Explain why Earth does not have as many craters as Mars, Mercury, and the Moon.

Physics
1 answer:
Lilit [14]3 years ago
3 0

Answer:

The reason is mainly because Earth  has an atmosphere.

Explanation:

We don't see as many craters in our planet as most of them have been eroded away by wind, water, volcanic activity or any other forces. Earth is also surrounded by an atmosphere which other planets like Mars, Mercury and the Moon lacks. The atmosphere reduces the impact of meteoroids when they hit the surface of a planet as the atmosphere disintegrates them into smaller particles. Also, the atmosphere creates a planet's own weather condition, no atmosphere means no weather. So, planets like Mars, Mercury where there is no atmosphere, there is no weather to erode away the craters. Hence, most of them are still visible on their surfaces.

Hello!
Mnenie [13.5K]

Answer:

T_0=80695.17162...

Explanation:

Given equation:

\ln \left(\dfrac{T_0-100}{T_0}\right)=-0.00124

To solve the given equation:

\textsf{Apply log rules}: \quad e^{\ln (x)}=x

\implies \dfrac{T_0-100}{T_0}=e^{-0.00124}

Multiply both sides by T₀:

\implies T_0-100=T_0e^{-0.00124}

Add 100 to both sides:

\implies T_0=T_0e^{-0.00124}+100

Subtract T_0e^{-0.00124} from both sides:

\implies T_0-T_0e^{-0.00124}=100

Factor out the common term T₀:

\implies T_0(1-e^{-0.00124})=100

Divide both sides by (1-e^{-0.00124})

\implies T_0=\dfrac{100}{1-e^{-0.00124}}

Carry out the calculation:

\implies T_0=\dfrac{100}{1-0.99876...}

\implies T_0=\dfrac{100}{0.001239231...}

\implies T_0=80695.17162...

Find the value of 15.0 N in pounds. Use the conversions 1slug=14.59kg and 1ft=0.3048m. Express your answer in pounds to three si
kotykmax [81]

Given the equivalent value to convert the units from kilograms to slug and feet to meters, we will proceed to define the equivalence of the 'Newton' in simplified units, that is,

1N=1kg\cdot m\cdot s^{-2}

Then,

15.0N=15.0kg\cdot m\cdot s^{-2}

Converting this value to British units we have that

15N = 15.0kg\cdot m\cdot s^{-2} (\frac{1slug}{14.59kg})(\frac{1ft}{0.3048m})

15N = 3.37 slug \cdot ft \cdot s^{-2} (\frac{1 lb \cdot ft^{-1}}{1slug})

15N =3.37lb

Therefore the value of 15.0 N in pounds is 3.37 lb.
