The frequency produced by the string could be 437 Hz or it could be 443 Hz.
The frequency of the beats ... 3 Hz ... tells the piano tuner that
the difference between the fork and string frequencies is 3 Hz,
but it doesn't tell her which one is higher or lower.
The force that opposes the start of motion is referred to as static friction.
Friction is a force that opposes motion in general, and static friction opposes initial movement. This is because, when two objects are stopped near one another, weak bonds begin to form between the atoms on their surfaces. These bonds must be broken in order for one object to move away from the other. This resistance caused by the bonds between motionless objects is static friction.
Answer:
This question can only be answered by you.
Explanation:
This question must be tailored specificly to you. whatever your next class is you must write 8 sentences on your walk to it. You can try going into detail about who you saw on the walk. where you went.what people were doing in the hallway. Did you look out a window? what did you see? how long did it take you to walk there? do you usually stop at your locker?
Also dont forget to use a colon ( : ): This can be used when listing things
semicolon (;) : is used as a pause (Seperation) in a long sentence.
Try incorperating some of the five senses in your sentences.
Good luck!
Answer:
11.2°
Explanation:
Using the trigonometry ratio,
Note: Assuming the ladder, the wall and the horizontal forms a right angle triangle.
Cosθ = Opposite/Hypotenuse
SinΦ = O/H.......................... Equation 1
Where Φ = angle between the ladder and the wall, O = opposite, H =Hypotenuse.
make Ф the subject of the equation,
Ф = sin⁻¹(O/H).................. Equation 2
Given: O = 3.3 foot, H = 17 foot
Ф = sin⁻¹(3.3/17)
Ф = sin⁻¹(0.194/
Ф = 11.19°.
Ф = 11.2° ( to the nearest tenth degree)
Hence the ladder and the wall makes an angle of 11.2°
