Two forces act an angle of 130. If the greater force is 60 N and their resultant is perpendicular to the smaller force, the smaller force is ? (a) 0 N
(b) 38.57N
(c) 300 N
(d) 25 N​

r=rho l/a where a is the area, l is the length and rho is resistivity so the greater the area the lesser the resistance thats why the earth pin is thicker bcos current follow the shortest path, so less resistive .

c because the news are a source of information of things that happen on the daily and shows evidence about that particular topic

  the unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is
