Oceanic water particles mainly move in circles; is this movement greater on the ocean's surface or below the surface? Explain yo
goblinko [34]
I think that the oceanic water particles mainly move in circles greater in the oceans surface because of how big the waves can be and how wind and air impact the motion. The water particles move more on the surface because of the other factors that impact it such as people, wind, air, etc...

You want to reduce your energy bills.
aleksandr82 [10.1K]

Answer:

A. 100 Watts

B. 12 Watts

C. the first bulb

Explanation:

A. The formula for power is Work done/time

6000J/60seconds = 100J/s or 100W

B. Another formula for power is Current * Voltage

0.05*240 = 12W

Higher Current = ________ Moving Electric Charges (Electrons) *
Eva8 [605]

Answer:

Higher current is normally achieved by faster moving electrons.

Explanation:

  • Current is solely not the speed of the electric charges, but speed of the electrons is one of the factors that current depends on.
  • Current is the net charge flowing per unit time.
  • Current can be represented by:

            I=v×e×N×A

where,

                  I= current

                  e= electric charge

                  v= speed of electrons

                  N=no. of free electric charges per volume

  • The unit of current is Ampere, represented by A. It is flow of 1 coulomb of charge in 1 second.

A compressor receives air at 290 K, 100 kPa and a shaft work of 5.5 kW from a gasoline engine. It is to deliver a mass flow rate
Sladkaya [172]

Answer:

P_2=4091\ KPa

Explanation:

Given that

T₁ = 290 K

P₁ = 100 KPa

Power P =5.5 KW

mass flow rate

\dot{m}= 0.01\ kg/s

Lets take the exit temperature = T₂

We know that

P=\dot{m}\ C_p (T_2-T_1)

5.5=0.01\times 1.005(T_2-290})\\T_2=\dfrac{5.5}{0.01\times 1.005}+290\ K\\\\T_2=837.26\ K

If we assume that process inside the compressor is adiabatic then we can say that

\dfrac{T_2}{T_1}=\left(\dfrac{P_2}{P_1}\right)^{0.285}

\dfrac{837.26}{290}=\left(\dfrac{P_2}{100}\right)^{0.285}\\2.88=\left(\dfrac{P_2}{100}\right)^{0.285}\\

2.88^{\frac{1}{0.285}}=\dfrac{P_2}{100}

P_2=40.91\times 100 \ KPa

P_2=4091\ KPa

That is why the exit pressure will be 4091 KPa.
