Question 9 unsaved how are speed and velocity different?

The distance covered by the body in a given interval of time is called speed. The displacement of the something in a clear time is called speed.  

Speed decides how quick something is moving? Whereas, velocity figures out what direction something is moving?  

Speed is a scalar quantity- it is the magnitude of velocity. Speed is estimated in units of separation divided by time, e.g. miles every hour, feet every second, meters every second and so on.  

Velocity is a vector quantity – when giving the velocity we should determine the magnitude (the speed) and the direction of movement.  

At the point when the moving body comes back to the beginning stage, average velocity will be zero, but this isn't on account of average speed.

the earths atmosphere is made up of nitrogen and oxygen. solids can turn into gasses through a process called sublimation. sublimation is the transition of a substance directly from the solid to the gas phase, without passing through the intermediate liquid phase.

hope this : d

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min
