A convergent meniscus lens is a lens that is composed of two spherical surfaces, like the on shown next:
The imaginary line that runs through the middle of the lens is the "symmetry axis".
In this type of lenses incident parallel beams of light converge in one point, as follows:
And thus we get the diagram.
Answer:
(a). The speed is 115.28 m/s.
(b). The time is 94 min.
(c). The International Space Station travels 43202.400 km.
(d). Speed is scalar quantity.
Velocity is vector quantity.
Explanation:
Given that,
Top speed = 415 km/h
1 miles = 1609 m
(a). We need to calculate the speed in m/s
Using conversion of km/h to m/s
(b). We need to calculate the distance from London to Edinburgh in km
Using conversion for distance
Distance in meter,
We need to calculate the time
Using formula of time
Put the value into the formula
(c). Speed v' =7.66 km/s
v'=7660 m/s
In the time it takes the car to travel from London to Edinburgh,
We need to calculate the distance
Using formula of distance
Put the value into the formula
(d). Speed :
Speed is equal to the distance divided by time.
It is scalar quantity.
Velocity :
Velocity is equal to the displacement divided by time.
It is vector quantity.
Hence, (a). The speed is 115.28 m/s.
(b). The time is 94 min.
(c). The International Space Station travels 43202.400 km.
(d). Speed is scalar quantity.
Velocity is vector quantity.
