What happens to parallel light rays that strike a concave lens?

Answers

Answer 1
Answer: When parallel light rays comes across a concave lens, the rays are refracted outwards. Concave lenses are thinner in the middle part. Parallel light rays diverge and seems to appear from one point called the principal focus. The image formed is smaller. 
Answer 2
Answer:

Answer:

The light ray that pass through the lens diverge and is refracted outwards and never meets at a focal point.

Explanation:

Divergent lenses (also called concave lenses) are transparent bodies bounded by two refractory surfaces with one central axis in common. When a parallel light ray strikes a lens, it is refracted by changing its direction, this refraction in the divergent lens causes the rays to move away from the central axis, ie the ray of light passing through the lens diverges and is refracted outward. and is never at a focal point.

What occurs when someone places an ice pack on an injured ankle?Conduction causes the ice pack to lose thermal energy.
Conduction causes the ankle to gain thermal energy.
Cold from the ice pack is transferred to the ankle.
Heat from the ankle is transferred to the ice pack.

Answers

The answer is:

Heat from the ankle is transferred to the ice pack.

The explanation:

-when the ice pack  a lower temp than the ankle , it is very cool.

- and the injured ankle has a high temp or heat

and we know that Q transfer from the object with high heat to the object with the low temp So,

Heat will transfer from the ankle to the ice pack.

When someone places an ice pack on an injured ankle is : ( D ) Heat from the ankle is transferred to the ice pack  

Conduction

Conduction is the transfer of heat energy from a higher temperature body to lower region or body. The temperature of the Ice pack is lower than the temperature of the ankle therefore we cannot say conduction caused the ice pack to lose thermal energy rather the heat from the ankle is transferred to the ice pack because the ankle has a higher temperature compared to the ice pack.

Hence we can conclude that When someone places an ice pack on an injured ankle is Heat from the ankle is transferred to the ice pack.

A particle with velocity v(t)=1/t​−3, in m/s, moves in a straight line. Its initial displacement is known to be s(1)=1, in m. Find the position function s(t).

Answers

Answer:

s(t) = (t1 - t2)* [((1/t1 - 3) + (1/t0 - 3))/2]

Explanation:

We will assume that v(t) is in units of m/s and t (time) is in seconds.

v(t)=1/t​−3

At time 0 (initial) the equation tells us the particle has a velocity of

v(t)=1/t​−3

v(0)=1/(0)​−3

v(0) = - 3 m/s

The particle is moving from right to left (the negative sign) at a rate of 3 m/s.

The position of the particle would be the average velocity times the time traveled.

Distance = Velocity x Time  (with Velocity being the average between times t0 and t1)

We'll use s(t) for displacement for time t.

 s(t) = v*t

We need the average velocity for the time period t0 to t1.

Let t0 and t1 be the initial and final times in which the measurement takes place.

At time t0 the velocity is = 1/t0 - 3

At time t1 the velocity is = 1/t1 - 3

The displacement is the average velocity between the two points, t0 and t1.  This can be written as:

 [(1/t1 - 3) + (1/t0 - 3)/\]/2

Displacement: s(t) = (t1 - t2)* [((1/t1 - 3) + (1/t0 - 3))/2]
