(1 Point)
O
Atoms cannot be divided.
An atom is mostly empty space.
In an atom, electrons orbit the nucleus like planets orbit the sun.
O An atom includes electrons embedded in a sphere of positive charge.

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 .

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards

causes

fossil fuels burn

cities become more industrialized

human population grows worldwide
