Answer: A solar eclipse occurs when the moon passes in between the Earth and sun, casting a shadow down on the surface of our planet. If you're in the path of the shadow, the moon destroys the sun. No, wait, I mean the moon blocks the sun briefly.A lunar eclipse happens when the moon passes through the Earth's shadow. We see one limb of the moon darken until the entire thing is in shadow.An eclipse does not occur every month, because one month after an eclipse the relative geometry of the Sun, Moon, and Earth has changed. As seen from the Earth, the time it takes for the Moon to return to a node, the draconic month, is less than the time it takes for the Moon to return to the same ecliptic longitude as the Sun.
Explanation:
To find what a is, consider the equation v=at (v=velocity, a=acceleration, t=time interval), making a=v/t. Take the given v of 853m/s, and divide that by your time IN SECONDS, so 1.2ms=1.2*10^-3s.
a=(853)/(1.2*10^-3)=7.11*10^5 m/s^2.
Now Having F=ma, where a is your acceleration, and m=mass (which is 49*10^-3 kg),
F=(49*10^-3)(7.11*10^5)=3.48*10^4 N
Hope this helps!
Answer:
Friction is a kind of force between two object when we rub or slide its surfaces together
for ex: when you rub the matchbox you get fire which is the result of friction
