cools and becomes more dense, it sinks because it creates a higher pressure area than the surrounding air.

In physics, an object's kinetic energy is the energy it has as a result of its motion. It is defined as the amount of work required to accelerate a body of a given mass from rest to a certain velocity.
The body retains its kinetic energy after gaining it during acceleration until its speed changes. The body does the same amount of work while slowing down from its current pace to rest. Formally, kinetic energy is any term in a system's Lagrangian that contains a time derivative.

A typical spectrophotometer has a path length (the distance light travels through a sample) of 1 cm. Light travels at approximately 3.0 x 108 m/s in vacuum. How long does it take (in ns) for light to travel 1.0 cm
The time taken is 3.33 ns for light to travel 1.0 cm in a spectrophotometer.
What is time?
Time is defined as a scalar quantity that describes the progression of events in the universe. It is often considered to be the fourth dimension of spacetime, along with the three dimensions of space. Time is closely related to the concepts of causality, or the relationship between cause and effect, and is considered to be a fundamental aspect of the physical universe.
The distance light travels in 1 cm is equal to 1 cm x 10^-2 m. To find out how long it takes for light to travel this distance, we can use the formula:
time = distance / speed
Where distance is the distance light travels (1.0 cm x 10^-2 m), and speed is the speed of light in vacuum (3.0 x 108 m/s).
time = (1.0 cm x 10^-2 m) / (3.0 x 108 m/s)
time = 3.33 x 10^-10 s
To convert this time to nanoseconds (ns), we can multiply the time in seconds by 1 billion (10^9):
time = 3.33 x 10^-10 s x 10^9 ns/s
time = 3.33 ns
Therefore, the time taken is approximately 3.33 ns for light to travel 1.0 cm in a spectrophotometer.
