How do we calculate the weight of an object and explain why we calculate it this way.

The heaviness of an object is the power of gravity on the item and might be characterized as the mass occasions the quickening of gravity, w = mg. Since the weight is power, its SI unit is the newton. Thickness is mass/volume.

Hoped this helped :)

get the total number of pieces of fruit and divide it by 4 to get the average. the result is the answer to the problem. 14 total number of fruits and there are 4 members. 14 divided by 4 is equals to 3.5.

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me
