Sunlight, with an intensity of 667 W / m², strikes a flat collecting surface perpendicularly and is totally absorbed. The area o
alexandr1967 [171]

Answer:

F = 20.07 μN

Explanation:

given,                                            

intensity of sunlight = 667 W/m²

area of surface =  9.03 m²

speed of light = 3 x 10⁸ m/s

force = ?                                  

we know                                                                

force =intensity \times \dfrac{Area}{speed of light}

force =667 \times \dfrac{9.03}{3\times 10^8}

F = 20.07 x 10⁻⁶ N

F = 20.07 μN

Which of the following statements about a metal wire in equilibrium are true? Select all that apply. There cannot be excess char
olga_2 [115]

Answer:

There may be excess charges in the interior of the wire

The net electric field everywhere inside the wire is zero

The interior of the metal wire is neutral.

There may be excess charges on the surface of the wire.

There is no net flow of mobile electrons inside the wire.

Explanation:

For any metal wire in equilibrium position, there may be excess charges in the interior of the wire and the net electric field everywhere inside the wire is zero. Additionally, the interior of the metal wire is always neutral and there is likely to be excess charges on the surface of the wire. Moreover, it's important to note that for a metal wire in equilibrium, there is no net flow of mobile electrons inside the wire.

In what condition do acceleration and deaccelration<br>​
Vera_Pavlovna [14]

Im not sure what are you asking about. But in physic/ mechanic usually when the object against gravity, its deceleration but when the object follow the gravity its acceleration

Also usually when the object move to the left side the speed will be negative (-) this is probably because of deceleration? since deceleration = -acceleration.
