The term "deflagration to detonation transition" (DDT) describes a phenomenon that occurs in combustible gas and air (or oxygen) combinations when a quick change occurs from a deflagration type of combustion to a detonation type of explosion.
The general process by which a subsonic combustion wave (deflagration or flame) transforms into a supersonic combustion wave is known as the deflagration-to-detonation transition (detonation). Explosives are chemicals that contain a sufficient amount of oxygen within their molecules. When they are started, they could detonate disastrously or burn furiously, sending shock waves (detonate). Primary explosives are those high explosives that are extremely sensitive to heat, shock, or friction and are the main component of blasting caps or primers that set off other explosives.

Two rocket ships approach a space station at 80% of the speed of light. Each pilot observes the other ship approaching at 98% the speed of light.
What is the "Fastest" Speed of Light?Light moves at a constant, finite speed of 186,000 miles per second. A traveler traveling at the speed of light would circumnavigate the globe 7.5 times in one second. In comparison, a traveler in a jet aircraft traveling at 500 mph would cross the continental United States once in 4 hours.The speed of light in a vacuum, denoted c, is a universal physical constant that is important in many fields of physics. The speed of light c equals 299,792,458 meters per second.The speed of light is shared by all forms of electromagnetic radiation, including visible light. Light and other electromagnetic waves appear to propagate instantly for many practical purposes, but their finite speed has noticeable effects over long distances and with very sensitive measurements. Starlight seen from Earth long ago left the stars, allowing humans to study the history of the universe by viewing distant objects.

At a certain temperature, the phph of a neutral solution is 7.68. what is the value of kwkwk_w at that temperature?
Kw = 4.36×10^-16 is the value of kw at temperature when the ph of a neutral solution is 7.68.
The formula for Kw is:
Kw= [H]*[OH]
where [H] and [OH] are concentrations
We are given the pH so we can calculate the [H] concentration from the formula:
pH=-log[H]
[tex]P_{H} =-log_{10} [H^{+} (aq)][/tex]
[tex]-P_{H} =log_{10} [H^{+} (aq)][/tex]
[tex][H^{+} (aq)]=10^{-P_{H} }[/tex]
[tex][H^{+} (aq)]=10^{-7.68}[/tex]
[tex][H^{+}(aq) ]=[/tex]2.089×[tex]10^{-8}[/tex]mol [tex]dm^{-3}[/tex]
In neutral solution, [H] = [OH],
therefore: [OH]=2.089×10^-8M
Calculating Kw:
Kw = (2.089×10^-8M) *(2.089×10^-8M)
Kw = 4.36×10^-16

3.if kiis 44 nm for (-)d9-thc and 4350 nm for cbd what is the binding free energy difference, in kj/mol?
The correct answer is 0.00981 kJ/mol.
Every object we encounter has a binding force, and the energy that holds them together is the binding energy. The binding energy is the least amount of energy necessary to remove an electron, proton, or neutron from the nucleus. A nucleus contains electrons and protons that are strongly bound by energy.
Free energy of binding can be calculated using formula, Gbinding = dE coluombic + dEvdw + dGhyd. -TdS where Evdw+Ecoulombic is protein ligand interaction, dGhyd is change in hydration energy.
dS is entropy. dG hydration is Gpolar+Gnon polar. Inhibition constants are given for CBD and
THC = 4350nm, and 44nM. So,
dG = Ki + Ki' = 44+4350 = 4394 and

if you are driving 120 km/h along a straight road and you look to the side for 2.2 s , how far do you travel during this inattentive period?
During this inattentive period, the distance traveled is 73.33 when the speed is 120 km/h and the time taken is 2.2 s.
What connection exists between time, distance, and speed?Every moving object travels a particular distance over time. These two factors enable us to determine the speed. The frequency of displacement is the sole determinant of speed. The complete mobility of an object, regardless of direction, will be its distance. No matter where an object originates or finishes, distance measures how much ground it has travelled. A process, an action, or a condition's duration is the amount of time that can be measured or quantified. Speed is the rate at which an object travels along a path over time, whereas velocity is the speed and direction of an item's motion. In another sense, velocity is a vector, whereas speed is a scalar value. There is a formula that connects these three things. Speed can be thought of as a gauge for a body's rate of motion. The distance covered in a single unit of time is how it is defined.
Speed = Distance/ Time
We are given Average speed, = 120 km/h=(120 * 1000)/3600=33.33 m/s
Time, t=2.2s
Now speed = Distance/ Time

