Step-by-step explanation:
It's already rounded as far as it will go
Answer:
percentage = 85%
Step-by-step explanation:
total percentage =
- = total coloured boxes / total boxes × 100
- = (85 / 100) × 100
- = 85%
Answer:
The time period of a simple pendulum if it takes 72 seconds to complete 24 oscillation will be 3 seconds.
Step-by-step explanation:
Total number of oscillations = 24
Time taken to complete 24 oscillations = 2 seconds
So, the frequency 'f' of the simple pendulum will be:
![f=\frac{24}{72}](https://tex.z-dn.net/?f=f%3D%5Cfrac%7B24%7D%7B72%7D)
![f=\frac{1}{3}](https://tex.z-dn.net/?f=f%3D%5Cfrac%7B1%7D%7B3%7D)
Let 'T' be the time period.
![T=\frac{1}{f}](https://tex.z-dn.net/?f=T%3D%5Cfrac%7B1%7D%7Bf%7D)
![T=\frac{1}{\frac{1}{3}}](https://tex.z-dn.net/?f=T%3D%5Cfrac%7B1%7D%7B%5Cfrac%7B1%7D%7B3%7D%7D)
![\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{1}{\frac{b}{c}}=\frac{c}{b}](https://tex.z-dn.net/?f=%5Cmathrm%7BApply%5C%3Athe%5C%3Afraction%5C%3Arule%7D%3A%5Cquad%20%5Cfrac%7B1%7D%7B%5Cfrac%7Bb%7D%7Bc%7D%7D%3D%5Cfrac%7Bc%7D%7Bb%7D)
![T=\frac{3}{1}](https://tex.z-dn.net/?f=T%3D%5Cfrac%7B3%7D%7B1%7D)
![T=3](https://tex.z-dn.net/?f=T%3D3)
Therefore, the time period of a simple pendulum if it takes 72 seconds to complete 24 oscillation will be 3 seconds.
For example, sinD = 7/25; cosD = 24/25; tgD = 7/24;
