Answer:In first case
Explanation:
When two People pull the spring, let the applied force by each person be
and spring constant of spring be k
so Total force is
total extension according to Hooke's law is
When they detach the spring and apply force in opposite direction then force on either side is F so net extension is
so in first case there will be more extension
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
Now the Height is mathematically represented as
