Answer:
Explanation:
At t = 1 velocity = 0
At t = 3 velocity = 3
slope of the line = 3-0 / 3-1 = 3/2
At t = 2
velocity = 3/2 x ( 2 - 1 )
= 1.5 m /s
velocity at t = 2 is 1.5 m /s
Position at t = 2 :
displacement at t = 2
area of graph upto t = 2
= 1 / 2 x 1 x 1.5 = .75
position at t = 2 :
= initial position + displacement
= 10 + .75 = 10.75 m
position at 6 s :
displacement at t = 6
area of curve upto t = 6
= 1 / 2 x 2 x 3 + 3 x 3 + 1/2 x 3 x ( 4.5 - 3 )
= 3 + 9 + 2.25
= 14.25 m
position at t = 6
= initial position + displacement
= 10 + 14.25 = 24.25 m
position at 9 s :
displacement at t = 9
area of curve upto t = 9
= 1 / 2 x 2 x 3 + 4 x 3 + 1/2 x 4 x ( 5 - 3 )- 1/2 x 2 x 1.5
= 3 + 12 + 4 - 1.5
= 17.5 m
position at t = 9
= initial position + displacement
= 10 + 17.5 = 27.5 m
The answer is:
A) Biotic and non living
The explanation:
when Biotic refers to the component of living things that are part in ecosystem. Nonliving meaning a certain thing or the table does not have any life but it's biotic.
and we here have a wooden table that is derived from a living thing like a tree and it is nonliving as its a table.
Answer:
The length of its year.
Explanation:
When Earth completes a full rotation, a year has completed. So, the same can be the same for other orbiting planet. The moon for example takes 29.5 days to revolve around the Earth, so one moon year is 29.5 Earth days.
The statement ‘The three major scales used to measure earthquakes are Mercalli Scale, Richter Scale and Magnitude Scale’ is true. These three scales used to measure the seismic waves released by the earthquake.
