Answer:
All its mass makes a combined gravitational pull on all the mass in your body.
Explanation:
Basically anything with mass has gravity
Answer:10m/s
Explanation:
Wave speed ,v=for
Where π= wavelength=2m
Period =1/f f=frequency of wave
F=1/period
=1/0.2=5Hz
So speed of waves,v=5×2=10m/s
Solar eclipse: when the sun, moon, and earth align
Lunar eclipse: when the moon blocks the sun's light
1, there is no water there, so plants cant grow
2, there are no plants, hence, there would be no oxygen.
3, (not sure) the temperature is different from earth and could possible not sustain life
Explanation:
a) The Earth makes 1 rotation in 24 hours. In seconds:
24 hr × (3600 s / hr) = 86400 s
b) 1 rotation is 2π radians. So the angular velocity is:
2π rad / 86400 s = 7.27×10⁻⁵ rad/s
c) The earth's linear velocity is the angular velocity times the radius:
40075 km × 7.27×10⁻⁵ rad/s = 2.91 km/s
