Answer:
50 N ---->
Explanation:
Opposing sides get subtracted so~
25-25 cancels out to zero so there is 0N
100 -50 equals 50 N ->
Because it's maybe the only color they see.
60 meters, because he starts at point A and moves with a constant velocity of 0.5 m/s for 120s,
0.5x120=60
so the displacement is 60 meters, because the displacement is the distance between the starting point and the finishing point.
Thanks and you have a good day too
Answer:
Length of pendulum, l = 1.74 meters
Explanation:
The time period of simple pendulum is, ![T=2\pi\sqrt{\dfrac{l}{g}}](https://tex.z-dn.net/?f=T%3D2%5Cpi%5Csqrt%7B%5Cdfrac%7Bl%7D%7Bg%7D%7D)
Where
l is the length of simple pendulum
The time period of uniform thin rod is hung vertically from one end is, ![T=2\pi\sqrt{\dfrac{2l'}{3g}}](https://tex.z-dn.net/?f=T%3D2%5Cpi%5Csqrt%7B%5Cdfrac%7B2l%27%7D%7B3g%7D%7D)
l' is the length of uniform rod, l' = 2.6 m
It is given that the rod and pendulum have same time period. So,
![2\pi\sqrt{\dfrac{l}{g}}=2\pi\sqrt{\dfrac{2l'}{3g}}](https://tex.z-dn.net/?f=2%5Cpi%5Csqrt%7B%5Cdfrac%7Bl%7D%7Bg%7D%7D%3D2%5Cpi%5Csqrt%7B%5Cdfrac%7B2l%27%7D%7B3g%7D%7D)
After solving above expression, the value of length of the pendulum is, l = 1.74 meters. Hence, this is the required solution.
