Answer:
As the earth is an oblate spheroid, its radius near the equator is more than its radius near poles. Since for a source mass, the acceleration due to gravity is inversely proportional to the square of the radius of the earth, it varies with latitude due to the shape of the earth.
Formula: g = GM/r2
Dimensional Formula: M0L1T-2
Values of g in SI: 9.806 ms-2
Explanation:
Please Mark me brainliest
Given: Mass m = 60 Kg
Weight W = 96 N
Required: Acceleration due to gravity, g = ?
Formula: W = mg
g = W/g
g = 96 Kg.m/s²/60 Kg (note: this is the derive unit for Newton "N")
g = 1.6 m/s²
Answer:
The Height is H = 70.02 m
Explanation:
We are given that the
Initial length is =
= 
from what we are told in the question the circumference of the circle is =
This means that the Radius would be :
Let C denote the circumference
So

=> 

We are told that 1-meter bar of steel that increases its temperature by 1 degree C will expand
meters
Hence
The final length would be

Where T is the change in temperature
is the Coefficient of linear expansion for steel
let
denote the final length
So
![L_{final} =40000*10^{6} *[1+ 11*10^{-6}]](https://tex.z-dn.net/?f=L_%7Bfinal%7D%20%3D40000%2A10%5E%7B6%7D%20%2A%5B1%2B%2011%2A10%5E%7B-6%7D%5D)

Now the Height is mathematically represented as
