If your engine is flooded with gasoline, you should push the brake, to the floor and hold for 5 seconds.
What is gasoline?Gasoline or petrol is a transparent, petroleum-derived flammable liquid that is used primarily as a fuel in most spark-ignited internal combustion engines. Gasoline is already considered frozen if it turns into a thick sludge or wax. To totally avoid frozen gasoline inside the car, focus on preventing the fuel line from freezing during winter. Stale gasoline can be dangerous as it contains a combination of over 150 chemicals that can destroy both animal and human lives. Gasoline vapors are heavier than air, so they settle on the ground and travel like a liquid. Because of this, they often find their way into drains, basements, and sewer lines.

B. The horizontal distance the frisbee will go is 29.4 m
A. How to determine the time the frisbee will remain in the airThe time the frisbee will spend in the air can be obtained as illustrated below:
Height (h) = 169.2 mAcceleration due to gravity (g) = 9.8 m/s²Time (t) =?169.2 = ½gt²
169.2 = ½ × 9.8 × t²
169.2 = 4.9 × t²
Divide both side by 4.9
t² = 169.2 / 4.9
Take the square root of both side
t = √(169.2 / 4.9)

On hoods where sashes open vertically, work with the hood sash in the lowest position.
What Is A Sash On A Fume Hood?In the event of a fire, the fume hood sash offers a containment space. It functions as a blast barrier. The sash itself, together with the bypass grill above the sash, controls the fume hood's airflow properties. The sash's position does regulate the air velocity traveling through the fume hood, even if it has no effect on the amount of air passing through the fume hood. Air velocity is another element that affects chemical vapor capture. Raising the sash reduces the capture velocity, allowing vapors to start flowing over the sill and into the room's air.

What is electric force?Electric force is the force of attraction between two charged particles.
The magnitude of the electric force is given by F = kq₁q₂/r² where
k = electrostatic constant, q₁ = charge on particle one, q₂ = charge on particle two and r = distance of separation between the two charges.Given that we have two charged particles q₁ and q₂ separated by a distance r, the electric force betwen them is given by F = kq₁q₂/r²
Now, if we want to increase the force by a factor 16, we have the new force F' = 16F
F' = 16kq₁q₂/r²
F' = k16q₁q₂/r²
F = k(16q₁)q₂/r² or kq₁(16q₂)/r²

The coupling constant (j) for bromoethane is 7 hz when the 1h nmr spectrum is acquired at 250 mhz. what is the coupling constant between these protons when the spectrum is acquired at 500 mhz?
The coupling constant between these protons when the spectrum is acquired at 500 MHz is 7Hz.
Coupling Constant:
The coupling constant of a molecule changes when the molecular structure of the component varies. Thus the coupling constant of a particle doesn't depend on the strength of the field and other factors.
Given that,
The coupling constant of bromoethane when the spectrum acquired is
J=7Hz.
The frequency acquired for the coupling constant is f=250MHz
The coupling constant of a molecule is independent of the resolution thus if the resolution of the molecule is either 250 MHz or 500 MHz or any other value the coupling constant remains the same. It only varies when the molecular structure of the element changes.
Therefore,
Thus the coupling constant of Bromoethane at 500 MHz is 7Hz.

What is voltage polarity?All voltages and currents possess both magnitude and polarity. One current flows through the entirety of a series circuit with its polarity flowing from the negative battery terminal to the positive battery terminal. Polarities are also seen in voltage dips across loads. Utilizing the electron current's direction as a starting point is the simplest method for determining these polarities. The voltage is then negative where the electron current enters the load (Figure 31). No matter how many or what kind of loads are present in the circuit, this remains true. The potential drop is opposite of the source across the load. In opposition to the source voltage, the voltage dips lower it for the other loads.
