Which of the following changes would increase the seperation between the bright fringes in the diffraction pattern formed by diffraction grating?A. INCREASE THE WAVELENGTH OF THE LIGHTB. IMMERSE THE APPARATUSE IN WATERC. INCREASE THE SEPERATION BETWEEN THE SLITSD. NONE OF THESEE. MORE THAN ONE OF THESE

that tool is called an altimeter which measures your altitude which can be used to tell which atmosphere you are currently in, including the stratosphere.

hope this ! : )

the minimum constant speed at which she can catch the train is 2.7 m/s

given:

acceleration = 0.6

time = 4.5 s

to find:

velocity = ?

formula used:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

solution:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

v = 0 + (0.6 × 4.5)

v = 2.7 m/s

the minimum constant speed at which she can catch the train is 2.7 m/s

pretty sure it's false
