Answer:
$ 3085713685.71
Explanation:
= Actual wavelength = 700 nm
= Changed wavelength = 500 nm
Let the wavelength of red color be 700 nm and green be 500 nm
Change in wavelength is
We have the relation
The speed of the vehicle is 85714285.7143 m/s
By how much was the car speeding
The number of 10 km/h in the above speed
Cost of the ticket
The cost of the ticket is $ 3085713685.71

Answer:
W=76.55 miles.metric tons
Explanation:
Given that
Weight on the earth = 12 tons
So weight on the moon =12/6 = 2 tons
( because at moon g will become g/6)
As we know that
Here x= 1100 miles
F 2 tons
So
We know that
Work = F. dx
W=76.55 miles.metric tons
One of the equations of gravity is this:
Where v = final velocity which is 7m/s
u = initial velocity which is 0 for objects falling from a height
g = acceleration due to gravity and it is approximately 10m/s^2. It's a constant so pretty much remember this number. It's positive since the work being done is caused by gravity (in other words, it's falling down). It can also be negative if the work being down is against gravity (in other words, it's going up)
h = height of object
Substitute for the values and you should have something like this
