Answer:

None of these is correct.

Explanation:

The wave particle duality has to do with Louis de Broglie's proposition that matter could exist as waves or particles.

According to him, matter poseses an associated wavelength. Hence, a certain wavelength is traceable to the hydrogen atom.

This wavelength is the ratio of Plank's constant to the momentum of the hydrogen atom

What is meant by the dead state. Discuss its significance.
Jlenok [28]

Answer and Explanation:

Dead state can be defined as the state in which both the are ambient properties and the system properties are coincident to each other.

Since the surroundings are similar and these surroundings are fixed also, there will be no kinetic energy and also the gravitational potential energy for both the systems is also equal.

Practically, in thermodynamic studies, the Gravitational potential energy of the system is negligible. This state holds significance because it leads to the termination of all the processes that are spontaneous in nature.

Wind blows on the side of a fully enclosed hospital located on open flat terrain where V= 120 mi/h. Determine the external press
ss7ja [257]

Answer:

The external pressure is p = -21.9 psf or p = -8.85 psf

Explanation:

Given :

Velocity of wind, v = 120 mi / hr

$k_d = k_c =1 $   (wind direction factor)

$k _{zt} = 1 $  = topographical factor (for flat terrain)

$ q_n$ = velocity pressure at height h

$ \therefore q_n = 0.00256 k_z k_{zt} k_d v^2 $

$  q_n = 0.00256 \times  k_z (1)(1)(120)^2 $

    $ = 36.86 k_z$

But for height h = 30 ft, $ k_z$ = 0.98 (from table)

$ \therefore q_n = 36.86 \times 0.98 $

        = 36.16

Now, $ \frac{L}{B}= \frac{200}{200} =1$ ,   so $C_p=-0.5 $ (from table)

$p = q(G)(C_p)-q_n(GC_{pi})$

where, p = external pressure

            G = 0.85 = gust factor (for typical rigid building)

            $GC_{pi} = \pm 0.18 $   (internal pressure co efficient)

Therefore putting the values,

$p = (36.13)(0.85)(-0.5)-(36.13)(\pm 0.18)$

p = -21.9 psf or p = -8.85 psf

What should you use to keep battery terminals from corroding
Ray Of Light [21]

Answer: Apply battery-terminal grease to the terminals to help prevent corrosion. It's available at any auto parts store and usually comes in a little ketchup-like packet. Another great option is AMSOIL Heavy-Duty Metal Protector. It creates a protective coating on terminals that wards off corrosion.
