<span>Breaking down is an emergency situation.
If your vehicle breaks down pull off the roadway, and if possible, park so that your vehicle can be seen for 200 feet in each direction.You should also m</span>ove the vehicle so all four wheels are off the pavement and turn on the emergency flashers. If there are other passengers in the car they should all get out <span>on the side away from traffic.</span>
Evidence for the particle nature of light are not: 1. refraction, 2. many colors of light, 3. diffraction. These are all phenomenon that support wave theory of light. Evidence for particle nature of light is photoelectric effect. Because it was discovered that you need discrete energies of light to eject electrons from a metal surface and not continuous as the wave theory of light suggests.
Acceleration is how much the velocity changes within a period of time so,
Acceleration= is the change in velocity divided by change in time
your units will be m/s squared
The formula for this problem that we will be using is:
F * cos α = m * g * μs where:F = 800m = 87g = 9.8
cos α = m*g*μs/F= 87*9.8*0.55/800= 0.59 So solving the alpha, find the arccos above.
α = arccos 0.59 = 54 ° is the largest value of alpha
Gravity, friction, and air resistance are some examples.
