Answer:
The distance between first-order and second-order bright fringes is 12.66mm.
Explanation:
The physicist Thomas Young establishes through its double slit experiment a relationship between the interference (constructive or destructive) of a wave, the separation between the slits, the distance between the two slits to the screen and the wavelength.
(1)
Where 
is the distance between two adjacent maxima, L is the distance of the screen from the slits, 
is the wavelength and d is the separation between the slits.
The values for this particular case are:
Notice that is necessary to express L and in units of milimeters.
⇒ 
⇒ 
Finally, equation 1 can be used:
Hence, the distance between first-order and second-order bright fringes is 12.66mm.
Answer:
1.85 m/s
102.438 m
Explanation:
From vector motion
The resultant velocity
The magnitude of speed of the speed of the boat relative to a stationary shore observer is 1.85 m/s
The distance covered is 229 m
Time = Distance / Speed
Distance = Speed of current × Time
Distance = 0.756×135.5 = 102.438 m
The boat will be 102.438 m from the initial position is the boat when it reaches the opposite shore
The answer is: [D]: "force".

Answer:
<em>Thermal energy</em>
Explanation:
<u>Electrical Energy
</u>
The electrical energy has been found to be an excellent resource to power our modern lifestyle. It can be produced in several ways including hydroelectrical plants, thermal plants, nuclear plants, solar panels, among many others. Each one of them converts different types of energy into electrical energy.
When converting to electrical energy, some equipment is needed, like generators, transformers, cables, circuit breakers, and every kind of devices with specific functions to have a good and safe electrical service. Each device has an internal resistance that opposes the flow of current. The resistances produce thermal energy as a result of current flowing through them. It's not possible to avoid this waste of energy, electrical engineers do their best to use better materials and configurations to reduce the thermal waste to a minimum.
Answer:
B. the force of on the truck due to the collision is exactly equal to the force on the car.
Explanation:
At the time of collision between two objects of unequal or equal masses two forces emerge at the point of collision .They are called action and reaction force . According to third law of Newton , they are equal . So in the instant case of collision between car and truck , force on both of them will be equal.
