Answer:
v2=0.79 m/s
Explanation:
equation of continuity: V1A1=V2A2
A=(pi)r^2
A1=(pi)(0.55cm)^2
A2=(pi)(1.17cm)^2
convert cm2->m2
A1= 0.95cm2=
A2= 4.3cm2=
(3.57 m/s)(0.000095 m^2)=(x m/s)(0.00043 m^2)
v2=0.79 m/s
hope this helped
Answer:
Multiply the length, width and height of the brick to calculate its volume.
Explanation:
This is because warm water vapor, suspended in the air, transforms back into water droplets as it cools. These small droplets collect on surrounding surfaces and are especially noticeable on materials such as glass since they distort light waves, making the mirror and windows appear foggy or misty
You haven't told us what any of those letters represents.
I'm going to assume that ...
-- ' P ' = power
-- ' I ' = circuit current
-- ' V ' = circuit voltage
-- ' E ' = energy
-- ' t ' = time.
Now I'm ready to answer the question that I just invented.
P = I / V
V = P x I
Both of these are false statements, and can't be used to calculate anything.
P = I x V is the correct equation to calculate electrical power.
<em>E = P x t</em> is the correct equation to calculate electrical energy.
