Why is it important to keep the muzzle of a firearm pointed in a safe direction, even though the firearm's safety is engaged?

Physics

The correct answer is B. The safety only prevents you from pulling the trigger, but does not stop the pin from striking the primer. For example, if you drop the firearm, the pin may hit the primer and fire the firearm. It is always responsible to keep the firearm pointed in a safe direction so that if this happens, no consequences come out of it.

Answer:

It's probably the Redshift and Blueshift

Explanation:

The light shifting towards shorter or longer wavelengths as objects in space (stars or galaxies) move closer or farther away from us. This phenomenon is known as the Redshifts and Blueshifts. The concept indicates us that the Universe is expanding.

Hope this helps you!

The definition of speed is (distance covered) / (time to cover the distance) .

So a unit of speed has to be (a unit of length) / (a unit of time) .

Here are several perfectly fine units of speed:

-- miles per hour

-- feet per second

-- meters per second

-- kilometers per hour

-- inches per second

-- centimeters per minute

-- yards per Century

-- furlongs per fortnight

-- nanometers per microsecond

-- Smoots per week

-- parsecs per millenium

We think of the response of the circuit as the ratio of the maximum current to the maximum voltage provided. Explain why the rat
nexus9112 [7]

Answer:

Z = R, i = V/Z,    w = √1 / LC

Explanation:

In an RLC circuit the impedance of the circuit is

          Z = √[R² + (X_{L} - X_{C})²

Where

      X_{L} = wL

      X_{L} = 1 / wC

They are the reactances of the inductor and the capacitor, in this case the current advances to the voltage in the first and is delayed from the voltage in the second, so when the two values ​​give the same reactance the current goes in phase with the voltage and the impedance is minimal

          Z = R

          V= i Z

           i = V/Z

Therefore the current is maximum, this occurs when

       w = √1 / LC

Saying that this is the resonant frequency
