Final answer:

when the velocities of the particles match, their velocity is approximately 49.10 m/s.

Explanation:

For particle 1:

Given x = 9.00t² + 6.00t + 2.00 (in meters and seconds), we can find its velocity by taking the derivative of x with respect to t:

v₁(t) = dx/dt = 18.00t + 6.00

For particle 2:

Given a = -8.00t (in meters per seconds squared and seconds), we can find its velocity by integrating a with respect to t:

v₂(t) = ∫ a dt = -4.00t² + C

Given that at t = 0, v₂(0) = 23.0 m/s, we can solve for C:

v₂(0) = -4.00(0)² + C = C = 23.0

So, v₂(t) = -4.00t² + 23.0

Now, we need to find when their velocities match:

v₁(t) = v₂(t)

18.00t + 6.00 = -4.00t² + 23.0

Now, solve for t:

4.00t² + 18.00t - 17.0 = 0

Using the quadratic formula:

t = (-b ± √(b² - 4ac))/(2a)

Substituting a = 4.00, b = 18.00, and c = -17.0:

t = (-18.00 ± √(324 + 272))/(8.00)

t = (-18.00 ± √596)/(8.00)

t ≈ -1.70 or 2.45

Since time cannot be negative, we discard t = -1.70. Thus, t = 2.45 s.

Now, substitute t = 2.45 s into either v₁(t) or v₂(t) to find the velocity when their velocities match.

Let's use v₁(t):

v₁(2.45) = 18.00(2.45) + 6.00

v₁(2.45) ≈ 49.10 m/s

Final answer:

When the velocities of the particles match, their velocity is 23.0 m/s.

Explanation:

To find the velocity when the velocities of the particles match, we need to set their velocity functions equal to each other. The velocity of particle 1 is obtained by taking the derivative of its position function:

v1(t) = 18.00t + 6.00

The velocity of particle 2 is given to us as 23.0 m/s. So we set:

v1(t) = 18.00t + 6.00 = 23.0

Now, solve the equation for t:

18.00t + 6.00 = 23.0

18.00t = 17.0

t = 17.00/18.00 = 0.94 s

Therefore, when the velocities of the particles match, their velocity is 23.0 m/s.

The required force  to accelerate an object having a mass of 3 kg at 5 m/s² is 15 N.

The definition of force in physics is: The push or pull on a massed object changes its velocity.

An external force is an agent that has the power to alter the resting or moving condition of a body. It has a direction and a magnitude. The application of force is the location at which force is applied, and the direction in which the force is applied is known as the direction of the force.

A spring balance can be used to calculate the Force. The Newton is the SI unit of force.

Given parameters:

Mass of the object: m = 3 kg.

acceleration of the object: a = 5 m/s².

Hence, from Newton's 2nd law of motion:

force = mass × acceleration

= 3 kg × 5 m/s²

= 15 N.

Diffraction or refraction

Answer: C) This is an example of refraction and not diffraction.

Explanation: The reason for the straw to appear bent at the water's surface is because of the process of refraction. Light travels at different speeds in different medium because of the varying densities.

The light travels from air to water and thus the difference in speed results in an apparent shift of the position of part of straw under water and thus the part appears broken.

Reflection is the the return of sound or light energy from the surface without absorbing it.

Diffraction is the phenomenon which occurs when the wave encounters an obstacle.

Time and Distance do not involve direction, as they are scalar quantities. Conversely, Velocity and Acceleration indicate both magnitude and direction, making them vector quantities.

In the context of physics, the terms listed have different implications with regards to direction. Specifically, options A (Time) and C (Distance) do not involve a direction.

Time is a scalar quantity, and it doesn't imply any specific direction. Similarly, Distance is a scalar measurement of the interval between two locations without concerning the direction of travel.

