A block of mass 5 kg slides down an inclined plane that has an angle of 10. If the inclined plane has no friction and the block

starts at a height of 0.8 m, how much kinetic energy does the block have when it reaches the bottom? Acceleration due to gravity is g = 9.8 m/s2

The kinetic energy of the block  when it reaches the bottom is 39.2 J.

<h3>Kinetic energy of the block at the bottom</h3>

Apply the principle of conservation of energy.

K.E(bottom) = P.E(top)

P.E(top) = mgh

where;

  • m is mass of the block
  • g is acceleration due to gravity
  • h is the vertical height of fall

P.E(top) = 5 x 9.8 x 0.8

P.E(top) = K.E(bottom) = 39.2 J

Why is the voltage of the supply decreased before entering our homes ?
Reptile [31]

Answer:

After power is generated at a power plant, its voltage is increased by a step-up transformer. The power then travels through transmission lines to a neighborhood where it will run homes, offices, and factories. But before entering the neighborhood, the power's voltage is decreased by a step-down transformer

Transformers can be used either to increase the voltage (called "stepping up") or decrease the voltage ("step down"). When electrical energy travels long distances in wires, some of the energy is lost. ... Later, the voltage is stepped down before it enters your home - once again using transformers