Given that vector a b = c, and that lal lbl = lcl, how are vectors a and b oriented with respect to each other?
Vector a b = c, and that |al |b| = |cl, vectors a and b oriented with respect to each other because they are perpendicular to each other.
What is a vector?A vector is an object that has both magnitude and a direction. Geometrically, we can picture vector as a directed line segment, whose length is the magnitude of the vector and with an arrow indicating the direction. The direction of vector is from its tail to its head.
Two vectors are the same if they have same magnitude and direction. This means that if we take a vector and translate it to a new position (without rotating it), then vector we obtain at the end of this process is the same vector we had in beginning.
Two examples of vectors are those that represent the force and velocity. Both the force and velocity are in a particular direction. The magnitude of vector would indicate the strength of the force or the speed associated with the velocity.
We denote vectors using the boldface as in a or b. Especially when writing by hand where one cannot easily write in boldface, people will sometimes denote vectors using the arrows , or they use the other markings. We won't need to use the arrows here. We denote magnitude of the vector a by |a|. When we want to refer to a number and stress that it is not a vector, we can call number a scalar.

This amount is voltage for capacitors and current for inductors. This amount is to be used as the "beginning" value because when the switch in a circuit is closed (or opened), the reactive component will try to keep that quantity at the same level as it was before the switch transition.

Write a differential equation for the concentration of the chemical in the pond at time t. hint: the concentration is c = a/v = a(t)/106
The differential equation for the concentration of the chemical is given by dc/dt = (3/10⁶)(1 - 100c)
Suppose that a(t) is the amount of chemical in the pond at time t.
So, a'(t) = rate of chemical inflow - the rate of chemical outflow.
So, da/dt = (0.01)300 - (a/10⁶)300
So, da/dt = 3 - 3a/10⁴
Now,
Since, c = a/v
Then, c' = a'/v
So, c' = (3 - 3a/10⁴)/10⁶
Or, c' = 3 (1 - a/10⁴)/10⁶
So, dc/dt = 3/10⁶ (1 - cv/10⁴)
So, dc/dt = (3/10⁶) (1 - 100c)
Therefore the differential equation for the concentration of the chemical is dc/dt = (3/10⁶)(1 - 100c)

the home owner report that sometimes the electric furnace trip the 240-v 60-a circuit breaker connected to it
The homeowner has reported that sometimes the electric furnace trips the 240-V, 60-A circuit breaker connected to it. Upon examination, it is found that the furnace contains three 5000-W heating elements designed to turn on in stages.
SolutionThe power rating of the circuit breaker = volt x current
= 240 x 60
= 14400 W
So, we have 3 units of 5000W each.
Explanation and RecommendationWhen the first unit is turned on, the consumption is 5000W and the circuit breaker does not trip. When two of the 5000W units are turned on, it adds up to a consumption of 10000W.
The circuit breaker is still intact. But when the 3rd 5000W unit is turned on, the consumption reached to 15,000W which is greater than the 14,400W mark, and thus the circuit breaker trips off.
So, switching on all three units at once can cause the circuit breaker to trip off.
So, the recommendation would be that at a particular time maximum of two units can be turned on.
Even such, the two units cannot be turned on in series or they won’t receive 240 V each.
Another recommendation would be to use a circuit breaker of a higher power rating, more than 15,000W so that there will be no tripping.
