should be 1
Explanation:
because what do you use in class and has a lever
Answer:
False. It is propelled but projectile is a specific term denoting air friction only after release of energy.
Answer:
6.9066 × 10⁻⁵ m
Explanation:
For constructive interference, the expression is:
Where, m = 1, 2, .....
d is the distance between the slits.
The formula can be written as:
....1
The location of the bright fringe is determined by :
Where, L is the distance between the slit and the screen.
For small angle ,
So,
Formula becomes:
Using 1, we get:

Thus, the distance between the central maximum is 3.00 cm
First bright fringe , m = 1 occur at 3.00 / 2 = 1.50 cm
Since,
1 cm = 0.01 m
y = 0.0150 m
Given L = 2.00 m
λ = 518 nm
Since, 1 nm = 10⁻⁹ m
So,
λ = 518 × 10⁻⁹ m
Applying the formula as:

<u>⇒ d, distance between the slits = 6.9066 × 10⁻⁵ m</u>
Answer:
m₁/m₂ =8
Explanation:
Writing the centripetal force equation: where T₁ is inner tension and T₂ is outer tension
T₂ = m₂ × ω²R....equation 1
T₁-T₂ = m₁ × ω²R/2
Also T₁=5T₂
5T₂-T₂ = m₁ × ω²R/2
4 × 2T₂ = m₁ × ω²R
8T₂ = m₁ × ω²R
dividing it by equation 1
8 = m₁/m₂
Hence m₁/m₂ =8
False does not last that long
