This is a transform Boundrary
Kinetic energy is a form of energy that an object or particle has by reaction of its motion.
Answer:
W = 0.012 J
Explanation:
For this exercise let's use Hooke's law to find the spring constant
F = K Δx
K = F / Δx
K = 3 / (0.16 - 0.11)
K = 60 N / m
Work is defined by
W = F. x = F x cos θ
in this case the force and the displacement go in the same direction therefore the angle is zero and the cosine is equal to 1
W = ∫ F dx
W = k ∫ x dx
we integrate
W = k x² / 2
W = ½ k x²
let's calculate
W = ½ 60 (0.19 -0.17)²
W = 0.012 J
Answer:
Δx = 2.76 x 10⁻³ m = 2.76 mm
Explanation:
The distance between any two consecutive dark or consecutive bright fringes is given by:
Δx = λL/d
where,
Δx = distance between first and second dark fringe = ?
λ = wavelength of light = 546.1 nm = 546.1 x 10⁻⁹ m
L = distance between slits = 1.35 m
d = slit separation = 0.267 mm = 2.67 x 10⁻⁴ m
Therefore,
Δx = (546.1 x 10⁻⁹ m)(1.35 m)/(2.67 x 10⁻⁴ m)
<u>Δx = 2.76 x 10⁻³ m = 2.76 mm</u>
Answer:
1.76 m/s^2
Explanation:
The formula to find the force is F = ma (reference from 2nd law of Newton's Laws of Motion). Since you need to find the acceleration of the box, you need to use the formula a = f/m
a = 9.7 n divided by 5.5 kg = 1.76 m/s^2
