Answer:
perpendicular
Explanation:
Polaroids are the material that is used to polarize the ray of light. Polaroid consists of microcrystals of herapathite.
When unpolarized light is passed through the Polaroid then ray appears to be of half the intensity and vibration of the ray in the single plane so, the emerged light is known as polarized light
Polaroids are used in the glasses to protect the eye from unwanted rays.
When Light does not pass through a pair of Polaroids then the axis of Polaroids will be perpendicular to the axis of ray.
Answer:
I gotchu fam. 0.0435 kg
Explanation:
m1v1+m2v2=m1v1f+m2v2f
(0.5)(23)+(m2)(0)=(0.5)(17)+(m2)(69)
11.5=8.5+69m2
3=69m2
0.0435 kg
Answer:
Explanation:
Volume of lead object = volume of aluminium object = V
mass of lead object > mass of aluminium object
When both the objects immersed in water, the buoyant force acting on both the objects.
Buoyant force = Volume immersed x density of water x gravity
As the volume of both the objects is same, so the buoyant force acting on both the objects is same.
So, weight in air of lead object is more than the weight in air of aluminium object.
Answer:
Distance covered by B is 4 times distance covered by A
Explanation:
For an object in free fall starting from rest, the distance covered by the object in a time t is
where
s is the distance covered
g is the acceleration due to gravity
t is the time elapsed
In this problem:
- Object A falls through a distance 
during a time t, so the distance covered by object A is
- Object B falls through a distance 
during a time 2t, so the distance covered by object B is
So, the distance covered by object B is 4 times the distance covered by object A.
