4. Priya notices thet the pressure inside one of her car tyres is too low. She pumps up the tyre to a higher pressure. a) What happens to the number of particles in the car tyre? b) What happens to the distance between particles as pressure increase? c) One of the tyres gets a puncture(small hole) . What happens to the pressure inside the tyre?

in this image, you can see solar radiation going through ocean water.

no image, but probably absorption

can be answered using momentum.

momentum = p

p1= mass1 * velocity1

p1 = p2

therefore

p1 = 6kg * 4m/s

p1 = 24kgm/s

p2=m2 * v2

24 kgm/s = 7kg * v2

v2 = 24 kgm/s / 7kg

v2= 3.42 m/s

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
