Light will pass through a pair of Polaroids when the axes are aligned. Because each polaroid can only pass light waves in one direction through it - either horizontal or vertical. If the axes are aligned at right angles to each other, then the horizontal polaroid will not allow the vertical light waves to pass, while the vertical polaroid will not allow the horizontal light waves to pass. Therefore light cannot pass through a pair of polaroids when the axes are at right angles to each other.
Explanation :
An electrical circuit can be either connected in series or parallel.
Series combination: The current flowing in each resistor is the same and the equivalent resistance is given by :
Parallel combination: The voltage for all components in the parallel combination is the same. The equivalent resistance is given by :
So, our of given options the correct one is (b) because the current flowing in both the resistors is the same.
Answer:
<h2>0.17 m/s²</h2>
Explanation:
The acceleration of an object given it's mass and the force acting on it can be found by using the formula
f is the force
m is the mass
From the question we have
We have the final answer as
<h3>0.17 m/s²</h3>
