Answer:
Speed = 5 m/s
Explanation:
Distance (d) = 10 m
Time (t) = 2 s
Speed = Distance ÷ Time
Speed = 10 ÷ 2
<em><u>Speed = 5 m/s</u></em>
Length of wire (L)=2.35m
Mass of wire (m)=0.100kg(m)=0.100kg
Tension in the wire (T)=0.042m
<h3>
What is tension?</h3>
Any physical object that is in contact with another one can apply forces to that item. Depending on the sorts of objects in touch, we label these contact forces differently. We refer to the force as tension if a rope, string, chain, or cable is one of the things applying the force.
Ropes and cables can effectively convey a force over a long distance, making them valuable for exerting forces (e.g. the length of the rope). For instance, a team of Siberian Huskies can pull a sled by attaching ropes to them, allowing the dogs to move more freely than if they had to push against the sled's rear surface with their typical effort.

Because the action and the reaction forces act on different objects
Explanation:
Newton's third law of motion states that:
<em>"When an object A exerts a force on an object B (action), then object B exerts an equal and opposite force (reaction) on object A"</em>
From the statement above, we clearly see that the two forces mentioned in the law act on different objects. In fact, the action is exerted on object B, while the reaction is exerted on object A.
When we are considering the free-body diagram of an object, we just represent all the forces acting on that object, but not the forces exerted on other objects: this means that the action and the reaction never appear in the same free-body diagram of the same object, so they do not cancel out, simply because they are applied to different objects.

Answer:
(b) 32.2°
Explanation:
Using Snell's law as:
Where,
is the angle of incidence ( 30.0° )
is the angle of refraction ( ? )
is the refractive index of the refraction medium (Material B, n=5 / 4)
is the refractive index of the incidence medium (Material A, n=4 / 3)
Hence,
Angle of refraction = 
= 32.2°
