Sally consumed 2. 5 gallons of water in one day. How many milliliters are equal to 2. 5 gallons, if 1 liter = 1,000 milliliters and 1 gallon = 3. 785 liters.

low freq = 100 mhz

low wavelength =101.7m

length = 3x10^8/freq

c)as speed changes, wavelength and frequency change.

everything changes!

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
