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 .
Answer:
v = 3 m/s
Explanation:
P is the momentum
m is the mass
v is the velocity
P = m•v
300 = 100•v Divide both sides per 100
300/100 = v
v = 3 m/s
Answer:
Technician A is correct.
Explanation:
Stroke of the engine means how far is the piston moves during the cycle.It is determined by the crank of the crank shaft. Engine displacement volume is calculated by multiplying length of the stroke to the piston displacement area.
If there are more than one cylinder in the engine, than in that case this number in multiplied by the number of the cylinders inside the engine.
Therefore technician A is correct.
Acceleration is the change of velocity, and velocity is the change of distance. The opposite of finding change, or differentiation, is integration.
Acceleration = 1.3 m/s²
Velocity: ∫ 1.3 dx = 1.3x + c m/s
Distance: ∫ 1.3x dx = 1.3x²/2 + c m
Distance run: 1.3*3²/2 = 5.85 m
