Answer:
9375 N
Explanation:
From the question,
Centripetal force (F) = mv²/r.................. Equation 1
Where m = mass of the car, v = velocity of the car, r = radius of the curve.
Given: m = 900 kg, r = 600 m, v = 25 m/s
Substitute these values into equation 1
F = (900×25²)/600
F = 9375 N.
Hence the centripetal force on the car is 9375 N
The ones that interact would be Atmosphere, biosphere, and cryosphere. :)
To solve the problem it is necessary to apply the Malus Law. Malus's law indicates that the intensity of a linearly polarized beam of light, which passes through a perfect analyzer with a vertical optical axis is equivalent to:

Where,
indicates the intensity of the light before passing through the polarizer,
I is the resulting intensity, and
indicates the angle between the axis of the analyzer and the polarization axis of the incident light.
Since we have two objects the law would be,

Replacing the values,



Therefore the intesity of the light after it has passes through both polarizers is 
Answer: 11,100 ft/s^2
1) Constant acceleration=> uniformly accelerated motion.
2) Formula for uniformly accelerated motion:
Vf = Vo + at
3) Data:
Vo = 1,100 ft/s
a = 1,000 ft/s^2
t = 10.0 s
4) Solution:
Vf = 1,100 ft/s + 1,000 ft/s^2 * 10.0 s = 1,100 ft/s + 10,000 ft/s
Vf = 11,100 ft/s

F = k x
k = 2 g/6.1 cm
2.5g = (2g/6.1cm) x
x = 6.1 (2.5/2) cm
