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.

A ball is kicked at an angle of 35° with the ground.a) What should be the initial velocity of the ball so that it hits a target
stiks02 [169]

Answer:

a.18.5 m/s

b.1.98 s

Explanation:

We are given that

\theta=35^{\circ}

a.Let v_0 be the initial velocity of the ball.

Distance,x=30 m

Height,h=1.8 m

v_x=v_0cos\theta=v_0cos35

v_y=v_0sin\theta=v_0sin35

x=v_0cos\theta\times t=v_0cos35\times t

t=\frac{30}{v_0cos35}

h=v_yt-\frac{1}{2}gt^2

Substitute the values

1.8=v_0sin35\frac{30}{v_0cos35}-\frac{1}{2}(9.8)(\frac{30}{v_0cso35})^2

1.8=30tan35-\frac{6574.6}{v^2_0}

\frac{6574.6}{v^2_0}=21-1.8=19.2

v^2_0=\frac{6574.6}{19.2}

v_0=\sqrt{\frac{6574.6}{19.2}}=18.5 m/s

Initial velocity of the ball=18.5 m/s

b.Substitute the value then we get

t=\frac{30}{18.5cos35}

t=1.98 s

Hence, the time for the ball to reach the target=1.98 s

27 degrees to kelvin, 20 dg to milligrams, and 3 to decimeters.
Gala2k [10]
K = C + 273, so 27°C = 27+273 = 300 K

1 dg = 100 mg, so 20 dg = 20×100 = 2,000 mg
