If an object weighs 40 n on earth, would it weigh more than 40 n on the moon? explain.

Weight on the surface of moon is smaller than 40 N

Explanation:

As we know that weight is gravitational attraction force of the planet on the objects near the surface of the planet

So we will say

here we know that at the surface of earth the weight is given as

so we have

so when same object is taken at the surface of moon then we will have

since gravity on the surface of moon is smaller than the gravity at the surface of Earth

so weight will be less than 40 N

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
