Answer:

wave speed= constant

frequency = increase

wavelength = decrease

Explanation:

Solution:

- The three basic parameters of a wave are speed, frequency and wavelength. These three parameters are related to each other by an expression:

                                             v = f * λ

Where,

- v is the speed of the wave in m/s.

- f frequency of the wave in Hz.

- λ wavelength of the wave in m

- We are asked how would each of these parameter change if we move the hand up and down faster. The hand moves from a crest to trough faster than before and back again. We can see that the time between a cycle has decreased; hence, frequency f increases. Consequently, we can see that wave speed v remains constant - the medium of transfer of wave energy - remains same. Then from our relation above if we hold speed constant and increase f then the wavelength λ would have to decrease.

If two objects are in thermal equilibrium, do they have the same thermal or internal energy?
Tpy6a [65]

Answer:

Yes, they do have the same internal energy.

Explanation:

The thermal balance refers to when there is no heat transfer between the bodies and their surroundings i.e. the bodies and the environment are at the same temperature.

Suppose two bodies of different masses and different materials, each one of them is at a temperature of 25(° C), which is the same temperature as the temperature of the environment, if these two bodies are close to each other, there is also heat transfer as they are at the same temperature, in the absence of any type of energy that enter or exit in these bodies, the amount of internal energy will be equal in both bodies.

Note: when the internal energy of one of these bodies is increased, heat transfer will happen, always looking for the thermal balance.

Es - Which of the these is a balanced chemical equation?
nalin [4]
<h3>Answer:</h3>

2CO(g) + O₂(g) → 2CO₂(g)

<h3>Explanation:</h3>

What is a  balanced chemical equation?

  • A balanced chemical equation is one that has equal number of atoms of each element involved in the reaction on both side of the equation.

How do we balance chemical equations?

  • Balancing chemical equations is a try and error process that involves putting appropriate coefficients on the reactants and products in a chemical reaction.

Why is it important to balance chemical equation?

  • Chemical equations are balanced so as to obey the law of conservation of mass.

In this case; the balanced chemical equation for the reaction between carbon monoxide and oxygen gas is given by;

2CO(g) + O₂(g) → 2CO₂(g)

  • This is because there are 2 carbon atoms and 4 oxygen atoms on both the reactant and product side.
