Answer:
b) 252 Hz or 260 Hz
c) 0.25 s
Explanation:
b) The frequency of the beats is 4 Hz, and one tuning fork has a frequency of 256 Hz. Therefore, the second tuning fork is either 4 Hz lower or 4 Hz higher.
f = 252 Hz or 260 Hz
c) Period is the inverse of frequency.
T = 1/f
T = 1 / (4 Hz)
T = 0.25 s
Answer:
C. Struggle for existence
Explanation:
Have a great day
The distance traveled by the egg after 2 seconds is 19.6 m.
The given parameters:
- <em>Height of the window, h = 40 m</em>
The distance traveled by the egg after 2 seconds is calculated as follows;

where;
- <em />
<em> is the initial vertical velocity of the egg = 0</em> - <em>g </em><em>is acceleration due to gravity = 9.8 m/s²</em>
- <em>t </em><em>is the time of motion, = 2 s</em>

Thus, the distance traveled by the egg after 2 seconds is 19.6 m.

Answer:
W = 85.73 m
Explanation:
given,
surveyor walks = 118 m
makes an angle of = 36.0° with the tree
to find the width of the river




W = 85.73 m
hence, the width of the river is equal to W = 85.73 m
