I think the right answer would be objects pull because gravitational pull is when an object with more mass than an other object would pull the small mass object
<h2>
Depth of river is 4.48 m</h2>
Explanation:
Discharge = Area x Velocity
Discharge of river = Discharge of stream 1 + Discharge of stream 2
Area of stream 1 = w₁ x d₁ = 8.9 x 3.8 = 33.82 m²
Area of stream 2 = w₂ x d₂ = 6.5 x 3.9 = 25.35 m²
Velocity of stream 1 = 2.3 m/s
Velocity of stream 2 = 2.6 m/s
Velocity of river = 3 m/s
Substituting
Depth of river = 4.48 m
The law of reflection states that when a ray of light reflects off a surface, the <em>angle of incidence is equal to the angle of reflection</em>.
In this question, the light ray passes from air to water, an optically denser medium.
Imagine drawing a line to representing the boundary between two mediums. Now imagine drawing a line perpendicular to that boundary line marking where the light ray intersects the boundary line. This second line is called the normal. Whenever a light ray passes into a denser medium with a nonzero angle of incidence, the ray will bend towards the normal, making the <em>angle of refraction smaller than the angle of incidence</em>.
Choice A
Answer: Well there is a simple solution which is death..
This is possible due to inertia of motion. which is nothing but newton's first law.
according to this law , an object tries to retain its state of motion or rest unless acted upon by an external force.
consider an object placed on a paper, initially both the object and paper are at rest. to pull the paper , we apply force on the paper and paper gains velocity. but the object keeps its motion of rest and hence the paper can be removed without moving the object.
