KatRina [158]

Answer:

Infinity

Explanation:

When you have a limit approaching infinity one method you can use is to remember that the highest power dominants all of the other ones so when we have (t^2)/t-1 like in your problem, we see that t^2 has the highest power of 2 so if that's going to infinity and it's not being divided by any powers higher than it will just be inifinity.

A cellphone charger has a transformer with 2000 turns in the primary coil which converts 240v a.c to 6v a.c and a rectifier that
inn [45]

Answer:

As we are converting 220V AC into a 5V DC, first we need a step-down transformer to reduce such high voltage. Here we have used 9-0-9 1A step-down transformer, which convert 220V AC to 9V AC. In transformer there are primary and secondary coils which step up or step down the voltage according to the no of turn in the coils.

Selection of proper transformer is very important. Current rating depends upon the Current requirement of Load circuit (circuit which will use the generate DC). The voltage rating should be more than the required voltage. Means if we need 5V DC, transformer should at least have a rating of 7V, because voltage regulator IC 7805 at least need 2V more i.e. 7V to provide a 5V voltage.

Mark all the fermions a) Proton b) Electron c)Anti-top d) Gluon e) Tau Neutrino
aliya0001 [1]

Answer:

(a) Proton, (b) Electron (c) tau neutrino.

Explanation:

Elementary particles are the particles without any sub-structure which means they are not composed of other particles.

The elementary particles are classified into three categories which are discussed below:

(1) Quarks: up, down, top, bottom, strange, and charm.

(2) Leptons: electrons, electron neutrino, muon, muon neutrino, tau, tau neutrino.

(3) Bosons: Guon, photons Z bosons, W bosons, Higgs.

Fermions are particles that follow Fermi-Dirac statistics. Fermions consist of all the quarks and leptons. And fermions can also be categorized in elementary particles such as electrons and protons.

Therefore, the fermions in the given question are proton, electron, and tau neutrino.

Water flows steadily through a fire hose and nozzle. The hose is 78 mm inside diameter, and the nozzle tip is 20 mm I.D.; water
IgorC [24]

Answer:

The reaction force is 2.776kN as the force is negative and on the left of the Control Volume this indicates that the coupling in in tension.

Explanation:

By applying the continuity equation as

A_1V_1=A_2V_2\\

By simplifying the equation

V_1=V_2(\frac{D_2}{D_1})^2

Here

V_2=43 m/2

D1=78 mm

D2=20 mm

So the velocity is given as

V_1=V_2(\frac{D_2}{D_1})^2\\V_1=2.827 m/s

Now by applying the equation of momentum in x direction

R_x=-P_{1g}A_1+\rho V_1^2A_1-\rho V_2^2A_2

Here

  • P1g is given as 427 kPa
  • A1 is given by \pi D_1^2/4=\pi (78/1000)^2/4=0.00477 m^2
  • ρ is the density of water given as 1000 kg/m3
  • V1 is calculated above as 2.827 m/s
  • V2 is given as 42 m/s
  • A2 is given by \pi D_2^2/4=\pi (20/1000)^2/4=0.00031 m^2

Substituting the values in the equation gives

R_x=-P_{1g}A_1+\rho V_1^2A_1-\rho V_2^2A_2\\R_x=-(470 \times 10^3)(0.00477)+(1000) (2.827)^2(0.00477)-(1000) (43)^2(0.00031)\\R_x=-2776.96 N

So the reaction force is 2.776kN as the force is negative and on the left of the Control Volume this indicates that the coupling in in tension.
