Answer:
0.75Hz
Explanation:
Given parameters:
Speed of the wave = 3m/s
Wavelength = 4m
Unknown:
Frequency of the wave = ?
Solution:
The speed of a wave is given by the expression below:
Speed = frequency x wavelength
Frequency =
=
= 0.75Hz
Pull and motion effects :)
Answer:
t=L/
Explanation:
<u>solution:</u>
Let E be an observer, and B a second observer traveling with velocity
as measured by E. If E measures the velocity of an object A as
then B will measure A velocity as
=
-
Applied here,
the walkway (W) and the man (M) are moving relative to Earth (E}, the velocity of the man relative to the moving walkway is
=
-
,

The time required for the woman, traveling at constant speed
relative to the ground, to travel distance L relative to the ground is
:
t=L/
Answer:
the answer would be B your welcome
Explanation:
Hello!
The <span>biochemical process that liberates energy content of food for living organs is called catabolism.
Catabolism is a process in which big molecules like those in the food we eat are broken down into small ones that can be used by the living organism to obtain energy. The energy that is liberated in this process is stored in molecules of adenosine triphosphate (ATP). These molecules are used by cells to produce energy in the process called cellular respiration, catalyzed by the enzyme ATPase.
Have a nice day!
