The cosmic microwave background<span> (CMB) is electromagnetic </span>radiation<span> as a remnant from an early stage of the universe in Big Bang cosmology. In older literature, the CMB is also variously known as </span>cosmic microwave background radiation<span> (CMBR) or "relic </span>radiation<span>"</span>
Answer:
V0=27.4 m/s; t=0.8 s
Explanation:
Final position y=37.0 m, time = 2.3 s; Initial position is set to be zero. We calculate the initial speed with the kinematics equation:
We solve for initial speed
Now, using the same expression we estimated time to first reach 18.5 m :
Second order equation with solutions
t1=0.8 s and t2=4.8 s
The first time corresponds to the first reach.
The perspective which best explain this is SOCIO-CULTURAL PERSPECTIVE.
Socio-cultural perspective is a theory which explains the awareness of situations surrounding people and how their behavior is determined by their environment, culture and social values.
The period of a simple pendulum is
where
L = the length of the pendulum
g = acceleration due to gravity
On earth, g = 9.8 m/s².
Therefore
On Mars, g = 0.37(9.8) = 3.626 m/s².
The period will be
Answer: 2.22 s
You wrote it yourself, right there on the paper !
What's -9/18 ?
Isn't it -1/2 or -0.5 ?
