Answer:

<h2>Here is the answer ..............</h2>

Explanation:

{A}

P1=MVcos 30

P2=MVcos 30

P=2 mvocs 30

P=square root 3 mv

f1=2mv/t

force on the wall =2

f2=square root of 3mv/t

so that f1 is greater than or [ > ] f2

Answer:

(A)

Explanation:

P1 = MVcos 30

P2 = MVcos 30

️P = -2 mvcos 30

️P = - square root of 3 mv

f1 = 2mv/ ️t

force on the wall = 2

f2 = square root of 3mv/ ️t, so f1 > f2

List at least three pieces of evidence to support the idea that sound is a wave.
Schach [20]

Answer:

1. It undergoes reflection. 2. It undergoes refraction. 3. It undergoes diffraction.

Explanation:

1. It undergoes reflection. This is because it bounces off surfaces when incident on them.

2. It undergoes refraction. This is because it changes direction when it passes from one medium to another

3. It undergoes diffraction. This is because it spreads out when it passes through doors and windows similar in dimension to the dimensions of its wavelength

A block is pulled along a horizontal surface at a constant speed by a force (14.1i 0 j 5.1k). The direction k is perpendicular t
Pepsi [2]

Answer:

W =84.6\ Nm

Explanation:

given,

F = 14.1 i + 0 j + 5.1 k

displacement = 6 m

Assuming block is moving in x- direction

we know,

 dW = F dx

\int dW = F\int dx

W = F\int_0^6 dx

W = F[x]_0^6

W = 14.1 \times 6

W =84.6\ Nm

hence, work done by the force is equal to W =84.6\ Nm
