Answer:
g = 0.85 m![s^{-2}](https://tex.z-dn.net/?f=s%5E%7B-2%7D)
Explanation:
g = ![\frac{GM}{h^{2} }](https://tex.z-dn.net/?f=%5Cfrac%7BGM%7D%7Bh%5E%7B2%7D%20%7D)
were; g is the acceleration due to Earth's gravity, G is Newton's gravitation constant (6.674 x
N![m^{2}](https://tex.z-dn.net/?f=m%5E%7B2%7D)
), M is the mass of the earth (5.972 x
kg), and h is the distance of meteoroid to the earth.
h = 3.40 x R
= 3.40 x 6371 km
h = 21661.4 km
= 21661400 m
Thus,
g = ![\frac{6.674*10^{-11}*5.972*10^{24} }{(21661400)^{2} }](https://tex.z-dn.net/?f=%5Cfrac%7B6.674%2A10%5E%7B-11%7D%2A5.972%2A10%5E%7B24%7D%20%20%7D%7B%2821661400%29%5E%7B2%7D%20%7D)
= ![\frac{3.9857 *10^{14} }{4.6922*10^{14} }](https://tex.z-dn.net/?f=%5Cfrac%7B3.9857%20%2A10%5E%7B14%7D%20%7D%7B4.6922%2A10%5E%7B14%7D%20%7D)
= 0.84944
g = 0.85 m![s^{-2}](https://tex.z-dn.net/?f=s%5E%7B-2%7D)
The acceleration due to the Earth's gravitation is 0.85 m

Answer:
its all black I cant see the image can you re upload it
Explanation:
The final magnification will be 400-fold or 400 times the original size of the object.
For magnifying smaller objects, a compound microscope is used.
A compound microscope consists of an objective and an eyepiece, whose diagram is shown in the adjoining image.
The lens near the object is called an objective and the other one is the eyepiece.
Let the magnification of the objective be m1
Let the magnification of the eyepiece be m2
The final magnification by the microscope, M, will be
M = m1 x m2
Putting the values in the above equation
M = 40 x 10
M= 400
Thus, the final magnification will be 400-fold or 400 times the original size of the object.

Answer:
PHYSICS - Physics is the natural science that studies matter, its motion and behavior through space and time, and the related entities of energy and force. Physics is one of the most fundamental scientific disciplines, and its main goal is to understand how the universe behaves.
<u>SCIENCE -</u> Science is a systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the universe. The earliest roots of science can be traced to Ancient Egypt and Mesopotamia in around 3000 to 1200 BCE.
This is all I got, but if you want to know more or need more, i’m sure there are websites that have more info.
