Answer:
Interference
Explanation:
Interference is the phenomenon in which two waves superimpose to form a wave with smaller, larger or same amplitude.
There are two types of interference namely, constructive interference and destructive interference.
Constructive interference occurs when the waves are in phase and destructive interference occurs when the waves are out of phase.
In a double slit experiment, the two slits acts as sources of light and thus the waves combine to produce interference patterns. When the waves are in phase, that is the angle between them is 0°, they form a constructive interference pattern which gives rise to a light band. When the waves are out of phase, that is the angle between them is 180°, they form a destructive interference pattern which gives rise to a dark band.
Note also that diffraction patterns are also observed for wide slits but can be neglected for smaller slits.
answer:
6 ohms
Explanation:
if these two resistors are connected in series, the total resistance is the sum: 2+4 = 6 (ohms)
Answer:
option C and D
Explanation:
When a stunt driver is rotating on the banked road the force which is responsible for the centripetal acceleration of the car is Frictional force and the Normal Force.
The Frictional force component of the banked road will protect the car from skidding.
And the normal force component will protect the car from toppling inward due to centripetal force acting on it.
Hence, the correct answer is option C and D
Answer: 27.791 meters
Explanation: The precision of a measure depends on the number of significative decimals that it has, so the number that is most exact is the one with more numbers after the decimal point, in this case, is the third option: 27.791 m
This one is the most exact because you know that the lenght is:
27 meters, 7 centimetrs and 9.1 milimeters
Answer:
1 N
Explanation:
1) You'll just have to sum the force vectors, and since they are opposite, you'll calculate the difference of their magnitudes, in absolute value.
Ftot = |F1 - F2| = 6N - 5N = 1N
2)The direction will be the same as the greater force's direction.
