According to the law of refraction, what is the relationship between the angle of incidence and the angle of reflection
Vedmedyk [2.9K]
The relation between the angle of incidence and the angle of refraction is known as Snell's Law. Since the light travels with different speed in different media, the direction of the ray of light will change when it crosses the boundary between the two media

Find the acute angles between the curves at their points of intersection. (The angle between two curves is the angle between the
ladessa [460]

Answer:

1.190390345 degrees.

Explanation:

As stated in the problem that the angle between the two curves is also the angle between slopes of the two cures at the point of intersection, which is 1 (when we set two equation equal and solve for x).

We know, if you don't  you could verify it for yourself and it will be a nice mathematical exercise for you, that when there are two lines with slopes m_1 and m_2 then the angle between them and their two slopes has following relationship.

tan(\alpha ) = |\frac{m_2-m_1}{1+m_1m_2}|   where \alpha is angle between the two lines.

As it is clear that we can easily get the angle between the two curves if we know slopes at that point, which you will see in second is very straight forward to calculate.

Slopes are simply derivatives evaluated at the point of intersection and the two derivatives are D_1 16x and D_2 =24x^2, substituting x =1 we get, m_1 = 16 and m_2 = 24.

Now put m_1 and m_2 in this relationship, rearrange and solve for angle, it will come out to be

\alpha = 1.190390345 degrees.

that is our angle that we want to know between the two cures at the point of their intersection.

How fast or slow an object is moving and in what direction
Svet_ta [14]
<span>A moving object can be described by its velocity. Velocity is how fast an object is moving. Known as speed AND in what direction. A plus  or minus sign is often used as an indicator of direction. So an object with a velocity of -34 m/s is moving with a speed of 34 m/s in. the - direction.</span>
