In other words, it means give an example of something in your life that you rely on to keep you safe.

Example: "I rely on my car's testing and evaluation of it's product design to keep me safe from getting into an accident or it breaking down."

NeX [460]

Answer:

The power of the bulb is reduced to a quarter

Explanation:

The power in an electrical circuit is

         P = V I = I² R

If the dimmer cuts the current in half

        I = I₀ / 2

The resistance of the light bulb after hot is little affected by small changes in the current

We substitute in the equation

       P = I₂ R

       P = (I₀ /2)² R

      P = ¼ I₀² R

      P = ¼ P₀

The power of the bulb is reduced to a quarter

Bats can detect small objects such as insects that are of a size on the order of a wavelength. if bats emit a chirp at a frequen
crimeas [40]
The smallest size of the insect that the bats can detect corresponds to the wavelength of the chirp they emit.

Their chirp has a frequency of
f=69.3 kHz=69.3 \cdot 10^3 Hz
and the speed of the chirp is equal to the speed of sound in air:
v=330 m/s
Therefore the wavelength of the chirp is
\lambda= \frac{v}{f}= \frac{330 m/s}{69.3 \cdot 10^3 Hz}=4.76 \cdot 10^{-3} m
which corresponds to a size of 4.76 mm.
