I will mark you brainlist please help
1) A ball is thrown with the speed of 10 m/s from the 1st stair. The height of each stair is 10cm and the width is 15 cm. on which stair the ball will fall
The frequency of a 4,600 cm wave is 652 Hz
Frequency is the number of waves that pass a fixed point in unit time
Here given data is
Wave = 4,600 cm = 4.6 × 10⁸ nm
We have to calculated frequency = ?
Frequency =v = c/λ
Frequency = 3×10⁸m / 4.6 × 10⁸ nm
Frequency = 652 Hz
Know more about frequency

~Hello There!~
35 - 18 = 17
17 electrons means 7 outer shell electrons
Group number 7 - The Halogens
Electron configuration is 2. 8. 7
3 shells therefore in period 3
Hope This Helps You!
Good Luck :)
Have A Great Day ^_^
