Why is it that the weight of an object weighing 1N air, weighs more when immersed in water ?

There is no "why", because that's not what happens. The truth is
exactly the opposite.

Whatever the weight of a solid object is in air, that weight will appear
to be LESS when the object is immersed in water.

The object is lifted by a force equal to the weight of the fluid it displaces.
It displaces the same amount of air or water, and any amount of water
weighs more than the same amount of air. So the force that lifts the
object in water is greater than the force that lifts it in air, and the object
appears to weigh less in the water.

The average energy per unit time per unit area that reaches the upper atmosphere of the Earth from the Sun, called the solar con

Lynna [10]

Answer: 5.34 MJ

Explanation: The window is a rectangle with area:

A = 1.1(1.5)

A = 1.65 m²

We know that only 0.9 kW/m² reaches Earth so:

P = $0.9\frac{kW}{m^{2}}(1.65)m^{2}$

P = 1.485 x 10³ W

Watts is an unit of Power and it can also be written as J/s.

An hour has 3600s or 3.6 x 10³s, so:

E = 1.485 x 10³ $\frac{J}{s}$ (3.6 x 10³s)

E = 5.346 x 10⁶ J

Mega is equal to 10⁶, then:

E = 5.35 MJ

A 1.1 m by 1.5 m window collects, during 1 hour of daylight, 5.35 MJ

Características sobre los conectores SATA

Soloha48 [4]

Answer:

SATA tiene las siguientes características importantes: Voltaje reducido. Los estándares ATA actuales utilizan 5,0 V o 3,3 V (ATA-100/133). Estos voltajes relativamente altos junto con altas densidades de pines hacen que 100 MB / s sea la velocidad de datos más alta que se puede alcanzar de manera realista.
