Answer:
(d/λ) = 17.67
Explanation:
Equation for double-slit:
d*sinθ = m*λ
Rearrange the equation
(d/λ) = m/(sinθ)
Since it is at the second dark fringe, m = 2
Therefore:
(d/λ) = 2/(sin(6.5)
(d/λ) = 17.67
Answer:
TRUE
Explanation:
BECAUSE AN OBJECTS DENSITY SHOWS HOW MUCH WEIGHT IS PER CUBIC UNIT. LIKE SAD HAS MORE DENSITY THAN WATER SO IT SINKS WHILE WOOD HAS LESS DENSITY THAN WATER SO IT FLOATS
Answer:
Weight of the fluid that the object displaces.
Explanation:
When the fluid is completely immersed in a fluid, it experiences pressure from all the direction. While the object is immersed in the fluid a force acts on it in the opposite direction, i.e., upwards. This force is termed as buoyant force.
Also, as per the Archimedes' Principle, the force experience by the object is the same as the weight of the fluid that gets displaced by the object.
Thus on complete immersion of the object in the fluid, it experiences the force same as the weight of the fluid that gets displaced
