Answer:
V = 3.5 x 10⁻⁶ m³/s = 3.5 cm³/s
Explanation:
The volume flow rate of the blood in the artery can be given by the following formula:
where,
V = Volume flow rate = ?
A = cross-sectional area of artery = πd²/4 = π(0.004 m)²/4 = 1.26 x 10⁻⁵ m²
v = velcoity = 0.28 m/s
Therefore,
<u>V = 3.5 x 10⁻⁶ m³/s = 3.5 cm³/s</u>
Let
dV = dt = water is flowing in at a rate of 12 ft3 / min.
h = the depth of the water.
dh / dt = the rate of change of the depth.
First you must find the volume of the cone as a function of "h". Then you must derive the volume of the cone with respect to time. Finally clear dh / dt.
I attach the solution.
Answer:
T = 29.6 N
Explanation:
length of the rope is
L = 18 m
mass of the rope is
m = 12 kg
now we have
mass per unit length of the rope is given as
[te]\lambda = \frac{12 kg}{18 m}[/tex]
now time taken by wave to reach from end to other
now we have
so we will have
72 m is the horizontal distance the ball travels in 2 seconds.
Answer: Option C
<u>Explanation:</u>
Velocity is defined as the distance travelled per unit time and expressed in m/s. The mathematical expression can be given as follows,
Now, the given datas are,
Angle made with the horizontal= 12 degrees
Velocity with which the ball was hit= 37 m/s
Time travelled= 2 s
The range ‘x’ of the horizontal component’s velocity can be calculated by,
So, horizontal component of velocity,
Now, horizontal distance travelled can be measured as,
The value gets rounded off and the horizontal travelled distance as 72 m.
