T<u>he statement which fairly compares segment 2 and segment 3 </u>is These represent equal periods of time, but the force during segment 2 is different than the force during segment 3.
Since segment 2 starts at t = 60 s and ends at t = 150 s, the time interval is Δt = 150 - 60 = 90 s.
Also, segment 3 starts at t = 150 s and ends at t = 240 s, the time interval is Δt = 240 - 150 = 90 s.
So, their time periods are the equal.
We notice that segment 2 is less steep than segment 3 this implies that the acceleration in each segment is different, since the acceleration is the slope of the graph.
Since force is determined by acceleration, this implies that the force on segment 2 is different form the force acting in segment 3.
So, we have equal time periods but different forces.
So, <u>the statement which fairly compares segment 2 and segment 3 </u>is These represent equal periods of time, but the force during segment 2 is different than the force during segment 3.

1A)
x=v0x*t=v0cosθ*t
x=52co31*3.2=142.6 m
1B)
y0=1/2gt^2-v0y*t=1/2gt^2-v0sinθt
y=0.5*9.8*3.2^2-52*sin31*3,2=23.4 m
2A)
x=2v0^2sin(2θ)/g
v0=[xg/2sin(2θ)]^1/2=14.4 m/s
the initial speed relative to the ground is
v=v0-4.4=10 m/s
2B)
fly time is
t=2voy/g
t=2*14.4/9.8=2.94
2C)
mgy=1/2mv0y^2
y=v0y^2/(2g)=10.58 m
Answer:
Atomic size
Explanation:
In the periodic table , atomic size is indirectly proportional to the effective nuclear charge .the atomic size reduces from left to right across the table. This is because electrons are added to the same shell.
Answer:
The rate at which the pump moves oil is 1 m³/s
Explanation:
Assumptions:
- there is steady-state flow
- oil and water are incompressible
- first fluid is water, second fluid is oil and third fluid is the mixture of oil and water.
where;
ρ is the fluid density
Q is the volumetric flow rate
Substitute in Q₃ in equation i
divide through by ρ₁
Make Q₂ the subject of the formula
Therefore, the rate at which the pump moves oil is 1 m³/s
