True or False? The superposition or overlapping of two waves always results in destructive interference between the different wa
san4es73 [151]

Answer:

Explanation:

False

When two waves overlap or superimpose over each other then they either undergo Constructive or destructive interference.

waves are the disturbance created by a force and add up to gives constructive interference when they are in the same line i.e. in the same phase.

When these disturbances are in the opposite phase then they superimpose to give destructive interference where the amplitude of the resulting wave will be much smaller as compared to original waves.

A wire with a current of 3.40 A is to be formed into a circular loop of one turn. If the required value of the magnetic field at
Sloan [31]

Answer:

0.107 m

Explanation:

The magnetic field at the center of a current-carrying loop is given by

B=\frac{\mu_0 I}{2r}

where

\mu_0 is the vacuum permeability

I is the current

r is the radius of the loop

In this problem we have

I = 3.40 A is the current in the loop

B=20 \mu T=20\cdot 10^{-6}T is the magnetic field at the centre of the loop

So, solving the formula for r we find

r=\frac{\mu_0 I}{2B}=\frac{(12.56\cdot 10^{-7} H/m)(3.40 A)}{2(20\cdot 10^{-6} T)}=0.107 m

A body of mass m1 = 1.5 kg moving along a directed axis in the positive sense with a velocity
larisa86 [58]

Answer:

3.71 m/s in the negative direction

Explanation:

From collisions in momentum, we can establish the formula required here which is;

m1•u1 + m2•v2 = m1•v1 + m2•v2

Now, we are given;

m1 = 1.5 kg

m2 = 14 kg

u1 = 11 m/s

v1 = -1 m/s (negative due to the negative direction it is approaching)

u2 = -5 m/s (negative due to the negative direction it is moving)

Thus;

(1.5 × 11) + (14 × -5) = (1.5 × -1) + (14 × v2)

This gives;

16.5 - 70 = -1.5 + 14v2

Rearranging, we have;

16.5 + 1.5 - 70 = 14v2

-52 = 14v2

v2 = - 52/14

v2 = 3.71 m/s in the negative direction
