<h3>Answer: 22.48°</h3><h3 /><h3>Explanation:</h3>

refractive index = sin i / sin e

where i is the angle of incidence

e is the angle of refraction

1.5 = sin 35 / sin e

1.5 = 0.5736/sin e

sin e = 0.5736/ 1.5

sin e = 0.3824

e = 22.48°

The object moves with BLANK from A to B. it BLANK from B to C. it moves with BLANK from C to D.
Ganezh [65]

Note that this is a position vs time graph.

From A to B, the graph is a straight line with a nonzero slope. This indicates a constant velocity.

From B to C, the graph is a straight line with 0 slope. This indicates a constant position, i.e. the object remains stationary.

From C to D, the graph is a straight line with a nonzero slope. This indicates a constant velocity.

If two persons do the same amount of work , they may have different power ? why ? ​
iris [78.8K]

Hey there mate :)

Even if two persons are given the same work load, the speed of the work done gets different by the energy of those persons.

No one is sure that he/she can complete the work within the time. He may or may not.

Also, the physical characteristics makes the work different. If one person has so much power to work all day, the other person may not have.

Therefore, <em>even if two persons do the same amount of work , they may have different power</em><em>.</em>

804 n of force are applied to a 51.7 kg. What is the acceleration that the object experiences?
Andreyy89

We can use Newton II here  (where F=m*a), that F is the net (or resultant) force on the object, m is the mass of the object and a is the acceleration the object experiences.

This means, in this case there would be no friction and absolutely no other force which gives a component in the plane of motion, only then can you assume that F=804N.

Now using F= m*a

804 = 51.7*a

Therefore a = 804/51.7 = 15.55 m/s²

Which idea did Ptolemy's model use to explain why the planets appeared to move backward as they moved in their orbits? The plane
ruslelena [56]

Answer:

The planets spun in epicycles.

Explanation:

The planets were not simply attached to a mystical sphere (“deferent”) but they were actually attached to a mini-sphere (“epicycle”) which rotated on the larger one.
