which machine changes the direction of force needed to do a task without changing the size of the force needed?

Two light sources can be adjusted to emit monochromatic light of any visible wavelength. The two sources are coherent, 2.04μm ap

tigry1 [53]

Answer:

Explanation:

Path difference for the observer = 2.04μm

For constructive interference

path difference = n λ

2.04μm = 5 x .408 or , 4 x .51 or 3 x .68μm

For visible wavelengths like .408 , .51 or .68 μm (400 to 700 nm) will the observer see the brightest light due to constructive interference.

B) If the two sources were not in line with the observer, but were still arranged so that one source is 2.04μm farther away from the observer than the other , in that case also , interference pattern will be visible .

c )

For destructive interference

2.04 μm = (2n+1)λ / 2

2.04μm = 3.5 x .58μm

2.04 μm = 4.5 x .45μm

So for .58μm and .45μm , destructive interference will take place

Paladinen [302]

Answer: At the antinodes of a standing wave, the wave is shaking very rapidly, causing those parts of the pizza to get hot. At the nodes, the wave is not shaking much at all, causing those parts of the pizza to stay cold."

Explanation:

antinodes vibrate and are the opposite of nodes which are stationary.

A total work of 3200 J is done to lift a container a distance of 2.40 m. What was the weight of the container? What was the mass

Diano4ka-milaya [45]

1) The weight of the object is 1333 N

2) The mass of the object is 136 kg

Explanation:

1)

The work done when lifting an object is equal to the change in gravitational potential energy of the object:

$W=Fd$
