The components are the sides S and W of a right triangle with SW = 5 km as the hypotenuse. It helps to sketch out these types problems.
Using the 60°south of west angle would make W adjacent and S opposite to the angle. using SOH CAH TOA
sin(60) = S/5
5*sin(60) = S
5*√(3)/2 = S
4.3 km = S
<span>A linearly polarized electromagnetic wave has an average intensity of 450 W/m2. This wave is directed towards two ideal polarizers (in real polarizers, transmission is also effected by reflection and absorption). Polarizer A is oriented with its transmission axis at an angle of θ1 = 32.6° with the incident electric field. Polarizer B has its axis at an angle of θ2 = 75.8° with the incident electric field, as shown in the figure.</span>
Answer:
7.75m/s or 
Explanation:
m = 1.5kg
u= 10m/s
s = 2m
a = 
v = ?
acceleration due to gravity is negative when an object is going up because the force of gravity reduces the speed of the object
using the formula ;
since the object is moving upwards (negative acceleration)
= 100 - 2(10)(2)
100 - 40
= 60
v = 
= 7.75m/s

No. of e- at a instant through given area is = total charge passing per
unit time/charge of e-
using i=q/t=(no.of e-(n))(1.6*10^-19)= 10
n=6.3*10^19 </span>
Answer:
Image formed by a <u>convex mirror</u> is always <u>virtual and erect</u>. When an object is placed at infinity, virtual image is formed at focus and the size of the image is <u>smaller</u>.