In contrast, both Velocity and Acceleration are vector quantities, meaning they have both magnitude and direction. Velocity is the displacement over time, indicating the rate at which an object changes its position, oriented towards the direction of displacement. Acceleration, on the other hand, depicts the rate of change of velocity, also factoring in the direction in which velocity is changing.

The linear speed of a bicycle wheel with a circumference of 2 meters rotating at 1 revolution per second is 2 meters per second.

The question seeks to find the linear speed of a bicycle wheel given its circumference and rotation rate. The circumference of the bicycle wheel is 2 meters, and it rotates at 1 revolution per second. To calculate the linear speed, we use the relationship that the linear speed (v) is the circumference (C) divided by the period of rotation (T). Since the wheel completes one revolution per second, the period T is 1 second.

Therefore, the linear speed v is given by:

v = C/T

v = 2 meters / 1 second

v = 2 meters per second (m/s).

This calculation shows that if a bicycle wheel with a circumference of 2 meters rotates at 1 revolution per second, its linear speed is 2 m/s.

Silver solder is an alloy with a specific percentage composition that can be graphically represented using a pie chart or bar graph. Alloys combine metals like silver, tin, copper, and zinc to create a material with properties superior to its individual components.

Silver solder is an alloy that consists of multiple metallic components, each with a specific percentage contributing to the total composition. To visually represent the composition of silver solder, one would typically use a pie chart or a bar graph. Given the percentages, we see that silver and tin each make up 40% of the alloy, followed by copper at 14%, and zinc at 6%.

In the making of alloys like silver solder, the individual elements such as tin (Sn) are often produced through processes such as the reduction of tin oxide (SnO₂) with carbon to yield molten tin, which is then drawn off and cast into blocks. The general properties of such elements, including metalloids and their compounds like boron and silicon, are critical to understanding the behavior and uses of the final alloy.

Alloys have properties that differ from those of their constituent metals; for example, they may be harder, more durable, or have better thermal or electrical conductivity. This is why they are often utilized in areas where such enhanced properties are desired.

Final answer:

Silver solder is a mixture of 40 percent silver, 40 percent tin, 14 percent copper, and 6 percent zinc. A graph that shows the composition of silver solder can be drawn using a bar graph or a pie chart.

To make the jump, Neo and Morpheus apply a 'force' to their respective launch points. By Newton's third law, this force results in an equal and opposite reaction force that propels them into the air. The same principle applies to a student jumping from a window, where thrust and mutual gravitational forces come into play.

Explanation:

To make the jump, Neo and Morpheus have pushed against their respective launch points with their legs applying a force to the launch points. When any object wants to jump or launch off the ground, it must exert a force against the ground to propel itself into the air. This concept is described by Newton's third law, which states that for every action, there's an equal and opposite reaction. Therefore, when jumping, our legs push down on the ground, and in response, the ground pushes our bodies upward with an equal force, allowing us to lift off.

This is related to the example of the astronomy student mentioned in the reference material, where the student's and the Earth's mutual forces of gravity result in a change of momentum for both; however, due to Earth's much larger mass, it moves imperceptibly compared to the student. When the student jumps, his acceleration is significantly greater. This can be further explored with the concept of thrust, which is a force that pushes an object forward - in this case, upwards against gravity when the student jumps from the window.

If the total trip took 2.2 secs, then it must took 1.1 secs to reach max height. 

We can then find the max height by realizing that the bag fell from rest and took 1.1 secs to come back to its launch point, we use formula:

hmax  = 1/2 gt^2 = 1/2 (9.8m/s/s)(1.1s)^2 
hmax =5.93m   (ANSWER)

To get the initial speed, we take that the vertical speed is zero at max height, and use 

vf^2=v0^2+2ad 

vf=final speed =0 
v0=intiial speed 
a=acceleration = -9.8m/s/s 
d=distance traveled =hmax= 5.93m 

0=v0^2+2(-9.8ms/s/)(5.93m) 
v0^2=2x9.8x5.93 
v0=10.8m/s  (ANSWER)
