Well, since the question GIVES you the initial velocity, the acceleration, and the time, and ASKS for the final velocity, you'd be smart to find an equation that USES the initial velocity, the acceleration, and the time, and FINDS the final velocity.
Have a look at equation B ..... vf = vi + a*t . That's pretty durn close !
vf = (initial velocity) + (acceleration)*(time)
vf = (3 m/s) + (5 m/s²)*(4 sec)
vf = (3 m/s) + (20 m/s)
vf = 23 m/s
Here a cat is running at constant speed which is given as 10 km/h for 5s
So here the average speed is defined as total distance moved in total time interval
so here it is given by
since
here speed of cat is constant so it will remain the same
And hence the average speed and instantaneous speed at any instant for this duration will remain the same
so here answer would be
<em>average speed = 10 km/h</em>
<em>instantaneous speed = 10 km/h</em>
When white light is diffracted and blue color is seen is due to the absorbance of wavelength of all other color except blue.
<u>Explanation:
</u>
- The white light diffracts into rainbow colors which are the 7 colors present in form of VIBGYOR.
- VIBGYOR is the violet, Indigo, Blue, Green, Yellow, Orange and Red.
- When the blue color is seen denotes the shortest wavelength being reflected and all other being absorbed at the specified location.
