Explanation:

Hydraulic Pressure-Control, On-Off Deluge Valve

FP-400Y-5DC

The BERMAD model 400Y-5DC is an elastomeric, hydraulic line pressure operated deluge valve, designed specifically for advanced fire protection systems and the latest industry standards. The 400Y-5DC is activated by a hydraulically operated relay valve, through which opening and closing of the valve can be controlled either with a remote hydraulic command or with a wet pilot line with closed fusible plugs. An integral pressure reducing pilot valve ensures a precise, stable, pre-set downstream water pressure. The optional valve position indicator can include a limit switch suitable for Fire & Gas monitoring systems. The 400Y-5DC is ideal for systems that combine a remote wet pilot line with a high pressure water supply.

Newton's Law of Cooling states that the rate of cooling of an object is proportional to the temperature difference between the o

Hoochie [10]

Answer:

$\frac{dy}{dt}=k(y_t-R)$

Explanation:

According to Newton’s law of cooling, the rate of loss of heat from a body and the difference in the temperature of the body and its surroundings are proportional to each other.

$\frac{dy}{dt}=k(y_t-R)$

Here, $y_t$ represents temperature at time t, R as the room temperature, t as the independent variable, y as the dependent variable.

If a single circular loop of wire carries a current of 61 A and produces a magnetic field at its center with a magnitude of 1.70

Schach [20]

Answer:

The radius is $R = 0.22 5 \ m$

Explanation:

From the question we are told that

The current is $I = 61 \ A$

The magnetic field is $B = 1.70 *10^{-4} \ T$

Generally the magnetic field produced by a current carrying conductor is mathematically represented as

$B = \frac{\mu_o * I}{2 * R }$

=> $R = \frac{\mu_o * I }{ 2 * B }$

Here $\mu_o$ is the permeability of free space with value $\mu_o = 4\pi * 10^{-7} N/A^2$

=> $R = \frac{ 4\pi * 10^{-7} * 61 }{ 2 * 1.70 *10^{-4} }$

=> $R = 0.22 5 \ m$

If a star has no measurable parallax, what can you infer?.

Leni [432]

<span>If you can't measure the parallax that means that the star is far far away, beyond all possible reach of humanity with its current technology. The closer the star is the greater the parallax, so you either get a bigger, more powerful telescope, or you just accept that it's too far away to be measured at all. Eventually the technology will develop enough to measure it.</span>
