Electromagnetic waves going through outer space has the greatest speed among all kind of waves.  

Option B

<u>Explanation</u>:  

Electromagnetic waves are the waves that can go through the vaccum of space. Electromagnetic waves are made by the vibration of an electric charge. This vibration makes a wave that has both an "electric and magnetic nature". An electromagnetic wave transfers energy through a vaccum at a speed of 3.00 \times 10^{8} \mathrm{m} / \mathrm{s}(speed esteem ordinarily depicted by the sign c). The spread of an electromagnetic wave through a material medium happens at a net speed which is under 3.00 \times 10^{8} \mathrm{m} / \mathrm{s}.

The static friction exerted on the block by the incline is \mu _ s _1 Mgcos \ \theta.

The given parameters;

  • <em>mass of the block, = M</em>
  • <em>coefficient of static friction in section 1, = </em>\mu_s_1<em />
  • <em>angle of inclination of the plane, = θ</em>

<em />

The normal force on the block is calculated as follows;

Fₙ = Mgcosθ

The static friction exerted on the block by the incline is calculated as follows;

F_s = \mu_s F_n\\\\F_s = \mu _s_1(Mg cos\ \theta)\\\\F_s = \mu _s_1 Mgcos\ \theta

Thus, the static friction exerted on the block by the incline is \mu _ s _1 Mgcos \ \theta
