Hooke’s law states that the distance that a spring is stretched by hanging object varies directly as the mass of the object. if the distance is 140 cm when the mass is 21 kg, what is the distance when the mass is 5 kg?

= 33.33 cm

Explanation:

Given:

When mass, =21 kg

          distance travelled is    = 140 cm

When mass, =5 kg

         distance travelled is    = ?

Hooke's law state that within elastic limit, when an external force is applied to a body, the body gets deformed and when the force is released the gets back to its original form.

Therefore according to the question,

= 33.33 cm

Distance travelled is 33.33 cm when mass is 5 kg.

when the use of electricity burdens the fuse and miniarure circuit beakers and there is a possibility of a fuse then they automatically cut off the electricity supply to your homes and after you fix the problem u jzt switch it on and it continues the supply of electricity to ur homes

it is very well related to a lot of things but with my limited knowledge i can confidently say that the answer is space.
