<h2>Answers:</h2>
<u>The possible effects on the earth will be</u><u> 1) No light during night 2) No tides</u>
<h2>Explanation:</h2>
As we know that tides are caused by the differential gravitational force on the equatorial regions by the moon. So if the Moon escapes from Earth, the main effect would be the lack of tides on Earth The region closer to the Moon experiences more gravitational force than the region on Earth away from the Moon. Other effects will be no more Moon to light up the night sky and no more solar eclipses.
Answer:
Explanation:
An object is thrown up from a height of 520m
h_o = 520m
Initial velocity of thrown is 18m/s
u = 18m/s
What is the position of the object after 3seconds
t = 3s
Acceleration due to gravity
g = 9.81 m/s²
Let calculated the height the object will reached when thrown from the top.
Using equation of motion
h = ut + ½gt²
Since the body is thrown upward, it is acting against gravity then, gravity will be negative
Then,
h = ut — ½gt²
h = 18 × 3 — ½ × 9.81 × 3²
h = 54 — 44.145
h = 9.855 m
So, the body is above the top of the building at a distance of 9.855m
So, the total distance from the bottom is
Position = h + h_o
x = 9.855 + 520
x = 529.855m
x ≈ 530m,
The position of objects after 3seconds is 520m
