The final velocity is 5.2^2. The initial velocity is 0 . You are using Kinematic equation 3. (V^2=Vo^2+2a(x)) . (5.2^2=2(2.8)x)
27.04=5.6x
27.04/5.6=5.6/5.6x
4.83=x
The answer is 4.83m:)
Answer:
wavelength = 0.968 m
frequency = 39.02 Hz
Explanation:
given data
mass = 0.0127 kg
force = 9.33 N
length = 1.93 m
to find out
wavelength and Frequency
solution
we know here linear density that is
linear density =
.........1
linear density =
linear density = 6.5803 ×
kg/m
so
wavelength will be here
wavelength =
..............2
here n = 4 for forth harmonic
wavelength = 
wavelength = 0.968 m
and
frequency will be for 4th normal mode of vibration is
frequency =
..........3
frequency = 
frequency = 1.036269 × 37.654594
frequency = 39.02 Hz
Answer: In places of hot climate it is advised that the outer wall of houses be painted white because white color reflects heat and the houses do not heat up too much.
V = (1 / p) × p0 × V0
1 / p = V / (p0 × V0)
p = (p0 × V0) / V = (49kPa × 11L) / 4L = 134.75kPa
