Transverse waves travel with a speed of 20 m/s on a string under a tension 0f 6.00 N. What tension is required for a wave speed
Aleksandr [31]

Answer:

T_2=13.5\ N

Explanation:

Given that,

Speed of transverse wave, v₁ = 20 m/s

Tension in the string, T₁ = 6 N

Let T₂ is the tension required for a wave speed of 30 m/s on the same string. The speed of a transverse wave in a string is given by :

v=\sqrt{\dfrac{T}{\mu}}........(1)

T is the tension in the string

\mu is mass per unit length

It is clear from equation (1) that :

v\propto\sqrt{T}

\dfrac{v_1}{v_2}=\sqrt{\dfrac{T_1}{T_2}}

T_2=T_1\times (\dfrac{v_2}{v_1})^2

T_2=6\times (\dfrac{30}{20})^2

T_2=13.5\ N

So, the tension of 13.5 N is required for a wave speed of 30 m/s. Hence, this is the required solution.

In this reaction diagram which part represents the doffrence in energy between the reactants and the products?
Annette [7]

Answer:

The correct answer is - option C. G.

Explanation:

In this reaction diagram, there is a representation of the reaction profile. The reaction profile shows the change that takes place during a reaction in the energy of reactants or substrate and products. In this profile, activation energy looks like a hump in the line, and the minimum energy required to initiate the reaction.

The overall energy of the reaction, including or excluding activation energy depends on the nature of the reaction if it is exothermic or endothermic. and products are represented by the G which shows the difference between the energy of the reactants and products.
