Answer:
The maximum speed of the car at the bottom of that drop is 26.34 m/s.
Explanation:
Given that,
The maximum vertical distance covered by the roller coaster, h = 35.4 m
We need to find the maximum speed of the car at the bottom of that drop. It is a case of conservation of energy. The energy at bottom is equal to the energy at top such that :
v = 26.34 m/s
So, the maximum speed of the car at the bottom of that drop is 26.34 m/s. Hence, this is the required solution.
There is no picture attached so we can’t see the answers
I hope I can help! :)
A concave mirror is when the object is anywhere from infinity to focus the image so form will be real and inverted.
And when the object is between pole and focus of concave mirror then image so formed will be virtual and erect and the size of image is greater than size of object.
So, the answer would be "where light rays disperse."
Have a great day/evening/night! :)

Answer:
2.25 kg
Explanation:
Length, L = 6 m
tension, T = 600 N
velocity, v = 40 m/s
The formula for the velocity is given by
where, μ is mass per unit length
μ = 0.375
m / L = 0.375
m = 0.375 x 6 = 2.25 kg
Thus, the mass of rope is 2.25 Kg.
