A baby carriage is sitting at the top of a hill that is 21 m high. The carriage with the baby weighs 12 N. The carriage has ___ energy. Calculate it.

252 Joules.

Explanation:

From the question, we can deduce that baby carriage isn't moving and as such possess energy due to its position. This ultimately implies a gravitational potential energy.

Potential energy can be defined as an energy possessed by an object or body due to its position.

Mathematically, potential energy is given by the formula;

Where, P.E represents potential energy measured in Joules.

m represents the mass of an object.

g represents acceleration due to gravity measured in meters per seconds square.

h represents the height measured in meters.

Given the following data;

Height = 21m

Weight of carriage with baby = 12N

But we know that weight = mg = 12N

Substituting into the equation, we have;

Therefore, the energy possessed by the carriage is 252 Joules.

it would be c. predictability

force required to detach it is given by

charges are taken to be fundamental charge

now we have

so above is the minimum distance at which it will detach
