Answer:
The intensity of light from the first polarizer is 
Explanation:
The intensity of the unpolarized light is 
Generally the intensity of light that emerges from the first polarized light is

substituting values


To solve this problem we will apply trigonometric and optical concepts that allow us to obtain the minimum distance required. The resolution of the eye is given under the following condition,

Here,


With the values we have that the diameter will be,


The relation between the distance of the lights and the distance from the eye to the lamp is given under the function,

For small angles
, then

Here,
d = Distance between lights
L = Distance from eye to lamp



Therefore the distance will be 5.5km

Answer:
Acceleration
Explanation:
can you mark me brainlies
So, if an object travels in a curved path, it changes velocity, and, thus, accelerates. This acceleration must be tied to a force. ... Therefore, whenever an object travels in a curved path, there must be an unbalanced force acting upon it. It is important to understand that all this may occur without a change in speed.t
Answer:
2.45 x 10^-2
Explanation:
All numbers in scientific notation or standard form are written in the form
m × 10n, where m is a number between 1 and 10 ( 1 ≤ |m| < 10 ) and the exponent n is a positive or negative integer.
To convert 0.0245 into scientific notation, follow these steps:
Step 1) Move the decimal 2 times to right in the number so that the resulting number, m = 2.45, is greater than or equal to 1 but less than 10
Step 2) Since we moved the decimal to the right the exponent n is negative
n = -2
Step 3) Write in the scientific notation form m × 10n
= 2.45 × 10-2
Therefore,
2.45 × 10-2 is the scientific notation form of 0.0245 number and 2.45e-2 is the scientific e-notation form for 0.0245
