It's definitely not one of the graphs you gave us to choose from.
Answer:
The average velocity is 50 km/h south
Explanation:
The average velocity of an object is its total displacement divided by
the total time taken.
That means it is the rate at which an object changes its position from
one place to another.
Average velocity is a vector quantity.
The SI unit is meters per second.
A bicycle that starts 100 km south and is 120 km south of town after
0.4 hour.
The displacement = 120 - 100 = 20 km south
The time = 0.4 hour
The average velocity =
, where D is the displacement
and t is the time
The average velocity of the bicycle =
km/h
<em>The average velocity is 50 km/h south</em>
If you want it in meter per second, change the kilometer to meter
and change the hour to seconds
1 km = 1000 m
1 hour = 60 × 60 = 3600 seconds
The average velocity of the bicycle =
m/s south
Answer:

(c). The deflection angle is 
Explanation:
Given that,
Mass of earth 
Radius of earth 
Mass of white dwarf 
Radius of white dwarf 
Mass of Neutron 
Radius of neutron 
We need to calculate the deflection angle for earth
Using formula of angle

Where, R = radius
G = gravitational constant
M = mass
c = speed of light
Put the value into the formula


The deflection angle is 
We need to calculate the deflection angle for white dwarf
Using formula of angle

Put the value into the formula


The deflection angle is 
We need to calculate the deflection angle for neutron star
Using formula of angle

Put the value into the formula


The deflection angle is 
Hence, This is the required solution.
C. The membrane is inside the cell wall. The cell wall surrounds the membrane.
Answer:
a = (v² − v₀²) / (2 (x − x₀))
Explanation:
v² = v₀² + 2a(x − x₀)
Subtract v₀² from both sides.
v² − v₀² = 2a(x − x₀)
Divide both sides by 2 (x − x₀).
(v² − v₀²) / (2 (x − x₀)) = a
