A laser produces light at 5.32x10-7 m.

Physics
1 answer:
Blababa [14]3 years ago
6 0

Answer:

D

Explanation:

speed = frequency x wavelength

speed of light in vacuum is 3.0 x 10^8

wavelength = 5.32 x10 ^-7

3.0 x 10 ^ 8 = 5.32 x 10^-7 x frequency

frequency = 5.63909 x 10^14

round it off = 5.64 x 10^14 Hz

thus the answer is D

hope this helps please mark it

Real world situation to explain the relationship between work and power
In-s [12.5K]
-- You and your partner both get the same job to do:

Each of you gets a pallet of bricks, and you have to
put the bricks up on the bed of a truck, by hand.
Both pallets have the same number of bricks.

The pallet is way too heavy to lift, so you both cut the bands
that hold the bricks, and you lift the bricks from the pallet onto
the truck, by hand, two or three or four bricks at a time.

-- You get your pallet of bricks onto the truck in 45 minutes.

-- Your partner gets his pallet of bricks onto the truck in 3 days.

-- Work = (force) times (distance).

    You and your partner both lifted the same amount of weight
     up to the same height.  You both did the same amount of work.

-- Power = (work done) divided by (time it takes to do the work) .

  
Your partner took roughly 96 times as long as you took
   to do the same amount of work. 
   You did it faster.  He did it slower.
   You produced more power.  He produced less power.

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.
