Write difference between upstroke and downstroke of water pump

Physics
1 answer:
lakkis [162]3 years ago
7 0

Explanation:

Upstroke is a mechanism which helps to raise the plunger and downstroke helps to help lower the plunger. On the up-stroke of the plunger, the lower valve opens and the upper valve is closed. ... Whereas, on the downstroke, the lower valve closes and the upper one opens.

Circular coil 1 has N turns and circular coil 2 has 6N. Coil 1 has area A and coil 2 has area A/4. If Coil 1 has current i runni
solmaris [256]

Answer:

\frac{L_1}{L_2} =\frac{1}{3}

Explanation:

Recall that the formula for an inductance (L) for coil on N turns, are A and current I is given by:

L=\frac{\mu_0\,N^2\,A}{I}

Then, for the first coil we have;

L_1=\frac{\mu_0\,N^2\,A}{I}

and for coil 2 we have:

L_2=\frac{\mu_0\,(6\,N)^2\,(A/4)}{3\,I}

then, the quotient L1/L2 can be written as:

\frac{L_1}{L_2} =\frac{\mu_0\,N^2\,A\,3\,I}{\mu_0\,(6\,N)^2\,(A/4)\,I}=\frac{12}{36} =\frac{1}{3}

a block with a mass of 3 kg is swung on a cord in a horizontal circle with a radius of 2m. the speed of the block is 6m/s^. the
Ivenika [448]

Given Information:  

Mass = m = 3 kg

Speed = v = 6 m/s  

Radius = r = 2 m

Required Information:  

Magnitude of the acceleration = a = ?  

Answer:

Magnitude of the acceleration = 18 m/s²

Explanation:

The acceleration of the block traveling along a circular path with some velocity is given by

a = v²/r

a = 6²/2

a = 36/2

a = 18 m/s²

Therefore, the magnitude of the acceleration of the block is most nearly equal to 18 m/s².

Bonus:

The corresponding force acting on the block can be found using

F = ma (a = v²/r)

F = mv²/r

nikitadnepr [17]
I assume the element has 5 valence electrons (not neutrons).  The similar properties are shared between y and z  since they have the same number of valence electrons.  This is what is primarily responsible for chemical behavior.

What is the change in entropy per mole associated with the melting of gold? the melting point of gold is 1337k and the â†hfus is
riadik2000 [5.3K]
The entropy change<span> of the surroundings is driven by heat flow and the heat flow determines the sign of ΔS</span>surr<span>. It can be calculated by the following expression:

</span>ΔSsurr = -(ΔH) / T

We calculate as follows:

ΔSsurr = -13200 / 1337 = 9.87 J/ K mol

Hope this answers the question. Have a nice day.
