M, mass=84 kg
height, h=3.9m
gravity, g= 9.8m/s2
W = F . d
F=force
d=Displacement
W=work done by force
Now by putting the values
F= m g (Acting downward )
d= h (Upward)
W= m g h ( work done against the force)
W= 84•9.8•3.9J
W= 3210.48
Therefore the answer will be 3210.48J.
Answer:
air does not have a modulus of rigidity.
Explanation:
Since air is completely elastic medium, that is, it does not have a modulus of rigidity, therefore sound waves in air are longitudinal.
It’s 4. Definitely 4. 99% sure it’s 4.
Answer:
It will take 126.84 years to pay off the debt
Explanation:
Total debt = $14,000,000,000,000.00
Paid $3,500 per second
Number of seconds to pay off the debt will be:
14 ×10^12 /3500
Number of seconds = 4× 10^9 seconds
Converting seconds to year:
I second = 3.171 ×10^-8 calendar year
Therefore, number of years it will take to pay off $14 Trillion =( 4 ×10^9 ) × ( 3.171 × 10^-8)
Number of years = 126.84 years
Answer:
K2 = N*K1
Explanation:
The force you apply to each section is the same you apply to the whole spring, but the extension of each section is dX/N (if dX is the extension of the entire spring)
