The answer is slows objects down.
Answer:
Displacement is the distance between an object’s initial position and its final position and is usually measured or defined along a straight line. Since this is a calculation that measures distance, the standard unit is the meter (m).
Explanation:
Answer: if the pressure in the container is doubled, then the temperature will double too.
Justification:
You can rely on Gay-Lussac's law for ideal gases to answer the question.
According to that law, the pressure and temperature of a fixed amount of gas in a closed rigid container (constant volume) varie in direct proportion.
Mathematically, you can write in this way:
P/T = k
P₁ / T₁ = P₂ / T₂
That means, that if the pressure in the container is doubled, then the temperature will double too.
You can see that mathematically:
P₂ = 2 P₁
T₂ = (T₁ / P₁)(P₂) = (T₁ / P₁) (2 P₁) = 2 T₁
Answer:
Explanation:
a ) If x be the position of n the bright fringe on the screen , following formula holds .
x = n (λD / d) ; λ is wave length , D is screen distance and d is slit separation .
If we increase the value of λ or wave length, x will increase so central fringe along with all the fringes will shift away from the centre .
If we increase the value of D or screen distance , it will also increase x , so fringes along with central fringe will shift away from the center.
b ) Fringes ,whether bright or dark , both shift together , either towards or away from the center .
So to move the dark spots towards the center , we need to do the opposite to what we did in the first case , ie decrease the wavelength or decrease the screen distance .
