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.
Answer:
D. A low lambda, λ, and a high nu, ν
Explanation:
- Both x-rays and radio waves are electromagnetic waves that are part of the electromagnetic spectrum.
- <em><u>Radio waves have the longest wavelengths in the electromagnetic spectrum and the lowest frequency.</u></em>
- X-rays on the other hand <em><u>have a higher frequency compared to radio waves and a lower wavelength than that of the radio waves</u></em>.
- All electromagnetic waves in the electromagnetic waves travel with a speed of light, 3.0 × 10^8 m/s. They also posses energy given by the formula E = hf, where h is the plank's constant.
A horseshoe magnet has north and south, so does a bar magnet, but with the horseshoe magnet, the whole thing is bent so both ends are the same way. <span />
