The movement of water molecules from higher to lower concentration is osmosis.
C. Hypothesis
The hypothesis is presented as an explanation of the observed results.
First the aceleration:
Vf² = Vo² - 2ad
a = (Vf² - Vo²) / 2d
a = (0 m/s)² - (1,5 m/s)²) / 2 * 0,4 m
a = -2,25 m²/s² / 0,8 m
a = -2,81 m/s²
Now, for the net force, use 2nd law of Newton:
F = ma
F = 3,5 kg * (-2,81 m/s²)
F = -9,835 N
The force for stop the bowling ball is <u>-9,835 Newtons.</u>
a)
Amplitude of wave is given as maximum displacement from mean position
So here amplitude is 1.25 cm
b)
Wavelength is the length of the wave that it travels in one time period
From graph we can say the wavelength is given as 3cm
PART C)
Time period of wave is the time after which it repeats its shape
Speed of the wave = 21 cm/s
time period = wavelength / speed
Now frequency is
PART D)
Time period = \frac{1}{f}[/tex]
Balance:
a book resting on a table
a car driving at 10 miles per hour in constant velocity
a cat sitting on a chair
a bulb that attach to the ceiling
your grandma sleeping on a bed
Unbalance:
your brother sprinting across the kitchen
a ball rolling at 5 m/s^2
your mom trying to run at 2 m/s^2 to spank you
you dropping your coffee mug on a floor
a cat jumping out of your bed
a tear from your eye falling through the floor
Hope this helps
