Answer:
The equivalent stiffness of the string is 8.93 N/m.
Explanation:
Given that,
Spring stiffness is
According to figure,
and is in series
We need to calculate the equivalent
Using formula for series
Put the value into the formula
k and is in parallel
We need to calculate the k'
Using formula for parallel
Put the value into the formula
,k' and is in series
We need to calculate the equivalent stiffness of the spring
Using formula for series
Put the value into the formula
Hence, The equivalent stiffness of the string is 8.93 N/m.
Answer:
Gravity, Weak, Electromagnetic and Strong.
Answer: The correct answer is B
Explanation: The string is pulling right and the string is unraveling causing it to accelerate left
I believe the sun is the primary source of energy for Earth's weather system. The sun is the primary energy source for Earth's climate system which is the first set of essential principles of climate sciences. Additionally, it is the primary source that drives all weather events, including precipitation, hurricane and tornadoes. The sun drives the hydrologic cycle, and makes life on Earth possible.
