The false statement would be :
C. constructive interference occurs when the crest of one wave overlaps the trough of another and their individual effects are reduced or cancelled out.

Constructive interference should be when the crest of one wave overlaps another and their individual effects are add up, becoming a single wave of increased amplitude<span />

There are three long parallel wires arranged so that, in cross-section, they occupy the points of an equilateral triangle. Is th
Harrizon [31]

Answer:

Yes, there is such a way.

Explanation:

If currents flow in the same direction in two or more long parallel wires, there will be an attractive force between the wires. If the current flows in different directions, there will be a repulsive force between the wires. In this case, these three parallel wires, can be be made to carry current in the same direction, creating an attractive force between all three wires.

Note that it is not possible to have at the least one of them carry current in the opposite direction and still have an attractive current between them.

Projectile motion physics question 11 please​
kari74 [83]

Answer:

tair = 11.5 s

vi = 60.3 m/s

Explanation:

In the x direction:

Given:

x₀ = 0 m

x = 600 m

v₀ = v cos 30° = v √3/2

a = 0 m/s²

x = x₀ + v₀ t + ½ at²

600 = 0 + (v √3/2) t + ½ (0) t²

600 = √3/2 v t

1200/√3 = v t

In the y direction:

Given:

y₀ = 300 m

y = 0 m

v₀ = v sin 30° = v/2

a = -9.8 m/s²

y = y₀ + v₀ t + ½ at²

0 = 300 + (v/2) t + ½ (-9.8) t²

0 = 300 + 1/2 v t − 4.9t²

Substitute:

0 = 300 + 1/2 (1200/√3) − 4.9t²

0 = 300 + 600/√3 − 4.9t²

4.9t² = 300 + 600/√3

t = 11.5 s

Solve for v:

v t = 1200/√3

v = 60.3 m/s
