Unpolarized light shines pon a photocell for one hour. then, two polarizers, whose transmission axies are offset by 60, are plac

LenaWriter [7]

Answer:

t = 1.10 h

Explanation:

For this exercise we must calculate the intensity that reaches the cell with the polarizers, for this we use Malus's law

I = I₀ cos² θ

Let's calculate

I = I₀ cos² 60

I = I₀ 0.907

This is the intensity that reaches the cell

To find time, use an inverse proportion rule or rule of three, the intensity Io in

t = I₀ / (0.907 I₀) 1 h

t = 1.10 h

A body moves due north with velocity 40 m/s. A force is applied

marshall27 [118]

Answer:

the direction of rate of change of the momentum is against the motion of the body, that is, downward.

The applied force is also against the direction of motion of the body, downward.

Explanation:

The change in the momentum of a body, if the mass of the body is constant, is given by the following formula:

$\Delta p=\Delta (mv)\\\\\Delta p=m\Delta v$

p: momentum

m: mass

$\Delta v$ : change in the velocity

The sign of the change in the velocity determines the direction of rate of change. Then you have:

$\Delta v=v_2-v_1$

v2: final velocity = 35m/s

v1: initial velocity = 40m/s

$\Delta v =35m/s-40m/s=-5m/s$

Hence, the direction of rate of change of the momentum is against the motion of the body, that is, downward.

The applied force is also against the direction of motion of the body, downward.
