I’m pretty sure subpolar low goes with heavy precipitation, little wind. horse latitudes goes with two wind systems originate here. and intertropical convergence zone goes with convergence of westerlies and polar easterlies. that’s what i think, sorry if i’m wrong

a blackbody is at temperature of 500°C . What would be its temperature in Kelvin for it to radiate twice as much energy per seco
Firdavs [7]

Answer:

773.15K

Explanation:

Temperature is measured in different units, however, the standard or absolute temperature unit is Kelvin (K).

To convert the temperature of a black body, which is 500°C to Kelvin, we use;

T(K) = T(°C) + 273.15

T(K) = 500°C + 273.15

T(K) = 773.15K

Hence, the temperature of the blackbody at 500°C will be 773.15 K for it to radiate twice as much energy per second.

The water line from the street to my house is 1 inch diameter and made of PVC (i.e. smooth). The line is roughly 450 ft long. Th
jekas [21]

Answer:

The right solution is "126 Psi".

Explanation:

The given values are:

P₁ = 130 psig

i.e.,

   = 130\times 6.894

   = 896.22 \ Kpa

or,

   = 896.22\times 10^3 \ Pa

Z₂ = 10ft

    = 3.05 m

\delta = 1000 kg/m³

According to the question,

Z₁ = 0

V₁ = V₂

As we know,

⇒  \frac{P_1}{\delta_g} +\frac{V_1^2}{2g} +Z_1=\frac{P_2}{\delta_g} +\frac{V_2^2}{2g} +Z_2

On substituting the values, we get

⇒  \frac{P_1}{\delta_g} +0+0=\frac{P_2}{\delta_g} +0+Z_2

⇒  \frac{896.22\times 10^3}{1000\times 9.8} =\frac{P_2}{1000\times 9.8} +3.05

⇒  P_2=866330 \ P_a

i.e.,

⇒       =866330\times 0.000145

⇒       =126 \ Psi

If a wave has a frequency of 2 HZ what would it be in seconds?
gavmur [86]

Frequency is not a length of time.  It's exactly the opposite.
Frequency tells you how often something happens.  In fact,
the unit 'Hz' means 'per second'.

   Frequency of 2 Hz means "It happens at 2 per second."

The time it takes for the thing to happen once is exactly the
'reciprocal' of the frequency ... ' 1 ' divided by the frequency.

If the frequency is  2 Hz, then the thing happens every 1/2 second.

If the frequency is 74 Hz, then it happens every  1/74 of a second.

If the frequency is 1 KiloHz, then it happens every  1/1000 second.

Technician A says that the rotary engine is not an internal combustion engine, because it does not use pistons. Technician B say
Rama09 [41]

Answer:

Technician B

Step-by-step explanation:

Rotary engine, also known as Wankel, is an internal combustion engine as the definition of inernal combustion is <em>any machine that uses energy from chemical links and transforms it in mechanical work through combustion inside it.</em>

The rotary engine gets three power pulses for each rotation because it can compress, intake/exhaust, and expand at the time in diferent parts of the engine, separated by the tree edges of the triangular rotor.
