Answer:
K = .3941 × 10³ W/m.K
Explanation:
Qcond = K A ΔT÷ L
∴K = Qcond ×L ÷ A ΔT
J ÷ S = P
P = I × V =Qcond
∴Qcond = I × V
= 0.6 A × 110 V
=66 W
L = 0.12 m
ΔT = 8 °C
Qcond =33 V
Area = (πD²) ÷ 4
= [π (4 × 10⁻² )²] ÷ 4
= 1.256 × 10⁻³ m²
∴A = 1.256 × 10 ⁻³³ m²
So K = ( Qcond × L ) ÷ A ΔT
= (33) (0.12 ) ÷ (1.256 ×10⁻³ ) × 8
= 0.3941 × 10³ W/m .K
Answer:
d = m× λ⇒ d = λ ×m×l / x
= 630× m × 3×3m/ 45× m
= 1.26×m
Explanation:
the above calculation is based on Young’s double slit experiment where the two slits provide two coherent light sources which results either constructive interference or destructive interference when passing through a double slit.
(a) -1.208 m
The position of the particle at time t is given by
where:
is the initial position
is the initial velocity
is the acceleration
Substituting into the equation t=3.70 s, we find the position after 3.70 seconds:
(b) -0.838 m/s
The velocity of the particle at time t is given by:
where
is the initial velocity
is the acceleration
Substituting t = 3.70 s, we find the velocity after 3.70 seconds:
1. b An element is the simplest form of a substance.
3. a Atoms are comprised of particles such as protons, neutrons, and electrons.
2. c Atoms are tiny pieces of matter.
4. d Phase refers to the state of matter: gas, liquid, and solid.
