Do you support trucks are identical each box loaded on the truck has the same mask choose the truck that has the greatest force

Anestetic [448]

gravitational force of earth is given by

$F = mg$

so here the force will depend on the product of mass and gravity

so here force will be more if we took the condition of more masses

so here in 3rd figure

there will be maximum force of gravity on it

because it will have 6 boxes so there will be maximum mass

So figure of truck with 6 boxes on it is correct answer

Does an object in rest have potential energy

kenny6666 [7]

Yes, of course! by it's definition the potential energy is an energy that particle have in order to obtain kinetic energy. Or simply an energy to make some movement.

calcula el potencial electrico de un punto B que se encuentra a 75cm de una varga positica q=9×10-6c

ankoles [38]

Answer:

V = 72000 volts

Explanation:

calculates the electric potential of a point B that is 75cm from a positive charge q = 9 × 10-6c

Given that,

Electric charge, $q=9\times 10^{-6}\ C$

We need to find the electric potential of a point B that is 75 cm from this charge. The formula for the electric potential is given by :

$V=\dfrac{kq}{r}\\\\V=\dfrac{9\times 10^9\times 6\times 10^{-6}}{0.75}\\\\V=72000\ V$

So, the electric potential is equal to 72000 Volts.
