Which part of the following excerpt from an after-action report is inappropriate to include?
Our goal was to make the Fierce Dragon a more exciting and desirable toy for older children. To meet this goal, we chose to increase the number of working parts and to make the face appear angrier. Even though there were several disputes during our meetings, a 25-percent increase of sales in the target age group over the past three months indicates we met our goal. The initial response to the redesigned toy was very positive; however, the number of returns due to a broken jaw joint indicates more testing of the design should have been done.

The velocity of the vehicle is equal to 406.5 m/s. The velocity in Km/hr is 1463.4 Km/hr.
What is the velocity?Velocity can be demonstrated as a vector measurement of the direction of the object and the rate of motion of an object. The velocity of an object can be described as the change in the body's position w.r.t. time.
Velocity can be expressed as a vector quantity as it consists of magnitude as well as direction. A mathematical formula common and simplest way to find velocity.
v = d / t
Where v is the velocity, d is the distance covered and t is the time taken by the body.
The S.I. unit for velocity can be represented as m/s and can be expressed in terms of miles per hour (mph), and kilometers per hour (kph).
Given, the distance traveled by the vehicle, d = 100 m
The time taken by vehicle = 0.246 sec
The velocity of the vehicle, v = 100/0.246 = 406.5 m/s
We know that 1km = 1000m then 1 m = 10⁻³ Km
1 hour = 60 ×60 = 3600 s
1s = 1/3600 hr
Therefore, velocity, \(\displaystyle v = 406.5 \times \frac{3600}{1000} Km/hr\)
v = 1463.4 Km/hr
Learn more about velocity, here:
brainly.com/question/19979064
#SPJ2
Velocity = Distance / Time = 100 m / 0.246 s = 406.50 m/s
To convert m/s to km/hr, we need to multiply the velocity by 3.6:
Velocity in km/hr = Velocity in m/s x 3.6 = 406.50 m/s x 3.6 = 1463.80 km/hr
The steps I took to convert from m/s to km/hr were to multiply the velocity in m/s by 3.6, which is the conversion factor between meters per second and kilometers per hour.

Students have a small steel ball and a large steel ball, and they have a short ramp and a tall ramp.
The students want to find out if a ball's size affects how far it can roll. They also want to find out if the height of the ramp affects how far the ball can roll.
They do the following experiment: (second image)
The students finish conducting their tests and conclude that using a taller ramp and a larger ball will make the ball roll further. Is their conclusion based on a reliable experiment?
A.Yes, because they used the same color balls.
B.No. They did not do an additional test to compare the results using the short ramp.
C.No. The small ball should have been pushed with more force.

Why does the coil keep spinning?
Which way is electricity flowing?
Answers
Answer:
The coil keeps spinning because of the interaction between the magnetic field generated by the flow of electricity in the coil and the magnetic field of the permanent magnet surrounding it. This interaction creates a force that causes the coil to rotate continuously.
As for the direction of the electricity flow, it depends on the design of the coil and the direction of the magnetic field. If the coil is connected to a direct current (DC) source, the electricity will flow in a single direction. If the coil is connected to an alternating current (AC) source, the direction of the electricity flow will change periodically, typically many times per second.
In general, the direction of the electricity flow can be determined using Faraday's law of electromagnetic induction, which states that a changing magnetic field will induce an electromotive force (EMF) in a conductor, which will cause electricity to flow in the conductor. The direction of the induced EMF and the resulting electricity flow will depend on the direction of the changing magnetic field and the direction of the coil.
Explanation:
Answer:
The inertia of the rotating coil carries it through half of a turn, past the insulating paint. When the electric current starts to flow again, the twisting force is in the same direction as it was before. The coil continues to rotate in the same direction.
The permanent magnets exert forces on the electrical currents flowing through the loop of wire.

\(2.613\:\cdot10^5\) Joules ; 5. Adding the same amount of heat to two different objects will produce the same increase in temperature ; 2. Same speed in both ; 2. A
Explanation:
Diagram 1 ( Liquid Nitrogen ) : So as you can see, we want our units in Joules here, and can therefore multiply the mass of gaseous nitrogen and the latent heat of liquid nitrogen, to cancel the units kg, and receive our solution - in terms of Joules. Let's do it.
q ( energy removed ) = mass of nitrogen \(*\) latent heat of liquid nitrogen,
q = 1.3 kg \(*\) 2.01 \(*\) 10⁵ J / kg = \(1.3\:\cdot \:2.01\:\cdot \:\:10^5\) = \(10^5\cdot \:2.613\) = \(100000\cdot \:2.613\) = \(261300\) Joules = \(261.3\) kiloJoules = 2.613 \(*\) 10⁵Joules is the energy that must be removed
Diagram 2 : The same amount of heat does not necessarily mean the same increase in temperature for two different objects. The increase in temperature depends on the specific heat capacity of the substance. Therefore your solution is 5 ) Adding the same amount of heat to two different objects will produce the same increase in temperature.
Diagram 3 : The temperatures in both glasses are the same, and hence the molecules have the same average speed. Therefore your solution is 2 ) Same speed in both.
Diagram 4 : Glass A has more water molecules, and hence has more thermal energy. Your solution is 2 ) A.
