Answer:
d.all of the above
Explanation:
The physical feature of the planet Earth affect people's activities in the following manner -
- Choice of Occupation - the process of occupation is completely a land depended process , hence any changes on the physical features of Earth , like the climate , temperature , rain etc , will hinder the occupations process .
- Method of transportation - it is also a Climate dependent process , so any change in climate may obstruct the transportation facility .
- Recreational activities - also depends on the physical feature of the planet Earth .
The S.I unit of velocity is m/s and since it's velocity it needs to be in a particular direction, therefore most appropriate answer is :
B. She is running west at 2.4 m/s
The time required by the car to stop is 4.916 sec.
Since the car is moving with the constant deceleration we can apply the first equation of motion to calculate the time required by the car to stop.
The first equation of motion is given as
V=u+at
Here, V=final speed of the car=0 mi/h as the car stops
u =initial speed of the car=55 mi/hr=24.58 m/s
a= acceleartion =-5 m/s^2 (here negative sign indicates for deceleration)
Now applying the values in the first equation
V=u+at
0=24.58-5*t
t=4.916 sec
Therefore the car will stops in 4.916 sec.
Cell phones use RF waves from nearby cell towers. RF waves fall in between FM radio waves and microwaves
Current can vary in different branches of a circuit
