Answer ) Sound level equation

The intensity of a sound wave is related to its amplitude squared by the following relationship: I=(Δp)22ρvw I = ( Δ p ) 2 2 ρ v w . Here Δp is the pressure variation or pressure amplitude (half the difference between the maximum and minimum pressure in the sound wave) in units of pascals (Pa) or N/m2.

Answer:

45°

Explanation:

Let there are two vectors, A and B. The angle between the two vectors is θ.

The dot product of two vectors is equal to the vector product of two vectors.

$\left | \overrightarrow{A}.\overrightarrow{B} \right |=\left | \overrightarrow{A}\times \overrightarrow{B} \right |$

A B cosθ = A B Sinθ

tan θ = 1

θ = 45°

Thus, the angle between the two vectors is 45°

Under metric prefixes, if a meter were divided into 100 equal-sized subunits, a single unit would be called a

joja [24]

Answer:

In metric prefixes, if a meter were divided into 100 equal-sized subunits, a single unit would be called a centimeter.

Explanation:

Here we asked to divide 1 meter in to 100 equal parts.

Let us find out what is the length of piece when 1 m is divided in to 100 equal parts.

Length

$l = \frac{1}{100} = 0.01m$

That is length of 1 m divided into 100 equal parts is 0.01m.

We know that 0.01 m is 1 centimeter.

So, in metric prefixes, if a meter were divided into 100 equal-sized subunits, a single unit would be called a centimeter.

if a horse exerts a pulling force on a cart, is the reaction force the force of friction between the horse's feet and the road?

Assoli18 [71]

Answer:

A horse pushes the ground in a backward direction. According to Newton’s third law of motion, a reaction force is exerted on the horse in the forward direction. When the horse walks in the forward direction (with the cart attached to it), it exerts a force in the backward direction on the Earth. An equal force in the opposite direction (forward direction) is applied on the horse by the Earth. This force moves the horse and the cart forward. As a result, the cart moves forward.

Answer:

The current would stop

Explanation:

Electric currents are interesting because they carry little to no momentum. As soon as you remove a power source, the whole current halts.
