An advertisement for an all-terrain vehicle (ATV) claims that the ATV can climb inclined slopes of 35°. The minimum coefficient of static friction needed for this claim to be possible is 0.7
In an inclined plane, the coefficient of static friction is the angle at which an object slide over another.
As the angle rises, the gravitational force component surpasses the static friction force, as such, the object begins to slide.
Using the Newton second law;




N = mg cos θ
Equating both force component together, we have:



From trigonometry rule:

∴



Therefore, we can conclude that the minimum coefficient of static friction needed for this claim to be possible is 0.7

<span>Wavelength = (speed) / (frequency)
Speed of EM radiation = 3 x 10⁸ m/s
Frequency (3 × 10¹⁹ Hz) ===> wavelength = 0.01 nanometer
Frequency (3 × 10¹⁶ Hz) ===> wavelength = 10 nanometers</span>
This is the region of X-rays.
