Acceleration due to gravity on the moon is 1.6 m/s^2 or about 16% of the value of g on Earth. If an astronaut on the moon threw

a moon rock to a height of 7.8 m, what would be its velocity as it struck the moon’s surface? How would the fact that the moon has no atmosphere affect the velocity of the falling moon rock?

Answer:

b.) the diverge in incident beam of light

Explanation:

A lens refers to any refracting surface. The manner in which a lens is curved tells whether it is a concave(diverging) lens or a convex (converging) lens.

A convex lens is thicker at the center than at the edges. It makes light to converge at a point.

A concave lens is is thinner at the center than at the edges. It makes light to appear to diverge from a point, hence the answer above.

There is evidence that elephants communicate via infrasound, generating rumbling vocalizations as low as 14 Hz that can travel u
amid [387]

Answer:

L = 96.2 dB

Explanation:

As we know that the level of intensity is given as

\beta = 10Log(\frac{I}{I_o})

here we know

\beta = 104 dB

104 = 10Log(\frac{I}{10^{-12}})

I = 0.025 W/m^2

now the sound is travelling in all possible directions so we have

\frac{I_1}{I_2} = \frac{r_2^2}{r_1^2}

\frac{0.025}{I_2} = \frac{10^2}{4.1^2}

I_2 = 4.2 \times 10^{-3} W/m^2

now for level of sound we have

L = 10Log(\frac{4.2 \times 10^{-3}}{10^{-12}})

L = 96.2 dB

Write the equation that links current, potential difference, and resistance
mrs_skeptik [129]

You can write the equation in 3 different ways, depending on which quantity you want to be the dependent variable.  Any one of the three forms can be derived from either of the other two with a simple algebra operation.  They're all the same relationship, described by "Ohm's Law".

==> Current = (potential difference) / (resistance)

==> Potential difference = (current) x (resistance)

==> Resistance = (potential difference) / (resistance)
