Answer:
100.11 m
Explanation:
Given:
Coefficient of volume expansion, 
/°C.
Initial length of rod, 
Change in temperature, ΔT=
°C
We know that,
/°C
Here, 
is the coefficient of linear expansion.
Now, we know that,
Change in length (Δl) is given as,
Plug in all the values and solve for 
.
This gives,
Therefore, the length of rod after expansion is 
m.
The answer is A. Plant growth, Plant growth is the only thing that can actually be tested and scientificly measured, hope this helps!!!!
we know that
the speed is equal to
The slope of the line on the graph is equal to the speed of the car
so
during the segment B the slope of the line is equal to zero
that means
the speed of the car is zero
therefore
<u>the answer is the option B</u>
The car has come to a stop and has zero velocity
Distance = 2000m
Time = 35 minutes = 35×60 sec = 2100 sec
We know, Speed = Distance/Time
Therefore, Speed
= 2000m/2100s = 20/21 m/s
Answer: 20/21 m/s
