Parallel circuits allow current to flow even if some paths are cut, because a parallel circuit has more than one current-carrying path through it.
Answer:
43.16°
Explanation:
λ = Wavelength = 1.4×10⁻¹⁰ m
θ₁ = 20°
n can be any integer
d = distance between the two slits
Since for the first bright fringe, n₁ = 1
n₂ = 2 for second order line
The relation between the distance of the slits and the angle through which it is passed is:
dsinθ=nλ
As d and λ are constant
∴ Angle by which the second order line appear is 43.16°

6.Make up most of the atom's mass
7.Atomic Number
8.Seven
The correct answer is D. learn to do a task independently.
Answer:
a) 9 - 1.2 = 7.8 N
b) Since the force exerted by the box is it's weight, it acts in a downward direction. So the box will exert a force downward (perpendicular to the horizontal surface).
Explanation:
A 9N block would exert 9N of normal force on the horizontal plane under normal conditions. But in this case, we have a spring taking away some of the force by applying an upward force on the box.
So the force exerted by the box on the surface would now be:
a) 9 - 1.2 = 7.8 N
b) Since the force exerted by the box is it's weight, it acts in a downward direction. So the box will exert a force downward (perpendicular to the horizontal surface).
