Answer:
Explanation:
The period of oscillation is given as
T=2π√m/k
Making k subject of the formula
Square both sides of the equation
T²=4π²(m/k)
Cross multiply
T²k=4π²m
Then, divide through by T²
k=4π²m/T²
Where
k is spring constant
m is the mass of the bob
And T is the period of the oscillation
m=140g=0.14kg
14 oscillations takes 14 seconds
Then the period is
T=time/oscillation
T=14/14
T=1sec
Then,
k=4π²m/T²
k=4π²×0.14/1²
k=1.76N/m
Then, the spring constant is 1.76N/m
Quick definition: fear appeal: making someone do something out of fear of something.
I think the way it's used is that doctors make people dear disease.
Sun emits energy(light and heat) towards the earth
Incident long-wave radiation is blocked
Visible and shortwave radiation heat the earth
Earth radiates long wave radiation
