Answer: 4
Explanation:
The dependent variable is the temperature of the water.
Compressions are the areas of high pressure while rarefractions are low pressure area
Answer:
This question is incomplete
Explanation:
This question is incomplete because of the absence of the time taken to complete one full cycle.
Frequency (<em>f</em>) will be calculated first as
<em>f </em>= <em>N </em>÷<em> t</em>
where <em>N </em>is the number of cycles and <em>t </em>is the time taken to complete one full cycle. The unit for frequency is Hertz (Hz).
To calculate the period, <em>T, </em>the formula below will be used
<em>T </em>= 1 ÷ <em>f</em>
The unit for period is secs
Answer:
a. acceleration (a) = 4.9 m/s²
b.
c. see the attached diagram below
d V = 0.048 m/s
e. The viscosity u = 0.27 Ns/m²
Explanation:
Given that :
m = 5 kg
A = ( 0.1 m )²
d = 0.20 mm
θ = 30 °
By applying Newton's second Law ; we have
F = mgsinθ - (since no friction ; then
ma = mg sinθ
a = gsin θ
a = 9.8 × sin 30
a = 4.9 m/s²
b) By applying Newton's second law at any instant .
ma = mgsin θ -
and = T×A = -
Also; ma =
∴ ma = mg sin θ -
separating the variables ; we have
By integrating using limits ; we have:
∴
c) The curve for V(t) plot is attached in the diagram below.
d)
To find the speed after 1 sec; we have:
at t = 1.0 sec;
V =
V = 0.048 m/s
e) In order to determine the viscosity for which V(0.1) = 0.3 m/s ; we have the following.
∴
The viscosity u = 0.27 Ns/m²
It can be fueled like a normal car but has electric motor and battery
